摘要 本课题完成60g中小型注塑机的液压系统设计。塑料注射成型机是热塑性制品的成型加工设备，它将颗粒塑料加热熔化后，高压快速注入模腔，经一定时间的保压，冷却后成型为塑料制品。本次设计主要完成了以下设计内容：注射成型原理和理论研究及注射成型工艺过程分析； XS-Z60A型注塑机节能低耗高效的液压系统设计，绘制工作原理图；液压结构设计与绘图。液压缸设计中，缸体与缸盖采用法兰连接方式，活塞杆与活塞螺纹采用组合式结构中的螺纹连接。液压控制装置的结构采用块式集成设计块式，做成通用化的6面体油路块（集成块）。本设计中液压站的设计，采用卧式安装液压泵，液压泵直接装在支架的止口里，然后依靠支架的底面与底板相连，再与带底座的电动机相联。实现泵与电动机的连接。 通过这次设计，真正了解了液压系统内部结构，达到了把所学的知识运用到生活生产实践中去。 关键词：注塑机；液压系统；液压缸；液压站 ABSTRACT The completio
