Abstract: A system and method of cooling glassware molds by directing liquid coolant to the blank or blow mold halves of a glassware forming machine through an enclosed pivotal rotary union-type structure. A coolant manifold is carried by each pivotal mold arm, and communicates with coolant inlet and outlet ports at the lower end of each mold part. The manifold is connected by a floating shaft seal and a rotary union assembly and a crank arm to a coolant source and coolant return in the section box of the associated machine section. Each pivotal connection—i.e., between the section box and the crank arm, between the crank arm and the rotary union assembly, and between the rotary union assembly and the floating shaft seal—comprises a bi-directional rotary union for feeding liquid coolant to the manifold and mold parts, and returning coolant from the manifold and mold parts. Dynamic floating seals between the coolant manifold and the mold parts, and between the coolant manifold and the rotary union mechanism, accommodate relative motion between these components as the mold parts are opened and closed.

Abstract: A glassware forming mold that includes a body of heat conductive construction having a central portion with a forming surface for shaping molten glass and a peripheral portion spaced radially outwardly of the central portion. A plurality of coolant passages extend in a spaced array through the peripheral portion of the mold body, and liquid coolant is directed through such passages for extracting heat from the body by conduction from the forming surface. A plurality of openings extend axially into the body radially between at least some of the liquid coolant passages and the forming surface for retarding heat transfer from the forming surface to liquid coolant in the passages.
