The outer surface of each fixing column (310) is fixedly connected to a reinforcement ring (14), and the bottom end of each reinforcement ring (14) is fixedly connected to the top end of the movable disk (311).

10. A feeding method for a feeding device for producing high and low temperature resistant valve precision castings according to any one of claims 1 to 9, characterized in that: The specific steps include: S1: The telescopic end of the hydraulic cylinder (205) is caused to retract, thereby driving the fixed shell (207) and the material storage pipe (202) to move downward, thereby driving the sliding block (206) to slide in the slide groove (204), thereby causing the feeding pipe (201) to move downward, and then adding materials to the material storage pipe (202) through the feeding pipe (201). When the material is added, the telescopic end of the hydraulic cylinder (205) is caused to extend, driving the material storage pipe (202) to move upward. When it rises to an appropriate position, the electric telescopic end is caused to move upward. The telescopic end of the rod (208) contracts and moves, which can drive the movable plate (212) to move, thereby changing the position of the baffle (213), so that the material in the storage pipe (202) can be transported, and multiple materials can be added simultaneously through multiple feeding pipes (201), thereby facilitating the addition of materials. This can effectively avoid the need for workers to lift the materials before putting them into the tank, and materials can only be added through one feeding port. When multiple different raw materials or additives need to be transported at the same time, they can only be added sequentially, which can easily lead to the problem of reduced feeding efficiency of the device. S2: By rotating the output end of the driving motor (301), the first gear (305) is driven to rotate, thereby driving the two second gears (306) to rotate, and then driving the rotating disk (304) and the spiral stirring rod (309) to rotate, so that the various materials in the stirring tank (302) can be stirred, and the rotation of the second gear (306) can drive the fixed column (310) to rotate, and then drive the heating rod (312) on the movable disk (311) to rotate, thereby heating the various materials in the stirring tank (302) to achieve the purpose of sufficient mixing and stirring, and can effectively avoid the problem of uneven stirring of materials, resulting in reduced material quality.
