[0002] Injection molding is a process used to manufacture injection molded parts during the processing of air conditioners. Injection molding is a process in which plastic raw materials are melted at high temperature and injected into a mold, and then cooled to obtain plastic products of the desired shape and size. Air conditioner injection molded parts mainly include fan blades, filters, housings, drain pipes, etc.

[0003] Injection molding machines are mainly used for processing during the injection molding process. Injection molding machines are the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting materials. Injection molding machines consist of two basic components: an injection device and a mold clamping device for hot melting and feeding plastic into the mold.

[0031] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In this application, the directions or positional relationships indicated by the terms "upper", "inner", "outer", "middle", etc. are based on the directions or positional relationships shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0033] like Figure 1 and Figure 2 As shown, a feeding mechanism of an air-conditioning plastic parts injection molding machine includes a feed box 1, and a visual window 2 is provided on the side wall of the feed box 1; the material condition in the feed box 1 can be observed through the visual window 2, and abnormal conditions can be discovered and handled in time, thereby ensuring the smoothness of the feeding process and improving production efficiency. The lower end of the feed box 1 is set in a conical shape; thereby improving the feeding efficiency, allowing the material to flow more smoothly in the feed box 1, and avoiding material retention and blockage. The lower end of the feed box 1 is rotatably connected to a stirring roller 3, and a driving motor 4 drives the stirring roller 3 to rotate, and the driving motor 4 is connected to the side wall of the feed box 1. When the material is retained and blocked, the driving motor 4 drives the stirring roller 3 to rotate, and then the stirring roller 3 stirs the material, driving the material to flow, thereby ensuring the smoothness of the feeding process.

[0034] A feeding pipe 5 is installed at the lower end of the feed box 1, and the feed box 1 is connected to the feeding pipe 5. A feeding frame 6 is slidably connected in the feeding pipe 5, and the feeding frame 6 is pushed by the first cylinder 7; one end of the feeding pipe 5 is connected to a track 13, and the track 13 is connected to the feeding frame 6. The stability of the sliding of the feeding frame 6 is guaranteed. The lower end of the end of the feeding pipe 5 is connected to the feeding pipe 8. Then, when the material is transported, the first cylinder 7 pushes the feeding frame 6 to slide in the feeding pipe 5, and then the upper end of the feeding frame 6 corresponds to the feed box 1, and then the material in the feed box 1 falls into the feeding frame 6, and then the first cylinder 7 continues to push the feeding frame 6 to slide in the feeding pipe 5, and then the lower end of the feeding frame 6 corresponds to the feeding pipe 8, and then the material slides through the feeding pipe 8, and the feeding is completed. Furthermore, during the feeding process, the amount of feed can be controlled by the feed frame 6, thereby ensuring the uniformity of the feed amount, avoiding the waste of raw materials, and ensuring the stability of product quality and performance.

[0035] like Figure 3As shown, a heating wire 9 is provided inside the feed pipe 5, so that the material can be heated and dried again, and the moisture in the material transportation process can be removed, thereby improving the performance and service life of the injection molded parts. The upper end of the end of the feed pipe 5 is connected to a blower 10, and the lower end of the feed pipe 5 corresponding to the blower 10 is connected to a filter 11. The filter 11 is snapped into the material receiving box 12, and the material receiving box 12 is slidably connected in the feed pipe 5. In this way, impurities in the material can be removed, and the appearance and performance quality of the injection molded parts are improved. The removed impurities fall into the material receiving box 12 through the filter 11, avoiding pollution to the working environment and reducing the workload. The material receiving box 12 is slidably connected in the feed pipe 5, thereby facilitating the cleaning and replacement of the filter 11.

[0036] like Figure 4 As shown, the other end of the feeding pipe 5 is rotatably connected with a baffle 14, and a torsion spring 15 is connected between the baffle 14 and the feeding pipe 5. When the first cylinder 7 continues to push the feeding frame 6 to slide in the feeding pipe 5, the baffle 14 closes the feeding pipe 5. When the feeding frame 6 pushes out of the feeding pipe 5, the feeding frame 6 drives the baffle 14 to rotate, and then the baffle 14 is reset by the torsion spring 15 when rotating in the reverse direction, thereby ensuring the closed nature of the working environment.

[0037] The working process of the utility model is:

[0038] The material is stored in the feed box 1, and the first cylinder 7 pushes the feed frame 6 to slide in the feed pipe 5, so that the upper end of the feed frame 6 corresponds to the feed box 1, and the material in the feed box 1 falls into the feed frame 6, and the first cylinder 7 continues to push the feed frame 6 to slide in the feed pipe 5, the heating wire 9 can heat and dry the material again, the blower 10 removes impurities in the material, and then the lower end of the feed frame 6 corresponds to the feed pipe 8, and then the material slides through the feed pipe 8, and the feeding is completed.
