[0029] Reference Figure 1 and Figure 2 and Figure 3 As shown, the clamping block 2 is symmetrically provided with a slide groove 3 inside, and an auxiliary clamping clamping assembly 4 is arranged inside the slide groove 3. The clamping assembly 4 includes a slider 51 slidably arranged in the slide groove 3, a guide rod 7 is installed in the slide groove 3, and the slider 51 is sleeved and installed on the guide rod 7.

The center of the clamping block 2 is disc-shaped.

[0030] By setting the clamping assembly 4, the rotating rod 101 is rotated. During the rotation of the rotating rod 101, the meshing gear 9 is driven to rotate, and the meshing tooth plate 8 is meshed with the meshing gear 9, so that the meshing tooth plate 8 moves. During the movement of the meshing tooth plate 8, the slider 51 is driven to move, so that the slider 51 drives the sliding block 5 to move as a whole, and when the two sliding blocks 5 move toward the center of the clamping block 2, the injection molded parts are driven to be clamped, which can facilitate the stable clamping of injection molded parts of different sizes during work, and meet the clamping requirements of injection molded parts of different sizes.

When working, place the injection molded part to be processed at the center of the clamping block 2, and rotate the rotating rod 101. During the rotation of the rotating rod 101, the meshing gear 9 is driven to rotate, and the meshing gear plate 8 and the meshing gear plate 8 are engaged. The meshing gears 9 are meshed with each other to move the meshing tooth plate 8, and in the process of the meshing tooth plate 8 moving, the slider 51 is driven to move, so that the slider 51 drives the sliding block 5 to move as a whole, and when the two sliding blocks 5 move toward the center of the clamping block 2, the injection molded parts are driven to be clamped, and after the rotating rod 101 moves to the clamping, the overall positioning of the rotating rod 101 is completed by inserting the positioning block 12 in the positioning groove 21, and after clamping, the clamping block 2 can be pushed, so that the clamping block 2 slides along the guide rail 1 to the corresponding processing station for processing.

[0037] During operation, when the rotating rod 101 needs to be disassembled, the slide plate 15 is pulled, and the slide plate 15 drives the connecting belt 11 to be pulled as a whole. In the process of the connecting belt 11 being pulled, the positioning block 12 is driven to move as a whole, and in the process of the positioning block 12 moving, the ejection spring 13 is driven to be compressed as a whole. At this time, the rotating rod 101 can be reversed to remove the clamped injection molded part.
