Abstract
A horizontal stack foundry molding machine having opposed high pressure horizontally aligned rams adapted to close and then move into the open ends of a mold box filled with sand to make a high quality sand mold, such box being formed by opposed L-shape parts, the L-shape part forming the lower side of the box being horizontally movable after the rams have been retracted to shift the mold formed in the box from between said rams to a position in alignment with a pouring conveyor, a pusher being provided to move such mold from the movable L-shape part onto the pouring conveyor into juxtaposition with previously formed molds to form the horizontal stack.
Claims8
A mold traction device for moving a stack of juxtaposed molds in limited pressure contact with each other along a surface comprising drive belts operative frictionally to grip each side of such stack for movement of such stack along said surface, and unidirectional drive means for said belts, said unidirectional drive means including a piston-cylinder assembly, a longitudinally movable frame driven by said piston-cylinder assembly including racks on opposite sides thereof, and one-way clutch means interconnecting said racks and said drive belts.
