[0026] A pouring port 10 is provided on the side wall of the convex upper mold 1, and a pressure stabilizing mechanism is provided on the convex upper mold 1, the pressure stabilizing mechanism includes a heat-conducting pressure plate 16, and the heat-conducting pressure plate 16 is preferably made of a metal material that is easy to conduct heat.
