  • Method for separating mold plates from a casting
    Patent number: 5229062
    Abstract: A method and apparatus for separating an upper (12) and lower (14) mold plate of a mold assembly (10) from a preformed substrate or casting (16) comprises a mold ejection apparatus (70) having a support surface (76) to receive and support the mold assembly (10). A plurality of clamps (84) pivotally connected to the support surface (76) engage the preformed substrate (16) at spaced apart intervals about the periphery of the preformed substrate (16) to restrain the substrate (16) and lower mold plate (14) against the support surface (76). The apparatus further includes a plurality of secondary hydraulic pumps (98) comprising a piston (106) and cylinder (108) assembly and a lifting bar (120) pivotally connected to one end of the piston (106). The secondary pumps (98) are supported on the support surface (76) at spaced apart intervals adjacent the periphery of the mold assembly (10).
