    Abstract: A die casting machine has a carousel and a plurality of molds disposed around the carousel. The carousel rotates about a central axis, such that each of the plurality of molds comes into a position for casting in turn. Each mold has a toggle mechanism and extraction pins. A gripping mechanism may extend up through a hole in the carousel table to couple the toggle mechanism to an actuator. At least one of the pins may have a pin brake such that the pins remain in position when the mold is opened, suspending a newly cast metal part in mid-air, when the brake is activated. When the brake is deactivated, the pins may retract, and the part may be removed without damaging the cast part.

    Abstract: Exemplary embodiments described herein relate to methods and systems for casting metal alloys into articles such as BMG articles. In one embodiment, processes involved for storing, pre-treating, alloying, melting, injecting, molding, etc. can be combined as desired and conducted in different chambers. During these processes, each chamber can be independently, separately controlled to have desired chamber environment, e.g., under vacuum, in an inert gas environment, or open to the surrounding environment. Due to the flexible, independent control of each chamber, the casting cycle time can be reduced and the production throughput can be increased. Contaminations of the molten materials and thus the final products are reduced or eliminated.

    Abstract: A method for making an equiaxed investment casting. The method utilizes an ultrasonic generator to send an ultrasonic pulse into molten metal in an investment casting mold. The investment casting mold is positioned within a working zone of furnace having low output induction coils for generating a convection current in molten metal. The ultrasonic pulse separates dendrites growing from the face of the mold inward into the molten metal. Instead, equiaxed grains can nucleate within the molten metal. In addition, the ultrasonic pulse and the low output induction coils circulate the molten metal as solute is rejected from solidifying equiaxed grains. The mixing reduces the effects of segregation in the solidifying alloy and assists in nucleating equiaxed grains.

  • Publication number: 20110155288
    Abstract: This invention discloses an L,R,C method and equipment for casting amorphous, ultracrystallite and crystallite metal slabs or other shaped metals. A workroom (8) with a constant temperature of tb=?190° C. and a constant pressure of pb=1 bar, and liquid nitrogen of ?190° C. and 1.877 bar is used as a cold source for cooling the casting blank. A liquid nitrogen ejector (5) ejects said liquid nitrogen to the surface of ferrous or non-ferrous metallic slabs or other shaped metals (7) with various ejection quantity v and various jet velocity k. Ejected liquid nitrogen comes into contact with the casting blank at cross section c shown in FIG. 2. This method adopts ultra thin film ejection technology, with a constant thickness of said film at 2 mm and ejection speed Kmax of said liquid nitrogen at 30 m/s.

  • Publication number: 20100276107
    Abstract: The invention relates to a venting unit for a die casting device which has a mold cavity that is adapted to be filled with liquid casting material and a gas suction device that is connected to the mold cavity for extracting gas from the mold cavity by suction, the venting unit comprising a flow labyrinth, the inlet of which is adapted to be connected to the mold cavity and the outlet of which is adapted to be connected to the gas suction device. In order to develop the venting unit in such a way that it makes improved evacuation of the mold cavity possible without the risk that liquid casting material can escape from the venting unit, it is proposed according to the invention that the flow cross-section of the flow labyrinth is variable. Furthermore, a die casting device with a venting unit of this kind is proposed.

  • Patent number: 7275583
    Abstract: An apparatus for processing molten material into a desired shape comprises a die or mold forming a cavity to receive molten material and to allow its solidification within the cavity. A source of vacuum is connectable to the cavity for sucking air out. A hollow after-pressure cylinder is in communication with the cavity so as to receive a portion of the material. The after-pressure cylinder has a first end for connection to the cavity, and a second, opposite end. In the region of the second end is a connection opening for connecting the vacuum source. An after-pressure piston is moveable in the after-pressure cylinder to press its portion of material into the cavity to compensate for any shrinkage of the material in the cavity. There is a drive for moving the after-pressure piston in its after-pressure cylinder into three different positions, i.e.
