[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] As shown in Figures 1-4, this utility model provides a technical solution:

[0021] An easy-to-clean injection molding machine includes a base 1. A mold box 2 and an injection molding machine body 3 are fixedly connected to the top of the base 1. A punch 4 is provided on one side of the mold box 2, and a die 5 is provided on one side of the injection molding machine body 3. A hopper 6 is provided on the top of the injection molding machine body 3, and a cleaning component is provided on the hopper 6. A cylindrical shell 7 is fixedly connected to the top of the injection molding machine body 3, and a lifting component is provided on the cylindrical shell 7. The hopper 6 and the injection molding machine body 3 adopt a separate design. The lifting component can drive the hopper 6 to rise a certain distance first, so that the hopper 6 and the injection molding machine body 3 are separated, and then drive the hopper 6 to rotate a certain angle. The cleaning component can clean the inner wall of the hopper 6.

[0022] The cleaning assembly includes a connecting plate 8, which is fixedly connected to the inner wall of the hopper 6. A servo motor 9 is fixedly connected to the top of the connecting plate 8. The output end of the servo motor 9 passes through the connecting plate 8 and is rotatably connected to it. A rotating shaft 10 is coaxially fixedly connected to the output end of the servo motor 9. A rotating rod 11 is coaxially fixedly connected to the bottom of the rotating shaft 10. Scraper strips 12 are fixedly connected to both ends of the rotating rod 11. When the servo motor 9 is started, the output end of the servo motor 9 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the scraper strips 12 to rotate through the rotating rod 11. The scraper strips 12 are tightly attached to the inner wall of the hopper 6, with no dead corners, and can thoroughly remove waste materials, realizing automated cleaning and saving manpower and time costs. When the injection molding machine is working, the rotation of the rotating rod 11 and the scraper strips 12 can also prevent the hopper 6 from clogging.

[0023] The lifting assembly includes a disc 13, which is fixedly connected to the inner wall of a cylindrical shell 7. A threaded rod 14 is rotatably connected to the disc 13. A bevel gear 15 is coaxially fixedly connected to the bottom of the threaded rod 14. A nut 16 is threaded onto the threaded rod 14. A connecting post 17 is fixedly connected to the outer periphery of the nut 16. A collar 18 is fixedly connected to one end of the connecting post 17. A connecting block 19 is fixedly connected to the outer periphery of the collar 18. One end of the connecting block 19 is fixedly connected to the hopper 6. An L-shaped through slot 20 is provided on the cylindrical shell 7, which is adapted to the connecting post 17. The bevel gear 15... The threaded rod 14 rotates on the disc 13, causing the nut 16 to rise. The nut 16 then drives the collar 18 to rise via the connecting column 17. The collar 18 then drives the hopper 6 to rise via the connecting block 19. The connecting column 17 rises vertically along the L-shaped through groove 20. When the connecting column 17 rises to the corner of the L-shaped through groove 20, the threaded rod 14 drives the nut 16 to rotate at one end, causing the connecting column 17 to rotate laterally along the L-shaped through groove 20. The connecting column 17 then drives the collar 18 to rotate at a certain angle, and the collar 18 then drives the hopper 6 to rotate at a certain angle via the connecting block 19.

[0024] The top of the injection molding machine body 3 is fixedly connected to a mounting base 21. A servo motor 22 is fixedly connected to the top of the mounting base 21. The output end of the servo motor 22 passes through the cylindrical shell 7 and is rotatably connected to it. A bevel gear 23 is fixedly connected to the output end of the servo motor 22 on the same axis. The bevel gear 23 meshes with the bevel gear 15. When the servo motor 22 is started, the output end of the servo motor 22 drives the bevel gear 23 to rotate, and the bevel gear 23 drives the bevel gear 15 that meshes with it to rotate.

[0025] The working principle of this utility model is as follows:

[0026] First, start the servo motor 22. The output of the servo motor 22 drives the bevel gear 23 to rotate. The bevel gear 23 drives the bevel gear 15 that meshes with it to rotate. The bevel gear 15 drives the threaded rod 14 to rotate on the disc 13. The threaded rod 14 drives the nut 16 to rise. The nut 16 drives the collar 18 to rise through the connecting column 17. The collar 18 drives the hopper 6 to rise through the connecting block 19, so that the hopper 6 is separated from the injection molding machine body 3. The connecting column 17 rises vertically along the L-shaped through groove 20. When the connecting column 17 rises to the corner of the L-shaped through groove 20, the threaded rod 14 drives the nut 16 to rotate at one end, so that the connecting column 17 rotates laterally along the L-shaped through groove 20. The connecting column 17 drives the collar 18 to rotate at a certain angle. The collar 18 drives the hopper 6 to rotate at a certain angle through the connecting block 19, so that the waste material from cleaning the hopper 6 falls to the side, effectively preventing waste material from falling into the injection molding machine and avoiding product quality problems caused by waste material mixing.

[0027] Then, servo motor 9 is started. The output of servo motor 9 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the scraper 12 to rotate through the rotating rod 11. The scraper 12 is in close contact with the inner wall of the hopper 6, with no dead corners for cleaning. It can completely remove waste materials, realize automated cleaning, and save manpower and time costs. When the injection molding machine is working, the rotation of the rotating rod 11 and the scraper 12 can also prevent the hopper 6 from getting blocked.

[0028] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
