摘要

自主研发了一套基于工控机和PLC的能从模具型腔、压铸机压室和模架多向抽真空的高真空压铸技术

包括液压驱动式真空阀及其真空控制系统。结果表明

液压驱动式真空截止阀结构简单

维护工作量小

可靠性高。以工控机为上位机

PLC为下位机的分布式控制系统拥有检测型腔真空度、湿度、压射参数

如速度、位移、压力等

并实时显示曲线及数据追溯功能。多向抽气高真空压铸技术具有排气速度快、扩展方便、过程控制可视、数据处理能力强的优点。

Abstract

A multi-directional vacuum system based on IPC and PLC was developed

which exhausted from mold cavity

sleeve and die carrier.The system consists of hydraulic vacuum valve and vacuum system controlled by IPC and PLC.The results show that the hydraulic vacuum valve has the features of simple

easily maintenance and high reliability.The vacuum system based on IPC-PLC method possesses some functions such as detection of vacuum level and moisture as well as some shot parameters including velocity

pressure and stroke.Meanwhile

real-time curves of above parameters can be shown.High vacuum die casting with multi-way venting has the advantages of fast venting

powerful data-processing capacity.
