The existing cooling pool is an open structure. If multiple castings are placed in the cooling pool at one time, a large amount of steam will be generated to cause burns to the staff." To this end, the technical solution to this problem is "including a box body, a cooling chamber is opened in the box body, the center position of the cooling chamber is rotatably connected to the placement box, one side of the box body is fixedly connected to the motor bin, the motor is fixedly connected to the motor bin, the driving sprocket is fixedly connected to the motor shaft, the shaft end of one side of the placement box passes through the box body and the side wall of the motor bin, is located in the motor bin and is fixedly connected to the driven sprocket, the driving sprocket and the driven sprocket are sleeved with chains, the top of the box body is fixedly connected to a water pump, and one side of the box body is fixedly connected to a water tank", etc.
