This utility model relates to the field of die-casting mold technology, specifically a die-casting mold for automotive gearbox housings. It includes a die-casting mold body, with a lower mold fixedly mounted on one side inside the die-casting mold body. A double-ended lead screw is rotatably connected inside the die-casting mold body, and two symmetrically distributed horizontal plates are threaded onto the outer surface of the double-ended lead screw. Circulating heat dissipation pipes for cooling the lower mold are fixedly installed inside each of the two horizontal plates. This utility model allows the circulating heat dissipation pipes at the two horizontal plates to fit against both ends of the lower mold, and utilizes the two circulating heat dissipation pipes capable of circulating water to reduce heat loss from the lower mold. This quickly dissipates the heat generated during the lower mold's operation, accelerating the cooling and shaping of the automotive gearbox housing. Furthermore, the combination of two sets of heat sinks and heat dissipation holes further improves the heat dissipation effect and production efficiency of the die-casting mold.
