Abstract

PURPOSE: To provide the subject method and device wherein a molding sand in a molding flask is pressed from the lower part by pushing up a surface plate, and simultaneously the molding sand is uniformly pressed by a plurality of sqeeze heads to mold the molding sand thereby to obtain effectively a mold for a large size material.
CONSTITUTION: A pattern 9 and a molding flask 6 are placed on a surface plate 7, and molding sand 8 is charged therein, thereafter said surface plate 7 being settled in a molding machine. Then, a molding flask stopper 5 is lifted and lowered to a height corresponding to the molding sand compression quantity and fixed thereto, and only the molding flask 6 is pushed up by a molding flask lifting and lowering ram 12 until it comes into contact with the molding flask stopper 5. Subsequently, oil is pressed in a squeeze head lifting and lowering cylinder 3 and a molding sand pressing cylinder 11, and molding sand 8 is pushed up by a pressure ram 10 until the flange 21 of the surface plate 7 comes into contact with the molding flask 6, and the molding sand 8 is uniformly pressed by squeeze heads 1 from the upper part, whereby the molding sand is applied with pressure and compressed from the upper and lower parts thereof and thus molded.
