Abstract

An injection assembly, for pressure die casting systems, has an injection cylinder adapted to inject liquid metal into a casting cavity; the injection cylinder is actuated by a hydraulic flow of an oil-pressure controlled circuit; the oil-pressure controlled circuit includes a hydraulic cushion which blocks and releases the flow of the hydraulic fluid in the injection cylinder and provides a counter-pressure of preset value to control the injection speeds and to prevent cavitation in the injection cylinder.

Abstract

The invention relates to a vacuum die casting-machine that has a casting mold with two mold halves between which a mold cavity is formed, said cavity communicating with a casting chamber that is to be provided with molten metal from a holding furnace. A vacuum is generated in the mold cavity via an evacuating device. Furthermore, a pressure-ascertaining device is provided for ascertaining the mold cavity pressure, and at least one control device is provided, by means of which the mold cavity pressure can be regulated.
