[0002] Currently, rear door trim panel molds with heat dissipation functions are specifically designed for manufacturing interior trim panels for automobiles or other equipment. Combining traditional decorative functions with heat dissipation design, they effectively manage and disperse heat. By incorporating ventilation holes, heat sinks, or thermally conductive materials into the structure, these molds optimize heat exchange, improve the heat dissipation efficiency of electronic devices, extend their service life, and enhance safety and comfort. They are commonly used in automobiles, home appliances, and other electronic devices requiring heat dissipation. Through the selection of high thermal conductivity materials and sophisticated mold design, both the aesthetics and strength of the trim panel are ensured, while thermal management requirements are met.

[0003] However, existing rear door trim panel molds with heat dissipation functions have the following drawbacks: for example, in the prior art, the heat dissipation structure of the rear door trim panel mold is usually directly fixed inside the mold and cannot be disassembled, resulting in the inability to clean and replace it after long-term use. Summary of the Invention

[0004] The purpose of this application is to solve the problem that the internal heat dissipation structure of the mold cannot be disassembled for cleaning and replacement.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a rear door decorative panel mold with heat dissipation function, including a support platform, a lower mold fixedly connected to the upper surface of the support platform, a heat dissipation groove opened inside the lower mold, a heat dissipation frame slidably connected inside the heat dissipation groove, two heat dissipation frames are provided, the two heat dissipation frames are respectively set at both ends inside the heat dissipation groove, a fan is fixedly connected inside the heat dissipation frame, a heat dissipation fin is slidably connected inside the heat dissipation frame, a sliding shaft is slidably connected inside the heat dissipation fin, the sliding shaft is set on the upper and lower sides inside the heat dissipation fin, the sliding shaft is slidably connected inside the heat dissipation frame, threaded grooves are provided at both ends of the outer wall of the sliding shaft, and nuts are threadedly connected to the outer wall of the sliding shaft.

[0006] As a preferred embodiment, the heat dissipation frame is slidably connected to a first locking block, which is slidably connected to the interior of the lower mold. The outer wall of the first locking block is provided with a first spring, one end of which is fixedly connected to the interior of the first locking block, and the other end of which is fixedly connected to the interior of the heat dissipation frame. The heat dissipation frame is slidably connected to a second locking block, which is slidably connected to the interior of the lower mold. The outer wall of the second locking block is provided with a second spring, one end of which is fixedly connected to the interior of the second locking block, and the other end of which is fixedly connected to the interior of the heat dissipation frame.

During the sliding process, the first and second locking blocks compress the first and second springs respectively. Then place the two heat sink frames inside the lower mold and release the first and second locking blocks. The elasticity of the first and second springs drives the first and second locking blocks to automatically reset and lock into the lower mold for fixation. The combination of the fan and the heat sink cools the interior of the lower mold, so that the heat sink structure can be easily disassembled and assembled.

[0013] (2) By connecting the input end of cooling pump one and the output end of cooling pump two inside the cooling tank, cooling pump one draws out the coolant and then delivers it into the interior of the cooling pipe through the liquid delivery pipe. Then, cooling pump two is started to draw out the coolant inside the cooling pipe through the liquid extraction pipe, so that the coolant circulates inside the cooling pipe and cools down the lower mold and the upper mold.

[0026] like Figure 1-7 The rear door decorative panel mold with heat dissipation function shown includes a support platform 1. A lower mold 2 is fixedly connected to the upper surface of the support platform 1. A heat dissipation groove 4 is opened inside the lower mold 2. Cold air flows inside the heat dissipation groove 4 to dissipate heat from the interior of the lower mold 2. A heat dissipation frame 3 is slidably connected inside the heat dissipation groove 4. Two heat dissipation frames 3 are provided, and the two heat dissipation frames 3 are respectively set at both ends inside the heat dissipation groove 4. A fan 5 is fixedly connected inside the heat dissipation frame 3. A heat dissipation fin 6 is slidably connected inside the heat dissipation frame 3. A sliding shaft 7 is slidably connected inside the heat dissipation fin 6 on the upper and lower sides inside the heat dissipation fin 6. The sliding shaft 7 is slidably connected inside the heat dissipation frame 3. Threaded grooves are provided at both ends of the outer wall of the sliding shaft 7. Nuts 8 are threadedly connected to the outer wall of the sliding shaft 7. The two sliding shafts 7 and multiple nuts 8 are combined to form a heat dissipation frame 3. To facilitate the assembly and disassembly of the heat sink 6, a locking block 9 is slidably connected inside the heat sink frame 3. The locking block 9 is slidably connected inside the lower mold 2. A spring 10 is provided on the outer wall of the locking block 9. One end of the spring 10 is fixedly connected inside the locking block 9, and the other end of the spring 10 is fixedly connected inside the heat sink frame 3. A locking block 2 11 is slidably connected inside the heat sink frame 3. The locking block 2 11 is slidably connected inside the lower mold 2. A spring 2 12 is provided on the outer wall of the locking block 2 11. One end of the spring 2 12 is fixedly connected inside the locking block 2 11, and the other end of the spring 2 12 is fixedly connected inside the heat sink frame 3. Through the elastic action of the spring 1 10 and the spring 2 12, the locking blocks 1 9 and 2 11 can be automatically reset and locked inside the lower mold 2 for fixation, thus facilitating the assembly and disassembly of the heat sink frame 3.

[0027] A cooling pump 13 is fixedly connected to the upper surface of the support platform 1. A liquid delivery pipe 14 is fixedly connected to the output end of the cooling pump 13. A cooling pipe 15 is fixedly connected to the outer wall of the liquid delivery pipe 14. The cooling pipe 15 is fixedly connected to the inside of the lower mold 2. The input end of the cooling pump 13 is connected to the cooling box. A cooling pump 26 is fixedly connected to the upper surface of the support platform 1. A liquid extraction pipe 17 is fixedly connected to the input end of the cooling pump 26. The liquid extraction pipe 17 is fixedly connected to the inside of the cooling pipe 15. The output end of the cooling pump 26 is connected to the cooling box. The combined use of the cooling pump 13 and the cooling pump 26 allows the coolant to circulate inside the cooling pipe 15, thereby cooling the lower mold 2 and the upper mold 21.

[0028] The lower mold 2 has a lower mold groove 18 inside and a positioning hole 19 inside. A positioning shaft 20 is slidably connected inside the positioning hole 19. The combination of the positioning hole 19 and the positioning shaft 20 facilitates the positioning and fitting of the lower mold 2 and the upper mold 21. The upper mold 21 is fixedly connected to the upper end of the positioning shaft 20. The upper mold 21 has an upper mold groove 22 inside and is slidably connected to the outer wall of the cooling pipe 15. An injection tube 23 is fixedly connected inside the upper mold 21. A decorative panel body 24 is slidably connected inside the lower mold groove 18 and is slidably connected inside the upper mold groove 22. The raw material is injected through the injection tube 23, and the decorative panel body 24 is formed by combining the lower mold groove 18 inside the lower mold 2 and the upper mold groove 22 inside the upper mold 21.

[0029] Working principle: In use, the upper mold 21 is fixedly connected to the stamping machine, and the injection tube 23 is connected to the raw material conveying pipe. The stamping machine drives the upper mold 21 to slide down. The upper mold 21 slides down and drives the positioning shaft 20 to slide into the positioning hole 19. At the same time, the upper mold 21 is locked on the outer wall of the cooling pipe 15. The raw material is injected into the upper mold groove 22 and the lower mold groove 18 through the raw material conveying pipe and the injection tube 23 to start making the decorative panel body 24. The fans 5 inside the two sets of heat dissipation frames 3 are started. One fan 5 rotates clockwise and the other fan 5 rotates counterclockwise. The clockwise rotating fan 5 blows the outside air. Air enters the heat dissipation frame 3, is cooled by the heat sink 6, and then enters the heat dissipation tank 4. Another counterclockwise rotating fan 5 draws air out of the heat dissipation tank 4 and discharges it to the outside of the lower mold 2, achieving air circulation and thus cooling the interior of the lower mold 2. Cooling pump 13 is started to draw out coolant and deliver it to the interior of cooling pipe 15 through the delivery pipe 14. Then, cooling pump 2 16 is started in conjunction with the extraction pipe 17 to draw out the coolant from the interior of cooling pipe 15 and deliver it back to the cooling tank, so that the coolant circulates inside the cooling pipe 15. The coolant then cools the lower mold 2 and the upper mold 2 through the cooling pipe 15. 1. It serves to cool and reduce temperature, quickly cooling the decorative panel body 24 to form a mold. For long-term use, the fan 5 needs cleaning, and the heat sink 6 needs replacement. Simultaneously, press the first locking block 9 and the second locking block 11, causing them to slide towards the center of the heat sink frame 3 and compress the first spring 10 and the second spring 12, allowing them to slide out of the lower mold 2. At this point, pulling the heat sink frame 3 outwards will disassemble it from the lower mold 2. Then, rotating the nut 8 to pull out the sliding shaft 7 allows for the removal and replacement of the heat sink 6. Simultaneously, the fan 5 can be cleaned. During installation, place the new heat sink 6 inside the heat dissipation frame 3, insert two sliding shafts 7 through the heat dissipation frame 3 and the heat sink 6, and thread the nuts 8 to both ends of the sliding shafts 7 for fixation. At the same time, press the first locking block 9 and the second locking block 11 to slide the first locking block 9 and the second locking block 11 towards the middle and compress the first spring 10 and the second spring 12. Place the heat dissipation frame 3 inside the heat dissipation slot 4 at both ends, release the first locking block 9 and the second locking block 11, and use the elasticity of the first spring 10 and the second spring 12 to drive the first locking block 9 and the second locking block 11 to automatically reset and lock into the lower mold 2, so as to achieve quick disassembly and assembly and facilitate the cleaning and replacement of the heat dissipation structure.
