产品检讨
1. 和滑块干涉的倒勾请加料填平至滑块可以顺利滑动
(The undercut area where interfere with slide block need to be filled material to help the
slider can move smoothly.)
2. 加肉太多
(The thickness is added too thick.)
3. 加肉面积太大 (The thickening area is too wide.)
4. GATE位置移位 (Gate position is moved.)
5. 滑块拆的位置 (The split line of slide block or the area of slide.)
6. 此处有尖角，填充困难 (This area is hard to be filled due to the sharp feature.)
7. 此处钢材太薄，强度不足而且不容易冷却
(The strength of this area is too weak and isn’t easy to get cold due to the steel too thin.)
8. 圆柱特征要有一半圆不可以拆在滑块上，以免粘滑块造成拉白，拉断
(The semicircle of cylinder avoids designing on slide block lest it will be pulled apart or
cause drag mark)
9. 此处做斜销在作动时会削到成品肉厚
(The part will get damage if we make lifter in this area.)
10. 这个面是装配面，不能加料
(This is critical surface where is not allow to add material.)
11. 此处料位太厚，会有缩水，建议减料改善
(Owing to the shrinkage of the thickness that we suggest to reduce some wall thickness to
improve it.)
12. 此面是不是外观面，此处做滑块的话会有夹线，是否可以接受
(Please confirm whether it is critical surface or not. Please confirm whether it is
acceptable to has Slide split line if we have slide in this area. )
13. 此处有倒勾，能否减料，使公母模靠破，不做滑块和斜销
(Please confirm whether we can reduce material to the area where have undercut as
indicated to have shut off on cavity side. No slide block and lifter to be made. )
14. 请尽快确认这种拆模方式和结构，否则会影响模期
(Please confirm the issues of Parting line, Gate position...Etc otherwise the lead-time will
be extended.)
15. 此面是否有特殊要求，能否有顶针印
(Please confirm whether it is a critical surface or not and can we have E.J. pin mark on it.)
16. P.L面开在此处，模具上会有尖角和刀口，对模具寿命有影响
(There are sharp edges if set the parting line at here, It will reduce the tool life)
17. 加大拔模角，以便脱模顺利
(We would suggest to enlarging draft to help tool released.)
18. GATE做在此处的话有两个缺点：1.盖子打开时可以看到GATE的修剪部位; 2.两个斜销
在同一侧，顶出也不是很平衡.
(Two imperfect points if the gate is to be designed in this area as below:
a). Easy to see the gate mark when you open the cap.
b). Unbalance of ejector when two lifters are at the same side)
19. GATE做在此处的话.盖子打开后看不到GATE的修剪部位
(The gate mark is not visual if the gate position is design like it.)
20. 如果GATE一定要做在你们指定的位置的话，那还不如做在这一侧，这样的话还可 以减
小这个位置的缩水
(If you insist that the gate position have to be as original design then we would further
recommend to have it to the area where indicate as it can avoid shrink problem in this
area.)
21. 在此处GATE做潜顶针的话，背后的外观面会有冲料痕，而且成品又是黑色的，会最明
显
(If the gate type has to be design as sub. gate then the back surface of part will have flow
mark with serious due to black colour.)
22. P.L开在此处不合理，模具加工困难，P.L应改为和图示的一样
(This area is not suitable to have Parting line as the tool will become more complicate
therefore we recommend to have Parting line as indicated.)
23. 此成品粘母模的机会很大，能否在公模加倒勾，拉料顶针或者公模保留E.D.M纹，开
模时使成品留在公模一侧
(It is possible sticking on cavity, therefore, please confirm whether it can make undercuts,
snatch pins or leave coarse E.D.M. on core to snatch part on)
24. 此处料厚段差很大，成品表面会有应力痕，是否接受
(Please confirm whether it is acceptable to has stress line on surface, it is cause to the
thickness isn’t equally.)
25. 请注明何处为外观面，能否提供2D图和注意事项
(Please advise where is the critical surface. Please also provide us 2D drawing with
critical dimensions. )
26. 红色所示处是有问题的地方，请特别注意
(Please pay more attention to the area where highlighted as red colour as this area have
problem.)
27. 成品设计此处有问题，建议如下图所示修改
(We would suggest to have part design as attached as the current design have problem.)
28. 此处改为一个球形的凹槽 (We would suggest to modify it as a globe recess.)
29. 圆柱特征要有一半不可以拆在滑块里，以防拉断 (this issue same as no.8)
30. 此处大滑块上走小滑块，小滑块要先退，大滑块要做延迟
(The inside small slide block will recede first and the parent slide block have to postpone
sliding.)
31. 滑块要用液压油缸抽芯以保证开合模顺序
(The slide pins will use oil cylinder to assure the process in proper order.)
32. 这个面有装配，加料的话装配时会顶住，如图所示
(This surface can not add material where will intervene between two parts as it is
assembly. Please see the sketch as attached. )
33. 可降低斜销面，增加成品些许肉厚来做变化
(To descend the surface of lifter in order to thicken the part.)
34. 一半做斜销，一半做自然 (Half side with Lifter and half side with solid / nature.)
35. 此处两个柱子重迭，有倒勾，不能做自然，要做SLIDE
(These two bosses are overlapping with undercut therefore it can not be made as solid.
We suggest to making it as slide block.)
36. 此处强迫顶出 (This area need to be as force ejection.)
