Abstract: A foundry molding machine is provided with a pattern plate surrounded by and movable in a well form. In a preferred form springs bias the well form upwardly around the pattern plate to form a well. The pattern plate and well form are mounted on a squeeze table and cooperate with the underside of a conventional flask which in turn engages an upset to form a mold chamber for receiving molding sand. In such preferred form the sand is blown under very low pressure into the chamber through a slotted squeeze head. As the squeeze table moves upwardly, sand is initially squeezed from the top against the squeeze head while the flask, upset, well form and pattern plate move upwardly as a unit. When a selected level of the flask is reached, preferably when the top is flush with the squeeze head, upward movement of the upset is stopped while the table continues upwardly. The pattern plate then telescopes upwardly within the well form while the flask and well form are held fixed.

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L-shape parts, the L-shape part forming the lower side of the box being horizontally movable after the rams have been retracted to shift the mold formed in the box from between said rams to a position in alignment with a pouring conveyor, a pusher being provided to move such mold from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.
