The side wall of the slide rail 8 is fixedly connected with a moving motor 9. The output end of the moving motor 9 is fixedly connected with a threaded rod 10. The threaded rod 10 penetrates through the slide rail 8 and is rotatably connected therewith. The outer wall of the threaded rod 10 is sleeved with a slider 11 threadedly connected thereto. The slider 11 is slidably connected with the slide rail 8. The bottom of the slide rail 8 is provided with a sliding groove. The slider 11 is located in the sliding groove and is slidably connected with its inner wall. The bottom of the slider 11 is fixedly connected with a hydraulic rod 12. The bottom of the hydraulic rod 12 is fixedly connected with a lifting plate 13. Multiple pump suction mechanisms are provided on the lifting plate 13.

[0025] It should be noted that: the workpiece products can be adsorbed and limited by the pump suction mechanism to ensure the stability during conveying and blanking.

[0026] The pump suction mechanism includes a vacuum generator 14 fixedly connected to the top of the lifting plate 13.

The vacuum suction nozzles 15 are provided in four, and the positions of the four vacuum suction nozzles 15 are distributed in a rectangular shape.

[0027] It should be noted that: the moving motor 9 can drive multiple vacuum suction nozzles 15 to move, so as to suck the injection-molded product from the injection molding machine body 2 and move it to the conveyor belt 5 to complete the blanking.
