摘要

塑料在当今世界上无处不用，因此塑料模具有很大发展，特别是注

塑模。由此可知，研究注塑模具对了解塑料产品的生产过程和提高

产品质量有很大意义。本课题主要是针对瓶盖的模具设计,通过对塑

件进行工艺性分析和比较,最终设计出一副注塑模。该课题从产品结

构工艺性及具体模具结构出发，对模具的浇注系统、模具成型部分

的结构、顶出系统、冷却系统、注塑机的选择及有关参数的校核、

都有详细的设计，同时并简单的编制了模具的加工工艺。通过整个

设计过程表明该模具能够达到此塑件所要求的加工工艺。根据题目

设计的主要任务是茶杯盖注塑模具的设计。也就是设计一副注塑模

具来生产茶杯盖的塑件产品，以实现自动化提高产量。

通过本设计，可以对注塑模具有一个较深的认识，注意到设计中的

某些细节问题，了解模具结构及工作原理；通过对program的学习，可以建立较简单零件的零件库，从而有效的提高工作效率；通过画

装配图、零件图，进一步系统深化cad熟练程度，加深了对模具各

个零件的认识。

abstract

plastic is everywhere in the world today with , therefore has great development prospects of plastic , especially in injection molding ,so the study of plastic injection molds for understanding the production process and improve the quality of products

have great significance.

this topic mainly aims at bottle caps mold design, through to models to carry on the technological analysis and the comparison , this topic embarks from the product mix technology capability and the concrete mold structure , to

molds gating system, the mold formation parts structure, goes

against the system, the cooling system, injection molding machines choice and the related parameter examination, has the detailed design, simultaneously and simple establishment molds processing craft. through the entire design process indicated that this mold can achieve this to model the processing craft which an institute requests. is the teacup covers injection molds design according to the topic designs primary mission. is also designs an injection mold to produce the teacup to cover models a product, realizes the automation to raise the output

through the design, injection mold can have a deeper understanding of the design notes that some of the details to understand the structure and working principle of

mold.through learning program, you can create a simpler components parts store, and effective improve efficiency; through painting assembly drawing, part drawings, and further deepen the cad system proficiency, a better understanding of the various parts of mold.

key words: plastic mold, injection machine, mold cavity, pouring system
