[0002] Silicon balls are spherical bodies formed by pressing industrial silicon powder, additives and binders through a high-pressure pair-roll briquetting machine.

[0003] A preparation mechanism for pressing ferrosilicon manganese balls with the publication number CN219900243U includes a bottom plate, and a lower mold is movably attached to the top of the bottom plate. For this preparation mechanism for pressing ferrosilicon manganese balls, by rotating the T-shaped rod, the T-shaped rod will drive the gear to rotate, and the gear drives the racks on both sides to move, and then cooperate with the annular frame to achieve the effect of restricting the movement of the lower mold, and it is convenient to take out the lower mold, achieving the effect of conveniently taking out the ferrosilicon manganese balls.

[0004] When the above-mentioned preparation mechanism for pressing is actually used, after the upper mold and the lower mold are closed, there is a lack of a sealing mechanism at the closed connection, resulting in insufficient airtightness of the internal chamber formed after the combination of the upper mold and the lower mold, thus affecting the high-pressure forming processing effect of silicon balls.

[0028] An upper mold 6 is fixedly installed on the lower surface of the movable plate 5, and a sealing assembly 7 is fixedly arranged on the upper surface of the movable plate 5.

[0035] The surface of the flow splitting box 701 is fixedly embedded with a first air duct 703 and a second air duct 704.

[0041] Working principle: After the hydraulic cylinder 4 drives the lower die 10 at the bottom of the movable plate 5 into the inner part of the lower die limit seat 8, it simultaneously drives the frame-shaped baffle 705 to cover and seal the lower die limit seat 8. Then, the air pump 702 is used to transport gas into the shunt box 701. Furthermore, the gas is transported to the inside of the first sealing air cushion 706 and the second sealing air cushion 707 on the inner wall of the frame-shaped baffle 705 through the first air duct 703 and the second air duct 704 on the surface of the shunt box 701, so that the first sealing air cushion 706 and the second sealing air cushion 707 fill the first strip-shaped grooves 13 and the second strip-shaped grooves 14 on the surfaces of the first sealing strip 11 and the second sealing strip 12 after expansion, keeping the space between the inner wall of the frame-shaped baffle 705 and the lower die limit seat 8 in a sealed state, thereby improving the airtightness between the upper die 6 and the lower die 10 and being conducive to the high-pressure forming process of silicon balls.
