Abstract: A diecasting machine casting unit includes a casting chamber body having a casting chamber with a casting material inlet and outlet. A casting piston is movable forward in a longitudinal direction in the casting chamber to discharge casting material from the casting chamber under pressure via the outlet, and is movable back, whereby casting material is feedable into the casting chamber via the inlet. The casting piston extends through a through-passage of the casting chamber body from outside into the casting chamber. An area of free space of the casting chamber is formed between an outer lateral surface of the casting piston and an inner wall surface of the casting chamber body transversely relative to the casting piston longitudinal direction by an outer cross section of the casting piston being appropriately smaller than an inner cross section of the casting chamber body.

Abstract: A protective gas device for the melting furnaces of pressure die-casting machines, in particular for processing a magnesium melt. A collection container of a mixing device for the components of a protective gas, which covers the melt to prevent oxidation or other damage, is configured as a pressure accumulator and the orifices for feeding the protective gas into the melting furnace are provided with inlet nozzles. Gas flow to the inlet nozzles is regulated by metering devices. The operating pressure is equal to or less than the pressure in the pressure accumulator of the mixing device, but high enough to atomise the jets and produce a turbulent inflow behind the inlet nozzles. Said pressurized protective-gas distribution permits the metering of gas into various furnace chambers or furnaces without repercussions. A uniform concentration of the protective gas can be achieved in all areas by the selective arrangement of the inlet nozzles.

Abstract: In a spray element for a spray head for spraying the molds of pressure casting machines, a control piston for the release of the parting agent supply is disposed beside the spray nozzle and a connecting passage opens in a chamber of the housing in which one end of the control piston is sealingly guided, while its second end lies with a sealing ring before a chamber fed with parting agent. In the case of the application of control air the sealing ring is shifted out of its cylindrical section 26 into the chamber, so that the feed of parting agent to the spray nozzle is released. If the control air is shut off, then the sealing ring closes the delivery of the parting agent, and the second, larger end of the control piston exercises upon its return movement a reverse suction effect on the connecting passage. Any after-dripping of parting agent is securely prevented.
