发明名称 Modular slush molding machine
摘要 A method and an assembly for practicing that method wherein an article is molded of a heat-fusing material or plastisol in a mold having first and second groups of liquid passages disposed adjacent the mold surface for controlling the temperature over respective first and second areas of the mold surface. The mold is supported for rotation about an axis by a stationary pedestal. A movable module supports plastisol storage tanks, heat exchangers, valves, conduits, etc., for supplying the plastisol to the mold. The movable module also supports a dump tank which is disposed beneath the mold for receiving and retrieving the liquid plastisol which is emptied or dumped from the mold when it is rotated to an inverted position. There is included first and second liquid circuits including a pump and heat exchanger for supplying liquid at different temperatures to the passages associated with the mold. All of the passages are supplied with heated liquid to maintain the temperature of the first and second areas of the mold surface at a non-gelling temperature and a liquid plastisol coating is applied to the mold surface.
