The screw rod 23 is limited by the limiting rod 24 and the guide opening 22, so that the screw rod 23 rotates up and down with the rotary drum 21. The fan plate 25 at the upper part of the screw rod 23 is driven to move up and down, and the fan plate 25 will shake up and down after being moved up and down. When the rotary drum 21 rotates, the gas generated in the rotary drum 21 will be transported to the gas storage tank 67 through the connecting pipe 69. The valves on the connecting pipe 69 and the connecting pipe 68 are one-way valves. The bidirectional motor 20 drives the output shaft 60 to rotate, and the output shaft 60 drives the disc 61 to rotate. The disc 61 drives the eccentrically connected universal joint 62 on the bottom surface to rotate, and the universal joint 62 pulls the second horizontal plate 63, and the second horizontal plate 63 slides up and down on the guide rod 64, further driving the piston plate 66 to compress in the cavity column 19. The compression power generated inside will transmit the gas to the second cylinder 54. When the driving force of the second cylinder 54 is insufficient, a certain auxiliary effect can be provided. A part of the gas at the lower part of the cavity column 19 is compressed and pushed out upward from the exhaust port 70 on the piston plate 66, and the pushed-out gas enters the gas storage tank 67 through the connecting pipe 69.

[0029] In addition, when the cold gas injected into the shell 1 cools the formed casting, the first cylinder 26 and the first gas rod 27 are driven to produce telescopic movement, the lifting plate 28 is pulled upward by the first gas rod 27, the upper mold plate 8 and the lower mold plate 7 are separated, and then a part of the cold gas flowing in the first gas pipe 16 enters the gas storage tank 67 through the connecting pipe 68. The cold gas stored in the gas storage tank 67 is introduced into the gas inflation bag through the connecting pipe 3, and the cold gas is inflated into the gas inflation bag. The formed casting is ejected from the lower mold plate 7 after the gas inflation bag expands. At this time, the door plate is opened, and the door plate is arranged on the side of the shell 1 close to the mold plate. After the door plate is opened, the ejected casting is taken out.

[0030] Through the above specific embodiments, the skilled in the art can easily implement the present application. However, it should be understood that the present application is not limited to the above specific embodiments. On the basis of the disclosed embodiments, the skilled in the art can arbitrarily combine different technical features to realize different technical solutions.
