A casting chamber has a casting plunger guided therein. In order to supply the casting plunger with lubricant on its outer circumferential surface, the casting chamber has a lubricant channel which runs round in a ring and is supplied via a feed line with lubricant which, after flowing through the lubricant channel, passes into a discharge line for the lubricant.

Casting set for a diecasting machine

In a die-casting machine for producing castings from metals or metal alloys, which castings have a low content of gas, pores and oxides, melt is drawn by means of a vacuum out of a holding device (10) via a suction tube (11) into a casting chamber (3). A casting plunger (7) closes the inlet opening (16) to the casting chamber (3). In order to achieve as low as possible mechanical surface pressure due to flow of the melt, and fluviatile erosion of the die-side end of the inlet opening (16), and thus avoid high wear of this inlet edge or of the casting chamber with casting plunger, a planar or linear inlet cross-section (24, 27) as well as a curved deflection surface (20) on the casting plunger (7) are provided.

Die-casting machine

A diecasting process for producing cast pieces for metals or their alloys by means of a horizontal cold chamber diecasting machine. The diecasting machine includes a diecasting mold held under a vacuum, a fill chamber coupled to the diecasting mold, a holding furnace containing metal melt, a suction pipe partially immersed in the holding furnace and coupled to the fill chamber, means for transporting metal melt from the holding furnace through the suction pipe into the fill chamber under a vacuum, and means for moving the metal melt from the fill chamber into the diecasting mold. During the dosaging phase when the fill chamber is filled with metal melt, gases and lubricant vapors are developed upon entry of the melt into the fill chamber. The process includes the steps of maintaining the vacuum in the fill chamber during the dosaging phase until the gases and lubricant vapors so developed have been substantially extracted and maintaining the vacuum in the fill chamber to its maximum extent until the diecasting mold is completely filled with the metal melt.
