[0030] In summary:
[0031] Firstly, the operator places the injection molding part to be cut into the limiting frame 4. At this time, the second cylinder 16 is started, and the output shaft of the second cylinder 16 drives an arc-shaped clamp plate 17 to move, cooperating with another fixed arc-shaped clamp plate 17 to clamp and stabilize the injection molding part placed in the limiting frame 4. In this way, the injection molding part is firmly fixed in the limiting frame 4, ensuring that it will not move or shake during the subsequent cutting process. Next, the first cylinder 3 is started, and the output shaft of the first cylinder 3 is fixedly connected between the side plate 2 and one side of the limiting frame 4, so the start of the first cylinder 3 will drive the limiting frame 4 to move. The movement of the limiting frame 4 causes the gate part of the injection molding part to gradually move between the two cutting plates 5. When the gate part is completely located between the two cutting plates 5, the movement of the first cylinder 3 is stopped. At this time, the driving motor 11 is started, and the driving motor 11 drives the bidirectional screw 10 to rotate. The two ends of the bidirectional screw 10 are threadedly connected with the nut seat 12, so the rotation of the bidirectional screw 10 will drive the two nut seats 12 to move relative to each other. When the two nut seats 12 move, they respectively drive the sliding block 7 to slide in the sliding groove 8 and the sliding sleeve 13 to slide on the sliding rod 14. The cooperation of the sliding block 7 and the sliding groove 8, the sliding rod 14 and the sliding sleeve 13 provides guidance and support for the movement of the nut seat 12, ensuring the stability and accuracy of the movement of the nut seat 12. One side of the two nut seats 12 is fixedly connected with one side of the two connecting plates 15, so the movement of the nut seat 12 will drive the connecting plates 15 to move, and then drive the cutting plates 5 to move. The two cutting plates 5 move relative to each other to cut the gate of the injection molding part. After cutting, the first cylinder 3 is started again to move the limiting frame 4 backward, so that the gate of the injection molding part is aligned with the cleaning plate 6. The cleaning plate 6 is fixedly connected to one side of the cutting plate 5, so when the cutting plate 5 moves back and forth, the cleaning plate 6 will also move. By moving the cutting plate 5 back and forth, the cleaning plate 6 is driven to clean the cutting part of the gate, removing any residual plastic chips or burrs, ensuring the appearance and functionality of the injection molding part. Through the cooperation of the second cylinder 16 and the arc-shaped clamp plate 17, stable clamping of the injection molding part is achieved, ensuring that the injection molding part will not move or shake during the cutting process, improving the accuracy and consistency of the cutting, achieving the effect of improving the clamping stability and ensuring the cutting quality.
