ABSTRACT:
A thermoplastic mold for creating large sheets of building materials from recycled plastic. The mold is adapted to be used with a platen press, and has an adjustment feature for defining a mold cavity of a selected thickness. A pair of shims are preferably used to establish the mold cavity, wherein the cavity has a depth identical to the thickness of the shims. The top member or lid of the mold has an integrally defined passageway for allowing a cooling fluid to be circulated therethrough to cool the mold after a molding process. In the one embodiment, the lid has a pair of flanges extending over and engaging the shims, and an alternative embodiment the lid comprises a rectangular plate having handles defined at selected locations in the upper surface for facilitating removal of the lid from a mold recess. The sheets can be colored on one or both sides by inserting a thin sheet of colored thermoplastic material in the mold prior to pressing.
