[0019] A guide groove 21 is formed on the inner side of the support frame 11 , and a clamping plate 20 is fixedly mounted on one end of the square frame 17 away from the lifting block 16 . One end of the clamping plate 20 is slidably inserted into the inner side of the guide groove 21 .

[0020] By adopting the above technical solution, the square frame 17 is guided by setting the clamping plate 20 to slide in the guide groove 21, and the clamping plate 20 and the lifting block 16 are limited by the diameter of the guide groove 21.

[0021] Symmetrically distributed clamping blocks 22 are slidably mounted on the inner side of the guide groove 21 , and springs 23 are fixedly mounted on opposite ends of the clamping blocks 22 . The top surface of the clamping block 22 at the top is in contact with the bottom surface of the clamping plate 20 .

[0022] By adopting the above technical solution, the springs 23 are arranged between the clamping blocks 22 to provide auxiliary support for the clamping plate 20, thereby improving the stability of the square frame 17.

[0029] Working principle: First, the injection material is put into the lower mold 12, and then the cylinder 13 is driven to push the upper mold 14 to move downward. The upper mold 14 moves downward and contacts the lower mold 12 to inject the material. If burr waste overflows during the injection molding process, the lifting motor 19 is driven to rotate the lifting screw 15. The lifting screw 15 rotates to drive the lifting block 16 to move downward. The lifting block 16 moves downward to drive the square frame 17 to move downward. The square frame 17 drives the scraper 18 to move. The card plate 20 slides in the guide groove 21 to guide the square frame 17. The diameter of the guide groove 21 is used to limit the card plate 20 and the lifting block 16. The spring 23 between the card blocks 22 is used to assist the support of the card plate 20, thereby improving the stability of the square frame 17. The scraper 18 moves downward to cut and scrape the overflowed waste, thereby realizing the removal of burr waste from the plastic bag, improving the production quality of the plastic bag, and the structure is ingenious and convenient to use.
