[0002] Stamping die technology has played a vital role in modern industrial development, particularly in the automotive connector manufacturing sector, where its applications are expanding rapidly. With the booming development of the new energy vehicle industry and advancements in high-speed data communication technology, the demand for various precision components has surged. Among these, circular needles, as a key component, play an irreplaceable role in ensuring product performance. This demand has driven stamping die technology towards higher precision and higher efficiency.

[0003] Currently, when processing small parts like round needles, the industry generally uses traditional cutting and stripping methods. The main methods include, but are not limited to: fixing the punch to the upper template and completing the cutting operation by moving it up and down. Traditional round needle stamping methods often have difficulty in handling the waste at the end of the stamping process, especially under the constraints of narrow spaces. Waste collection and handling often result in a bulky and cumbersome overall mold structure. Utility Model Content

[0004] To address the problems associated with stamping in the prior art, this application provides a stamping stripping device.

[0005] This application provides a stamping stripping device, which adopts the following technical solution:

[0006] A stamping stripping device includes an upper die base and a lower die base. A cutting head is horizontally arranged on the lower die base, and a placement groove is provided on the lower die base below the cutting head. A forming punch that cooperates with the cutting head is provided on the upper die base. A stripping mechanism for stripping is provided at the bottom of the placement groove. The stripping mechanism includes a stripping spring arranged on the lower die base. One end of the stripping spring is fixedly arranged on the lower die base, and the other end of the stripping spring is provided with a stripping component that abuts against the product.

A pressure structure that cooperates with the force-receiving structure is provided on the upper die base.

[0007] By adopting the above technical solution, the stamping stripping process is automated and highly efficient. During the stamping operation, the cooperation between the stripping spring and the stripping assembly effectively avoids waste residue while ensuring smooth product demolding. This design not only simplifies the mold structure but also significantly improves production efficiency and product quality. It is particularly suitable for machining precision parts in confined spaces, providing a reliable solution for the manufacturing of small parts such as round needles.

[0008] Preferably, a lower pad is also provided on the lower mold base, a stripping groove is provided on the lower pad, the stripping component is located in the stripping groove, a lower template is also provided above the lower pad, and the placement groove is located on the lower template.

[0009] By adopting the above technical solutions, the lower backing plate enhances the overall structural strength of the lower die base and provides installation space for the stripper groove, making the position of the stripper assembly more stable. The stripper groove provides movement space for the stripper assembly, ensuring a smooth and unobstructed stripping process. The addition of the lower die plate further optimizes the die structure layout, rationally arranging the placement slots on the lower die plate. This not only improves the space utilization of the die but also facilitates product positioning and placement, thereby enhancing the overall efficiency and accuracy of stamping stripping.

[0010] Preferably, a flexible block for protecting the cutting head is vertically slidably disposed in the placement groove.

[0011] By adopting the above technical solution, the flexible block can slide vertically in the placement groove, effectively protecting the cutting head from damage.

[0012] Preferably, the unloading mechanism includes an unloading plate and an unloading pin disposed in the unloading trough. The unloading pin is slidably disposed at the bottom of the placement trough and one end of it forms an abutment fit with the flexible block. The other end of the unloading pin forms an abutment fit with the unloading plate. The unloading plate is fixedly connected to one end of the unloading spring.

[0013] By adopting the above technical solution, the stripping mechanism consists of a stripping plate and a stripping pin. One end of the stripping pin abuts against the flexible block, and the other end abuts against the stripping plate. The stripping plate is connected to the stripping spring. This design can effectively utilize the elastic force of the stripping spring to ensure a smooth and reliable stripping process.

[0014] Preferably, the force-bearing structure includes a force-bearing rod slidably disposed on the lower template, one end of the force-bearing rod being fixedly connected to the stripper plate, and the other end of the force-bearing rod forming an abutment fit with the pressure structure.

[0015] By adopting the above technical solution, the stamping stripping device can achieve more stable force transmission during the stripping process. The design of the force rod makes the interaction between the stripping plate and the pressure structure more direct and precise, so that the stripping spring is compressed, thereby ensuring the reliability of the stripping action.

[0016] Preferably, an upper pad is horizontally arranged on the upper mold base, the forming punch is fixedly arranged on the upper pad, an upper template is horizontally arranged below the upper pad, the pressure structure is located on the upper template, a force-bearing gap is formed between the upper template and the upper pad, and the upper template and the upper pad can move relative to each other, and the forming punch passes through the upper template.

[0017] By adopting the above technical solution, the upper backing plate and upper die plate enable more precise position control of the forming punch during the stamping process. Simultaneously, the force gap and relative movement capability between the upper die plate and the upper backing plate effectively improve the device's adaptability to materials of varying thicknesses. Furthermore, the pressure structure, located on the upper die plate and cooperating with the force-bearing structure, further optimizes the force transmission efficiency during the stripping process, ensuring a smoother and more reliable stripping action. In summary, this solution significantly improves the working accuracy and stability of the stamping stripping device, while also expanding its applicability.

[0018] Preferably, a pressure torque spring is provided on the upper mold base, and a connecting rod is fixedly provided at one end of the pressure torque spring. The connecting rod passes through the lower pad and is fixedly connected to the lower mold plate.

[0019] By adopting the above technical solution, the setting of the pressure torque spring can provide stable elastic support for the upper mold base, and the introduction of the connecting rod realizes a solid connection between the upper mold base and the lower mold base, ensuring the reliability of the overall structure, while simplifying the assembly and maintenance process of the device.

[0020] Preferably, the pressure structure includes a pressure block disposed on the upper template, and the pressure block forms an abutting fit with one end of the force-bearing rod.

[0021] By adopting the above technical solution, the pressure block is set on the upper die plate and forms an abutment fit with one end of the force-bearing rod. This allows the pressure block to accurately act on the force-bearing rod when the upper die plate moves downward during the stamping process, thereby driving the stripping mechanism to store force. This design ensures the stability of the stripping process, improves stripping efficiency, and reduces the possibility of waste residue.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1.

[0029] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail.

[0030] This application discloses a stamping stripping device.

[0031] Reference Figure 1 and Figure 2 A stamping stripping device includes an upper die base 1 and a lower die base 2. A cutting head 3 is horizontally arranged on the lower die base 2, and a placement groove 4 is arranged on the lower die base 2 below the cutting head 3. A forming punch 5 that cooperates with the cutting head 3 is arranged on the upper die base 1. A stripping mechanism 6 for stripping is arranged at the bottom of the placement groove 4. This device achieves efficient stripping within a limited space and solves the problem of bulky molds caused by traditional stripping methods through optimized structural design.

[0032] Reference Figure 1 and Figure 2 The lower mold base 2 is provided with a lower pad 7, and a lower template 8 is fixedly provided on the lower pad 7. The cutting head 3 is horizontally provided on the surface of the lower template 8. The placement groove 4 is opened on the lower template 8 below the cutting head 3. A flexible block 9 for protecting the cutting head and ejecting waste material is slidably provided in the placement groove 4. The ejection mechanism 6 includes an ejection spring 601 provided on the lower mold base 2. An ejection assembly 602 is fixedly provided at one end of the ejection spring 601. The ejection assembly 602 includes an ejection plate 6021 and an ejection pin 6022 provided in the ejection groove. The ejection pin 6022 is vertically slidably provided at the bottom of the placement groove 4. The ejection plate 6021 is located below the ejection pin 6022 and is horizontally provided in the ejection groove. One end of the ejection pin 6022 forms an abutment with the flexible block 9, and the other end forms an abutment with the ejection plate 6021. One end of the ejection spring 601 is fixedly provided on the lower mold base 2, and the other end is fixedly connected to the ejection plate 6021.

[0033] Reference Figure 1 and Figure 2 An upper pad 10 is horizontally fixed below the upper mold base 1. A forming punch 5 is fixedly fixed on the upper pad 10. An upper template 11 is also horizontally fixed below the upper pad 10. A pressure torque spring 12 is fixedly installed on the upper mold base 1. One end of the pressure torque spring 12 is connected to a connecting rod 13. The connecting rod 13 passes through the lower pad 7 and is fixedly connected to the lower template 8.

[0034] Reference Figure 1 and Figure 2 A force-bearing gap 14 is formed between the upper template 11 and the upper pad 10, and the upper template 11 and the upper pad 10 can move relative to each other. The forming punch 5 passes through the upper template 11. The size of the force-bearing gap 14 should be designed according to the stamping stroke. This design ensures the free movement of the upper template 11 and avoids instability caused by excessive gap. A pressure structure 15 is provided on the upper template 11. The pressure structure 15 includes a pressure block 1501 provided on the upper template 11. A force-bearing structure 16 for the contraction of the stripping spring 601 is provided on the stripping assembly 602. The force-bearing structure 16 includes a force-bearing rod 1601 that is vertically inserted into the lower template 8. One end of the force-bearing rod 1601 is fixedly connected to the stripping assembly 602.

[0035] The implementation principle of this embodiment is as follows: First, the upper mold base 1 is pressed down. After the pressure block 1501 abuts against the force rod 1601, the stripper plate 6021 moves downward in the stripper groove. The stripper spring 601 contracts and stores force, and the stripper pin 6022 and flexible block 9 both descend. When the stripper plate 6021 reaches the bottom of the stripper groove, the upper mold base 1 continues to press down. At this time, the pressure torque spring 12 contracts, the force gap 14 decreases, and the forming punch 5 presses down on the product to cut it on the cutting head 3. After the cutting is completed, the lower mold base 2 resets, and then the stripper spring 601 extends and retracts, driving the stripper plate 6021 and stripper pin 6022 to rise, so that the flexible block 9 ejects the waste. By integrating the stripper mechanism 6 into the bottom of the placement groove 4, the internal space of the mold is fully utilized, avoiding the problem of additional mold volume. At the same time, through the cooperation of the stripper spring 601 and the force structure 16, the automatic discharge of waste is realized, improving production efficiency and product quality. The elasticity and high temperature resistance of the flexible block 9 can absorb the impact force generated during the stamping process, thus preventing the cutting head 3 from being damaged due to excessive wear.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
