1、摘要塑料是以合成树脂（高分子聚合物）为基体的固体材料。塑料有很多优良的性能：成型收缩性、流动性、相容性、可塑性等等，这些优点使它广泛的应用到我们的生活中。在今天这个高科技发达的社会，塑料成型技术的快速发展，新型工艺的不断改进，使越来越多的塑料制品应用到各行各业。注射成形是成形热塑件的主要方法，因此应用围很广。注射成形是把塑料原料放入料筒中经过加热熔化，使之成为高黏度的流体，用柱塞或螺杆作为加压工具，使熔体通过喷嘴以较高压力注入模具的型腔中，经过冷却、凝固阶段，而后从模具中脱出，成为塑料制品。本产品是日常生活用品塑料香皂盒，且实用性强。该产品设计为大批量生

2、产，故设计的模具要有较高的注塑效率，为了提高生产效率，降低成本，塑件采取一模四腔非平衡布置，浇注系统采用侧浇口成形，推出形式为推件板推出机构完成塑件的推出。塑件的工艺性能要求注塑模中有冷却系统，因此在模具设计中也进行了设计。本次的设计查阅了大量的专业资料和书籍，丰富了设计过程。关键词：注射成型，侧浇口，型芯目录摘要·············································1前言····················································41、塑件工艺分析·············
