Abstract
A sand hopper ( ) is provided at its lower position ( ) with a plurality of nozzles ( ) and a plurality of squeeze feet ( ), the pressure of which is controlled, and which are located adjacent to a side of each squeeze foot. The sand hopper ( ) is supported by supporting means ( ) such that it can move vertically. A mold space is defined by a pattern plate having a pattern ( ), a flask ( ), a filling frame ( ), and a sand hopper ( ) having a plurality of squeeze feet ( ) disposed above the filling frame ( ). By discharging molding sand from the nozzles ( ), it is introduced into the mold space. The mold sand (S ) in the mold space is compacted by the squeeze feet by lowering the sand hopper toward the mold space. Since the molding machine is so arranged, both introducing molding sand into a mold space and compacting the introduced molding sand are performed at one station (a molding-sand introducing and compacting station).
