  • Die change apparatus and die carrying-in device for use in flaskless molding machine
    Patent number: 8813819
    Abstract: Provided are a die change apparatus for use in a flaskless molding machine capable of mounting dies for producing a casting mold on die bases even when the dies have a great thickness, and a die carrying-in device used therein. The die carrying-in device comprises a first movable plate provided so as to be slidable along a die carrying-in direction toward a first die base, and a second movable plate placed so as to face the first movable plate in a standby position. A die drive source causes dies which have been positioned in a height direction to be detached from the movable plates, move toward the die bases, and be supported by clamping elements. An intersection drive source causes at least one of the first movable plate and the second movable plate to move in a direction to intersect the die carrying-in direction independently of the other.
