Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1-4As shown, one embodiment of this utility model provides an injection molding device for producing notebook keyboard accessories, including an electric push rod 1, a fixed frame 2, an upper mold base 3, a limiting column 4, a lower mold base 5, a control valve 6, a cooling ring 7, a conveying pipe 8, and a feeding pipe 9. The limiting column 4 is fixedly connected to the bottom of the four corners of the fixed frame 2. The electric push rod 1 is symmetrically fixedly installed on the fixed frame 2. The upper mold base 3 is slidably disposed below the fixed frame 2 through the limiting column 4, and the driving end of the electric push rod 1 is fixedly connected to the upper end of the upper mold base 3. The lower mold base 5 is fixedly connected to the bottom end of the limiting column 4, and the lower mold base 5 is located directly below the upper mold base 3. The feeding pipe 9 is fixedly connected to the middle of the bottom end of the lower mold base 5.

[0018] The bottom end of the feed pipe 9 is fixedly connected to a first connecting flange 10, and the bottom end of the feed pipe 9 is fixedly connected to a screening and filtering body 11 through the first connecting flange 10.

[0019] The screening and filtering body 11 includes a second connecting flange 12, a filter cylinder 13, a third connecting flange 14, fixing bolts 16, a screening and filtering disc 17, and screening and filtering holes 18. The second connecting flange 12 and the third connecting flange 14 are respectively fixedly connected to both ends of the filter cylinder 13. The screening and filtering disc 17 is fixedly installed inside the filter cylinder 13 on the side near the second connecting flange 12 by fixing bolts 16. The screening and filtering holes 18 are evenly opened on the screening and filtering disc 17. During the extrusion and conveying process, the screening and filtering disc 17 fixedly installed inside the filter cylinder 13 can intercept, filter, and store large particles in the material inside the filter cylinder 13.

[0020] The second connecting flange 12 is fixedly connected to the first connecting flange 10 by bolts, which facilitates fixing and disassembly.

[0021] Pressure sensors 15 are fixedly installed on both sides of the filter cartridge 13 to detect pressure changes and help determine the presence of large particles inside the filter cartridge 13.

[0022] Working Principle: During the injection molding process, the filter cylinder 13 is connected to the external feeding equipment via the third connecting flange 14. This allows the injection molding material to be conveyed to the lower mold base 5 through the filter cylinder 13 and the feed pipe 9. During the extrusion and conveying process, the screening filter disc 17 fixed inside the filter cylinder 13 intercepts and filters large particles in the material, storing them inside the filter cylinder 13. This ensures that the material extruded from inside the filter cylinder 13 to the feed pipe 9 is free of large particles, resulting in high-quality injection-molded products. However, if a large number of large particles are stored inside the filter cylinder 13, the flow rate inside the filter cylinder 13 deteriorates. In this case, the pressure sensors 15 installed on both sides of the filter cylinder 13 will detect the large extrusion pressure inside the filter cylinder 13, thus detecting and removing these particles. The detection information is transmitted to the display terminal, allowing the testing personnel to promptly clean the large particles intercepted and stored inside the filter cylinder 13. The screening filter plate 17 can be easily removed and replaced from inside the filter cylinder 13. The interception and filtration level inside the filter cylinder 13 can be adjusted and controlled according to the needs of use. During injection molding, two conveying pipes 8 set on the cooling ring 7 are connected to the external conveying hose. One conveying pipe 8 delivers very low-temperature coolant to the inside of the cooling ring 7, so that the product inside can be quickly cooled and molded when the upper mold base 3 and the lower mold base 5 are closed for injection molding, which improves the efficiency of production preparation. When the temperature of the liquid inside the cooling ring 7 rises, it is discharged by another control valve 6, thereby ensuring that the cooling ring 7 can continuously and stably dissipate heat, so that the injection-molded finished product can be quickly cooled and molded.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
