摘要： A vacuum die casting apparatus includes a casting cavity (10), which is evacuatable via a vacuum valve (26). A liquid casting material is pressable into the casting cavity by a piston (14) actuated by an actuator (17). A filling level sensor (20) detects a predetermined filling level of the casting material in the casting cavity. A control device (34) is connected to the filling level sensor for controlling the vacuum valve, and a position sensor (32) is connected to the control device (34) for detecting movement of the piston (14). The control device generates a closing signal for the vacuum valve (26) when the piston, after reaching the position (s1) at which the filling level sensor (20) indicates a predetermined filling level of the casting cavity (10) with casting material has been reached, is displaced in a predetermined manner.

摘要： A diecasting machine comprising a movable and a stationary die half which, when closed, define a die cavity. The diecasting machine further comprises a filling chamber for receiving liquid metal, plunger, a slidingly displaceable inside the filling chamber and mounted on a plunger rod, for ejecting the liquid metal from the filling chamber and for injecting it into the die cavity, and a device for supplying lubricants for the plunger in the filling chamber. At least one pipe or one nozzle having an opening directed towards the plunger is fastened on the plunger rod. The pipe or the nozzle is linked with a reservoir for the lubricant via a supply line. A water-based releasing agent is sprayed into the intermediate space between the plunger rod and the cylindrical inner wall of the filling chamber in the direction of the plunger during a period in which the plunger is at its final lift position after the liquid metal has been injected into the die cavity.
