II 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。

Abstract
Critical of the injection molding machine is part of the clamping mechanism. The
clamping mechanism is the most important mechanical components of the injection
molding machine. Many institutions in the form of injection molding machine clamping,
Common institutions mainly divided into three: Fully hydraulic, Hydraulics – Mechanical,
Electronic mechanical. Hydraulic mechanical clamping mechanism is the most widely
used clamping mechanism. Hydraulic and mechanical clamping mechanism is usually a
two-part series of the hydraulic cylinder and toggle rod shift mode. The habits also called
on the toggle clamping mechanism. In the process of opening and closing mold. Such
institutions can be slow - fast - slow movement, Clamping speed, energy savings and
improved efficiency.
Keywords: Clamping mechanism; Double-toggle; Open-Die; Hydraulic pressure
