| 摘要：注塑机又名注射成型机或注射机。注塑机通常是由注射装置、合模装置、液压传动系统、电气控制系统、润滑系统、加热及冷却系统、安全监测系统等组成。它是将热塑性塑料或热固性料利用塑料成型模具制成各种形状的塑料制品的主要成型设备。注塑机按照注射装置和锁模装置的排列方式来区分，可分为立式、卧式和立卧复合式。注塑机是塑料加工业中使用量最大的加工机械，不仅有大量的产品可用注塑机直接生产，而且还是组成许多工艺的关键设备。中国已成为世界注塑机生产的第一大国，促进中国注塑机设备制造业发展的原因就在于：1，与国际著名企业进行合资及技术合作；2，国企业逐渐适应了机械零部件的国际釆购方式，掌握了釆购渠道。同时，我国注塑机的生产还呈现出很强的区域特色，浙江的宁波和广东的东莞等地，已经成为我国以及全球重要的注塑机生产基地。21669 毕业论文关键词：注塑机；合模装置；注射装置 The mechanical system of injection machine design Abstract：Injection molding machine and injection molding machine and injection machine, many factories called PI JI, injection molding products is called PI JIAN. It is the thermoplastic or thermosetting material using plastic molding mold made into various shapes of plastic products mainly molding equipment. Injection molding machine according to the injection device and clamping device arrangement, can be pided into vertical, horizontal and vertical lie compound.Injection molding machine is one of the largest processing machinery, plastic processing industry in the usage not only have a large number of products available injection molding machine production directly, but also of note, blowing process of key equipment. China has become the world's largest country in machines in PCS/sets of production, the reason: to promote the development of China's injection molding machine equipment manufacturing is a joint venture with international famous enterprises and technological cooperation; Second, Chinese enterprises gradually adapted to the mechanical parts adopt international purchase way, mastered the as purchase channels. At the same time, the production of the injection molding machine of our country present a strong regional features, Ningbo in Zhejiang province and Guangdong Dongguan and other places, has become China's important production base of injection molding machine and the world.
