  • Patent number: 11964323
    Abstract: A three-plate pressure die casting mold for producing at least one metallic die casting part by die casting a metal melt, includes first, second and third mold parts and at least one mold cavity as well as a sprue system. In the third mold part there is at least one spring-loaded pressure element which, when opening the die casting mold, presses the sprue produced in the sprue system against the first mold part, whereby the sprue is retained and tears off from the die casting part in a defined manner. A method for pressure die casting using the three-plate pressure die casting mold is disclosed.

  • Publication number: 20230330745
    Abstract: A three-plate pressure die casting mold for producing at least one metallic die casting part by die casting a metal melt, includes first, second and third mold parts and at least one mold cavity as well as a sprue system. A relatively movable pressure plate is arranged in the third mold part, which, when opening the die casting mold, presses the sprue produced in the sprue system against the first mold part, whereby the sprue is retained and tears off from the die casting part in a defined manner. A method for pressure die casting using the three-plate pressure die casting mold is disclosed.

  • Publication number: 20170028463
    Abstract: A method is provided for producing a die-cast part by means of a die-casting die, wherein air contained in the die-casting die is sucked out. A moisture contained in the air that is sucked out is measured. In the method, the moisture is measured while the air is sucked out. A device for producing a die-cast part, which device has a diecasting die, a suction apparatus for sucking out air present in the die-casting die, at least one sensor for detecting the moisture in the air that is sucked out, and a control apparatus for controlling the device, is designed to perform the method.
