摘要 塑料模具工业在中国的制造业市场发展越来越迅速，模具设计和制作市场也随之变得越来越大，也因此塑料制品在我们生活的方方面面扮演者不可或缺的角色，本课题设计的目的是要为魔方机械手传感器支架来设计一整套注塑模具，通过分析外部结构和尺寸，对分型面位置和模具的型腔排列进行了比较详细合理设计，模具决定采用一模四腔H形排列方式，分型面设计选在产品中间位置处，浇口采用侧浇口方式。再由塑件成型所需注射量的大小对注塑机进行了选定XS-ZY-125型号注塑机，最后还对注塑机相关重要参数做了校核。最后为生产魔方机械手传感器支架的塑料模具设计一套冷却系统和排气系统。 关键词：魔方机械手传感器支架；一模四腔；分型面；侧浇口；排气系统 Abstract The plastic mold i
