ABSTRACT:
An apparatus for automated casting of an item such as a plumbing fixture is disclosed. Female and male mold portions provide the spacing for molding the desired item between them. A fluid activated release mechanism is operatively positioned on one of the mold portions so as to assist in separating the formed item from a mold portion in a controlled and uniform manner so as to minimize damage to the cast item. In a preferred manner, there is also a fluid activated holding mechanism for temporarily holding all of the mold portions together as well as an additional fluid activated mechanism to separate the mold halves. The apparatus and method herein described is especially well suited to multiple or battery-type casting operations.
