[0024] Please refer to Figures 1 to 5The utility model provides a technical scheme: a back door outer plate forming die structure, including the stamping station 1, the stamping station 1 is fixed with the lower pressure station 2, the stamping station 1 is placed with back door outer plate main part 24, the lower pressure station 2 lower side is slid with the mounting bracket 4, the mounting bracket 4 is fixed with the upper die 5, the stamping station 1 is set up with the stamping groove 6, the upper die 5 corresponds with the stamping groove 6, the stamping station 1 is rotatably connected with a plurality of pivot 8, the pivot 8 is fixed with the fixed frame 9, and the fixed frame 9 is equipped with the lower pressure structure, and the lower pressure structure corresponds with the mounting bracket 4, and the fixed frame 9 one side is slid with the positioning structure, and the stamping station 1 is equipped with the ejection structure, and the ejection structure corresponds with the positioning structure.

[0025] In this embodiment, the lower pressure station 2 is fixed with a hydraulic cylinder 3, the output end of the hydraulic cylinder 3 is fixedly connected with the mounting bracket 4, and a plurality of supporting columns 23 are fixed between the stamping station 1 and the lower pressure station 2.

[0026] Specifically, the hydraulic cylinder 3 is started, so that the hydraulic cylinder 3 drives the mounting bracket 4 to move downward, the mounting bracket 4 slides on the supporting column 23, and the upper die 5 approaches the stamping station 1, so that stamping can be carried out.

[0027] A plurality of motors 7 are fixed on the lower side of the stamping station 1, the output end of the motor 7 is fixedly connected with the pivot 8, and the lower pressure structure includes an elastic telescopic rod 10 slidably connected with the fixed frame 9.

[0028] Specifically, the motor 7 is started, so that the pivot 8 is driven to rotate by the motor 7, so that the fixed frame 9 is driven to rotate, so that the pivot 8 does not need to be manually rotated, and the feeding and collection of the back door outer plate main body 24 are facilitated.

[0029] The elastic telescopic rod 10 includes a first rod body 11 and a second rod body 12, the first rod body 11 is slidably connected with the second rod body 12, and a first spring 13 is fixed between the first rod body 11 and the second rod body 12.

[0030] Specifically, with the downward sliding of the mounting bracket 4, the mounting bracket 4 extrudes the elastic telescopic rod 10, the elastic telescopic rod 10 relatively slides downward, the pressing plate 14 is in contact with the back door outer plate main body 24, and if the mounting bracket 4 continues to slide downward, the first rod body 11 can slide relative to the second rod body 12, so that the first spring 13 is compressed, and the overall length of the elastic telescopic rod 10 is shortened, so that the downward pressing of the mounting bracket 4 is prevented.

[0031] The end of the elastic telescopic rod 10 is fixedly connected with the pressing plate 14, the pressing plate 14 is in contact with the back door outer plate main body 24, the second spring 15 is fixed between the pressing plate 14 and the fixed frame 9, and the elastic coefficient of the second spring 15 is less than that of the first spring 13.

[0032] Specifically, when the mounting bracket 4 slides downward, the mounting bracket 4 presses the elastic telescopic rod 10, and the elastic telescopic rod 10 slides downward, thereby driving the pressure plate 14 to slide downward. The second spring 15 is stretched, so that the pressure plate 14 comes into contact with the back door outer panel body 24, and the back door outer panel body 24 can be pressed down and fixed.

[0033] The fixed frame 9 has a sliding groove 16 inside, and the positioning structure includes a positioning rod 19. A sliding rod 17 is fixed on the positioning rod 19. The sliding rod 17 corresponds to the sliding groove 16, and a nut 18 is threaded onto the sliding rod 17.

[0034] Specifically, when the rotating shaft 8 rotates, the rotating shaft 8 drives the fixed frame 9 to rotate, which in turn drives the slide rod 17 to rotate. The slide rod 17 then drives the positioning rod 19 to rotate, so that the positioning rod 19 comes into contact with the main body 24 of the outer panel of the back door. This allows the outer panel 24 of the back door to be pushed, thus positioning the outer panel 24 of the back door and fixing it from the side.

[0035] The ejection structure includes multiple ejection blocks 21. Multiple grooves 20 are provided on the stamping table 1. The ejection blocks 21 are elastically fitted in the grooves 20. The positioning rod 19 is in contact with the ejection blocks 21. The ejection blocks 21 are slidably connected to the grooves 20. A third spring 22 is fixed between the ejection blocks 21 and the groove wall of the groove 20. The end of the ejection blocks 21 has an arc-shaped structure.

[0036] Specifically, when the positioning rod 19 presses against the main body 24 of the outer panel of the tailgate, the positioning rod 19 will press against the ejector block 21, so that the ejector block 21 enters the groove 20 and the third spring 22 is compressed. After the pressing is completed, the positioning rod 19 rotates away. At this time, the positioning rod 19 no longer presses against the ejector block 21, so the third spring 22 rebounds, causing the ejector block 21 to push the main body 24 of the outer panel of the tailgate upward.

[0037] Workflow: When stamping the outer panel body 24 of the rear door needs to be performed, the outer panel body 24 is placed on the stamping table 1, and then the motor 7 is started, causing the rotating shaft 8 to rotate, which in turn causes the fixing frame 9 to rotate, so that the pressure plate 14 rotates above the outer panel body 24. At this time, the sliding rod 17 rotates, which in turn drives the positioning rod 19 to rotate, so that the positioning rod 19 contacts the outer panel body 24, thereby pushing the outer panel body 24 and positioning it. At the same time, the positioning rod 19 will squeeze the ejector block 21, so that the ejector block 21 enters the groove 20, the third spring 22 is compressed, and then the hydraulic cylinder 3 is started, causing the hydraulic cylinder 3 to drive the installation... The frame 4 moves downward, and the mounting frame 4 slides on the support column 23. The upper mold 5 approaches the stamping table 1, and the mounting frame 4 presses the elastic telescopic rod 10. The elastic telescopic rod 10 slides downward relative to the other, so that the pressure plate 14 contacts the main body 24 of the back door outer panel. If the mounting frame 4 continues to slide downward, the first rod 11 can slide relative to the second rod 12, so that the first spring 13 is compressed, the overall length of the elastic telescopic rod 10 is shortened, and the elastic telescopic rod 10 slides downward relative to the other, thereby driving the pressure plate 14 to slide downward. The second spring 15 is stretched, so that the pressure plate 14 contacts the main body 24 of the back door outer panel, and the main body 24 of the back door outer panel can be pressed down and fixed, thereby stamping the main body 24 of the back door outer panel.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
