Abstract (en)

Regulating the metal dosing in a vacuum die casting machine comprises measuring the metal melt (6) within the heat maintaining oven (7) by determining the actual value using as sensor (11, 12, 13) to exactly determine the melt dose in a casting chamber (9); comparing the measured values with theoretical values in a computer (14); and regulating an evacuation device (15) and/or a vacuum valve (5). Preferred Features: The flow through time and/or the flow through amount is regulated at the vacuum valve. The temperature of the melt is measured using a sensor (12), the sensor being connected to the computer.

Abstract (de)

Die Erfindung betrifft ein Verfahren zur Regelung von Giessparameter und insbesondere die Regelung der Dosierung der Metallschmelze (6) in einer Giesskammer (9) einer Vakuum-Druckgiessmaschine. Mit Rechner (14) verbundene Messeinrichtungen (11, 12,13) erfassen Volumen und Beschaffenheit der Schmelze und in Form eines Regelkreises erfolgt eine Regelung einer Evakuiereinrichtung (15) und/oder eines Vakuumventils (5). <IMAGE>
