[0025] 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.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] A high-breathability automotive interior polyurethane composite leather molding mold includes a housing 1. A bracket 2 is fixedly connected to the rear side of the top of the housing 1, and a hydraulic cylinder 3 is fixedly connected to the top of the bracket 2. A heating component 4 is fixedly connected to the top of the housing 1, and a connecting component 5 is fixedly connected to the side of the heating component 4 opposite to the hydraulic cylinder 3. The connecting component 5 includes a fixing plate 501, a T-shaped block 502 is fixedly connected to the top of the fixing plate 501, and a positioning rod 503 is fixedly connected to the right side inside the T-shaped block 502. T-shaped moving blocks 504 are slidably connected to both sides of the surface of the positioning rod 503, and a slot block 505 is fixedly connected to the right side of the T-shaped moving block 504 extending to the right side of the T-shaped block 502. A return spring 506 is sleeved on the surface of the positioning rod 503, and the two ends of the return spring 506 are fixedly connected to the two T-shaped moving blocks 504. A mold body 6 is slidably connected to the surface of the two T-shaped blocks 502, and the two mold bodies 6 fit together.

[0028] In this embodiment: by moving the slot block 505, the T-shaped moving block 504 is driven to move smoothly under the restriction of the positioning rod 503 and the return spring 506 is released, releasing the locking effect of the connecting component 5. This allows the mold body 6 to move smoothly under the restriction of the T-shaped block 502 to complete the initial positioning. At the same time, under the action of the return spring 506, the T-shaped moving block 504 and the slot block 505 can be driven to return smoothly to their original positions, so that the T-shaped buckle block 11 can be inserted into the slot block 505 to complete the engagement. This allows for quick replacement of the mold body 6 to adapt to the processing of polyurethane composite leather for automotive interiors of different specifications, and also forms a double fixing structure. The structure prevents displacement and falling, ensuring the quality of composite leather molding and improving the ease of use of the connecting component 5. Then, under the action of the infusion pump 402, the heat-conducting liquid in the storage tank 401 flows into the U-shaped storage block 405 through the infusion pipe 404, forming a heating area around the bottom mold and completing the heating of the mold body 6. At the same time, the heat-conducting liquid can flow back into the storage tank 401 through the return pipe 406, realizing the recycling of the heat-conducting liquid. Together with the electric heating block 403, the heat-conducting liquid is heated to form a circulating heating system, ensuring the quality of composite leather molding and improving the practicality of the device.

[0029] Specifically, such as Figure 4As shown, the heating assembly 4 includes a liquid storage tank 401. An infusion pump 402 is fixedly connected to the bottom right side of the liquid storage tank 401, and an electric heating block 403 is fixedly connected inside the liquid storage tank 401. An infusion tube 404 is fixedly connected to the side of the infusion pump 402 away from the liquid storage tank 401. A U-shaped liquid storage block 405 is fixedly connected to the other end of the infusion tube 404, and a bottom fixing plate 501 is located inside the U-shaped liquid storage block 405. A return pipe 406 is fixedly connected to the left side of the U-shaped liquid storage block 405, and the other end of the return pipe 406 is fixedly connected to the liquid storage tank 401.

[0030] Specifically, such as Figure 2 , Figure 4 As shown, a battery pack 7 is fixedly connected to the rear side of the liquid storage tank 401, and the battery pack 7 is electrically connected to the electric heating block 403.

[0031] Specifically, such as Figure 4 As shown, an observation glass 8 is embedded inside the front side of the liquid storage tank 401, and an inlet valve 9 is fixedly connected to the top of the liquid storage tank 401.

[0032] In this embodiment: by observing the cooperation between the glass 8 and the liquid inlet valve 9, the condition of the heat-conducting liquid in the storage tank 401 can be observed in real time, and the liquid inlet valve 9 can be used to replace it to ensure the performance of the heat-conducting liquid. At the same time, the battery pack 7 can stably supply power to the electric heating block 403 to complete the heating of the heat-conducting liquid, providing support for the heating of the mold body 6 and improving the convenience of using the heating component 4.

[0033] Specifically, such as Figure 3 As shown, both mold bodies 6 have T-slots 10 on opposite sides for use with T-blocks 502, and the surface of the T-blocks 502 contacts the inner wall of the T-slots 10. T-blocks 11 are fixedly connected to the front and rear sides of the right side of the mold body 6, and the slot blocks 505 are slidably connected to the surface of the T-blocks 11.

[0034] Specifically, such as Figure 5 As shown, each of the two slot blocks 505 has a positioning groove 12 on its opposite side for use with the T-shaped buckle block 11, and the surface of the T-shaped buckle block 11 is in contact with the inner wall of the positioning groove 12.

[0035] In this embodiment: the T-shaped block 502 and the T-slot 10 cooperate to form a snap-fit ​​structure, realizing the initial positioning of the mold body 6 and the connecting component 5, so that the mold body 6 can be quickly installed in the designated position. At the same time, with the help of the return spring 506, the slot block 505 can be driven to return smoothly, so that the T-shaped snap-fit ​​block 11 is embedded in the positioning groove 12 to complete the snap-fit. The two cooperate to quickly replace the mold body 6 to adapt to the processing of different specifications of automotive interior polyurethane composite leather, and also form a double fixing structure to prevent the phenomenon of displacement and falling off, ensuring the quality of composite leather molding and improving the ease of use of the connecting component 5.

[0036] Specifically, such as Figure 1 , Figure 2 As shown, a movable door 13 is movably connected to the front side of the chassis 1, and a control console 14 is fixedly connected to the front side of the movable door 13. The control console 14 is electrically connected to the hydraulic cylinder 3 and the heating component 4.

[0037] Specifically, such as Figure 1 , Figure 2 As shown, slide rods 15 are movably connected to the four corners of the top of the bracket 2, and the bottom of the slide rods 15 extends into the interior of the bracket 2 and is fixedly connected to the top connecting component 5. A fixed circular plate 16 is fixedly connected to the top of the slide rods 15, and a buffer spring 17 is sleeved on the surface of the slide rods 15. The two ends of the buffer spring 17 are fixedly connected to the fixed circular plate 16 and the bracket 2, respectively.

[0038] In this embodiment: Through the function of the control console 14, the operating parameters of the hydraulic cylinder 3 and the heating component 4 can be set according to the actual situation to realize the automated operation of the device. It can not only uniformly heat the mold body 6 to ensure the quality of composite leather molding, but also drive the hydraulic cylinder 3 to drive the top connecting component 5 to move smoothly under the restriction of the slide rod 15, ensuring the accurate mold closing of the mold body 6 and reducing the scrapping of composite leather caused by mold closing deviation. At the same time, the buffer spring 17 can buffer the impact force during mold closing, reduce damage to the mold body 6 and the device, extend the service life of the device, and improve the practicality of the device.

[0039] Working Principle: When processing automotive interior trim, the slot block 505 is first manually moved, causing the T-shaped moving block 504 to move smoothly under the constraint of the positioning rod 503 and compress the return spring 506, releasing the locking effect of the connecting component 5. This allows the mold body 6 to move smoothly under the constraint of the T-shaped block 502 to complete the initial positioning. After the mold body 6 is fixed, the rebound force of the return spring 506 causes the T-shaped moving block 504 and the slot block 505 to return smoothly to their original positions, allowing the T-shaped buckle block 11 to accurately embed into the positioning groove 12 of the slot block 505 to complete the engagement. This allows for quick replacement of the mold body 6, adapting to the processing of different specifications of automotive interior polyurethane composite leather, and also forms a double fixing structure to prevent displacement and falling, ensuring the quality of the composite leather molding. During the processing stage, the operator can set the parameters via the control panel 14. The operating parameters of the hydraulic cylinder 3 and the heating component 4 are set as follows: the infusion pump 402 is started, driving the heat-conducting liquid in the storage tank 401 to be transported to the U-shaped storage block 405 through the infusion pipe 404, forming a heating area around the bottom mold, achieving uniform heating of the mold body 6. At the same time, the heat-conducting liquid in the U-shaped storage block 405 is returned to the storage tank 401 through the return pipe 406, and the electric heating block 403 continuously heats the circulating liquid, building a stable circulating heating system to ensure uniform and stable mold temperature. Then, the hydraulic cylinder 3 is started to drive the top connecting component 5 to move smoothly under the restriction of the slide bar 15, ensuring the accurate closing of the two mold bodies 6 and reducing scrap caused by mold closing deviation. At the same time, the buffer spring 17 can buffer the impact force during mold closing, reducing damage to the mold body 6 and the device, and extending the service life of the device.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
