设计简介
本论文根据生产实际的需要完成复点机密封盖的塑料注射模具设计。由于塑料模具零件加工方法、加工工艺及装配方法都是不同的，所以在选择侧抽芯类型时需要谨慎。根据所设计的产品的具体结构进行分析，该模具采用侧抽芯机构。在设计中采用聚丙烯塑料注射而成，成型方式为一模两腔。本论文确定了所采用塑料的工艺参数和所采用的成型设备，确定了模具制作的总体方案，分析并解决了模具的总体结构和各工作部分的具体结构，并进行了必要的尺寸计算。对分型面、浇注系统等进行了分析设计，完成了模具工程图设计，最后用Pro/E对模具进行了三维的总装。使制作出来的产品的质量得到保证。

Abstract
In this paper, the bill counter closures plastic injection mould with side core-pulling mechanism is designed basing on practical needs. Processing methold, processing technology and assembling metholds of plastic mould parts are different ,so we need caution while choosing side core-pulling type. Side core-pulling mechanism is used according to specific structure of the products analyze. In this design, the plastic is injected and formed with polypropylene, and there are two cavitives in one mould. This paper include the determination of the technological parametre, formation equipment type, mould manufacturing overall concept, overall structure and the detailed structure of each working parts, essential size calculations, profile and gating systerm analysis design. ProEngineer is used on 3D assembling after mould graphics design finshed, to make sure the good quality of the products.
Keywords Inject mould Side core-pulling mechanism Polypropylene Two cavities in one mould
