Abstract
A molding apparatus is disclosed which includes a first support having spaced apart vertical posts, and a first set of mold halves positioned between the vertical posts. A second support is provided having positioned thereon a second set of mold halves. A clamp bar is positioned on the vertical posts adjacent the second support so as to extend across the mold halves of the second set of mold halves. A grip member secured to the first support is movable between an engage and disengage position, wherein in the engage position a clamp engages the grip member and the clamp bar so as to drive the respective sets of mold halves into sealing contact with each other, so as to form two mold cavities. In the disengage position, the grip member is clear of the clamp so as to permit the clamp to also act as a device to separate the supports when the molding process is over. Methods of using this equipment in an automated rotational molding process are also disclosed.
