Abstract
Description
Technical Field
[0001] This application relates to the field of stamping die technology, and more specifically, to an FPC stamping die. Background Technology
[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing them to undergo plastic deformation or separation, thereby obtaining workpieces (stamped parts) of the required shape and size. In the processing of FPC, when using stamping to separate the panels, the product needs to be removed from the die. The current method is to set up a separate suction cup to pick up the product from the lower die surface and place it in a tray to hold the separated product. However, whenever the production line is changed, in addition to installing the die, time is also needed to install and adjust the position of the suction cup, which is time-consuming and labor-intensive. Summary of the Invention
[0003] The purpose of this application is to provide an FPC stamping die that can solve the technical problem that the current method of removing products from the die by separately setting up a suction cup to pick up the product is time-consuming and laborious when installing and adjusting the position of the suction cup.
[0004] This application provides an FPC stamping die, including an upper die base and a lower die base disposed below the upper die base. A punch holder is fixedly disposed at the lower end of the upper die base, and a punch is fixedly disposed on the punch holder. A stripper plate is disposed below the punch holder, and an elastic element is disposed between the punch holder and the stripper plate. A vacuum tube and a suction nozzle connected to the vacuum tube are embedded in the stripper plate. The suction nozzle penetrates the bottom of the stripper plate. A die cavity is fixedly disposed at the upper end of the lower die base. The die cavity has a first through hole and a second through hole. The punch slides through the stripper plate and cooperates with the first through hole. A carrier plate for supporting the FPC can be placed at the upper end of the die cavity.
[0005] The punch holder is fixedly provided with a guide post, which slides through the stripper plate and cooperates with the second through hole.
[0006] It also includes a material unloading tray, which can be moved between the stripper plate and the die.
[0007] The unloading tray has a loading groove for carrying the FPC.
[0008] The lower mold base has a discharge hole that communicates with the first through hole.
[0009] The suction nozzle can be provided in multiple ways.
[0010] The elastic element is a spring.
[0011] The beneficial effects of this utility model are:
[0012] This utility model provides an FPC stamping die. In use, the carrier plate supporting the FPC is placed on the die cavity. Then, the upper die base is driven to press down until the stripper plate abuts against the carrier plate. The upper die base is then driven to press down further, causing the punch to stamp the FPC. Subsequently, an external vacuum pump generates negative pressure in the vacuum tube, allowing the suction nozzle to pick up the FPC. Then, the upper die base is driven to move upward, thereby moving the FPC away from the lower die, thus completing the FPC stamping and separation operation. This die integrates the suction cup mechanism and the upper die mechanism, so that each time the production line is changed, only the die needs to be installed, without the need to install and adjust the position of the suction cup mechanism, saving time and effort and improving production efficiency.

[0024] like Figure 1 and 2As shown, this application embodiment provides an FPC stamping die, including an upper die base 1 and a lower die base 2 disposed below the upper die base 1. A punch fixing frame 3 is fixedly disposed at the lower end of the upper die base 1. A punch 4 and a guide post 5 are fixedly disposed on the punch fixing frame 3. A stripper plate 6 is disposed below the punch fixing frame 3. An elastic element 7 is disposed between the punch fixing frame 3 and the stripper plate 6. A vacuum tube 8 and a suction nozzle 9 connected to the vacuum tube 8 are embedded on the stripper plate 6. The suction nozzle 9 penetrates the bottom of the stripper plate 6. A die cavity 10 is fixedly disposed at the upper end of the lower die base 2. The die cavity 10 has a first through hole 11 and a second through hole 12. The punch 4 slides through the stripper plate 6 and is used in conjunction with the first through hole 11. The guide post 5 slides through the stripper plate 6 and is used in conjunction with the second through hole 12. A carrier plate 13 for supporting FPC 17 can be placed at the upper end of the die cavity 10.
[0025] The carrier plate 13 carrying FPC17 is placed on the die 10. Then, the upper die base 1 is driven down until the stripper plate 6 abuts against the carrier plate 13. The upper die base 1 is then driven down to make the punch 4 punch the FPC17. Then, the vacuum pipe 8 is generated by the external vacuum pump to create negative pressure, and the suction nozzle 9 can pick up the FPC17. Then, the upper die base 1 is driven up to move the FPC17 away from the lower die, thus completing the FPC17 stamping and separation operation. This mold integrates the suction cup mechanism and the upper die mechanism, so that each time the production line is changed, only the mold needs to be installed, and the position of the suction cup mechanism does not need to be installed and adjusted, which saves time and effort and improves production efficiency. The elastic element 7 is a spring.
[0026] like Figure 1 and 2 As shown, this embodiment also includes a blanking tray, which can be moved between the stripper plate 6 and the die 10. In use, the upper die base 1 is driven to move upward, thereby moving the FPC17 away from the lower die. Then, the blanking tray is moved between the stripper plate 6 and the die 10. Then, the vacuum pipe 8 is depressurized by an external vacuum pump, and the FPC17 can fall off the suction nozzle 9 and onto the blanking tray. Then, the blanking tray is moved away from the mold, and the FPC17 stamping and separating operation is completed.
[0027] like Figure 1 and 2 As shown, in this embodiment, the unloading tray is provided with a material loading groove 15 for carrying the FPC17; in use, the FPC17 falls into the material loading groove 15 of the unloading tray, and the material loading groove 15 can improve the unloading stability of the FPC17.
[0028] like Figure 1 and 2As shown, in this embodiment, the lower die base 2 has a discharge hole 16 that communicates with the first through hole 11. During use, the waste generated by stamping falls from the first through hole 11 into the discharge hole 16 and is then discharged from the die. The discharge hole 16 allows the waste generated during the stamping process to be discharged directly, avoiding the accumulation of waste in the die and reducing the cleaning and maintenance costs of the die.
[0029] In this embodiment, multiple suction nozzles 9 can be provided, which further enhances the adsorption effect and is suitable for FPC17 of different sizes and shapes, improving the versatility and flexibility of the mold.
[0030] Working principle: When using the FPC stamping die provided in this application, the carrier plate 13 carrying the FPC17 is placed on the die cavity 10. Then, the upper die base 1 is driven to press down until the stripper plate 6 abuts against the carrier plate 13. Then, the upper die base 1 is driven to press down so that the punch 4 stamps the FPC17. The waste material generated by stamping falls from the first through hole 11 into the discharge hole 16 and is then discharged from the die. Then, the vacuum pipe 8 is made to generate negative pressure by an external vacuum pump, and the suction nozzle 9 can pick up the FPC17. Then, the upper die base 1 is driven to move upward, thereby moving the FPC17 away from the lower die. Then, the blanking tray is moved between the stripper plate 6 and the die cavity 10. Then, the vacuum pipe 8 is depressurized by an external vacuum pump, and the FPC17 can be separated from the suction nozzle 9 and fall into the loading groove 15 of the blanking tray. Then, the blanking tray is moved away from the die, and the FPC17 stamping and separation operation is completed.
[0031] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
