[0024] The top of the molding machine body 1 is provided with a powder pressing lower die table 4 between two conveyor belts 3, and the two conveyor belts 3 can convey the powder to the powder pressing lower die table 4;

[0025] Positioning blocks 5 are installed on both sides of the outer wall of the powder pressing lower die table 4, and supporting blocks 6 are installed on both sides of the inner wall of the molding machine body 1. The positioning blocks 5 and the supporting blocks 6 are slidably connected, and the positioning blocks 5 can slide up and down in contact with the outer wall of the supporting blocks 6;

[0027] A discharge rod 13 is installed at the top of the molding machine body 1, and the end of the discharge rod 13 is arranged in the discharge hole. The discharge rod 13 is fixed and can be raised and lowered under the powder pressing die table 4 to eject the molded powder in the discharge hole.

[0028] The side wall of the positioning block 5 is provided with a slide groove 16, the inner wall of the slide groove 16 is installed with a slide rail 17, a slider 14 is installed in the slide rail 17, the slider 14 is connected to the supporting block 6, and a buffer assembly 15 is assembled between the slider 14 and the inner wall at the top of the slide groove 16, so as to realize the sliding of the positioning block 5 on the outer wall of the supporting block 6.

[0029] The sliding buffer assembly 15 includes a fixed top plate 151, a fixed bottom plate 154 and a telescopic rod 152. The telescopic rod 152 is assembled between the fixed top plate 151 and the fixed bottom plate 154. A spring 153 is sleeved on the outside of the telescopic rod 152. The fixed top plate 151 is connected to the top inner wall of the slide groove 16, and the fixed bottom plate 154 is connected to the slider 14. The sliding of the slider 14 is achieved by the extension and retraction of the telescopic rod 152, and it is rebounded by the spring 153.

[0030] The outer walls on both sides of the fixed bottom plate 154 are both installed with balance rods 19, and the outer walls on both sides of the fixed top plate 151 are provided with balance cavities 18. The balance rods 19 are inserted into the balance cavities 18, and a balance plate 20 is installed on the top of the balance rods 19. The balance plate 20 is arranged in the balance cavity 18.

The bottom end of the lifting frame 9 is equipped with a pressing upper mold 7, and the positions of the pressing upper mold 7 and the pressing lower mold 12 correspond one to one.

[0033] Working process and principle: When in use, first, the powder is conveyed to the powder pressing lower die table 4 through the conveyor belt 3 on one side, and then the pressing upper die 7 is driven downward by the hydraulic cylinder 8 to cooperate with the pressing lower die 12 to press the powder into shape. When pressing down, the powder pressing lower die table 4 is forced to move downward. After pressing, the pressing upper die 7 moves upward. At this time, the powder pressing lower die table 4 returns to its original position, and the molding powder in the discharge hole is ejected by the discharge rod 13, and then the molding powder is pushed to the conveyor belt 3 on the other side by the discharge push rod 10.
