Description

Technical Field

[0001] This utility model relates to the field of automotive interior technology, specifically to a wood veneer automotive interior parts molding equipment. Background Technology

[0002] Automotive interiors mainly refer to automotive products used for interior modifications, covering all aspects of the car's interior, such as steering wheel covers, car seat cushions, car floor mats, car perfumes, car pendants, interior decorations, storage boxes, etc. Among them, foamed products provide a comfortable feeling and greater safety assurance. They are made by injecting raw material A and raw material B under certain pressure between the surface and the frame, reacting at a certain temperature, and then shaping them according to our requirements.

[0003] Traditional wood veneer automotive interior parts are mostly manufactured using hot pressing molding processes, which have the following drawbacks: uneven wood veneer bonding: air bubbles and wrinkles are easily generated when manually laying wood veneer, resulting in misalignment or damage of the texture; poor flexibility: the mold is fixed with a single texture and cannot adapt to the needs of multi-variety small-batch production. Therefore, we have proposed a wood veneer automotive interior parts molding equipment to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a wood veneer texture automotive interior parts molding equipment, which solves the problems mentioned in the background art.

[0006] The stamping structure is used for stamping the substrate and the wood veneer, and the vacuum adsorption structure is used for tightly adsorbing the wood veneer.

[0007] By adopting the above technical solution, the design of the T-slot and the T-shaped limiting rod makes the output end of the stamping cylinder drive the hot pressing plate to move downward more stably, and at the same time limits the hot pressing plate.

[0008] Furthermore, the stamping structure includes a stamping cylinder, a limiting plate, a T-shaped limiting rod, and a vibration auxiliary structure. The stamping cylinder is fixedly installed at the center of the upper surface of the connecting plate. The output end of the stamping cylinder penetrates the interior of the connecting plate. The limiting plate is fixedly connected to the outer wall of the output end of the stamping cylinder. T-shaped limiting rods are fixedly connected to both ends of the limiting plate. The output end of the stamping cylinder is provided with a vibration auxiliary structure.

[0009] The vibration-assisted structure is used to facilitate the migration and discharge of residual bubbles towards the edge.

[0010] Furthermore, the vibration-assisted structure includes a fixed plate, a U-shaped groove, a hot-pressing plate, an annular plate, a rectangular cavity, a groove, and a miniature ultrasonic generator. The output end of a stamping cylinder is fixedly connected to the center of the upper surface of the fixed plate. A U-shaped groove is formed near the edge of the lower surface of the fixed plate. A hot-pressing plate is fixedly installed on the lower surface of the fixed plate. An annular plate is fixedly connected to the outer wall of the hot-pressing plate. A rectangular cavity is formed inside the hot-pressing plate. A groove is formed near the rectangular cavity inside the hot-pressing plate. There are several grooves. A miniature ultrasonic generator is fixedly installed inside each groove.

[0011] Furthermore, the vacuum adsorption structure includes a fixed frame, a U-shaped sealing frame, a limiting groove, a magnetic component one, a texture module, negative pressure suction holes, a magnetic component two, a connecting pipe, and a vacuum pump. The bottom of the fixed frame is fixedly installed on the upper surface of the workbench. The U-shaped sealing frame is fixedly connected to the upper surface of the fixed frame. A limiting groove is opened on the inner side of the upper surface of the fixed frame. A magnetic component one is fixedly installed inside the limiting groove. A texture module is placed inside the fixed frame. Several negative pressure suction holes are opened inside the texture module. A magnetic component two is fixedly installed on the outer wall of the texture module. A connecting pipe is fixedly connected to the bottom end of the fixed frame. The bottom end of the connecting pipe extends to the lower surface of the workbench. A vacuum pump is fixedly connected to the bottom end of the connecting pipe. The vacuum pump is fixedly installed on the lower surface of the workbench.

[0012] Furthermore, the miniature ultrasonic generator is encased in a zirconia ceramic shell, and is electrically connected to a PLC controller, a stamping cylinder, and a vacuum pump.

[0013] By adopting the above technical solution, the miniature ultrasonic generator is encased in a zirconia ceramic shell, which can withstand temperatures up to 300 degrees Celsius, and is filled with silicon nitride thermally conductive adhesive.

[0014] Furthermore, the T-shaped limiting rod is movably connected inside the T-shaped groove. The first magnetic component is a permanent magnet with its N pole facing the mounting surface, and the second magnetic component is a permanent magnet with its S pole facing the mating surface. The two are attracted and fixed by the cooperation of opposite magnetic poles. The size of the U-shaped groove is adapted to the size of the U-shaped sealing frame.

[0015] The beneficial effects of this utility model are:

[0016] 1. This wood veneer automotive interior trim molding equipment, through the setting of a stamping and forming structure and a vacuum adsorption structure, when the hot press plate presses down on the substrate and wood veneer, the PLC controller starts the vacuum pump. The vacuum pump tightly adsorbs the wood veneer on the inner wall of the texture module through the connecting pipe and negative pressure suction hole, avoiding air bubbles and blurring of the texture. At the same time, the wood veneer fills the texture of the inner wall of the texture module in the hot press plate's softened state. Simultaneously, the PLC controller starts the micro ultrasonic generator. Honeycomb-shaped grooves are opened inside the hot press plate, and each groove is embedded with a micro ultrasonic generator, forming a six-by-six matrix energy field coverage to ensure uniform vibration. By vibrating the micro ultrasonic generator during the hot pressing process, air is expelled, ensuring that there are no air bubbles between the wood veneer and the substrate, thereby improving the bonding quality.

[0017] 2. This wood veneer automotive interior parts molding equipment, through the setting of a vacuum adsorption structure, allows workers to wrap a temporary coil around the magnetic part and pass a reverse pulse current when the texture module needs to be replaced. This briefly weakens the residual magnetism, allowing the texture module to be directly removed from the inside of the fixed frame for quick replacement. Through the above method, reliable separation can be achieved without damaging the magnetic part, while ensuring reusability. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1-5 A wood veneer texture automotive interior parts forming equipment includes a workbench 1, with support plates 2 fixedly connected to both ends of the upper surface of the workbench 1, a connecting plate 3 fixedly connected to the top of the support plate 2, a stamping forming structure 4 on the outer wall of the connecting plate 3, a vacuum adsorption structure 5 on the upper surface of the workbench 1, a T-slot 6 on the outer wall of the support plate 2, and a PLC controller 7 fixedly installed on the outer wall of the support plate 2.

[0027] The stamping structure 4 is used for stamping the substrate and the wood veneer, and the vacuum adsorption structure 5 is used for tightly adsorbing the wood veneer. By adopting the above technical solution, the design of the T-groove 6 and the T-shaped limiting rod 43 makes the output end of the stamping cylinder 41 drive the hot press plate 443 to move downward more stably, and also limits the hot press plate 443.

[0028] Reference Figure 1-4 As shown, the stamping structure 4 includes a stamping cylinder 41, a limiting plate 42, a T-shaped limiting rod 43, and a vibration auxiliary structure 44. The stamping cylinder 41 is fixedly installed at the center of the upper surface of the connecting plate 3. The output end of the stamping cylinder 41 passes through the interior of the connecting plate 3. The limiting plate 42 is fixedly connected to the outer wall of the output end of the stamping cylinder 41. The T-shaped limiting rod 43 is fixedly connected to both ends of the limiting plate 42. The vibration auxiliary structure 44 is provided at the output end of the stamping cylinder 41.

[0029] The vibration-assisted structure 44 is used to discharge residual bubbles by migrating them to the edge.

[0030] It should be noted that the stamping cylinder 41 is a bidirectional cylinder. The inlet and outlet ends of the stamping cylinder 41 are connected to the air inlet of one side of the external reversing valve through compressed air pipes. The air inlet of the other side of the reversing valve is connected to the air inlet of the external air pump through compressed air pipes. In addition, the air control terminal of the reversing valve is connected to the control output terminal of the PLC controller 7 through a cable. Therefore, the PLC controller 7 controls the reversing valve to switch the air supply and exhaust direction in the stamping cylinder 41, thereby realizing the extension and retraction of the output end of the stamping cylinder 41. The stamping cylinder 41 is mounted on the connecting plate 3. The control terminal of the PLC controller 7 is controlled by the external power supply control equipment through a wiring harness.

[0031] Reference Figure 1-4 As shown, the vibration auxiliary structure 44 includes a fixed plate 441, a U-shaped groove 442, a hot press plate 443, an annular plate 444, a rectangular cavity 445, a groove 446, and a miniature ultrasonic generator 447. The output end of a stamping cylinder 41 is fixedly connected to the center of the upper surface of the fixed plate 441. A U-shaped groove 442 is formed near the edge of the lower surface of the fixed plate 441. A hot press plate 443 is fixedly installed on the lower surface of the fixed plate 441. An annular plate 444 is fixedly connected to the outer wall of the hot press plate 443. A rectangular cavity 445 is formed inside the hot press plate 443. A groove 446 is formed near the rectangular cavity 445 inside the hot press plate 443. There are several grooves 446. A miniature ultrasonic generator 447 is fixedly installed inside each groove 446. The structure is formed by stamping and vacuum adsorption. In configuration 5, when the hot press plate 443 presses down on the substrate and the wood veneer, the PLC controller 7 starts the vacuum pump 59. The vacuum pump 59 tightly adsorbs the wood veneer on the inner wall of the texture module 55 through the connecting pipe 58 and the negative pressure suction hole 56, avoiding air bubbles and blurring of the texture. At the same time, the wood veneer fills the texture of the inner wall of the texture module 55 under the softened state of the hot press plate 443. Simultaneously, the PLC controller 7 starts the micro ultrasonic generator 447. A honeycomb-shaped groove 446 is opened inside the hot press plate 443, and each groove 446 is embedded with a micro ultrasonic generator 447, forming a six-by-six matrix energy field coverage to ensure uniform vibration. By vibrating the micro ultrasonic generator 447 during the hot pressing process, air is expelled, ensuring that there are no air bubbles between the wood veneer and the substrate, thereby improving the bonding quality.

[0032] Reference Figure 1 , 2As shown in Figures 3 and 5, the vacuum adsorption structure 5 includes a fixed frame 51, a U-shaped sealing frame 52, a limiting groove 53, a magnetic component 54, a texture module 55, negative pressure suction holes 56, a magnetic component 57, a connecting pipe 58, and a vacuum pump 59. The bottom of the fixed frame 51 is fixedly installed on the upper surface of the workbench 1. The U-shaped sealing frame 52 is fixedly connected to the upper surface of the fixed frame 51. A limiting groove 53 is opened on the inner side of the upper surface of the fixed frame 51. A magnetic component 54 is fixedly installed inside the limiting groove 53. The texture module 55 is placed inside the fixed frame 51. Several negative pressure suction holes 56 are opened inside the texture module 55. A magnetic component 57 is fixedly installed on the outer wall of the texture module 55. The second component 57 has a connecting pipe 58 fixedly connected to the bottom end of the fixed frame 51. The bottom end of the connecting pipe 58 extends to the lower surface of the worktable 1, and the bottom end of the connecting pipe 58 is fixedly connected to a vacuum pump 59, which is fixedly installed on the lower surface of the worktable 1. With the setting of the vacuum adsorption structure 5, when the texture module 55 needs to be replaced, the operator wraps a temporary coil around the magnetic component and applies a reverse pulse current to briefly weaken the residual magnetism. In this way, the texture module 55 can be directly removed from the inside of the fixed frame 51 for quick replacement. Through the above scheme, reliable separation can be achieved without damaging the magnetic component, while ensuring reusability.

[0033] Reference Figure 1-4 As shown, the miniature ultrasonic generator 447 is encased in a zirconia ceramic shell. The miniature ultrasonic generator 447 is electrically connected to the PLC controller 7, the PLC controller 7 is electrically connected to the stamping cylinder 41, and the PLC controller 7 is electrically connected to the vacuum pump 59. By adopting the above technical solution, the miniature ultrasonic generator 447, encased in a zirconia ceramic shell, can withstand temperatures up to 300 degrees Celsius, and is filled with silicon nitride thermally conductive adhesive.

[0034] Reference Figure 1-3 As shown, the T-shaped limiting rod 43 is movably connected inside the T-shaped groove 6. The first magnetic component 54 is a permanent magnet with the N pole facing the mounting surface, and the second magnetic component 57 is a permanent magnet with the S pole facing the mating surface. The two are attracted and fixed by the cooperation of opposite magnetic poles. The size of the loop groove 442 is adapted to the size of the loop sealing frame 52.

[0035] In use, the veneer and substrate to be processed are placed sequentially inside the texture module 55. Then, the PLC controller 7 starts the punching cylinder 41. The punching cylinder 41 drives the limiting plate 42, T-shaped limiting rod 43 and vibration auxiliary structure 44 to move downward along the T-slot 6 through the output end, so that the hot pressing plate 443 at the bottom of the fixing plate 441 enters the interior of the texture module 55. At the same time, the outer wall of the loop sealing frame 52 enters the interior of the loop groove 442 for limiting, so that the hot pressing plate 443 presses down on the substrate and veneer. The PLC controller 7 starts the vacuum pump 59, which connects to the negative pressure suction hole through the connecting pipe 58. The wood veneer on the inner wall of the texture module 55 is tightly adsorbed to avoid air bubbles and blurred texture. At the same time, the wood veneer fills the texture of the inner wall of the texture module 55 under the softened state of the hot press plate 443. Simultaneously, the micro ultrasonic generator 447 is activated by the PLC controller 7. Honeycomb grooves 446 are opened inside the hot press plate 443, and each groove 446 is embedded with a micro ultrasonic generator 447, forming a six-by-six matrix energy field coverage to ensure uniform vibration. By vibrating the micro ultrasonic generator 447 during the hot pressing process, air is expelled to ensure that there are no air bubbles between the wood veneer and the substrate, thereby improving the bonding quality.
