The support bar 9 can support the lower mold 202, thereby preventing the lower mold 202 from squeezing the condensation tube 206. The suction force provided by the liquid extraction pump 204 can be used to extract the coolant in the condensation tank 203, so that the coolant is directly transported to the condensation tube 206 through the guidance of the infusion hose 205. In the embodiment, the condenser 206 can conduct heat between the coolant and the casting mold in the lower mold 202, so that the valve mold in the lower mold 202 can be quickly cooled down. The coolant after cooling the casting mold is guided by the return hose 207 and re-enters the condenser box 203, so that the water circulation radiator and cooling fan inside the condenser box 203 can quickly cool down the entering coolant, thereby realizing the recycling of the coolant, making it convenient to quickly cool and shape the cast valve during valve production, thereby reducing the valve casting time. The movable frame 305 can support the limit frame 201 during casting. After the valve is cooled and formed, the elasticity provided by the electric telescopic rod 304 can drive the movable frame 305 to move downward, so that the movable frame 305 can release the limit of the limit frame 201, and the power provided by the stepping motor 301 can drive the connecting frame 302 to rotate, and the bearing 303 can facilitate the rotation of the connecting frame 302, thereby driving the limit frame 201 to rotate inside the support frame 1, so that the cooled and formed valve can slide out of the lower mold 202 by gravity, and the staff can knock the rubber pad 307 to knock the molded valve off, and the rubber pad 307 can facilitate the staff to knock the limit frame 201 The limit frame 201 is protected when struck, and the sliding molded valve can fall onto the guide frame 306. The molded valve can be guided out through the guide frame 306, so as to facilitate the automatic and rapid demoulding of the molded valve, thereby reducing the labor intensity of the staff and improving the production efficiency of the valve. The universal wheel 11 can be limited and fixed by the connecting plate 10, so that the device can be moved through the universal wheel 11, so as to facilitate the adjustment of the valve casting position. Manually holding the handle 15 can drive the threaded rod 12 to rotate, so that the grounding plate 13 can drive the anti-slip pad 14 to contact the ground, thereby increasing the stability of the device during operation.
