电器支架注塑模具设计

摘要:通模具按制造的产品分类,可以分为塑料模具(又分为注塑模具、铸压模

具和吹塑模具)、冲压模具、铸造模具、橡胶模具和玻璃模具等。其中,尤以注

塑模具和冲压模具用途广、技术成熟、占据的比重大。过对电器支架工艺的正确

分析,设计了一副一模一腔的塑料模具。详细的叙述了模具成型零件包括型腔、

型芯等设计,重要零件的工艺参数的选择与计算,浇注系统、冷却系统以及其它

结构的设计过程,模架的选择原则。并利用 PRO/E 中的 Plastic Advisor塑料顾

问对设计完成的塑料模具进行了塑料流动分析。 关键词: 电器支架 注塑模具 PRO/ECAD Design?of?Plastic?Injection?Mould?for? Electric?appliance?support? Abstract:?
