气体发生器壳体模流分析及模具结构设计

摘要

In order to improve the design level of injection mold for gas generator shell,the CAE software was used to simulate the flow of the gas generator shell,and the results of mold flow analysis were used to guide the gating system and structural de-sign of the mold.Through the optimization design,many kinds of core pulling mechanism of injection mould coexisted,and the application range of injection mould was improved.%为了提高气体发生器壳体注射模具设计水平,利用计算机辅助工程(CAE)软件对气体发生器壳体进行模流分析,采用模流分析结果指导模具浇注系统及结构设计.经过优化设计实现注射模具多种抽芯机构共存,提高了注射模具的应用范围.
