ABSTRACT:
An automated matchplate molding machine includes a cope flask, a pattern plate and a drag flask for creating formed sand molds. A lock is provided to lock the drag flask to the platen table of the molding machine during desired stages of an individual sand molding sequence. The lock between the drag flask and the platen table may include actuated pins which engage corresponding detent structures such as tapered holes integral with the drag flask and prevent lateral migration of the drag flask relative to the platen table. Additionally, cope flask actuators are provided which vertically support and are operable to raise the cope flask relative to the squeeze head to facilitate release the cope mold from the cope flask.
