XS-ZY-250A塑料注塑成型机比例控制液压系统设计
摘要
国内运用量以及产量最高的塑机之一就是注塑机，同时为国内塑机出口的主要品种，在上世纪后期国内注塑机业获得飞快进步，年增速达到至少20%，同时逐渐构成江浙为核心的加工基地。在技术上国内制造的注塑机，已然由通用型转变成专用型、自动等。在运用上国内注塑机主要为通用型，塑料制品主要有家具以及玩具等，在市场当中占比是相当高的。部分专用型如磁性与陶瓷注塑机，因为用量并不高，未能获得机械制造行业的高度关注。然而伴随市场的持续细分化，研制有关的专用机型存在较大的价值与作用。本人设计该机器的目标主要为：为深入而全面地理解注塑机的运转机理及其架构，把掌握的理论知识和实践活动紧密联系起来。

At present, the most common and most produced plastic machine in China is injection molding equipment, is also the main force of China's plastic machine exports since the 1980s, China's injection molding machine industry has developed rapidly,with an annual growth rate of more than 20%, and has gradually formed Zhejiang Ningbo, Guangdong Processing bases mainly in Dongguan and Shunde. In terms of technology, the injection molding machines produced in China have developed from ordinary models to mainframes, full electric motors, electro-hydraulic composite machines and special injection molding machines. In terms of application, China's injection molding machines are mainly general-purpose, and the production of general plastic products such as toys, stationery, daily necessities, furniture, and decoration materials has the largest market share. Some special-purpose injection molding machines, such as ceramic injection molding machines for producing fine ceramic components and magnetic injection molding machines for producing neodymium-iron-boron electronic components, have not received much attention from machinery manufacturers due to the small amount. However,with the further segmentation of the market, it is of great significance to develop relevant special models. The main purpose of constructing this equipment is to realize: to understand the operation mechanism and structure of the injection molding machine as awhole, and to closely link the theoretical knowledge and practical activities.
