Technical Centre for the Metalworking Industry,Uni¨ersitaire Campus,3590Diepenbeek,BelgiumAbstractDifferent types of anti-sticking coatings have been applied industrially on injection moulds for various types of plastics.Very often these tests are being done on a trial-and-error basis and results obtained are difficult to interpret.WTCM r CRIF has developed laboratory equipment where the injection moulding process can be simulated and demoulding forces and friction coefficients can be measured.These measurements were compared with surface energy calculations of the coated surfaces and of the plastic materials in order tofind a ing this approach it must be possible to make an easy and cheap selection of promising coatings towards plastic injection moulding.Another important advantage is that the understanding and modelling of the mould᎐plastic interface becomes possible.This new way of coating selection for plastic injection moulding has been demonstrated for various PVD coatings and verified for different industrial injection moulding applications.Keywords:Injection moulding;PVD coating;Modeling;Surface energy1.IntroductionPVD coatings have found their way into industry for several applications like metal cutting and deep draw-ing.Their use in plastic injection moulds has given bothw xpositive and negative results1᎐3.The unreproducible character of the results hinders further implementation in industry.To valorise the intrinsically good coating properties like chemical in-ertness vs.plastics to enhance demoulding,more in-sight is needed into the mechanism of interaction between the mould surface and the plastic material during injection moulding.To our knowledge,a systematic study of the influ-ence of mould surface roughness,mould coating, properties of the polymer like Young’s modulus,sur-face energy,polarity,structures,etc.on possible bind-ing mechanisms between the mould surface and the plastic material has never been carried out.This makes it practically impossible to understand demouldingU Corresponding author.Tel.:q32-11-26-88-26;fax:q32-11-26-88-99.mechanisms and,as a consequence of this,to select a proper coating for the injection mould.The purpose of this work was to try to simulate the injection moulding process in the laboratory and to correlate the results with surface energy measurements of the coated mould and of the plastic material.This could result in an approach to select the proper coating for a certain kind of plastic to be injected.2.Experimental detailsLaboratory equipment has been built to measure demoulding forces and friction coefficients.The mould itself is made out of tool steel1.2083and has a diame-Ž.ter of64mm and a height of30mm Fig.1.The thickness of the moulded part is2mm.A pressure sensor measures the demoulding forces.The tempera-ture inside the mould is measured by thermocouples as presented in Fig.1.All moulds were hardened to a hardness of56HRC.After a running-in period of40injections,the de-moulding force was measured10times for each coat-ing᎐plastic material combination.()M.Van Stappen et al.r Surface and Coatings Technology 142᎐1442001143᎐145144Fig.1.A cylindrical plastic part injection moulded around a mould.Surface energy was measured on the surface of the coating and on the surface of the plastic material using the model of Owens and Wendt.A Digidrop GBX apparatus has been used based on water and di-iodomethane as testing liquids.To measure the total surface energy,the dispersive surface energy and the polar surface energy are measured.Injection moulding was carried out as follows.In the first application,a polyurethane plastic material with tradename DESMOPAN 385S was injection moulded using uncoated moulds and moulds coated with,respec-tively,a TiN and a CrN coating.In the second applica-tion,three types of polymers were tested on a TiN coated mould and an uncoated mould.Two elastomers Žtrade name HYTREL G 3548W,which is a block-copolyester,and SANTOPRENE 101-73,which is a .blend of polypropylene and EPDM ,and EVOPRENE,which consists of polystyrene and butadiene.3.Results and discussionThe demoulding forces measured for the first appli-cation are given in Table 1.The demoulding forces for the second application are given in Fig.2.This demoulding behaviour has also been observed in industrial practice,so the demoulding laboratory apparatusis a good simulation of reality.To explain these results,an attempt was made to find a correlation with the surface energy measurements.Both total surface energy as well as polar surfaceTable 1Ž.Demoulding forces N for DESMOPAN Uncoated mould 7757N TiN coated mould -2810N CrN coated mould<415NŽ.Fig. 2.Demoulding forces in N for three materials:HYTREL,EVOPRENE,SANTOPRENE.energy in mJ r m 2were compared for both coated sur-Ž.faces and plastic materials Fig.3.In order to explain the demoulding behaviour,an attempt was made to make a correlation between de-moulding forces measured and the surface energy val-ues.It should be expected that when the surface energy of the coated surface is lower than the surface energy of the plastic material,an easy demoulding behaviour could result as a consequence of low material affinity between coating and plastic material.Because the ratio of polar vs.dispersive surface energy varies for the different plastic materials,both surface energy values are taken into account.For the demoulding forces measured in the first case Ž.Table 1,it could be seen that a CrNcoating,espe-cially,could offer good demoulding behaviour.When Ž.we compare Fig.3the surface energy values of DESMOPAN with the values for the mould surfaces Ž.ᎏSTAVAX s uncoated ,CrN and TiN ᎏthen it can be seen,for both total surface energy as polar surface energy,that the measured values for DESMO-Ž2.Fig.3.Total surface energies mJ r m of the different coatings and plastic materials.()M.Van Stappen et al.r Surface and Coatings Technology142᎐1442001143᎐145145Ž2.Fig.4.Polar surface energies mJ r m of the different coatings and plastic materials.PAN are lower compared to the mould surface values. This means that there is no correlation between the demoulding forces measured and the surface energy values.It seems,however,that a CrN surface has the lowest surface energy compared to a TiN coated sur-face and an uncoated surface.When one looks to the total surface energy values Ž.Fig.3,one can see that SANTOPRENE has the lowest value and HYTREL the highest.If our hypothesis was correct from the beginning,we should conclude that the demoulding force for HYTREL should be small and should be large for SANTOPRENE.One can see from Fig.2that this is not the case.When one looks at the polar surface energy values Ž.Fig.4,the three plastic materials have a lower value than the mould surface and SANTOPRENE and EVOPRENE have a lower value than HYTREL. Even when other surface energy criteria are used, e.g.the lower the energy of the mould surface theŽ.lower the demoulding force3,even then no correla-tion can be found.It can be seen that a TiN coating always increases the surface energy and,on the other hand,good de-moulding is sometimes seen, e.g.for HYTREL and DESMOPAN,and sometimes bad demoulding results, e.g.for EVOPRENE.Hence,we can conclude that,based on the surface energy values measured,no correlation could be found within the demoulding forces.Obviously,other parameters,such as roughness and injection tempera-ture,also play an important role in explaining the demoulding behaviour.In order to continue the research work to explain the demoulding behaviour,we will focus onfive industrial demonstrations and try to incorporate all relevant parameters:coating properties,plastic material proper-ties and injection parameters.4.ConclusionsNo correlation could be found between the demould-ing behaviour of plastics vs.coated moulds and the measured surface energy values.Other parameters must also influence this demould-ing behaviour.Further research will focus on other parameters like coating properties,plastic properties and injection parameters.Referencesw x1Annonymous,Big savings made with coated injection mouldingŽ.tool,Precision Toolmaker61998,138w x2O.Kayser,PVD-Beschichtungen schutzen werkzeug und¨Ž.schmelze,Kunststoffe7199598.w x3M.Grischke,Hartstoffschichten mit niedriger Klebneigung,JOT Ž.1199615.。

模具毕业设计外文翻译(英文+译文)
Injection MoldingThe basic concept of injection molding revolves around the ability of a thermoplastic material to be softened by heat and to harden when cooled .In most operations ,granular material (the plastic resin) is fed into one end of the cylinder (usually through a feeding device known as a hopper ),heated, and softened(plasticized or plasticized),forced out the other end of the cylinder, while it is still in the form of a melt, through a nozzle into a relatively cool mold held closed under pressure.Here,the melt cools and hardens until fully set-up. The mold is then opened, the piece ejected, and the sequence repeated.Thus, the significant elements of an injection molding machine become: 1) the way in which the melt is plasticized (softened) and forced into the mold (called the injection unit);2) the system for opening the mold and closing it under pressure (called the clamping unit);3) the type of mold used;4) the machine controls.The part of an injection-molding machine, which converts a plastic material from a sold phase to homogeneous seni-liguid phase by raising its temperature .This unit maintains the material at a present temperature and force it through the injection unit nozzle into a mold .The plunger is a combination of the injection and plasticizing device in which a heating chamber is mounted between the plunger and mold. This chamber heats the plastic material by conduction .The plunger, on each stroke; pushes unbelted plastic material into the chamber, which in turn forces plastic melt at the front of the chamber out through the nozzleThe part of an injection molding machine in which the mold is mounted, and which provides the motion and force to open and close the mold and to hold the mold close with force during injection .This unit can also provide other features necessary for the effective functioning of the molding operation .Movingplate is the member of the clamping unit, which is moved toward a stationary member. the moving section of the mold is bolted to this moving plate .This member usually includes the ejector holes and mold mounting pattern of blot holes or “T” slots .Stationary plate is the fixed member of the clamping unit on which the stationary section of the mold is bolted .This member usually includes a mold-mounting pattern of boles or “T” slots. Tie rods are member of the clamping force actuating mechanism that serve as the tension member of the clamp when it is holding the mold closed. They also serve as a gutted member for the movable plate .Ejector is a provision in the clamping unit that actuates a mechanism within the mold to eject the molded part(s) from the mold .The ejection actuating force may be applied hydraulically or pneumatically by a cylinder(s) attached to the moving plate, or mechanically by the opening stroke of the moving plate.Methods of melting and injecting the plastic differ from one machine to another and are constantly being implored .conventional machines use a cylinder and piston to do both jobs .This method simplifies machine construction but makes control of injection temperatures and pressures an inherently difficult problem .Other machines use a plasticizing extruder to melt the plastic and piston to inject it while some hare been designed to use a screw for both jobs :Nowadays, sixty percent of the machines use a reciprocating screw,35% a plunger (concentrated in the smaller machine size),and 5%a screw pot.Many of the problems connected with in ejection molding arise because the densities of polymers change so markedly with temperature and pressure. thigh temperatures, the density of a polymer is considerably cower than at room temperature, provided the pressure is the same.Therefore,if molds were filled at atmospheric pressure, “shrinkage” would make the molding deviate form the shape of the mold.To compensate for this poor effect, molds are filled at high pressure. The pressure compresses the polymer and allows more materials to flow into the mold, shrinkage is reduced and better quality moldings are produced.Cludes a mold-mounting pattern of bolt holes or “T” slots. Tie rods are members of the clamping force actuating mechanism that serve as the tension members of clamp when it is holding the mold closed. Ejector is a provision in the calming unit that actuates a mechanism within the mold to eject the molded part(s) form the mold. The ejection actuating force may be applied hydraulically or pneumatically by a cylinder(s) attached to the moving plate, or mechanically by the opening stroke of the moving plate.The function of a mold is twofold: imparting the desired shape to the plasticized polymer and cooling the injection molded part. It is basically made up of two sets of components: the cavities and cores and the base in which the cavities and cores are mounted. The mold ,which contains one or more cavities, consists of two basic parts :(1) a stationary molds half one the side where the plastic is injected,(2)Moving half on the closing or ejector side of the machine. The separation between the two mold halves is called the parting line. In some cases the cavity is partly in the stationary and partly in the moving section. The size and weight of the molded parts limit the number of cavities in the mold and also determine the machinery capacity required. The mold components and their functions are as following:(1)Mold Base-Hold cavity (cavities) in fixed, correctposition relative to machine nozzle.(2)Guide Pins-Maintain Proper alignment of entry into moldinterior.(3)Spree Bushing (spree)-Provide means of entry into moldinterior.(4)Runners-Conroy molten plastic from spree to cavities.(5)Gates-Control flow into cavities.(6)Cavity (female) and Force (male)-Control the size,shape and surface of mold article.(7)Water Channels-Control the temperature of mold surfacesto chill plastic to rigid state.(8)Side (actuated by came, gears or hydrauliccylinders)-Form side holes, slots, undercuts and threaded sections.(9)Vent-Allow the escape of trapped air and gas.(10)Ejector Mechanism (pins, blades, stripper plate)-Ejectrigid molded article form cavity or force.(11)Ejector Return Pins-Return ejector pins to retractedposition as mold closes for next cycle.The distance between the outer cavities and the primary spree must not be so long that the molten plastic loses too much heat in the runner to fill the outer cavities properly. The cavities should be so arranged around the primary spree that each receives its full and equal share of the total pressure available, through its own runner system (or the so-called balanced runner system).The requires the shortest possible distance between cavities and primary sprue, equal runner and gate dimension, and uniform culling.注射成型注射成型的基本概念是使热塑性材料在受热时熔融，冷却时硬化，在大部分加工中，粒状材料（即塑料树脂）从料筒的一端（通常通过一个叫做“料斗”的进料装置）送进，受热并熔融（即塑化或增塑），然后当材料还是溶体时，通过一个喷嘴从料筒的另一端挤到一个相对较冷的压和封闭的模子里。

本科毕业设计(论文)外文翻译（附外文原文）学院：机械与控制工程学院课题名称：复杂阶梯形圆筒件拉深有限元分析专业(方向)：机械设计制造及其自动化（模具设计与制造）班级：学生：指导教师：日期：拉伸模设计中拉伸壁起皱的分析摘要本文研究带有斜度的方形盒和带有阶梯的方形盒的拉深中发生的起皱现象。
这两种类型的起皱现象有一个共同的特征：全都发生在相对无支撑、无压边的拉深壁处。
在带有斜度的方形盒的拉深中，常受到工序参数的影响，例如：模具的间隙值和压边力等，所以常用有限元模拟的方法来研究分析起皱的发生。
模拟的结果表明模具的间隙值越大，起皱现象就越严重，而且增加压边力也不能抑制和消除起皱现象的发生。
在带有阶梯的方形盒拉深的起皱现象分析中，常通过实际生产中一种近似的几何结构来研究、试验。
当凸模与阶梯边缘之间的金属板料在拉深时分布并不均衡，就会在侧壁发生起皱现象。
为了消除起皱现象的发生，一个最优的模具设计常采用有限元的方法进行分析。
模拟的结果和起皱试验论证了有限元分析的准确性，并且表明了在拉深模具设计中使用有限元方法分析的优越性。
关键词:侧壁起皱；拉深模；带有阶梯的方形盒；带有斜度的方形盒1 引言起皱是金属板料成形中常见的失效形式之一。
由于功能和视觉效果的原因，起皱通常是不能为零件制品所能接受的。
在金属板料成形加工中通常存在三种类型的起皱现象：法兰起皱；侧壁起皱和由于残余压应力在未变形区产生的弹性变形。
在冲压复杂形状的时候，拉深壁起皱就是在模具型腔中形成的褶皱。
由于金属板料在拉深壁区域内相对无支撑，因此，消除拉深壁起皱比抑制法兰起皱要难得多。
我们知道在不被支撑的拉深壁区域中材料的外力拉深可以防止起皱，这可以在实践中通过增加压边力而实现，但是运用过大的拉深力会引起破裂失效。
因此，压边力必须控制在一定的范围内，一方面可以抑制起皱，另一方面也可以防止破裂失效。
合适的压边力范围是很难确定的，因为起皱在拉深零件的中心区域以一个复杂的形状形成，甚至根本不存在一个合适的压边力范围。

冲压--是在室温下，利用安装在压力机上的模具对材料施加压力，使其产生分离或塑性变形，从而获得所需零件的一种压力加工方法。
冲压模具的形式很多，一般可按以下几个主要特征分类：1•根据工艺性质分类(1)冲裁模沿封闭或敞开的轮廓线使材料产生分离的模具。
如落料模、冲孔模、切断模、切口模、切边模、剖切模等。
(2)弯曲模使板料毛坯或其他坯料沿着直线(弯曲线)产生弯曲变形，从而获得一定角度和形状的工件的模具。
(3)拉深模是把板料毛坯制成开口空心件，或使空心件进一步改变形状和尺寸的模具。
(4)成形模是将毛坯或半成品工件按图凸、凹模的形状直接复制成形，而材料本身仅产生局部塑性变形的模具。
如胀形模、缩口模、扩口模、起伏成形模、翻边模、整形模等。
2•根据工序组合程度分类(1)单工序模在压力机的一次行程中，只完成一道冲压工序的模具。
(2)复合模只有一个工位，在压力机的一次行程中，在同一工位上同时完成两道或两道以上冲压工序的模具。
(3)级进模(也称连续模) 在毛坯的送进方向上，具有两个或更多的工位，在压力机的一次行程中，在不同的工位上逐次完成两道或两道以上冲压工序的模具。
冲冷冲模全称为冷冲压模具。
冷冲压模具是一种应用于模具行业冷冲压模具及其配件所需高性能结构陶瓷材料的制备方法，高性能陶瓷模具及其配件材料由氧化锆、氧化钇粉中加铝、错元素构成，制备工艺是将氧化锆溶液、氧化钇溶液、氧化错溶液、氧化铝溶液按一定比例混合配成母液，滴入碳酸氢铵，采用共沉淀方法合成模具及其配件陶瓷材料所需的原材料，反应生成的沉淀经滤水、干燥，煅烧得到高性能陶瓷模具及其配件材料超微粉，再经过成型、烧结、精加工，便得到高性能陶瓷模具及其配件材料。
本发明的优点是本发明制成的冷冲压模具及其配件使用寿命长，在冲压过程中未出现模具及其配件与冲压件产生粘结现象，冲压件表面光滑、无毛刺，完全可以替代传统高速钢、钨钢材料。
冷冲模具主要零件冷冲模具是冲压加工的主要工艺装备，冲压制件就是靠上、下模具的相对运动来完成的。
加工时由于上、下模具之间不断地分合，如果操作工人的手指不断进入或停留在模具闭合区，便会对其人身安全带来严重威胁。
1（一）模具的主要零件、作用及安全要求1．工作零件凸凹模是直接使坯料成形的工作零件，因此，它是模具上的关键零件。
凸凹模不但精密而且复杂，它应满足如下要求：（1）应有足够的强度，不能在冲压过程中断裂或破坏．（2）对其材料及热处理应有适当要求，防止硬度太高而脆裂。
2．定位零件定位零件是确定坯件安装位置的零件，有定位销（板）、挡料销（板）、导正销、导料板、定距侧刀、侧压器等。
设计定位零件时应考虑操作方便，不应有过定位，位置要便于观察，最好采用前推定位、外廓定位和导正销定位等。
3．压料、卸料及出料零件压料零件有压边圈、压料板等。
压边圈可对拉延坯料加压边力，从而防止坯料在切向压力的作用下拱起而形成皱褶。
压料板的作用是防止坯料移动和弹跳。
顶出器、卸料板的作用是便于出件和清理废料。
它们由弹簧、橡胶和设备上的气垫推杆支撑，可上下运动，顶出件设计时应具有足够的顶出力，运动要有限位。
卸料板应尽量缩小闭合区域或在操作位置上铣出空手槽。
暴露的卸料板的四周应设有防护板，防止手指伸入或异物进入，外露表面棱角应倒钝。
4．导向零件导柱和导套是应用最广泛的一种导向零件。
其作用是保证凸凹模在冲压工作时有精确的配合间隙。
因此，导柱、导套的间隙应小于冲裁间隙。
导柱设在下模座，要保证在冲程下死点时，导柱的上端面在上模板顶面以上最少 5 至10 毫米。
导柱应安排在远离模块和压料板的部位，使操作者的手臂不用越过导柱送取料。
5．支承及夹持零件它包括上下模板、模柄、凸凹模固定板、垫板、限位器等。
上下模板是冷冲模具的基础零件，其他各种零件都分别安装固定在上面。
模板的平面尺寸，尤其是前后方向应与制件相适应，过大或过小均不利于操作。
有些模具（落料、冲孔类模具）为了出件方便，需在模架下设垫板。
这时垫板最好与模板之间用螺钉连接在一起，两垫板的厚度应绝对相等。
垫板的间距以能出件为准，不要太大，以免模板断裂。
6．紧固零件它包括螺钉、螺母、弹簧、柱销、垫圈等，一般都采用标准件。
冷冲模具的标准件用量较多，设计选用时应保证紧固和弹性顶出的需要，避免紧固件暴露在表面操作位置上，防止碰伤人手和妨碍操作。
冷冲模具的发展改革开放以来，随着国民经济的高速发展，市场对冷冲模具的需求量不断增长。
近年来，冷冲模具工业一直以15%左右的增长速度快速发展，冷冲模具工业企业的所有制成分也发生了巨大变化，除了国有专业模具厂外，集体、合资、独资和私营也得到了快速发展。
随着与国际接轨的脚步不断加快，市场竞争的日益加剧，人们已经越来越认识到产品质量、成本和新产品的开发能力的重要性。
而冷冲模具制造是整个链条中最基础的要素之一，冷冲模具制造技术现已成为衡量一个国家制造业水平高低的重要标志，并在很大程度上决定企业的生存空间。
近年许多冷冲模具企业加大了用于技术进步的投资力度，将技术进步视为企业发展的重要动力。
一些国内模具企业已普及了二维CAD并陆续开始使用UGProEngineer、l-DEAS、Euclid-IS 等国际通用软件，个别厂家还引进了Moldflow、C-Flow、DYNAFORMDptris 和MAGMASO 等TCAE软件，并成功应用于冲压模的设计中。
以汽车覆盖件模具为代表的大型冲压模具的制造技术已取得很大进步，东风汽车公司模具厂、一汽模具中心等模具厂家已能生产部分轿车覆盖件模具。
此外，许多研究机构和大专院校开展模具技术的研究和开发。
经过多年的努力，在模具CADCAECAM术方面取得了显著进步；在提高模具质量和缩短模具设计制造周期等方面做出了贡献。
虽然中国冷冲模具工业在过去十多年中取得了令人瞩目的发展，但许多方面与工业发达国家相比仍有较大的差距。
例如，精密加工设备在冷冲模具加工设备中的比重比较低；CADCAECAM术的普及率不高；许多先进的模具技术应用不够广泛等等，致使相当一部分大型、精密、复杂和长寿命冷冲模具依赖进口。
随着科学技术的不断进步，现代工业产品的生产日益复杂与多样化，产品性能和质量也在不断提高，因而对冷冲压技术提出了更高的要求•为了使冷冲压技术能适应各工业部门的需要，冷冲压技术自身也在不断革新和发展•冷冲压技术的发展思路就是尽可能地完善和扩充冷冲压工艺的优点，克服其缺点•在冷冲压技术的发展过程中，应注意以下几方面：(1)冷冲压技术的发展过程中应正确地确定工艺参数及冷冲模具工作部分的形状与尺寸，提高冲压件的质量、缩短新产品试制周期，应在加强冲压成形理论研究的基础上，使冲压成形理论达到能对生产实际起指导作用，逐步建立起一套密切结合生产实际的先进的工艺分析计算方法•国外已开始采用弹塑性有限元法对汽车覆盖零件的成形过程进行应力应变分析和计算机模拟，以预测某一工艺方案对零件成形的可能性和可能出现的问题。
(2)加快产品更新换代，克服模具设计周期长的缺点•应大力开展模具计算机辅助设计和制造(CADCAM技术的研究•在我国,目前要特别注意加强多工位级进模CADCA技术的研究。
(3)满足大量生产需要以及减轻劳动强度.应加强冷冲压生产的机械化和自动化研究，使一般中、小件能在高速压力机上采用多工位级进模生产，达到生产高度自动化，进一步提高冲压的生产率。
(4)扩大冷冲压生产的运用范围.使冷冲压既适合大量生产，也适合小批量生产；既能生产一般精度的产品，也能生产精密零件•应注意开发如精密冲裁(特别是厚料精冲)、高能成形、软模成形、施压和超塑性加工等新成形工艺，还要推广简易模(软模和低熔点合金模)、通用组合模、数控冲床等设备的运用。
此外,对冲压板料性能的改进，模具新材料、模具新加工方法的开发也应进一步加强。
冷冲模具使用寿命的影响及对策冷冲模具的使用寿命是以冲制出的工件数量来计算的。
影响冷冲模寿命的因素很多。
主要有模具结构设计、制造模具所用凸模和凹模的材料、模具的热处理质量与表面强化、冲模零件的制造精度和冷冲压材料的选取。
除此之外，还有冲模的安装、调整、使用以及维修等。
1.模具设计对寿命的影响(1)排样设计的影响排样方法与搭边值对模具寿命的影响很大，过小的搭边值，往往3是造成模具急剧磨损和凸、凹模啃伤的重要原因。
从节约材料出发，搭边值愈小愈好，但搭边值小于一定数值后，对模具寿命和剪切表面质量不利。
在冲裁中有可能被拉人模具问隙中，使零件产生毛刺，甚至损坏模具刃口，降低模具寿命。
因此，在考虑提高材料利用率的同时，必须根据零件产量、质量和寿命，确定排样方法和搭边值。
(2)凹模结构的影响对容易产生应力集中而开裂的凹模结构，可以采用组合结构或镶拼结构，以及预应力结构，从而提高模具使用寿命。
(3)间隙的影响当间隙过小时，压缩挤压利害，摩擦力增大，磨损增大，侧面的磨损加剧，冲裁后卸料和推件时，材料与凸、凹模之间的摩擦还将造成刃口侧面的磨损比端面的磨大大，同时也容易造成凸、凹模温度很高，把金属碎屑吸附在刃口侧面，形成金属瘤，使凸、凹模出现崩刃或胀裂现象。
因此，过小的间隙对模具寿命极为不利。
间隙太大，会增加凸模与凹模端面边缘的集中应力，致使压应力急剧增加，于是刃口边很快屈服变形而失去棱角。
因此又增加了冲裁力，进而使刃口边更快磨损，降低模具寿命。
但为了减小凸、凹模的磨损，延长模具使用寿命，在保证冲裁件质量的前提下，设计时适当采用较大间隙是十分必要的。
(4)模具导向结构对寿命的影响可靠的导向对于减小工作零件的磨损，避免凸、凹模啃伤是非常有效的。
特别对无问隙或小问隙冲裁模、复合模和多工位级进模更为重要。
为提高模具寿命，必须根据工序和零件精度要求，正确选择导向形式和导向精度，所选择导向精度应高于凸、凹模的配合精度。
(5)冷冲压材料选取的影响冷冲压材料应满足制件的设计要求和冲压工艺要求，否则容易损伤模具，降低模具使用寿命。
冷冲压材料表面质量不好，冲压时制件易破裂，也易擦伤模具。
冷冲压材料塑性不好，变形量小，冲压时制件易破裂，也易擦伤模具。
另外，材料的厚度公差应符合国家标准。
因为一副冲模适用于一定材料的厚度，成形、弯曲、翻边、引伸模具的凸、凹模结构间隙是直接根据材料厚度来确定的。
所以材料厚度不均匀，会导致废品产生和模具损坏。
2．模具材料对模具寿命的影响模具材料对模具寿命的影响是模具材料性质、化学成分、组织结构、硬度和冶金质量等的综合反映。
其中，材料性质和热处理质量影响最为明显。
模具材料性质对模具寿命的影响是很大的。
如将同一种工件，使用不同的模具材料做弯曲试验，试验结果：用9Mn2V 材料，其寿命为5万次；用Crl2MoV渗氮，其寿命可达40万次。
