COOLING DEVICE FOR GLASS CONTAINER FORMING MACHINE

摘要

A cooling system (10) for neck ring molds (19) in a glass molding machine having retractable parison-forming molds (16, 18) engageable with the neck rings (19) employs air jets (F) directed at exposed portions (56) of the neck ring molds (19). The neck ring molds (19) are configured to extend out of the bottom of the main parison molds (16, 18) and to engage with neck ring hangers (21). The neck ring molds (19) are configured sufficiently long that a space (d) is created between the bottoms of the main parison molds (16, 18) and the hangers (21) to permit direct access to portions (56) of the neck ring molds (19). Air supplied in the form of air jets (F) from a pair of cooling air plenums (52) is directed at the exposed portions (56) of the neck ring molds (19) to provide cooling.
