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