摘要

Die casting machines of cold chamber and a hot chamber die-casting, and.Methods for shaping a metallic article and to apply pressure on the first and second portions of the mold is described as a die casting machines which comprises an actuator for closing the mould capableTo induce a pressure closing selectively in the first and second plates to force them to a closed position in which portions of the mold are pressed against one another along aParting line.A shirt of injection is mobile in relation to the portions of the mold between a distal position in which the shirt of injection and the portions of the mold are spaced; and a position of the injection in which the shirt of injEu00e7u00e3o fit portions of the mold in an entry opening when the first and second plates are in their closed position.The shirt of injection applies a contact pressure when she fits the transverse portions of the mold.The closing pressure is unevenly distributed in the dishes so as to compensate for the contact pressure transverse to have a pressure molding resulting in effective portions of the mold is d.Istribuu00edda substantially uniform manner through the parting line.
