It should be noted that the cutter 24 may refer to a tool for cutting metal plates in the mold. The lower mold 4 is matched with the upper mold clamping plate 13. When in use, the metal plate is punched into an industrial wheel bottom plate through the forming components on the lower mold 4 and the upper mold clamping plate 13, but the excess metal plate will move to the bottom of the cutter 24, and the cutter 24 is driven to move toward the metal plate through the upper mold clamping plate 13, and the metal plate is cut by the cutter 24; a mounting groove 26 matched with the cutter 24 is opened at the removal of the upper mold clamping plate 13, which is used to The cutter 24 is inserted into the interior of the mounting groove 26, and the movement of the cutter 24 is limited by the mounting groove 26, and the cutter 24 is fixed to the interior of the mounting groove 26 by bolts; the cavity 276 is adapted to the movable block 273, so that the movable block 273 can slide inside the cavity 276 when in use, and the two ends of the push spring 274 are respectively fixedly connected to the inner wall of the movable block 273 and one side of the cavity 276, and the movable block 273 is pushed to one side of the block 271 by the push spring 274 when in use; in the cavity 2 A first through hole is provided on the inner wall on one side of cavity 276 for block 271 to pass through cavity 276. The horizontal longitudinal section of the first through hole is smaller than the horizontal longitudinal section of moving block 273, so that moving block 273 cannot pass through the first through hole to pass through cavity 276. Therefore, when moving block 273 moves to fit with the inner wall on one side of cavity 276, moving block 273 cannot continue to move due to the restriction of the inner wall on one side of cavity 276. A second through hole is provided on the inner wall on the front side of cavity 276 for pushing block 275 to pass through cavity 276, so that one end of pushing block 275 can pass through cavity 276. When the movable block 273 needs to be moved, the movable block 273 located inside the cavity 276 is driven to move by the pushing block 275 located outside the cavity 276; when one end of the set clamping block 271 is in contact with the inner wall of one side of the clamping groove 272, one end of the clamping block 271 is still located on the inner wall of the first through hole, and when the cutter 24 is inserted into the interior of the installation groove 26, the two clamping blocks 271 are respectively inserted into the interior of the clamping grooves 272 on both sides of the cutter 24, and the cutter 24 cannot be moved out of the installation groove 26 by pulling the clamping block 271.

Furthermore, when the position of the cutter 24 needs to be fixed, the moving block 273 and the clamping block 271 are first moved by the pushing block 275, so that the clamping block 271 moves out of the installation slot 26, and then the cutter 24 is moved into the interior of the installation slot 26, so that the clamping block 271 is aligned with the clamping slot 272, and the moving block 273 and the clamping block 271 are moved by the pushing spring 274, so that the clamping block 271 moves into the interior of the clamping slot 272, thereby restricting the cutter 24 to the interior of the installation slot 26, and finally the cutter 24 is pressed and fixed to the interior of the installation slot 26 by bolts, so that the cutter 24 cannot shake.
