ABSTRACT:
A mold set is formed with upper and lower mold plates having corresponding upper and lower cover plates. The mold plates have predetermined openings which become enclosed and form mold cavities when the cover plates are placed thereover. A plurality of mold sets are stacked to form a mold unit which may be placed in a storage apparatus or into a molding cycle. The molding cycle comprises a series of automated processing steps where successive mold units are sequentially processed. the steps are performed at preheating, molding, curing, mold disassembly and mold reassembly stations. At the disassembly station, the mold units are dismantled and the individual plates may be cleaned as they are conveyed to the reassembly station. At the preheating station, new mold units may be inserted into the cycle from the storage apparatus. The stations may be physically arranged into upper and lower levels whereby gravity and simple elevator mechanisms may be used to conserve time, space and energy.
