摘要
塑料注塑模具是成型塑料的一种重要工艺装备,随着现代工业发展的需要,塑料制品在工业、农业、日常生活和军事等各个领域的应用范围越来越广,质量要求也越来越高,中国已经成为全球最大的塑料市场之一,塑料制品产量全球第二。
本次主要设计是对香皂盒底座盖注塑模具设计,能够全面的了解塑料模具设计的基本原则、方法.并能较为熟练的使用UG、AUTOCAD软件进行塑料模具设计,提高自己的绘图能力。为今后从事设计工作打下了坚实的基矗重点对塑件的成型原理、原料选用和注射技术进行分析。通过根据形状、尺寸、精度及表面质量要求的分析结果,确定所需的模塑成型方案,模具结构选用一模两腔,两板模,侧浇口,选用顶杆顶出方式。注射机选用HT80W1×B。设计中包含了分型面的选择、型腔的数目和排列、成型零件的结构、浇注系统等。
关键词:香皂盒底座盖;注塑模具;一模两腔;侧浇口;注射机
