[0002] With the rapid development of the smartphone market, mobile phone cases, as one of the important accessories, continue to see growing demand. To meet diverse market demands, injection molding technology is required to manufacture different models of mobile phone cases during production. However, in actual production, it has been found that after each injection molding operation, uncured raw materials or fine particles are likely to remain on the mold surface. If these residual materials are not removed in a timely manner, they will directly affect the quality and appearance of subsequent products and may even lead to an increase in product defect rates. In the prior art, solutions to this problem mainly rely on manual cleaning or regular maintenance during production breaks. However, this approach is not only inefficient and increases labor costs, but also, for continuous production lines, frequent shutdowns can significantly reduce overall production efficiency.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] Example 1: An injection molding device for producing mobile phone protective cases, such as Figure 1-Figure 5 As shown, it includes a support frame 1, a processing table 2, a cover frame 3, an opening and closing door 31, a feeding pipe 4, a feeding hopper 5, a spiral feeding pipe 6, a driving motor 7, a fixed die 8, a sliding die 9, a hydraulic cylinder 10, a cleaning component and a collecting component. The front and rear parts of the lower side of the processing table 2 are fixedly connected to the support frame 1, the upper side of the processing table 2 is fixedly connected to the cover frame 3, the front side of the cover frame 3 is rotatably connected to the opening and closing door 31, the right part of the opening and closing door 31 is provided with a handle, the left part of the upper side of the processing table 2 is fixedly connected to the spiral feeding pipe 6, the middle part of the spiral feeding pipe 6 is connected to the feeding pipe 4, the upper side of the feeding pipe 4 is connected to the feeding hopper 5, and the feeding The bucket 5 is fixedly connected to the left part of the cover frame 3, the driving motor 7 is fixedly connected to the left part of the upper side of the processing table 2, the output shaft of the driving motor 7 is fixedly connected to the spiral shaft of the spiral feed pipe 6, the fixed mold 8 is fixedly connected to the middle part of the upper side of the processing table 2, the right end of the spiral feed pipe 6 is connected to the fixed mold 8, and the sliding mold 9 is slidably connected to the fixed mold 8. The hydraulic cylinder 10 is fixedly connected to the right part of the upper side of the processing table 2, and the telescopic end of the hydraulic cylinder 10 is fixedly connected to the sliding mold 9. A cleaning component for cleaning residual raw materials is provided on the fixed mold 8 and the cover frame 3, and a collecting component for collecting the cleaned raw materials is provided on the processing table 2.
[0020] When using this device, the staff controls the sliding mold 9 to slide to the left and close with the fixed mold 8 through the hydraulic cylinder 10, and then the staff guides the raw materials into the discharge pipe 4 through the discharge hopper 5, and then enters the spiral feed pipe 6 from the discharge pipe 4. The rotation of the output shaft of the drive motor 7 drives the spiral shaft of the spiral feed pipe 6 to rotate to transport the raw materials to the right, and then a certain amount of raw materials is injected into the fixed mold 8. The mobile phone protective cover is injection molded by the fixed mold 8 and the sliding mold 9. After the mobile phone protective cover is formed, the sliding mold 9 is controlled by the hydraulic cylinder 10 to slide to the right and open. After the sliding mold 9 slides to the right and opens, the cleaning component can clean the raw materials remaining on the fixed mold 8, and the collecting component can collect the cleaned raw materials. After the sliding mold 9 slides to the right and opens, the staff controls the opening and closing door 31 to slide forward and open, and then takes out the mobile phone protective cover formed in the sliding mold 9.
[0021] Example 2: Based on Example 1, Figure 1 、 Figure 3 and Figure 4 As shown, the cleaning assembly includes a guide plate 11, a cleaning plate 12, a guide wheel 13, a connecting rope 14 and an elastic member 15. The guide plate 11 is fixedly connected to the upper side of the fixed mold 8, and the cleaning plate 12 is slidably connected to the guide plate 11. The lower end of the cleaning plate 12 is a pointed cone for scraping off the residual raw materials. The middle and right parts of the cover frame 3 are rotatably connected to the guide wheels 13, and the upper side of the cleaning plate 12 is connected to the connecting rope 14. The tail end of the connecting rope 14 passes around the two guide wheels 13 in turn and is connected to the sliding mold 9. Two elastic members 15 are connected between the cleaning plate 12 and the guide plate 11.
[0022] When using this device, the sliding mold 9 slides to the left, pulling the cleaning plate 12 to slide upward through the connecting rope 14, and the elastic member 15 is deformed. After the cleaning plate 12 slides upward and is lifted, the sliding mold 9 can be normally closed with the fixed mold 8 for injection molding. When the mobile phone protective cover is formed, the sliding mold 9 slides to the right to open and the connecting rope 14 is loosened. Under the action of the resetting of the elastic member 15, the cleaning plate 12 slides downward to clean the residual raw material on the fixed mold 8, so as to prevent the residual raw material on the fixed mold 8 from affecting the quality of the next injection molding.
[0023] like Figure 1 and Figure 5 As shown, the collection component includes a mounting frame 16, a collection box 17 and an interception net 18.

[0024] When the device is used, the raw materials scraped downward by the cleaning plate 12 will leak from the interception net 18 and then fall into the collection box 17 for collection. After the sliding mold 9 slides to the right and opens, if the formed mobile phone protective case falls directly out of the sliding mold 9, it will be blocked by the interception net 18. When it is necessary to clean the raw materials in the collection box 17, the staff can control the collection box 17 to slide forward and pull it out.
