Fast cooling system of aluminum alloy wheel low-pressure casting mold

The utility model relates to a fast cooling system of an aluminum alloy wheel low-pressure casting mold. An upper mold, a lower mold and an edge mold are closed to form a wheel-shaped mold die cavity to be processed, the end surfaces of the edge mold, the lower mold and the upper mold with the thicker wall are respectively provided with water grooves, the opening part of each water groove is fixedly provided with a cover plate in a sealed way, and two end parts of each water groove are respectively provided with a water inlet and a water outlet. The cooling system has the advantages that cold grooves are respectively formed in the upper surface of the upper mold, the upper surface of the edge mold and the lower surface of the lower mold, the thicker wall of the mold is fast cooled through the water cooling new technique, the problem of poor casting workblank forming is solved, the conception is ingenious, the design is scientific, and the operability is high.
