A mold cooling apparatus comprising a pair of complementary mold arms, each arm supporting mold halves such that when the arms are moved toward one another the molds halves form plural cavities. Each mold arm supports a first air chamber to which air under pressure is supplied and a second air chamber communicating with the first chamber and having an opening facing substantially the entire length of each mold half. A diffuser plate closes each second chamber and is positioned in close proximity with its respective mold half. The diffuser plate has openings for directing air from the second chamber against the mold half. Each mold half has axial exhaust openings extending from the space between the mold half and the exterior. The mold cooling apparatus can be applied to individual cavity as well as multi-cavity mold equipment. When a multi-cavity configuration is used, supplemental cooling is utilized through introduction of compressed air from a secondary source to axial and interconnected passages within the mold halves.
