1、毕业设计说明书一壳体模具设计与制造系(院):机械工程系专 业:模具设计与制造班 级:06124学 号:11姓 名:胡应鑫指导老师:成都电子机械高等专科学校2022年5月18日摘要塑料是一种新型工程材料,进展速度迅猛,塑料的加工和成型工艺也越来越得到重视,其中注射成型是最常用的塑料零件成型方法。生活用品的塑料模具占了很大比例。该课题的主要任务是设计一副壳体注塑模具来生产壳体塑件制品,以实现自动化生产提高产量。针对壳体的具体结构,该壳体注塑模设计制造的最大难点在于浇注系统和脱模机构。通过对点浇口、侧浇口、埋伏式浇口三种方案的比较,得出结论埋伏式浇口的结构形式最为合理。设计出的模具为埋伏式浇口单分型
2、面的结构形式。塑件整体尺寸较小,型腔较深壁厚较薄,在圆形外壁上有4个小孔,总体结构比较简单。考虑壳体结构的特殊性,通过对几种侧向分型抽芯机构的对比。最终打算采纳斜杆导滑的斜滑块抽芯机构来成型4个小孔。其优点是使模具结构形式得到了简化。本说明书具体介绍了本次设计的全部过程,通过模具设计表明该模具能够达到壳体的质量要求和加工工艺要求。关键词:塑料模具注射模壳体加工工艺AbstractPlastic is a new kind of engineering materials, the rapid pace ofdevelopment, plastics processing and forming
