Abstract
A system for making foundry molds comprising the combination of a platen assembly including a platen having a top surface for supporting a mold pattern, and a ram for raising and lowering the platen in response to a controllable pressurized fluid; a mold flask supported above the platen so that upward movement of the platen positions the mold pattern thereon within the flask and closes the bottom of the flask so that the flask can be filled with sand; a sand hopper located adjacent the mold flask, and a sand magazine mounted for lateral movement between a retracted position below the sand hopper where the magazine can be loaded with sand from the hopper, and an advanced position above the mold flask for filling the cavity defined by the flask and the platen assembly with sand from the magazine; a squeeze head located adjacent the mold flask and mounted for lateral movement so that the squeeze head can be positioned over the mold flask, after the flask has been filled with sand and the sand magazine has been returned to the sand hopper, for closing the top of the flask and the flask is squeezed between the platen assembly and the squeeze head; and mold removal means located adjacent…
