  • Method and apparatus for press casting
    Patent number: 9004147
    Abstract: An apparatus for press casting includes a casting mold formed of a fixed mold and a first moving mold operable to move relative to the fixed mold. The apparatus further includes a second moving mold operable to move relative to the first moving mold. A mold cavity, which forms a cast product, is configured by the fixed mold and the second moving mold. When the first moving mold is moved to a first predetermined position, a molten metal passage and a gas exhaust port, which communicate with the mold cavity, are formed at positions outside the mold cavity. A communication between the mold cavity and the molten metal passage, and the gas exhaust port is cut off by the second moving mold when the second moving mold is moved to a second predetermined position while the first moving mold is maintained at the first predetermined position thereof.
