摘要

压铸机内置单向阀压射系统

主要解决传统压铸机利用浮动活塞增压的三级压射系统建压时间相对较长引起的缺陷问题。安装在增压活塞杆内的带弹簧复位的内置单向阀

可以借助弹簧的力量快速关闭锥面开始增压

缩短了建压时间。在压射活塞右端与内置单向阀之间增加压射活塞缓冲结构

慢压射时进油口的大小随着压射活塞移动而逐渐增加

实现了慢压射速度匀加速的目的。

Abstract

Injection system with inner-set check valve for die casting machine was development to solve the problems of the long establishment-time in three-stage injection system in traditional die casting machine due to use floating piston to pressurization.Inner-set check valve with spring reset which was installed in pressurization piston rod could rapidly switch off cone face with the help of spring to shorten established-pressure time by pressurization.Injected piston buffer mechanism was designed between the right end of injected piston and inner-set check valve

so the size of oil entrance during slow injection process is increased gradually with the move of injected piston

realizing the proportional acceleration of slow injection velocity.
