Abstract

Es wird eine Vakuum-Druckgießmaschine vorgeschlagen, bei welcher die Formhälften (3, 4) mittels einer Dichtungsanordnung (16) gegeneinander abgedichtet sind. Beim Zusammenfahren der Formhälften entsteht aufgrund der überstehenden Dichtung ein zu komprimierendes Luftvolumen, wobei eine Verdrängung der so eingeschlossenen Luft bis in die Metallschmelze (8) des Warmhalteofens (10) dadurch vermieden wird, daß der Gießkolben (7) während dieses Vorgangs das Ansaugrohr (9) verschließt.

Figure 00000001
A vacuum die casting machine is proposed, in which the mold halves (3, 4) are sealed off from one another by means of a sealing arrangement (16). When the mold halves are moved together, an air volume to be compressed arises due to the protruding seal, displacement of the air thus trapped into the molten metal (8) of the holding furnace (10) being avoided by the fact that the casting piston (7) during this process the intake pipe (9 ) closes.
