塑胶模具DFM翻译参考

1.图示红色面做3ﾟ减胶插穿斜度，

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-
