[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are classified as vertical, horizontal, and all-electric. Injection molding machines heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity.

[0003] When using existing injection molding machine feeding mechanisms, hygroscopic plastic materials tend to clump together. However, these clumps can easily cause blockages and uneven plasticization inside the feed inlet. Therefore, it is necessary to provide a new injection molding machine feeding mechanism to solve the above-mentioned technical problems. Utility Model Content

The new feeding mechanism further includes a feeding mechanism 4 with a connecting block 401 fixedly connected to the first conical groove 2. A feeding cylinder 402 is fixedly connected to the middle of the connecting block 401. A first motor 403 is mounted on the upper end of the feeding cylinder 402. A rotating rod 404 is connected to the power output end of the first motor 403. The outer surface of the rotating rod 404 is connected to... The feeding cylinder 402 has a spiral blade 405 that fits against the inner wall of the feeding cylinder 402. A discharge port 406 is provided at the bottom of the upper end of the feeding cylinder 402. The screening mechanism 7 includes a screening plate 701 inclinedly placed inside the hopper 1. Guide plates 702 are fixedly connected to the front and rear ends of the upper surface of the screening plate 701. A connecting seat 703 is installed in the middle of the bottom of the guide plate 702. A vibrating motor 704 is installed at the bottom of the connecting seat 703. Fixing bolts 705 are inserted into the four corners of the upper surface of the connecting seat 703.

Through pulley 904 and belt 905, the two sets of rotating shafts 902 rotate synchronously, which facilitates the crushing of the lumpy hygroscopic plastic that has been screened into the crushing box 8. After crushing, the plastic is screened and discharged through the filter screen 12 to avoid clogging of the feed inlet 5 and to ensure uniform feeding of the device, thus avoiding uneven plasticization after feeding. At the same time as screening and crushing, the first motor 403 is turned on to drive the spiral blade 405 on the rotating rod 404 to rotate, so that the material entering the feeding cylinder 402 through the feed inlet 5 is conveyed by water, ensuring the effectiveness of feeding of the device.
