The publication number is: CN220295683U, which relates to the field of mold technology, including a base, a cooling mechanism, a lower mold, an upper mold, an auxiliary mechanism, a hydraulic cylinder and a convenient mechanism. A cooling mechanism is arranged in the middle of the upper end of the base, and a lower mold is arranged on the inner side of the cooling mechanism. An upper mold is arranged directly above the lower mold, and the upper end of the upper mold is connected to the auxiliary mechanism. When the air-conditioning panel is stamped, the right water pump draws the cold water inside the cold water tank into the hollow slot frame through a pipeline. Since the lower mold is embedded in the inner side of the hollow slot frame, the stamping parts of the air-conditioning panel can be effectively cooled, the heat can be dissipated, and the heat accumulation can be reduced. At the same time, the left water pump draws the water inside the hollow slot frame into the cold water tank through a pipeline for re-cooling to maintain the low temperature requirement of the hollow slot frame. The cooling water is in a circulating state, which can reduce the waste of water resources, but the following problems still exist:
