探测器后盖模具设计及其型腔仿真加工
摘要: 本课题来源于盐城科城电子有限公司，任务是探测器后盖模具设计。针对探测器制品表面光滑度要高问题, 分析了探测器制品的工艺特性, 设计潜伏式浇口。通过制品质量计算选择了注塑机（SZ-100/60型）, 并且通过对零件的工艺分析确定型腔数量、选挥分型面、设计型芯和型腔，由于设计的零件属于中小型所以采用了一模二腔的注塑形式。本模具选用的是标准的模架，并对动、定模之间的导向和定位、工件推出机构、浇注系统的总体布置方案、垫块的尺寸、推出导向机构、复位机构进行了设计，并且对组成模具型腔的各个部分进行了计算，对所选的注塑机的各个参数进行了校核。模具推出机构采用的是顶杆推出 ，根据制品形状对顶杆进行了特殊设计。制品形状的特殊性在加工方面采用了电脉冲加工。本模具结构紧凑, 工作可靠, 成型工件满足质量要求，较好地实现了设计要求。
