[0025] The mold frame 9 is located below the discharge port 7, and a lower mold base 10 is provided at the lower end of the mold frame 9. A limiting groove 11 is provided inside the lower surface of the mold frame 9, and a limiting plate 12 is passed through the inside of the limiting groove 11, and the limiting plate 12 is welded to the upper surface of the lower mold base 10. In the device, a limiting plate 12 and a limiting groove 11 are provided at the connection between the mold frame 9 and the lower mold base 10. The sealing of the connection between the mold frame 9 and the lower mold base 10 is enhanced through the mutual cooperation of the limiting plate 12 and the limiting groove 11, and the leakage of concrete from the connection between the mold frame 9 and the lower mold base 10 is reduced. Probability, the left and right sides of the lower mold base 10 are both installed with a fixing plate 13, the lower surface of the lower mold base 10 is installed with a vibrator 24, the upper end of the fixing plate 13 is welded with a supporting plate 14, and the right side of the supporting plate 14 is installed with a controller 16, and the top plate 15 is welded to the top of the supporting plate 14.
