Description

Technical Field

[0001] This utility model relates to the technical field of pre-compression devices, specifically a pre-compression device for automotive interior processing. Background Technology

[0002] The pre-compression device for automotive interior processing is a special equipment used for the preliminary shaping of automotive interior materials before molding. Its core function is to apply controllable pressure to form a preliminary outline and fix the basic shape of soft or semi-finished interior materials (such as leather, fabric, foam board, etc.), thereby eliminating material wrinkles, evenly distributing internal stress, and providing a stable basic shape guarantee for subsequent hot pressing or precision processing, ensuring that the final product has accurate dimensions, a flat surface and a stable structure.

[0003] According to a relevant patent (patent number: 202321381587.6), a pre-pressing device for processing injection-molded automotive interior parts includes a housing. Pressure plates are slidably connected to the upper and lower parts of the inner side of the housing, and side plates are fixedly connected to the upper and lower parts of one side of the outer wall of the housing. A drive motor is bolted to the top of one of the side plates, and a bidirectional screw is rotatably connected between the two side plates. The proposed method, using two nut seats to drive two pressure plates to pre-press the material from both above and below, not only improves pre-pressing efficiency but also makes the pre-pressing effect more thorough, making it highly practical. However, it lacks a cooling function after pre-pressing. The pre-pressed material cannot cool down quickly and requires a long period of natural cooling before entering the next process, passively extending the single production cycle, significantly reducing equipment utilization, and forcing the production line to configure additional cooling stations or extend waiting times. This disrupts the connection rhythm between pre-pressing and subsequent processes, restricting the overall production pace. Utility Model Content

[0004] The purpose of this utility model is to provide a pre-compression device for automotive interior processing, in order to solve the problem mentioned in the background art that the pre-compression process lacks a cooling function. The pre-compressed material cannot be cooled down quickly and needs to be naturally cooled for a long time before it can enter the next process, which leads to a passive extension of the single production cycle, a significant reduction in equipment utilization, and forces the production line to be equipped with additional cooling stations or extend the waiting time, which disrupts the connection rhythm between pre-compression and subsequent processes and restricts the overall production rhythm.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-pressing device for automotive interior processing, comprising a bracket, a base fixedly connected to the center of the top of the bracket, a cooling groove formed at the center of the top of the base, a lower pressing mold arranged inside the cooling groove, a support block fixedly connected to the bottom of the cooling groove, a second connecting plate fixedly connected to the top of the surface of the lower pressing mold, a first connecting plate fixedly connected to the top of the surface of the base, a slot formed at the upper end of the base, an insert plate fixedly connected to the lower end of the second connecting plate, a sealing gasket fixedly connected to the bottom of the insert plate, a liquid pump fixedly installed on one side of the top of the bracket, an inlet pipe and a serpentine pipe fixedly connected to the top positions of both sides of the cooling groove, a liquid storage tank fixedly connected to one side of the lower end of the bracket, a liquid extraction pipe fixedly connected to one side of the top of the liquid storage tank, a horizontal plate fixedly connected to the bottom position of the inner wall of the bracket, two fans fixedly installed at the center and one side positions of the bottom of the horizontal plate, the tops of the four fans extending to the outside of the horizontal plate, and an upper pressing mold provided at the upper end of the lower pressing mold.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This pre-compression device for automotive interior processing utilizes a design incorporating a base, slot, insert plate, sealing gasket, support block, liquid pump, reservoir, inlet pipe, extraction pipe, serpentine pipe, and fan. The base serves as the core support structure, with a cooling groove at its top providing a stable installation space for the lower compression mold. Combined with multiple internal support blocks, it effectively disperses the pressure generated during pre-compression, ensuring the stability of the lower compression mold. The slot and insert plate, along with the sealing gasket at the bottom of the insert plate, seal the cooling groove, preventing coolant leakage and ensuring smooth cooling. The liquid pump draws coolant from the reservoir through the extraction pipe, injects it into the cooling groove through the inlet pipe, and then through the serpentine pipe... The coolant flows back to the storage tank, forming a circulating cooling system that quickly removes the heat generated during the pre-compression process, shortens the cooling time, and reduces the risk of material deformation due to prolonged high temperatures. Simultaneously, uniform cooling avoids localized thermal stress concentration, improving the dimensional accuracy and surface smoothness of the product. Furthermore, the directional airflow generated by the fan directly blows across the walls of the serpentine tube, significantly enhancing the heat exchange efficiency between the coolant inside the tube and the external environment by accelerating the airflow outside the tube. This gas-liquid synergistic cooling design improves the heat dissipation capacity of the serpentine tube, thereby shortening the mold cooling cycle and avoiding the localized temperature stagnation problems that may occur with simple liquid cooling, ensuring uniform cooling.

[0015] 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.

[0016] Please see Figure 1-6 This utility model provides a technical solution: a pre-pressing device for automotive interior processing, including a bracket 1, a base 2 fixedly connected to the center of the top of the bracket 1, a cooling groove 23 formed at the center of the top of the base 2, a lower pressing mold 3 disposed inside the cooling groove 23, a support block 9 fixedly connected to the bottom of the cooling groove 23, a second connecting plate 5 fixedly connected to the top of the surface of the lower pressing mold 3, a first connecting plate 4 fixedly connected to the top of the surface of the base 2, a slot 6 formed at the upper end of the base 2, an insert plate 7 fixedly connected to the lower end of the second connecting plate 5, and a bottom of the insert plate 7 fixedly connected to... A sealing gasket 8 is connected to a liquid pump 10 fixedly installed on one side of the top of the bracket 1. A liquid inlet pipe 12 and a serpentine pipe 14 are fixedly connected to the top of both sides of the cooling tank 23, respectively. A liquid storage tank 11 is fixedly connected to one side of the lower end of the bracket 1. A liquid extraction pipe 13 is fixedly connected to one side of the top of the liquid storage tank 11. A horizontal plate 15 is fixedly connected to the bottom of the inner wall of the bracket 1. Two fans 16 are fixedly installed at the center and one side of the bottom of the horizontal plate 15. The tops of the four fans 16 all extend to the outside of the horizontal plate 15. An upper pressure mold 20 is provided at the upper end of the lower pressure mold 3.

[0017] The top of the pressing mold 3 extends to the outside of the cooling tank 23. The bottom of the first connecting plate 4 contacts the top of the second connecting plate 5. The second connecting plate 5 is fixedly connected to the first connecting plate 4 by bolts. The bolt-fixed connecting plate structure realizes the detachable connection between the pressing mold 3 and the base 2, which not only ensures the stability of the pressing mold 3 during the pre-pressing process, but also facilitates the quick replacement of molds of different specifications to adapt to the diverse production needs of interior parts.

[0018] The number of support blocks 9 is set in several, and the upper ends of the support blocks 9 are in contact with the bottom of the lower mold 3. The multi-point support design disperses the pre-pressure borne by the lower mold 3 and avoids the mold from deforming due to long-term pressure.

[0019] Both the inner wall of the slot 6 and the insert plate 7 are frame-shaped structures. The lower end of the insert plate 7 extends into the interior of the slot 6 and contacts the inner wall of the slot 6, which facilitates the docking of the lower mold 3 and the base 2 during installation. The lower end of the sealing gasket 8 contacts the inner bottom of the slot 6 to prevent coolant from leaking from the joint between the lower mold 3 and the base 2.

[0020] The bottom of the suction pipe 13 extends into the interior of the liquid storage tank 11, and the top of the suction pipe 13 extends into the exterior of the bracket 1 and is fixedly connected to the suction end of the liquid pump 10 at the bottom. The bottom end of the inlet pipe 12 is fixedly connected to the inlet end of the liquid pump 10 at the top. One end of the serpentine pipe 14 extends into the exterior of the bracket 1 and is fixedly connected to the center of one side of the liquid storage tank 11, forming a closed-loop cooling circuit to realize continuous recycling of coolant. The top side of the front surface of the liquid storage tank 11 and the bottom side of the front surface are respectively fixedly connected to the injection pipe and the drain pipe. The front ends of the injection pipe and the drain pipe are threaded with caps. The injection pipe and the drain pipe are designed to facilitate quick replenishment or replacement of coolant. The cap sealing method takes into account both operational convenience and leakage prevention requirements to ensure the long-term reliability of the cooling system.

[0021] A cylinder 18 is fixedly installed at the center of the top of the frame 17. A piston rod is fixedly connected to the output end of the cylinder 18 at its bottom. The bottom of the piston rod extends through the outside of the frame 17 and is fixedly connected to a lifting plate 19. The top of the upper mold 20 is fixedly connected to the center of the bottom of the lifting plate 19. The cylinder 18 drives the lifting plate 19 to drive the upper mold 20 to move vertically, thereby realizing the mold closing and opening actions.

[0022] The inner walls of the frame 17 are provided with grooves 21 on both sides near the top. The center of both sides of the lifting plate 19 is fixedly connected with sliders 22. The opposite sides of the two sliders 22 extend into the interior of the two grooves 21 and slide to connect with the inner wall of the grooves 21. This prevents the upper pressure mold 20 from shifting laterally during the pre-pressing process, ensures the alignment accuracy of the upper and lower molds, and improves the molding quality of the product.

[0023] After pre-pressing is completed, the liquid pump 10 starts, drawing coolant from the storage tank 11 through the extraction pipe 13. The low-temperature coolant is then injected into the cooling tank 23 at the top of the base 2 through the inlet pipe 12. The coolant directly contacts the bottom and side walls of the lower mold 3, quickly absorbing heat from the mold and the pre-pressed product through heat conduction. The cooled coolant then flows out from the serpentine pipe 14 on the other side of the cooling tank 23. The serpentine pipe 14 extends the exposure path of the coolant in the air, and together with the forced airflow generated by the fan 16 at the bottom of the horizontal plate 15, accelerates the heat exchange between the coolant and the external environment, achieving initial cooling. The cooled coolant finally flows back to the storage tank 11, completing a single cycle.

[0024] In summary, this pre-pressing device for automotive interior processing, through the design of a base 2, slot 6, insert plate 7, sealing gasket 8, support block 9, liquid pump 10, liquid tank 11, liquid inlet pipe 12, liquid extraction pipe 13, serpentine pipe 14, and fan 16, uses the base 2 as the core support structure. The cooling groove 23 on its top provides a stable installation space for the lower pressing mold 3. Combined with the multiple support blocks 9 internally, it effectively disperses the pressure generated during the pre-pressing process, ensuring the stability of the lower pressing mold 3. The slot 6 and insert plate 7, together with the sealing gasket 8 at the bottom of the insert plate 7, seal the cooling groove 23, preventing coolant leakage and ensuring smooth cooling. The liquid pump 10 draws coolant from the liquid tank 11 through the liquid extraction pipe 13, and then... The coolant is injected into the cooling tank 23 through pipe 12 and then returned to the storage tank 11 through the serpentine pipe 14, forming a circulating cooling system. This system quickly removes the heat generated during the pre-pressing process, shortens the cooling time, and reduces the risk of material deformation due to prolonged high temperatures. At the same time, uniform cooling avoids localized thermal stress concentration, improving the dimensional accuracy and surface smoothness of the product. Meanwhile, the directional airflow generated by the fan 16 directly blows against the wall of the serpentine pipe 14, significantly enhancing the heat exchange efficiency between the coolant inside the serpentine pipe 14 and the external environment by accelerating the airflow speed outside the pipe. This gas-liquid synergistic cooling design improves the heat dissipation capacity of the serpentine pipe 14, thereby shortening the mold cooling cycle and avoiding the localized temperature stagnation problem that may be caused by simple liquid cooling, ensuring uniform cooling.
