设计简介
本论文根据工程实际的需要完成带二次顶出机构的注射模具设计。在设计中采用聚乙烯塑料注射而成型，成型方式为一模两腔，该论文具体分析了产品的工艺性，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，并进行了一些必要的尺寸计算和强度的校核。该论文还对分型面、浇注系统和脱模机构进行了分析设计，完成了模具工程图设计，最后进行了主要零件加工工艺设计，圆满完成了模具设计所要求的各项工作。
通过设计，综合应用了大学期间的多数基础和专业知识，加深所学知识体系，熟悉了工程应用设计。
关键词 注射模 成型 工艺性 设计
In this paper, the actual needs in accordance with the project completed with the second top of the body design of injection molds. Polyethylene used in the design of plastic injection molding, for forming a two-cavity mold, the paper analyzes the specific products of the process, identified by the use of plastics and the process parameters of the molding equipment used to determine the overall production of the mold program, analysis and address the overall structure of the mold and the work of some of the specific structure and a number of the necessary size and strength check calculation. The paper also surface, gating system and the release of the analysis and design agencies to complete the mold design engineering drawings, and finally to the main processing parts design, mold design successfully completed all the work required.
Through the design, the comprehensive application of the majority of the college foundation and expertise to enhance the knowledge system, familiar with the design of engineering applications.
