Its technical solution includes a water tank, a docking pipe I, a fixed mold, a water pump, a docking pipe II, a movable mold and a check valve II. A movable mold is arranged at the upper end of the fixed mold. A fixed mold cooling cavity is arranged inside the fixed mold. A movable mold cooling cavity is arranged inside the upper end of the movable mold. A water tank is arranged at one end of the movable mold. A semiconductor refrigeration sheet is embedded and installed at the lower end inside the water tank. A water pump is arranged inside the water tank.
