ABSTRACT:
A mold handling system comprising an indexing turntable for carrying a multiplicity of molds in concentric inner and outer rings with the outer ring located at a lower elevation than the inner ring, a conveyor for transporting a multiplicity of molds to a mold transfer station adjacent the turntable, the transfer station including a mold transfer shuttle having a tandem pair of pusher plates for simultaneously (1) transferring a mold from the radial location of the outer ring of molds to the radial location of the inner ring of molds on the turntable, and (2) transferring a new mold from the conveyor to the radial location of the outer ring of molds, the pusher plates directly engaging the respective molds transferred thereby, an elevator mechanism for transporting molds back and forth between the different elevations, the upward movement of the elevator mechanism lifting a mold from the outer ring to the elevation of the inner ring so that the shuttle mechanism transfers the lifted mold directly from the elevator mechanism to the inner ring while simultaneously transferring a new mold from the conveyor onto the elevator mechanism, and the downward movement of the elevator mechanism lowers the new mold into the outer ring, a pouring station adjacent the turntable at a position downstream of the transfer station for filling the molds on the turntable with molten metal, and a mold discharge station for removing molds from the turntable.
