摘要

立体式激冷排气阀是在普通激冷排气阀的基础上发展而来

将"一"字直线式的排气通道设计成一种"W"型曲线结构

其主要目的是增加排气道的宽度

增大排气面积。当将此类型真空阀应用于真空压铸工艺中

同等的真空压铸参数下

其抽气效率等同于机械截止真空阀

其可靠性等同于普通激冷排气阀。基于立体式激冷排气阀的特点

开发了真空控制系统

并针对实际生产的油底壳零件进行了计算机填充模拟、模具方案优化以及试验

验证了立体式激冷排气阀具有抽气效率高、可靠性高、维护成本低的优点。

Abstract

Space formula chilling exhaust valve is a new Zig-Zag vavle developed from traditional chilling exhaust valve

in which the straight-line exhaust passage is modified to be a " W" shape curve structure to increase the width of the exhaust duct and entire exhaust area.So at the same vacuum die casting parameters

the extraction efficiency is equivalent with mechanical stop vacuum valve

meanwhile the reliability is equivalent with normal chilling exhausting valve.Based on the characteristics of space formula chilling exhaust valve

the vacuum control system was developed.The results demonstrate that the space formula chilling exhaust valve has advantages of high extraction efficiency

high reliability

low maintenance cost.
