  • Patent number: 4539168
    Abstract: In order to remove a thin-walled wax model adhering to the walls of a first core piece and a second core piece, after solidifying, from a multi-part device for making thin-walled wax models, without damaging the wax model, after the external pressure is released, a mold-opening moment is generated simultaneously and abruptly in axially opposite directions by spring-loaded push-off bolts or directly by leaf springs in the upper parting faces and lower parting faces of the device. As a result, both the lower closing plate and the upper closing plate are separated from the annular casing and the wax model is separated from the core pieces, by a maximum of 3 mm, axially in opposite directions because the adhesion of the wax model to the walls of the core arrangements is overcome simultaneously and abruptly. Subsequently the two core arrangements and the casing are transported away from one another in an axial direction relative to one another, so that the wax model is freed.

  • Patent number: 4524817
    Abstract: The present invention relates to a centrifugal casting unit, in which a casting mold has a central distributing pan into which melts, produced inductively, are introduced. The casting unit includes workpiece-molds for precision castings, arranged on the periphery of the distributing pan. The casting unit rotates on a rotating plate in a vessel which can be evacuated. The operations which are required for a working cycle, i.e., the opening and closing of the evacuable vessel, the control of the melting and casting operations etc., are accomplished mechanically, hydraulically, and under electrical control in a fully automatic manner.
