The sliding extrusion block 427 is gradually raised along the fixed frame 426 under pressure, and the sliding extrusion block 427 squeezes the extrusion head 425, and the extrusion head 425 gradually moves away from the fixed frame 426. , and drives the connecting rod 424 to move, the connecting rod 424 drives the first pull rod 422 to move, and stretches the second spring 423, the movement of the first pull rod 422 drives the push rod 4210 to move, the push rod 4210 slides along the second support rod 4211, and squeezes the connecting head 4212, at this time, the two connecting heads 4212 gradually deflect, so that the lower pressing block 4214 presses the synchronous pushing plate 413 at the bottom, and the synchronous pushing plate 413 at the bottom drives the unloading block 412 to squeeze the keycap, so that the keycap is separated from the forming groove 411, so as to facilitate unloading, and after the sliding extrusion block 427 is separated from the extrusion head 425, the sliding extrusion block 427 is at the top of the extrusion head 425, and the third spring 428 continues to squeeze the limit plate 429, and the limit plate 429 is pressed against the fixing frame 4 26, so that the sliding extrusion block 427 can be positioned on the outer wall of the fixing frame 426, and the second spring 423 drives the first pull rod 422 back to its original position, and the synchronous push plate 413 returns to its original position through the pulling force of the first spring 414. During this period, the staff can add material to the molding groove 411 on the other side to perform molding work again, thereby realizing continuous work, without the need to collect the keycaps separately, thereby improving work efficiency. When the molding of the other side is completed, the second support plate 43 is separated from the lower mold 41, the second cylinder 31 drives the lifting rod 33 to shrink, and the first rack 34 is meshed with the first gear 417 again, so that the lower mold 41 is flipped 180 degrees again, and the lifting rod 33 is squeezed downward, and the push block 35 at the top pressurizes the sliding extrusion block 427.The sliding extrusion block 427 moves downward to pressurize the extrusion head 425, so that the extrusion head 425 is extruded again, and the lower pressing block 4214 extrudes the synchronous push plate 413 again. Therefore, continuous unloading can be achieved by lifting and lowering the lifting rod 33, and the keycap is separated from the molding groove 411 and collected in the collection box 12.
