When the molding component 31 revolves, the second gear ring 3121 is meshed with the first arc-shaped rack 4 gear, so that the second base 3123 rotates 90 degrees, thereby moving the two ends of the adjustment plate 313 from the vertical groove of the L-shaped groove 34 to the horizontal groove, locking the height of the molding component 31, and the inner support seat 311 includes a first base 3112, and a plurality of knocking grooves 3113 are spaced apart on the outer wall of the first base 3112.

[0033] It should be noted that the position of the sliding hole 332 corresponds to the transverse groove of the L-shaped groove 34 , and the thickness of the sliding hole 332 is equal to that of the adjustment plate 313 .

[0034] Principle: Adjust the adjustment plate 313 to both ends are located in the vertical groove of the L-shaped groove 34, place the mold inside the first base 3112, and the electric push rod 22 drives the unloading end 23 to move to fit with the upper end of the mold, and feed the material into the mold through the unloading end 23. When feeding, the electric push rod 22 pushes the mold to vibrate up and down through the unloading end 23, so as to level the material in the mold, and the mold compresses the elastic component 314 along the inner wall of the mounting groove 35 through the inner support seat 311, the outer support seat 312 and the adjustment plate 313, and the L-shaped groove 34 vertical groove limits the two ends of the adjustment plate 313 to avoid deflection during vibration. After the feeding is completed, the electric push rod 22 drives the unloading end 23 to lift up, and the compressed elastic component 314 pushes the adjustment plate 313 to move to the top of the L-shaped groove 34 vertical groove, and the driving motor 36 drives the plate 32 to rotate, so that the molding component 31 revolves. First, The second gear ring 3121 is meshed with the first arc-shaped rack 4 gear, so that the second base 3123 rotates 90 degrees. At this time, the two ends of the adjustment plate 313 slide through the sliding hole 332 to the L-shaped groove 34 horizontal groove, locking the height of the outer support seat 312. Then the first gear ring 3111 is meshed with the second arc-shaped rack 5 gear to make the first base 3112 rotate. When the first base 3112 rotates, the knocking piece 3122 cooperates with the knocking groove 3113 to knock the first base 3112, thereby exhausting the raw material in the mold. When the molding component 31 revolves to the area where the first gear ring 3111 is out of mesh with the second arc-shaped rack 5, the loading is completed, and then the mold is pressurized and molded by an external pressurizing component to complete the molding of the ceramic insulator. The remaining molding components 31 are loaded by the electric push rod 22, and the assembly line operation of loading, leveling and exhausting can be realized.
