1.为预防粘前模，外侧面斜度由0.5o均改为1o To avoid sticking to cavity, change outside surface draft from 0.5o to 1o 3.红色区域可能出现缩水，是否接受？

There may be sink mark on red surface, could you accept that?

10.紫色面做5?加胶插穿斜度(加胶0.1mm MAX) Add plastic on purple surface with 5 degree shut-off draft (add 0.1mm max plastic) Zebra 20Jan2016: this surface mates to another flat surface; adding material will cause issues with assembling part P1082228 into printer 这种表面配合到另一平面上; 添加材料会导致零件P1082228装配到打印机产生问题 11.PL 插穿段差CA V 凹0.15mm 以下（对侧同） Step exist on PL shut-off surface, suggest that core concave 0.15mm max ( same for opposite side) 13.后模镶件印凹0.1mm 以下 Core insert mark concave 0.1mm max 16.顶针及方顶印凹0.1mm 以下 EP and square EP mark concave 0.1 max is there any concern about the thin material (filling and ejection)?薄胶处有无问题？ 17.材料及模穴号（1,2）凸0.2mm Material and Cav no. convex 0.2mm

扣易粘前模，需如图增加前模镶件和弹块，PL 如图更新。

Hook easily stick to cav., need to add insert and slider as picture. PL is updated

as picture shows. 孔处PL 段差COR 凹0.1mm 以下 There is step at PL of hole, concave 0.1mm max. Could 12.图示柱子根部做火山口，改善现状部品缩水。

Make break sharp in the area as shown above to combat sink marks

16.前模互换镶件（3款互换），与现状部品完全一致

Interchangeable cavity inserts (3 ones), Same feature as those in the old-tool time 19.针阀式热咀进浇（?5），残留不超出凹位。

Valve gate(?5), vestige to be flush to be in line with the concave Min()

1>Causes of the cracks on the tool：

a>钢料太硬造成钢料太脆，从而造成钢料易裂，建议用软钢料开新

模.For steel performance, the harder, the more fractural. Based on this reason, a relatively low h ard steel is suggested to be used for the new tool.

b>模仁两侧边的钢料厚度不够，现实际为41mm，而深度有59mm，建议两侧钢料壁厚加到60mm.

The nominal thickness of the core side steel is 41mm with the depth of 59mm.

The suggested thickness is 60mm.

c>缩水率不合理，物性表上要求的缩水率为0.5-0.7%，现实际模具缩水率为0.5%，造成整体模具数偏下限，从而造成尺寸下限或偏小，而此产品寸法要求严，要大压力去成型调整尺寸。

The data-shrinkage rate is 0.5-0.7%, well the actual shrinkage rate is 0.5%. With the presence of

the actual rate, the overall dimensions tend to be below the nominal ones. To combat these complications, a high injection pressure is needed.

d>多次设变也会造成模具寿命的折损。

The multi-occurance of design change shortens the life cycle of the tool.

2>进胶口热流道方式确认：Hot runner system:

e>如进胶口为针阀式的热流道，则浇口处会有气纹不良，需客人确认限度。

Valve one brings forth splays.

f>如进胶口为开放式的热流道，则浇口处会有殘胶需要加工，故需要增加一个人工加工平水口残胶open one will have a vestige needed to be trimmed off.

蓝色面做5?加胶插穿斜度（加胶0.1mm）

Add plastic (0.1mm) for blue area with shut-off draft of 5 degree

1.图示红色面做3?减胶插穿斜度，

改善现有产品易出现披锋的问题。

The red area to be tapered 3through thinning to combat

Flash.

6.行位镶针距离骨太近，导致后模钢料只有0.6mm，

建议红色面减胶1mm，以增强钢料，避免开裂。

For better steel strength ,the red area to be thinned 1mm

(the cam steel pin is too close to the boss with the result

That the core steel in this area leaves only 0.6mm) thickness.

6.此后是针阀单点进浇口及2点进浇口的模流分析。

The mold flow analysis with one gate and two gates by using valve gate

建议做一个热咀的进胶口，原因如下：propose one gate is based on:

1>两个热咀的距离太近，造成两个热流道靠得近，从而造成热流道制作困难。Geographically,

two gates are two close, which entails the two respective manifolds too close. To design the two manifolds is way too difficult.

2>做两个热流道后前模芯就会挖空的更多，从而造成前模芯的强度变弱很多

With two manifolds, the cavity to be cored out too much, as a result the strength of it weakens.

Thin steel risk here-

To combat this complication, a removal of R in red should be performed

为防止粘前模，建议孔修改如右图示

Sticking in the cavity here-

To prevent this process issue, please use the feature changes stated in the right

figure

1.红色减胶（取数1X2）

方案：后模加钢，新增镶件对应（盲镶）

1. Add material at red coded area (2 cavities)

Method：Thicken steel at the new core insert (blind insert)

新增后模镶件，印凹0.1mm以下

Application of a new insert at the core,

recess to be 0.1mm Max below the surface. 17.牛角进浇（?1.4），残留不超出凹坑。浇口对面容易出现色差，请确认。

17.Submarine gate（?1.4）

Application of gate well

Vestige to be within the gate well

Slight color difference near the gate area

21.增加蓝色骨，优化斜顶PL，(In blue) to better lifter line, Thus to

remove the thin steel issue

6. Valve gate （?1.5）

Application of gate well to combat the vestige issue-vestige to be within the gate well

Slight color difference will occur near the gate area

6.单点针阀热咀进浇（?1.5），残留不超出弧面。

此种进浇对应表现会出现色差，请确认。

3.这些红色柱子及骨位会使产品外观及侧壁缩水，

建议红色柱子根部厚度做1.4并增加火山口；

红色骨改为底部1.2mm，顶部0.9mm，

3. Feature changes in the red area-

Boss base thickness to be 1.4mm as well an application of cut at the boss base (details pls see the below) Rib base thickness to be 1.2mm and rib top thickness to be 0.9mm (details pls see the below)

产品尖角处无法填充，R0.1如图改为R0.3，请确认。

Sharp area could not be filled

To combat this missing feature after moulding-

To use R0.3 to replace R0.1 as illustrated in Figure2
