[0032] Referring to Figure 3 , Figure 4 and Figure 5The cleaning mechanism 2 includes a fixing block 201, which is fixedly connected to the top of the injection molding machine 1, and serves to support and fix related components. A cover plate 202 is rotatably connected to the front inner wall of the fixing block 201. The cover plate 202 can rotate around an axis through its rotatable connection with the front inner wall of the fixing block 201. The cover plate 202 engages with the injection cylinder 3, and the cover plate 202 protects the injection cylinder 3 and prevents external impurities from entering the injection cylinder 3. A motor 203 is fixedly connected to the top of the cover plate 202. When it is necessary to clean the injection cylinder 3, the motor 203 is started and begins to rotate. Its output end drives the connecting column 204 to rotate. Since the connecting post 204 is fixedly connected to the output end of the motor 203 and passes through the cover plate 202, the connecting post 204 will rotate synchronously with the motor 203. The output end of the motor 203 passes through the cover plate 202 and is fixedly connected to the connecting post 204. Scrapers 205 are fixedly connected to both the front and rear sides of the outer wall of the connecting post 204. As the connecting post 204 rotates, the scraper 205 will also make a circular motion. When the scraper 205 rotates, it will stick tightly to the inner wall of the injection cylinder 3 and scrape off the residual plastic material on the inner wall of the injection cylinder 3.
[0033] Reference Figure 2 , Figure 3 and Figure 5 Multiple support columns 11 are fixedly connected to the bottom of the outer wall of injection molding machine 1. Their main function is to support the injection molding machine, maintaining a certain distance between it and the ground. Foot pads 12 are fixedly connected to the bottom of each support column 11 to increase the stability of the injection molding machine in contact with the ground and to provide cushioning and anti-slip properties. A rotating plate 13 is installed at the bottom of the outer wall of injection molding machine 1. Hinges 14 are threadedly connected to the top left and right sides of the outer wall of the rotating plate 13. The rotating plate 13 is connected to the injection molding machine 1 via the hinges 14. The hinge 14 is a rotating connection. The threaded connection of the hinge 14 ensures the firmness of the connection and can withstand a certain weight and force. When the rotating plate 13 needs to be used, external force is applied to make the rotating plate 13 rotate around the axis of the hinge 14. The bottom of the outer wall of the rotating plate 13 is provided with a connecting groove 15. The inner wall of the connecting groove 15 is fixedly connected with a handle 16. When it is necessary to open or close the rotating plate 13, the operator can hold the handle 16 and apply appropriate force to make the rotating plate 13 rotate around the hinge 14.
[0034] Reference Figure 1 , Figure 3 and Figure 4A controller 17 is fixedly connected to the middle right side of the outer wall of the injection molding machine 1. The controller 17 is electrically connected to the motor 203. Since the controller 17 is electrically connected to the motor 203, the operator can send commands through the controller 17 to control the start, stop and speed parameters of the motor 203. A connecting piece 18 is fixedly connected to the rear side of the outer wall of the fixing block 201. The bottom of the connecting piece 18 is threaded to the top of the injection molding machine 1. This threaded connection provides a relatively firm connection, ensuring that the fixing block 201 will not easily shift during the operation of the injection molding machine. A connecting groove 29 is opened on the front side of the top of the cover plate 202. A handle 20 is fixedly connected to the inner wall of the connecting groove 219. When it is necessary to open the cover plate 202 to check the injection cylinder 3 or to perform cleaning operations, the operator can hold the handle 20 and pull upward to open the cover plate 202.
[0035] Working principle: Material is placed into injection cylinder 3, which serves as a storage container for the material, providing raw materials for injection molding. Upper mold 6 is suspended from the bottom of injection molding machine 1 by telescopic rod 5, and lower mold 7 is fixed to the top of fixed box 8, which is located at the top of injection molding machine 1. When injection is required, the telescopic rod 5 moves downward to engage upper mold 6 and lower mold 7. Material from injection cylinder 3 is then injected into upper mold 6 and lower mold 7 through connecting pipe 4. Heating box 9 at the bottom of the inner wall of injection molding machine 1 starts working. Heating element inside heating box 9 converts electrical energy into heat energy. This heat is conducted through heating pipe 10 to the rear of fixed box 8, and then to lower mold 7. The temperature of lower mold 7 gradually rises under the continuous heating of heating pipe 10, reaching a suitable temperature range for injection molding. Since lower mold 7 has been heated, the material can maintain good fluidity after entering the mold, better conforming to the shape of the mold cavity, thus ensuring the quality of the injection molded product.
[0036] Furthermore, it is securely connected to the top of the injection molding machine 1 via the fixing block 201, providing reliable support. The cover plate 202 is rotatably connected to the front side of the inner wall of the fixing block 201, allowing the cover plate 202 to rotate around the fixing block 201 and engage with the injection cylinder 3, effectively preventing external dust and debris from entering the injection cylinder 3, ensuring a relatively clean internal environment for the injection cylinder 3, and maintaining its normal function of storing and conveying injection molding materials. When the injection cylinder 3 has been used for a period of time and plastic raw materials remain on its inner wall, requiring cleaning, the operator starts the motor 203. The output end of the motor 203 drives the connecting column 204, which is fixedly connected to it and passes through the cover plate 202, to rotate synchronously. During the rotation of the connecting column 204, since the scraper 205 is fixedly connected to the front and rear sides of its outer wall, the scraper 205 also moves in a circular motion. The scraper 205 uses the friction between itself and the inner wall of the injection cylinder 3, as well as its own scraping action, to gradually scrape off the residual plastic raw materials adhering to the inner wall of the injection cylinder 3.
