膜片夹片注塑模设计
摘要
本设计题目为膜片夹片注塑模设计，体现了侧抽芯类塑料零件的设计要求、内容及方向，有一定的设计意义。通过对该零件模具的设计，进一步加强了设计者注塑模设计的基础知识，为设计更复杂的注塑模具做好了铺垫和吸取了更深刻的经验。
本设计运用塑料成型工艺及模具设计的基础知识，首先分析了塑件的成分及性能要求，为选取浇口的类型做好了准备；然后估算了塑件的体积，便于选取注塑机及确定型腔数量；最后分析了塑件的特征，确定模具的设计参数、设计要点及推出装置的选取。
本塑件的上端都有凸台，且塑件比较小，所以采用斜导柱侧抽芯机构，与侧滑块配合，能够顺利的完成侧向抽芯分型，模具结构简单，工作效率较高。由于需要侧向抽芯，故采用推杆脱模机构，这种机构脱模可靠，设计方便且在模具中占用空间较小，非常适合在本副模具中使用。

Diaphragm Design of Injection Mold Clips
Abstract
The topic for the patch design injection mold Clip design, reflects the type of side core pulling plastic parts design, content and direction of the design of a certain significance. Through the design of the die parts to further enhance the design of injection mold designers the basic knowledge for the design of more complex injection molds and do a good job of paving the way to draw a more profound experience.
Through the foundation knowledge, firstly, the composion and the perfourmance of the part is analyzed to choose the type of the gat advantagely. Secondly, the volume of the part is estimated to choose the injection molding machine and to detemine the mould quantity conveniencely. Lastly the character of the part is analyzed to determine the mould design parameter and design point and choose the ejection assembly.
The top of the plastic parts have a boss, and the relatively small plastic parts, so the use of oblique derivative side column core-pulling mechanism with the side of the slider with the smooth completion of the lateral sub-type core-pulling, mold structure is simple and more efficient high. Core-pulling because of the need to side, so putt Demoulding adopt institutions that Demoulding reliable, convenient and design space in the mold of smaller, very suitable for the use of the die deputy.
