摘要

开发了具有自主知识产权的真空压铸的关键技术——真空阀及其控制系统。真空阀的工作原理是利用金属液的冲击力

通过杠杆驱动关闭排气通道。真空系统采用PLC和触摸屏控制

确保真空阀处于正常可靠的工作状态。真空压铸技术已在汽车底盘悬架、变速箱体、3G通讯腔体等关键零部件上获得了应用

效果良好。

Abstract

We have developed key techniques including vacuum valve and its control equipment for high vacuum die casting. The running principle of the vacuum valve is that exhausting channel is closed by a level arm driven by liquid pressure in the valve. Vacuum control apparatus uses PLC and touch screen technology to make sure reliable working state of valve. The vacuum die casting technology has been used for producing car chassis part

transmission box and 3G housing

and desirable effects are achieved.
