Abstract

L'invention concerne une machine de coulée sous pression avec multiplicateur. La machine de coulée sous pression comprend un piston de travail 2 coulissant dans un cylindre de travail 1, un piston de multiplicateur 5 coulissant dans un cylindre de multiplicateur 4, de même qu'un espace de précontraintte 6 prévu devant le piston de multiplicateur 5, l'espace 11 du cylindre de travail pouvant être relié, du côté du piston, à la conduite d'alimentation de l'agent de pression 9 via une soupape de retenue 10 exposée à la pression du piston dans le cylindre de travail 1. L'invention est utilisée pour la coulée de métaux sous pression en accédant plus aisément à la soupape de retenue et sans affaiblir le piston de multiplicateur.The invention relates to a die-casting machine with a multiplier. The die-casting machine comprises a working piston 2 sliding in a working cylinder 1, a multiplier piston 5 sliding in a multiplier cylinder 4, as well as a prestressing space 6 provided in front of the multiplier piston 5, the space 11 of the working cylinder which can be connected, on the piston side, to the pressure medium supply line 9 via a check valve 10 exposed to the pressure of the piston in the working cylinder 1. L The invention is used for die casting metals with greater ease of access to the check valve and without weakening the multiplier piston.
