[0002] A plastic injection molding machine, also known as an injection molding machine or plastic injection molding machine, is a main molding equipment that uses plastic molds to make various shapes of plastic products such as disposable plastic forks, plastic furniture, and plastic shells for various objects from thermoplastic or thermosetting materials.

[0003] Chinese Patent Publication No. CN216544394U discloses a plastic injection molding machine with high injection pressure and a small footprint. The machine includes: a base; a worktable fixedly mounted on the top of the base; a protective shell fixedly mounted on the top of the base and on one side of the worktable; and a side door rotatably mounted on the other side of the worktable via a hinge. A handle is fixedly mounted on the outside of the side door. This utility model provides a vertical plastic injection molding machine with high injection pressure and a small footprint, significantly reducing the floor space. Masterbatch is poured into a hopper and enters the interior of the outer shell. A motor drives a screw to rotate, causing the masterbatch to enter a heating cylinder for heating and melting, and finally extrusion. The screw rotation increases the injection pressure, while the outer cylinder provides insulation to prevent burns from direct contact with the user. The cooperation between the upper and lower mold components facilitates the replacement of different molds, improving production efficiency.

[0004] However, in the existing plastic injection molding machine described above, when the plastic raw material enters through the feed pipe, the molten plastic easily adheres to the inner wall of the feed pipe when the injection mechanism melts the plastic raw material, which can easily cause blockage of the feed pipe and affect the subsequent feeding of plastic raw material. Therefore, this utility model proposes a plastic injection molding machine to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a plastic injection molding machine to solve the problem that melted plastic easily adheres to the inner wall of the feed pipe, causing blockage of the feed pipe and affecting the feeding of plastic raw materials in the next operation.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0023] Example 1

[0024] This utility model provides, for example Figures 1-5 As shown, a plastic injection molding machine includes: an injection molding machine body 1, a feed pipe 2 on the surface of the injection molding machine body 1, a support plate 3 on the outer side of the feed pipe 2, a drive motor 4 on the surface of the support plate 3, a drive wheel 5 sleeved on the transmission end of the drive motor 4, a lifting groove 6 on the inner side of the feed pipe 2; a lifting screw 7, a lifting plate 8 screwed to the surface of the lifting screw 7, a first bearing 9 on the side of the lifting plate 8, a support rod 10 inside the first bearing 9, and a cleaning plate 12 at one end of the support rod 10;

[0025] First, the drive motor 4 can be started to rotate the lifting screw 7 in conjunction with the traction belt 15. This causes the lifting plate 8 to move upward in the lifting groove 6, which in turn causes the cleaning plate 12 to move upward in the feed pipe 2. This allows the cleaning plate 12 to scrape off the plastic adhering to the inner wall of the feed pipe 2, thus preventing the easy adhesion of melted plastic to the inner wall of the feed pipe 2, which could easily cause blockage and affect the next feeding of plastic raw materials.

[0026] Example 2: Figures 1-3As shown, a cleaning plate 12 is provided to facilitate cleaning of the inner wall of the feed pipe 2. A support plate 3 is fixedly connected to the outer side of the feed pipe 2. A protective cover 13 is provided on the surface of the support plate 3. The protective cover 13 covers the drive motor 4. A pulley 14 is sleeved on one end of the lifting screw 7. The pulley 14 and the drive wheel 5 are driven by a traction belt 15. A second bearing 16 is provided at the bottom of the lifting groove 6. One end of the lifting screw 7 is fixedly connected to the inner ring surface of the second bearing 16. The first bearing 9 is fixedly connected to the side of the lifting plate 8.

[0027] More specifically, the drive motor 4 can first be protected by the protective cover 13. Then, the drive motor 4 can be started to drive the drive wheel 5 to rotate, which will cause the pulley 14 of the traction belt 15 to rotate, thereby causing the lifting screw 7 to rotate. This will cause the lifting plate 8 to move upward in the lifting groove 6, and the cleaning plate 12 to scrape off the plastic attached to the inner wall of the feed pipe 2. The chamfer 17 on the side of the cleaning plate 12 can facilitate the discharge of plastic through the chamfer 17 and prevent plastic from accumulating on the surface of the cleaning plate 12.

[0028] Example 3: Figure 4 and Figure 5 As shown, a support rod 10 is provided to facilitate cleaning of the cleaning plate 12. One end of the support rod 10 is fixedly connected to the inner ring surface of the first bearing 9. A chamfer 17 is provided on the inner side of the cleaning plate 12, and a positioning groove 18 is provided on the outer side of the cleaning plate 12. A shielding plate 19 is provided on the surface of the cleaning plate 12, which covers the side of the lifting groove 6. A vertical plate 20 is provided on the surface of the lifting plate 8. A through hole is provided on the side of the vertical plate 20, and a fixing rod 21 is inserted into the through hole. A limiting spring 22 is sleeved on the surface of the fixing rod 21. One end of the limiting spring 22 is fixedly connected to the surface of the fixing rod 21, and the other end of the limiting spring 22 is fixedly connected to the side of the vertical plate 20. One end of the fixing rod 21 is inserted into the positioning groove 18.

[0029] More specifically, when the cleaning plate 12 moves upward, the fixing rod 21 can be pulled to disengage from the positioning groove 18, thereby allowing the cleaning plate 12 to rotate in conjunction with the first bearing 9, which facilitates cleaning of the cleaning plate 12. The cover plate 19 can be used to prevent plastic from entering the lifting groove 6 during material feeding.
