In the molding of hot glass material into glass containers, an improved system and method is disclosed for providing cooling air to mating halves (40, 42) during the entire process and an additional degree of cooling during the portion of the process when hot glass material is enclosed within mating mold halves. Countercurrent cooling air flows are established in separate arrays of cooling passages (62, 64, 76, 78) located in each mold half, with one of the cooling air flows being capable of actively cooling the mold halves over the full cycle rather than only when the mold halves are in their closed position. The cooling air flows in the separate arrays of cooling passages allows separately timing and control of the cooling air flows supplied to the arrays of cooling passages in the molds. |
