A drive plate 14 is fixedly connected to the bottom surface of the mold 2 on the left side, with one end passing through the drive groove 15 and extending to the bottom of the placement plate 1. A screw 17 is fixedly connected to the output shaft of the drive motor 16, with one end passing through the drive plate 14 and extending to the connecting plate 4. The screw 17 is rotatably connected to the connecting plate 4 through a bearing.

[0032] The drive plate 14 and the drive groove 15 are slidably connected. The left side of the drive plate 14 has a threaded hole, and the screw 17 passes through the threaded hole and is threadedly connected to it.

[0033] Specifically, the drive motor 16 is started, and the output shaft of the drive motor 16 drives the screw 17 to rotate. Through the threaded connection between the screw 17 and the drive plate 14 and the sliding connection between the drive plate 14 and the drive groove 15, the screw 17 drives the left mold 2 to move to the left through the drive plate 14.

[0034] Please see Figures 1 to 3 In this embodiment, a collection assembly for collecting handles is provided between the two support plates 3. The collection assembly includes a collection chamber 5, which is placed at the bottom of the placement plate 1. A limiting groove 23 is provided on the front of the connecting plate 4. A limiting block 22 with one end extending into the limiting groove 23 is fixedly connected to the top surface of the collection chamber 5. Two positioning grooves 21 are provided on the front of the support plate 3 on the right side. Two positioning plates 19 with one end extending into the two positioning grooves 21 are fixedly connected to the right side of the collection chamber 5. Rubber pads 20 are fixedly connected to the top and bottom surfaces of the two positioning plates 19. A guide plate 18 is fixedly connected inside the collection chamber 5.

The positioning plate 19 and the positioning groove 21 are slidably connected. The rubber pad 20 and the positioning groove 21 are attached.

[0036] Specifically, when the collection bin 5 is pushed, the limiting block 22 is inserted into the limiting groove 23, and the positioning plate 19 is inserted into the positioning groove 21. Through the sliding connection between the limiting block 22 and the limiting groove 23, and the sliding connection between the positioning plate 19 and the positioning groove 21, the collection bin 5 is fixed on the support plate 3. The positioning plate 19 is supported by the fit between the rubber pad 20 and the positioning groove 21, which improves the stability of the positioning plate 19. The handle passes through the discharge groove 13 and enters the collection bin 5. The collection bin 5 collects the handle.

[0037] The working principle of the above embodiments is as follows:

[0038] The collection bin 5 is pushed forward, the limiting block 22 is inserted into the limiting groove 23, and the positioning plate 19 is inserted into the positioning groove 21. Through the sliding connection between the limiting block 22 and the limiting groove 23, and the sliding connection between the positioning plate 19 and the positioning groove 21, the collection bin 5 is fixed on the support plate 3. The positioning plate 19 is supported by the fit between the rubber pad 20 and the positioning groove 21, improving the stability of the positioning plate 19. The raw material enters the forming cavity 11 through the feed hole 10. The raw material is shaped by the forming cavity 11. After the handle is formed, the drive motor 16 is started, and the output shaft of the drive motor 16... The screw 17 is rotated, and through the threaded connection between the screw 17 and the drive plate 14 and the sliding connection between the drive plate 14 and the drive groove 15, the screw 17 drives the left mold 2 to move to the left through the drive plate 14, thereby activating the electric push rod 6. The output end of the electric push rod 6 drives the push plate 12 to move, and the push plate 12 pushes the handle away from the molding cavity 11. The sliding connection between the sliding plate 9 and the sliding groove 8 supports the push plate 12, improving the stability of the push plate 12. The handle passes through the discharge groove 13 and enters the interior of the collection chamber 5, where the handle is collected.
