[0024] The specific configuration and function of this embodiment are described in detail below. By designing the shape of the die member 18, the metal sealing ring can be stamped and formed at one time. The punch head 16 is driven downward by the connecting frame plate 12 through the upper die seat 14, so that the punch head 16 moves to the inside of the lower die seat 13. The material is moved to the die member 18 under the drive of the punch head 16 and covers the outer surface of the die member 18. Under the action of the impact force, the material is formed on the die member 18, so that the stamping of the metal sealing ring can be completed at one time. The metal sealing ring can be stamped without many steps, which saves a lot of time, not only reduces the processing efficiency of the metal sealing ring, but also The production cost is reduced, and at the same time, the material loss caused by multiple processing can be eliminated. Secondly, the connecting frame plate 12 drives the punch head 16 to move upward through the upper die base 14, and the punch head 16 will move out from the inside of the lower die base 13. At this time, the demolding power component 15 is operated, and the demolding power component 15 moves upward through the demolding connector 17. The demolding connector 17 drives the stripping annular plate 19 to move upward, so that the stripping annular plate 19 moves upward on the outer surface of the mold part 18, and then the metal sealing ring covering the outer surface of the mold part 18 can be pushed to move upward, so that the metal sealing ring can be separated from the surface of the mold part 18, and the mold part 18 can be demolded.

[0025] Embodiment 2

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the material guiding structure 2 comprises a material guiding inclined plate 21 and a bottom plate 24, a protective shell 23 is fixedly installed on the inclined end of the material guiding inclined plate 21, a cylinder 25 is fixedly installed on the upper end of the bottom plate 24, an assembling seat 26 is fixedly installed on one end of the bottom plate 24, an elastic thin plate 27 is fixedly installed on the upper end of the assembling seat 26, a lower pressure head 22 is fixedly installed on one end of the elastic thin plate 27, a supporting spring 28 is fixedly installed inside the cylinder 25, a limiting circular plate 29 is fixedly installed on the upper end of the supporting spring 28, the lower end of the lower pressure head 22 passes through the cylinder 25 and is fixed to the upper end of the limiting circular plate 29, one side of the material guiding inclined plate 21 is fixed to the inclined end of the assembling seat 26, the lower ends of the bottom plate 24 and the assembling seat 26 are fixed to the upper end of the lower die seat 13, and the lower pressure head 22 is located directly below the upper die seat 14.

[0027] The effect achieved by the entire embodiment is that, by providing the material guiding structure 2, when the upper die seat 14 moves downward, the upper die seat 14 will apply pressure to the lower pressure head 22, and the lower pressure head 22 will drive the elastic thin plate 27 to move. Since one end of the elastic thin plate 27 is limited to the upper end of the assembly seat 26, the elastic thin plate 27 generates an arc under the pressure of the lower pressure head 22, and at the same time, the lower end of the lower pressure head 22 pushes the limiting circular plate 29 to slide downward inside the cylinder 25, so that the limiting circular plate 29 applies pressure to the supporting spring 28 inside the cylinder 25, so that the supporting spring 28 is compressed inside the cylinder 25, which can press the elastic thin plate 27 to a suitable position, preventing the elastic thin plate 27 from interfering with the downward pressure of the upper die seat 14. After the upper die seat 14 is restored, the pressurized The elastic sheet 27 and the supporting spring 28 will release their own elastic force. At this time, the supporting spring 28 pushes the lower pressure head 22 to move upward through the limiting circular plate 29, and the elastic sheet 27 will also drive the lower pressure head 22 to move upward, so that the elastic sheet 27 returns to its original position, and the metal sealing ring after demoulding will be ejected and fall on the elastic sheet 27. Under the elastic force of the elastic sheet 27 itself, the metal sealing ring that falls on the elastic sheet 27 will be bounced away. Through the obstruction of the protective shell 23, the metal sealing ring will be guided to the material guide inclined plate 21 and enter the interior of the collection box along the material guide inclined plate 21, so that the metal sealing ring can be guided, so that the metal sealing ring will not fall on the lower die base 13 after stamping, so as to prevent the stamping of the metal sealing ring from being affected.

[0028] The use method and working principle of the device are as follows: First, by placing the material on the lower die base 13, the connecting frame plate 12 is driven by the external power system, and the connecting frame plate 12 drives the punch head 16 to move downward through the upper die base 14, so that the punch head 16 punches part of the material into the lower die base 13, and part of the material inside the lower die base 13 is pushed by the impact force, and the surface of the mold part 18 is covered and a metal sealing ring is formed, and then the connecting frame plate 12 is driven to move upward by the external power system, and the demoulding power component 15 is operated at the same time. The demoulding power assembly 15 drives the demoulding circular ring plate 19 to move upward through the demoulding connecting piece 17, so that the demoulding circular ring plate 19 separates the metal sealing ring covering the surface of the mold part 18, and pushes the metal sealing ring out of the lower mold base 13. Under the thrust, the metal sealing ring will bounce onto the elastic thin plate 27. Under the elastic force of the elastic thin plate 27 itself, the metal sealing ring can be bounced away, and with the cooperation of the protective shell 23, the metal sealing ring will be blocked and fall onto the material guide inclined plate 21, and then fall into the interior of the collection box through the material guide inclined plate 21.

[0029] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
