注塑机的电液比例控制系统

An Electro-Hydraulic Proportional Control-System of Injection Molding Machine

本文介绍美国ＶａｎＤｏｒｎ塑机公司生产的５５吨注塑机的电液比例控制系统的组成、原理及特点；该系统集插装、负载传感功率匹配及计算机电液比例控制等先进技术于一体，对国内新型注塑机的研究开发有一定参考价值。文末还就国内注塑机械的制造和使用提出了建议。

This paper introduced the composition, principles and traits of electro- hydraulic proportional control system for 55-ton injection molding machine which is producted by the Van Dorn Plastic Machinery Co. (In USA). The system merge advanced plug-in, load-sensing horsepowermatching and computer electro-hydraulic proportional control technologe et al. into an organin whole. It have reference to research and development mienal new type injection molding machine. At the end of paper, it also put forward some suggestics for the manufacturing and the use of mienal injection molding machinery.
