盖注塑注塑成型工艺及模的设计
摘要：本设计题目为盖注塑模设计，体现了盒盖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。
本塑件体积较小，无需侧抽机构，因而模具设计也较简单。本模具才有顶杆推出机构脱模，结构合理可靠。

the design of Cover injection mold
Abstract：The topic of this design is the shell cover stamps forming handicraft and design for die.The requirement，content and direction of the design of the stamps forming plate parts are embodied on this stamping die design. The designer’s foundation knowledge of the stamping die design is reinforced and is able to design more complex stamping die through the design.
This design the elementary knowledge which designs using the stamping formation craft and the die, first has analyzed the work piece formed craft and the die forming structure to the workpiece quality influence. Introduced the shell cover filling piece stamping die design when must pay attention to the main point, through carries on the craft analysis to the workpiece, may determine the workpiece the formed processing uses set of superposable dies. Embarks from the control workpiece size precision, counter shell cover filling piece stamping die each main dimension has carried on the theoretical calculation, by determined each work components the size, designs from the die to the spare part processing craft as well as the assembly craft and so on carries on the detailed elaboration, and carries on each important components using CAD the design.
