Casting precoated sand shell mold demolding device

The casting precoated sand shell mold demolding device comprises two supporting plates, the upper ends of the two supporting plates are fixedly connected with an injection molding mechanism, the lower ends of the supporting plates are fixedly connected with a demolding mechanism, the upper end of the injection molding mechanism is fixedly connected with a mounting mechanism, the mounting mechanism is internally connected with a pressing mechanism in a threaded mode, and the pressing mechanism is fixedly connected with the demolding mechanism. According to the cooling device, the rotating plate and the threaded rod are arranged, so that the lower pressing block is conveniently driven to descend to cast a casting in the injection molding groove under the sliding limiting action of the threaded hole and the sliding groove, and the pump body and the water inlet pipe are arranged, so that cooled water is conveniently and rapidly injected into the cooling groove; and a water outlet pipe can be used for carrying out
