Abstract

This disclosure relates to a method and apparatus for continuously chilling or cooling mold parts which are subjected to heated products, such as the die elements of a plastic blow molding apparatus. More particularly, the disclosed method and apparatus is adapted to maintain a predetermined mold chilling temperature to permit rapid forming of plastic articles and reduce the dwell time of the plastic article within the mold. The disclosed apparatus includes a heat exchanger-evaporator, a first liquid coolant loop communicating with the heat exchanger and the mold parts to be cooled, wherein low viscosity liquid coolant is pumped through the heat exchanger and the mold parts to chill the mold parts, and a second coolant loop communicating with the evaporator within the heat exchanger and including a compressor, condenser and expansion valve. The coolant in the second coolant loop is evaporated by the expansion valve, within the evaporator of the heat exchanger, to absorb heat from and chill the coolant within the first coolant loop.
