[0026] In this embodiment, a vacuum sensor 20 is fixedly connected to the inside of the pouring tank body 1, which is convenient for monitoring the vacuum degree inside the pouring tank body 1. A vacuum pump 10 is fixedly connected to the rear side of the pouring tank body 1. The input end of the vacuum pump 10 is fixedly connected to an exhaust pipe 11, and the output end of the vacuum pump 10 is fixedly connected to an exhaust pipe 12.

[0027] Among them, a balancing component for maintaining a stable vacuum is arranged inside the casting tank body 1, and the balancing component includes an air duct 14 fixedly connected to the inside of the casting tank body 1 and connected to the exhaust pipe 12, and the other end of the air duct 14 is fixedly connected to a vacuum regulating valve 15 extending into the casting tank body 1, so that the vacuum regulating valve 15 cooperates with the air duct 14 to balance the stability of the vacuum in the casting tank body 1.

[0028] In this embodiment, the casting tank body 1 is slidably connected to a casting mold 19, and the casting tank body 1 is fixedly connected to a casting pipe 16.

[0035] When the vacuum degree in the casting tank body 1 reaches a preset value, the feed gate valve 3 in the corresponding feed pipe 2 can be opened to allow the two materials to enter the casting tank body 1, and the mixing effect of the materials can be maintained by the rotation of the stirring frame 8. After the mixing is completed, the vacuum degree in the casting tank body 1 can be adjusted again to the mixing condition of the other material, and the feed gate valve 3 in the corresponding feed pipe 2 can be opened when the vacuum degree meets the requirements to realize the feeding. During the feeding process, there is no need to open the feed pipe 2, and the casting tank body 1 is always in a closed state, which can avoid the trouble of repeatedly adjusting the vacuum degree and improve work efficiency.
