The new type of powder pressing mold is provided with a limited position sleeve, a fixed column and a first hydraulic rod, so that they are used in conjunction with each other, so that when the powder pressing mold is pressed, the upper pressing mold in the mold can ensure stable pressing, so that the pressed powder block has a flat surface, fine texture, and ultra-high gloss three-dimensional relief shape, and the first hydraulic rod can realize automatic opening and closing of the upper pressing mold, which reduces the labor intensity of the staff.

[0004] However, in actual use, this structure can often only perform simple upper and lower limit positioning operations. However, in the overall upper and lower docking and pressing process, it is very easy for the powder to be unevenly stressed, and a more uniform pressed powder material cannot be obtained, which affects the final production quality. At the same time, the equipment cannot properly handle the excess powder pressed out during the powder pressing process and cannot meet daily use needs. Therefore, it is urgent to design a positioning auxiliary device for the powder pressing mold to solve the above problems. Utility Model Content

[0012] Preferably, a positioning rubber ring is arranged between the docking frames, and a powder suction grid is arranged inside the docking frames.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The positioning auxiliary device for the powder pressing mold can enable the equipment to perform more accurate and stable upper and lower pressing operations of the powder pressing mold throughout the entire process by arranging an upper pressing frame, a lower pressing frame, a mold groove, a magnetic side strip, a docking frame, a powder guide tube, an L-shaped positioning seat, an electric push rod, a positioning rubber pad and a positioning rubber ring. In actual use, the staff can install the upper and lower parts of the powder pressing mold to be used in the internal position of the mold groove through the magnetic side strips inside the upper pressing frame and the lower pressing frame respectively, and at this time, the electric push rods on the top of the L-shaped positioning seats on the four sides of the upper pressing frame and the lower pressing frame can be started. , so that the upper L-shaped positioning seat can drive the upper pressing frame, and accurately position the downward L-shaped positioning seat and the lower pressing frame for docking operation, so that the upper and lower parts of the powder pressing mold inside the upper and lower pressing frames can be quickly docked. At the same time, when the powder pressing mold is completely docked up and down, the positioning rubber pads between the L-shaped positioning seats are stably positioned and pressed, and the upper and lower pressing frames are quickly pressed and positioned through the positioning rubber rings at the outer edges of the docking frames, thereby ensuring that the upper and lower pressing frames can perform more firm and stable upper and lower powder pressing operations, reflecting the practicality of the equipment design.

[0015] The positioning auxiliary device for the powder pressing mold further improves the overall use effect of the equipment by arranging an upper pressing frame, a lower pressing frame, a material collecting frame, a pumping frame, a powder suction fan, a collecting trough, a conical suction seat, a powder isolation filter, a powder guide tube and a powder suction grid. In daily use, the staff can start the powder suction fan on the top of the pumping frame, and then the powder suction fan performs a suction operation on the inside of the upper pressing frame from the pumping frame. At this time, the powder guide tubes at the corners on both sides of the upper and lower groups of docking frames can make the powder suction grids inside the two groups of docking frames perform synchronous suction operations, thereby forming a stable suction annular wind wall structure at the edges of the upper and lower pressing frames, and quickly collecting the scattered powder pressed out of the upper and lower powder pressing molds. At the same time, the powder is finally concentrated from the inside of the pumping frame through the conical suction seat inside the collecting trough, and is properly collected under the barrier of the powder isolation filter, which reflects the comprehensiveness of the equipment design.
