ABSTRACT:
A molding apparatus has a first support with two vertical posts, a first set of two mold halves, and a grip positioned thereon. There is also a second support having positioned thereon a second set of two mold halves. A clamp bar is positioned over the two supports in a vertically movable manner so as to retain the sets of mold halves together to form two mold cavities. The clamp bar interfits and rides along the vertical posts and so as to simultaneously clamp multiple molds closed. There is also a lock for locking the clamp bar to the vertical posts, thus clamping the molds closed without the need for nuts or bolts. A hydraulic clamp is used to assist in moving the mold halves into a tight sealing position.
