[0027] Embodiment 1

[0028] Please refer to Figures 1 - 3 As shown in the figure, the present utility model provides a technical solution: a silicon carbide-based refractory preform forming device, including: a stabilizing frame 1, a forming die 6, and an n-shaped frame 10;

[0029] The stabilizer 1 is a rectangular plate with support legs at the corners. A bearing plate 2 is fixedly connected to the top of the stabilizer 1. Guide slide rods 8 with limit blocks fixedly connected to the bottom are slidably connected to both the left and right ends of the bearing plate 2. Buffer springs 11 are sleeved on both the upper and lower ends of the outer surface of the guide slide rods 8. The buffer springs 11 are made of the same material and the number of buffer springs 11 is eight. The bottom of the forming die 6 is fixedly connected to the top of the guide slide rod 8. A positioning frame platform 13 is fixedly connected to the upper end of the outer surface of the forming die 6. A sealing gasket 16 is adhered to the top of the positioning frame platform 13. A vibration motor 12 is fixedly installed at the middle end of the bottom of the forming die 6. A through hole 15 is formed in the inner surface of the middle end of the bearing plate 2, and the outer diameter of the vibration motor 12 is smaller than the inner diameter of the through hole 15. The lower end inside the n-shaped frame 10 is fixedly connected to the upper end of the outer surface of the forming die 6. A threaded rod 14 is threadedly connected to the inner surface of the middle end of the top of the n-shaped frame 10. A rotating disk 9 is fixedly connected to the top of the threaded rod 14. The bottom of the threaded rod 14 is movably connected to a sealing cover 5 through a bearing. The sealing cover 5 moves inside the n-shaped frame 10, and the sealing cover 5 and the upper end of the forming die 6 are adapted to each other. Vacuum pump bodies 4 are fixedly installed at both the left and right ends of the top of the sealing cover 5, and the air inlet ends of the vacuum pump bodies 4 extend to the inside of the sealing cover 5 through pipes.

[0030] Through the setting of the stabilizer 1 in this technical solution, the stability of the device during use is ensured. Through the cooperation of the forming die 6, after injecting the required mud material into it, the rotating disk 9 drives the threaded rod 14 to rotate, and then drives the sealing cover 5 to slide downward inside the n-shaped frame 10.
