摘 要：注塑机关键是合模机构部分。合模机构是注塑机最重要的机械部件，注塑机的合模机构形式很多，常用的机构主要可分三种：全液压式，液压-机械式，电子机械式。液压机械合模机构是目前使用最为普遍的合模机构。液压机械合模机构通常有移模液压缸和曲肘连杆两部分串联而成，习惯上也称为肘杆式合模机构。在开合模过程中，这种机构能实现慢-快-慢的运动过程，提高了合模速度，节约了能耗并提高了效率[1]。

Design Of Clamping Machanism For Plastic Injection Machine
Student：
Teacher：
Abstract: Clamping mechanism is the Key part of the Injection molding machine. Clamping
mechanism is the most important component of Injection molding machine, Clamping mechanism has
many forms, but commonly used can be divided into three types: hydrostatic transmission,
hydraulic-mechanical and electronic mechanical. Hydraulic mechanical is most widely used now.
hydraulic-mechanical Clamping mechanism is always consist of Hydraulic cylinder and song cubits
connecting rod. It also be called Cubits long pole type shut the mould institutions. In the process of
combining a model , this mechanism can achieve slow -fast-slow ‘s speed movement process; improve
the speed of spotting and it also can save energy consumption and Improve efficiency.
