[0002] Traditional stamping dies typically use mechanical ejection devices (such as ejector pins, ejector plates, etc.) to demold after blanking, which has the following technical drawbacks:

[0003] 1. Product damage issue: The mechanical ejection mechanism is in direct contact with the product, which can easily cause surface scratches;

[0004] 2. Deformation problem: Thin-walled parts are prone to plastic deformation under mechanical stress during the ejection process;

[0023] 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.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a vacuum adsorption stripping mold structure, including an upper mold 1 and a lower mold 2. The upper mold 1 and lower mold 2 are internally provided with opposing upper mold inserts 10 and lower mold inserts 20. Several corrugated suction cups 3 are embedded inside the upper mold insert 10, and these corrugated suction cups 3 are connected to an external vacuum generator via an air pipe connector 4. When the upper mold 1 and lower mold 2 are closed, the stamping surfaces of the upper mold inserts 10 and lower mold inserts 20 punch the raw metal sheet to form a product, which is then adsorbed and lifted by the corrugated suction cups 3. Through the design of the upper mold insert 10 and the corrugated suction cups 3, the punching and adsorption actions are integrated, avoiding product scratches caused by traditional mechanical ejection. The deep integration of the vacuum adsorption system with the mold structure solves the problem of deformation and detachment of thin-walled parts after stamping.

[0025] Please see Figure 2 , Figures 4-5 The upper mold 1 includes, from top to bottom, a top plate 11, an upper mold base 12, an upper backing plate 13, a stripper plate 14, and an upper template 15. The top plate 11 is connected to the upper mold base 12 by pins, and the upper mold base 12, upper backing plate 13, stripper plate 14, and upper template 15 are connected by pins. The upper mold insert 10, stripper plate 14, and upper template 15 are also connected by pins. Precise positioning using pins ensures the alignment accuracy of each template.

[0026] An inner plate 16 is embedded in the lower part of the upper die holder 12. Several return springs 17 are provided on the upper part of the inner plate 16. The lower ends of the return springs 17 abut against the upper part of the inner plate 16, and the upper ends pass through the upper die holder 12 and abut against the lower part of the top plate 11. The return springs 17 and the inner plate together form a buffer system to effectively absorb the punching vibration energy.

[0027] The upper pad 13 has a channel structure 130 inside for the vacuum pipe 5 to be connected. The upper end of the air pipe connector 4 is connected to the vacuum pipe 5 through the channel structure 130, and the lower end passes through the stripper plate 14 and is connected to the corrugated suction cup 3 embedded in the upper mold insert 10. This allows the vacuum pipe 5 on the external vacuum generator to be connected to the mold contents. The channel structure 130 effectively houses the vacuum pipe 5 and prevents it from being damaged by the mold closing and opening movements. The through connection of the air pipe connector 4 enables lossless air transmission between the vacuum generator and the suction cup.

[0028] The upper mold insert 10 has a fixing hole 100 on its upper part that matches the lower end of the air pipe connector 4, and a fixing hole 101 on its lower part that matches the upper end of the corrugated suction cup 3. The fixing hole 100 securely fixes the air pipe connector 4, preventing displacement or other adverse factors affecting air pressure due to mold closing and opening movements. The fixing hole 101 securely fixes the corrugated suction cup 3, preventing displacement or other adverse factors affecting product adsorption due to mold closing and opening movements. The upper mold plate 15 has an opening structure that matches the lower mold insert 20. This contoured opening structure ensures sufficient space for insert movement and avoids interference during mold closing.

[0029] Please see Figures 3-5 The lower mold 2 includes a lower mold base 21, a lower pad 22, and a lower template 23 arranged sequentially from bottom to top; the lower mold insert 20, the lower mold base 21, and the lower pad 22 are connected by pins, and the pins are used for precise positioning to ensure the alignment accuracy of each template.

[0030] A guide post 24 is provided on the upper part of the lower mold base 21. The upper end of the guide post 24 passes through the lower pad 22 and the lower template 23 and cooperates with the upper mold 1. The guide post 24 provides precise positioning to ensure the alignment accuracy of the upper mold insert and the lower mold insert during mold closing. The lower mold insert 20 is located on the upper part of the lower pad 22. The lower template 23 has an opening structure that matches the lower mold insert 20. The contoured opening structure ensures the movement space of the insert and avoids interference during mold closing.

[0031] The upper part of the lower die base 21 is provided with several return springs 25 and several return springs 26. The lower end of the return spring 25 abuts against the inside of the lower die base 21, and the other end passes through the lower pad 22 and abuts against the bottom of the lower template 23. The combination of the return springs 25 and the lower template 23 forms a buffer system, which effectively absorbs the punching vibration energy.

[0032] The lower end of the return spring 26 abuts against the lower die base 21, and the upper end passes through the lower pad 22 and is connected to the fixed rod 27. The upper end of the fixed rod 27 passes through the lower die plate 23. Several return springs 26 and fixed rods 27 are combined to form a lifting structure or a positioning structure. The lifting structure lifts the blanking material metal plate, and the positioning structure establishes a stamping station for the material metal plate.

[0033] Working Principle: The upper die 1 is fixed to the stamping device via the top plate 11. Under the drive of the stamping device, the upper die 1 moves downwards for stamping. When the upper die 1 and lower die 2 are closed, the stamping surfaces of the upper die insert 10 and lower die insert 20 punch the raw metal sheet to form the product. The corrugated suction cup 3 simultaneously adsorbs the product surface. When the die is closed, the external vacuum generator is activated immediately, and the punching and forming and vacuum adsorption are completed simultaneously, realizing the integrated action of punching and adsorption, avoiding product scratches caused by traditional mechanical ejection. When the upper die 1 and lower die 2 are opened, the corrugated suction cup 3 moves upwards with the upper die 1, and the product is subsequently picked up and transferred to the corresponding position, or the product is removed from the corrugated suction cup 3 by the operator and placed in the finished product area. The next round of punching and forming process then begins.
