ABSTRACT:
An automated molding apparatus has a continuous movable belt trained about a pair of spaced apart sprocket pulleys rotatably mounted to a main support frame. A plurality of female dies are equidistantly mounted to the belt for mating with a plurality of male dies reciprocatively mounted in a plane above the female dies. A heated feeder is provided for introducing a predetermined amount of melted mix into the female dies prior to mating with the male dies. To insure that the resulting molded product is properly hardened, the female dies are adapted with internal channels connected to a liquid cooling system. The molding apparatus is readily adaptable for hydraulic operation and may be readily automated by an electrically actuated control and timing system.
