Disclosed is a system for directing cooling air onto a neck ring in a glassware molding machine. The glassware molding machine is of the type including a stationary blank mold station with a plunger cylinder having an axis; a neck ring arm selectively aligned with the blank mold station, and at least one neck ring carried by the neck ring arm and movable into a forming position which is coaxially aligned with the axis. The system for directing cooling air includes at least one air plenum disposed at the blank mold station. The air plenum has an internal cavity for receiving cooling air flowing laterally inwardly toward the axis, and has at least one outlet opening adjacent the axis. The system also includes a plunger wear plate which overlays a portion of the air plenum. The plunger wear plate has an array of axially oriented openings for receiving air directed from the air plenum. The system further includes a number of openings in the neck ring arm for receiving air from the openings in the plunger wear plate and a number of air passages in the neck ring for receiving air from the neck ring arm openings. |
