Ejector for die casting machine and method of controlling the same

压铸机的注射装置及其控制方法

Abstract

Provided is an ejector, simple in structure, for a die casting machine and a method of controlling the ejector capable of die-casting with high quality. The ejector for a die casting machine, wherein a plunger is pushed forward to eject molten metal contained in a sleeve, has an ejector provided with a plunger driven by a motor at a high and a low speed, a pressure mechanism for imparting a pressure on the molten metal by means of the plunger, and a shift lock mechanism for blocking the shift between the plunger and the pressure mechanism during the time when the molten metal is under pressure.
本发明提供一种压铸机的注射装置及其控制方法,其能够实现设备的简化和铸件的品质提高。所述压铸机的注射装置通过使柱塞前进来将套筒内的熔液注射填充至模具内,所述压铸机的注射装置具备:注射填充装置,其通过马达使柱塞以低速和高速前进;升压保持装置,其经由柱塞对熔液施加压力;以及移动抑制机构,其在对熔液施加压力的期间抑制柱塞和升压保持装置的移动部之间的相对移动。
