香皂盒塑件注塑模具设计 Desig
n OF INJECTION MOULD FOR PLASTIC PARTS OF SOAP BOX 摘要 本次设计是针对香皂盒的上盖板与下盖板的注塑模具设计。模具设计分为多个步骤，其中主要有分析塑件产品性能要求、分析和选择材料、设计与计算动模与定模尺寸、设计浇注系统、设计导向机构和脱模机构等。设计过程运用到了UG和CAD设计软件来设计和优化模具的组成部分，并对动模与定模、主流道、分流道、浇口等重要部件进行选择和尺寸计算；完成模架、排气及冷却系统、浇注系统、导向系统、脱模机构的设计，并对其中的成型零件进行设计。对得到的数据进行整理与修改，最后对各部分的零件图进行装配并书写设计说明书完成本次设计。 关键词：香皂盒；型腔；型芯；注塑机 Abstract This desig
