Description

Technical Field

[0001] This utility model relates to the field of remote control shell injection molding technology, specifically to an integrated injection mold for remote control shells. Background Technology

[0002] The remote control casing refers to the external structure used to protect and enclose the internal electronic components of the remote control. It not only has a protective function, but also serves to enhance aesthetics, provide a comfortable feel, and prevent slippage. Injection molding, as an efficient production process, is widely used in the manufacture of plastic products. Remote control casings are usually made of engineering plastics because they have good strength, heat resistance, and chemical resistance, which can meet the usage requirements of electronic products.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1-5 As shown, in this embodiment, a one-piece injection mold for a remote control housing includes a mold body 1. An upper module 8 is slidably connected between the inner walls of the mold body 1. A lifting assembly is provided inside the mold body 1 to move the upper module 8. A model 22 is fixedly connected to the bottom of the upper module 8. A lower module 15 is fixedly connected to the bottom of the inner side of the mold body 1. An injection groove 16 is opened on the top of the lower module 15. The inner side of the injection groove 16 contacts the model 22. A circulating water pipe 20 is fixedly connected inside the lower module 15. Both ends of the circulating water pipe 20 extend to one side of the mold body 1. A [missing information - likely a design element] is opened on one side of the mold body 1. There is a water inlet 18 and a water outlet 19, which are connected to both ends of the circulating water pipe 20. A cooling component is provided on one side of the mold body 1 for heat dissipation inside the mold body 1. A guide groove 21 is provided inside the upper module 8, which passes through the mold 22. A feed inlet 14 is provided on one side of the upper module 8, which is connected to the inside of the guide groove 21. Two fitting grooves 24 are provided at the bottom of the inner side of the injection tank 16. A top block 17 is slidably connected between the inner walls of the two fitting grooves 24. A return spring 25 is fixedly connected between the two top blocks 17 and the inner sides of the two fitting grooves 24.

[0024] When injection molding a remote control shell using an integrated injection mold, the lifting assembly first moves the upper module 8 downward between the inner walls of the mold body 1, allowing the mold 22 to enter the injection groove 16. This presses down the two top blocks 17 into the two fitting grooves 24, simultaneously compressing the two return springs 25 made of high-carbon steel. Then, the feed inlet 14 and guide channel 21 inject the remote control shell molding material into the injection groove 16. Cooling water is then injected into the circulating water pipe 20 inside the lower module 15 through the water inlet 18, and then discharged through the outlet 19, thus circulating water cooling the remote control shell. Simultaneously, the air-cooling assembly further cools the interior of the mold body 1, allowing the remote control shell to cool and solidify quickly. Next, the lifting assembly moves the upper module 8 upward again, and the spring force of the two return springs 25, made of high-carbon steel, lifts the top blocks 17, thus lifting the fully cooled and solidified remote control shell for easy collection. This improves the injection efficiency and quality of the integrated injection mold.

[0025] like Figures 1-5As shown, the lifting assembly includes a threaded rod 12 and a guide rod 13. The threaded rod 12 is rotatably connected between the inner walls of the mold body 1, and the top end of the threaded rod 12 extends to the top of the mold body 1. A lifting plate 9 is threadedly connected to the outer side of the threaded rod 12. The guide rod 13 is fixedly connected between the inner walls of the mold body 1, and a guide plate 10 is slidably connected to the outer side of the guide rod 13. The lifting plate 9 and the guide plate 10 are respectively fixedly connected to both sides of the upper module 8. A mounting plate 2 is fixedly connected to the top of the mold body 1. A worm gear 4 is rotatably connected to one side of the mounting plate 2. A worm wheel 3 is fixedly connected to the extended end of the threaded rod 12. The worm wheel 3 meshes with the worm gear 4. A lifting motor 5 is fixedly installed on one side of the mounting plate 2. The output end of the lifting motor 5 passes through the mounting plate 2 and is fixedly connected to the worm gear 4.

[0026] The lifting motor 5 drives the worm gear 4 to rotate on one side of the mounting plate 2, which causes the worm wheel 3 to drive the threaded rod 12 to rotate between the inner walls of the mold body 1. Then, the lifting plate 9 and the guide plate 10 on the outside of the guide rod 13 drive the upper module 8 to move between the inner walls of the mold body 1, which further improves the injection efficiency of the one-piece injection mold.

[0027] like Figures 1-5 As shown, the air-cooled assembly includes a heat dissipation frame 6, the interior of which is connected to the mold body 1. A heat dissipation fan blade 23 is rotatably connected between the inner walls of the heat dissipation frame 6. A heat dissipation groove 11 is provided on one side of the mold body 1. A heat dissipation motor 7 is fixedly installed on one side of the heat dissipation frame 6. The output end of the heat dissipation motor 7 extends into the interior of the heat dissipation frame 6 and is fixedly connected to the heat dissipation fan blade 23.

[0028] The cooling motor 7 drives the cooling fan blades 23 to rotate between the inner walls of the cooling frame 6, and the heat is discharged through the cooling groove 11, thereby improving the efficiency and quality of the remote control shell cooling and molding.

[0029] This utility model provides an integrated injection mold for a remote control shell. The specific working principle is as follows: When injection molding the remote control shell using the integrated injection mold, firstly, the external controller is connected to an external power supply. Then, the external controller starts the lifting motor 5. The lifting motor 5 drives the worm gear 4 to rotate on one side of the mounting plate 2, causing the worm wheel 3 to drive the threaded rod 12 to rotate between the inner walls of the mold body 1. Next, the upper module 8 moves downward between the inner walls of the mold body 1 through the lifting plate 9 and the guide plate 10 on the outside of the guide rod 13, causing the model 22 to enter the injection groove 16. This presses down the two top blocks 17 into the two fitting grooves 24, simultaneously pressing down the two return springs 25 made of high-carbon steel. Then, the feed port 14 and the guide groove 21 inject the remote control shell injection material into the injection groove 16. Finally, cooling water is injected into the lower mold through the water inlet 18. The water flows through the circulating water pipe 20 inside block 15 and then out through the outlet 19, thus circulating water cooling the remote control shell. At the same time, the cooling motor 7 drives the cooling fan blades 23 to rotate between the inner walls of the cooling frame 6 and exhausts the heat through the cooling groove 11, further cooling the interior of the mold body 1, so that the remote control shell can be quickly and fully cooled and formed. Then, the lifting motor 5 drives the worm gear 4 to rotate on one side of the mounting plate 2, so that the worm wheel 3 drives the threaded rod 12 to rotate between the inner walls of the mold body 1. Then, the lifting plate 9 and the guide plate 10 on the outside of the guide rod 13 drive the upper module 8 to move upward between the inner walls of the mold body 1. Then, the elastic force of the two return springs 25 made of high carbon steel pushes up the top block 17 and lifts up the fully cooled and formed remote control shell for easy collection, thus completing the integrated injection molding of the remote control shell.
