The outer diameter of the circular plate 11 is matched with the inner diameter of the inner cavity 10, so that the circular plate 11 can slide along the inner wall of the inner cavity 10, and the circular plate 11 can divide the inner cavity 10 into two parts, so that the inner cavity 10 above the top of the circular plate 11 can receive the cooling water 12 sprayed from the water outlet 9, and the mold body 1 at the top of the circular plate 11 can be continuously cooled until it is evaporated by high temperature, and the inner cavity 10 above the bottom of the circular plate 11 can temporarily store the cooling water 12, so that there is enough cooling water 12 in the sleeve 3 to supply, and the cooling water 12 at the bottom can also generate upward buoyancy to the circular plate 11, so that the force generated when the circular plate 11 and the mold body 1 at the top of the circular plate 11 slide down is consumed, thereby facilitating the protection of the mold body 1 and the bottom of the circular plate 11, slowing down the speed of wear and aging of the bottom of the mold body 1, and the cavity 2 is used to place the hexagonal bolt raw material after heat treatment, so that the raw material can be extruded and heat formed in the mold.
