Abstract:
A system for cooling molds in a glassware forming machine, which comprises:a pair of mold arms mounted for movement toward and away from each other, at least one mold part carried by each said arm and adapted to cooperate with each other to form a glassware mold, each of said mold parts including at least one coolant passage having an inlet and an outlet adjacent to each other at one end of said mold part, a coolant manifold carried by each said arm adjacent to said one end of said at least one mold part, said manifold having inlet and outlet coolant flow passages coupled to said inlet and said outlet of said at least one mold part, a coolant source and a coolant return disposed in fixed position adjacent to said arms, and pivotal coupling means operatively connecting said coolant source and return to said manifold, said pivotal coupling means including parallel coolant flow paths for directing coolant from said source through said pivotal coupling means and said manifold inlet passage to said mold inlet, through said mold part, and from said mold outlet through said manifold outlet passage and said pivotal coupling means to said coolant return.
