Description

Technical Field

[0001] This utility model relates to the field of skin processing mold technology, and in particular to a side panel skin processing mold. Background Technology

[0002] In industrial sectors such as automobile manufacturing, side panel skins are crucial body coverings, and their processing quality directly impacts a vehicle's appearance and performance. Traditional side panel skin processing often employs manual hammering or simple molds, resulting in low efficiency and difficulty in ensuring product consistency and precision, leading to assembly difficulties and appearance defects. With the trend towards lightweighting and increasingly complex automotive designs, higher demands are being placed on the shape accuracy, surface quality, and production efficiency of side panel parts.

[0003] However, existing stamping or bending dies often suffer from drawbacks such as complex structure, high cost, inconvenient adjustment, or low automation. Especially in skin forming on bending machines, specific challenges include: uneven force during die operation may cause slight displacement, affecting forming accuracy; after forming, vacuum adsorption or mechanical interlocking between the skin and the die makes it difficult for traditional ejector pins to effectively and smoothly eject the workpiece, easily causing scratches or deformation on the workpiece surface. Therefore, a side panel skin processing die is needed. Utility Model Content

[0004] Based on the existing technical problems, this utility model proposes a side panel skin processing mold.

[0005] This utility model proposes a side panel skin processing mold, including an upper mold and a lower mold. The upper mold is installed on the hydraulic system drive end of the bending machine, and the lower mold is installed on the worktable of the bending machine. The upper mold moves downward and performs an extrusion forming operation with the skin placed on top of the lower mold. The upper mold includes an extrusion mold base, and a groove is opened on the top side of the extrusion mold base. The inner wall of the groove is slidably inserted into the surface of the clamping block of the bending machine.

[0006] The lower die includes a forming die base, and the extrusion die base is located above the forming die base. A drive groove is provided on the top of the forming die base.

[0007] Preferably, a connecting seat is fixedly installed on the left side of the extrusion die base, and a limit plate is fixedly installed on the left side of the connecting seat.

[0008] Preferably, a cavity seat is also fixedly installed between the limiting plate and the extrusion mold base. The cavity seat is located below the connecting seat, and the bottom of the cavity seat and the bottom of the extrusion mold base form a forming groove.

[0009] Preferably, the bottom of the forming mold base is fitted with a mounting base, which is located on the worktable of the bending machine and is positioned and installed by a limiting mounting mechanism on the worktable of the bending machine.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A side panel skin processing mold includes an upper mold 1 and a lower mold 2. The upper mold 1 is installed on the hydraulic system drive end of a bending machine, and the lower mold 2 is installed on the worktable of the bending machine. The upper mold 1 moves downward to perform an extrusion forming operation with the skin placed on top of the lower mold 2. The upper mold 1 includes an extrusion mold base 11. A groove 12 is opened on the top side of the extrusion mold base 11. The inner wall of the groove 12 is slidably inserted into the surface of the clamping block of the bending machine. A connecting seat 13 is fixedly installed on the left side of the extrusion mold base 11, and a limit plate 14 is fixedly installed on the left side of the connecting seat 13.

[0024] A cavity seat 15 is also fixedly installed between the limiting plate 14 and the extrusion mold base 11. The cavity seat 15 is located below the connecting seat 13, and the bottom of the cavity seat 15 and the bottom of the extrusion mold base 11 form a molding groove.

[0025] Specifically, the forming groove, which is formed by the bottom of the cavity seat 15 and the bottom of the extrusion mold seat 11, clearly defines the area and initial shape of the skin being extruded and formed. The main function of the limiting plate 14 is to limit the movement laterally, but the presence of the cavity seat 15 and the forming groove formed by it and the extrusion mold seat 11 ensure that the shape and size of the upper mold 1 in the vertical direction are also accurate and stable.

[0026] The lower die 2 includes a forming die base 21, an extrusion die base 11 located above the forming die base 21, and a drive groove 22 is provided on the top of the forming die base 21; a mounting base 23 is inserted into the bottom of the forming die base 21 and is located on the worktable of the bending machine, and is positioned and installed by the limiting mounting mechanism on the worktable of the bending machine.

[0027] Specifically, the forming mold base 21 constitutes the main body of the lower mold 2, and together with the forming groove of the upper mold 1, it forms the extrusion mold base 11 and the cavity base 15 to complete the final forming of the skin.

[0028] A mating base 24 is installed on the left inner wall of the drive groove 22. An elastic hole 25 is opened on the bottom wall of the drive groove 22 at the right end of the mating base 24. A spring 26 is installed on the inner wall of the elastic hole 25. Multiple springs 26 are arranged linearly on the inner wall of the drive groove 22.

[0029] Specifically, spring 26 ensures that the component automatically springs back to its initial position after each stamping, preparing for the next stamping. This guarantees the reliability and consistency of the operation. After forming, the rebound force of spring 26 can be used to eject the formed skin from the lower die 2 or upper die 1, or to assist the ejector device in its operation, making part removal more convenient and faster, realizing automated or semi-automated operation, and improving production efficiency. Multiple linearly arranged springs 26 can provide a more uniform and stronger ejection force.

[0030] Each of the multiple springs 26 has a sliding seat 27 fixedly mounted on its top. The two sides of the sliding seat 27 are slidably inserted into the right end of the mating base 24 and the left inner wall of the drive groove 22, respectively.

[0031] Specifically, the sliding engagement between the sliding seat 27 and the inner wall of the mating base 24 and the drive groove 22 provides precise guidance for the movement of the spring 26. This ensures that when the spring 26 is compressed or extended, it will only move along the preset vertical direction or the main force direction, without lateral deviation.

[0032] The inner bottom wall of the drive groove 22 is also fixedly installed with a limiting base 28. The two limiting bases 28 are located on both sides of the spring 26 and are also located at the bottom of the sliding seat 27.

[0033] Specifically, the most direct function of the limiting base 28 is to limit the range of movement of the sliding seat 27; to limit the maximum downward movement of the sliding seat 27, preventing it from excessively compressing the spring 26 or hitting the bottom of the drive groove 22, thus protecting the spring 26 and preventing damage to the mechanism.

[0034] The side panel skin processing mold is ingeniously designed, integrating multiple details to enhance performance. The upper mold 1 is connected to the bending machine via the slide 12, and together with the connecting seat 13 and the limiting plate 14, ensures the ease of installation and lateral stability of the upper mold 1. The forming groove formed by the cavity seat 15 and the extrusion die seat 11 precisely defines the skin forming area and initial shape, and enhances the vertical rigidity of the upper mold 1, ensuring forming accuracy. The forming die seat 21 and the limiting mounting seat 23 of the lower mold 2 enable fast and accurate positioning and installation, improving production efficiency and stability.

[0035] The design of the mating base 24, linearly arranged springs 26, and sliding seat 27 within the drive slot 22 constitutes a highly efficient and reliable elastic mechanism. Spring 26 provides an automatic reset function, ensuring consistent action; its rebound force effectively ejects the molded skin, enabling automated part removal and significantly improving efficiency. The precise sliding engagement of the sliding seat 27 with both sides provides stable guidance for the movement of spring 26, preventing deviation. The bottom limiting base 28 strictly controls the stroke of the sliding seat 27, preventing overload of spring 26, protecting the mechanism, and ensuring the accuracy of the reset position.

[0036] In summary, this mold design, through precise structural matching, achieves high-precision, high-efficiency, and high-stability skin processing, improves product quality, simplifies operation, and extends mold life, demonstrating good practical value and economic benefits.

[0037] Working Principle: Die Installation and Positioning: Upper Die 1 Installation: The slide groove 12 at the top of the extrusion die holder 11 slides into the clamping block at the hydraulic drive end of the bending machine, achieving initial positioning. Subsequently, the entire upper die 1 is fixed to the drive end. The connecting seat 13 and the limiting plate 14 ensure the precise position and stability of the upper die 1 in the lateral direction. The forming groove formed by the cavity seat 15 and the extrusion die holder 11 constitutes the forming surface of the upper die 1. Lower Die 2 Installation: The mounting seat 23 at the bottom of the forming die holder 21 is precisely positioned and securely installed by the limiting mounting mechanism on the bending machine worktable. At this time, the forming surface of the lower die 2 is ready to receive the skin.

[0038] Preparing for stamping: The operator places the side panel to be formed on the forming surface of the lower die 2, ensuring its correct positioning. The hydraulic system of the bending machine is ready to start. The hydraulic system of the bending machine drives the upper die 1 to move downward. The forming groove of the upper die 1 moves downward, working together with the forming surface of the lower die 2 to extrude the panel placed in the middle.

[0039] During the extrusion process, the skin is forced to conform to the cavities of the upper and lower dies 2, undergoing plastic deformation to ultimately form the desired side panel skin shape. Simultaneously, the extrusion die holder 11 of the upper die 1 exerts downward pressure on the sliding seat 27 connected to the spring 26 within the drive groove 22, compressing the spring 26. When the upper die 1 completes its extrusion stroke and reaches the predetermined position, the bending machine's hydraulic system drives the upper die 1 to return upwards. The upper die 1 leaves the lower die 2, and the formed skin remains on the lower die 2. As the upper die 1 rises and the pressure is released, the compressed spring 26 begins to rebound. The rebound force of the spring 26 pushes or lifts the skin upwards through the sliding seat 27, separating it from the surface of the lower die 2 for easy removal. Multiple linearly arranged springs 26 provide uniform and sufficient ejection force.

[0040] The limiting base 28 restricts the upward travel of the sliding seat 27 and the spring 26, ensuring the spring returns to its original position and preventing the spring 26 from popping out. The spring 26 returns to its initial position, and the sliding seat 27 also returns to its starting state, preparing for the next stamping cycle. The operator removes the formed skin, places a new skin, and prepares for the next stamping cycle.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
