[0032] like Figures 1 to 6As shown, the embodiment of the present utility model proposes a stable anti-rebound automobile hardware stamping die, which includes a fixing frame 1, the inner wall of the fixing frame 1 is symmetrically fixedly connected to the limit plate 2, the interior of each limit plate 2 is slidably connected to a T-shaped slider 3, the adjacent side of each T-shaped slider 3 is fixedly connected to an inclined vertical plate 4, the bottom of each inclined vertical plate 4 is symmetrically fixedly connected to an inclined insertion rod 5, the interior of the fixing frame 1 is symmetrically opened with a slot 6, the interior of the fixing frame 1 is symmetrically opened with a movable groove 7, and the interior of each movable groove 7 is slidable.

[0036] In this embodiment, the hydraulic cylinder 13 drives the connecting block 14 to move, and when the connecting block 14 moves, it drives the fixed plate 15 to move. When the fixed plate 15 moves, it drives the inclined vertical plate 4, the limiting rod 16 and the upper mold 29 to move. The limiting rod 16 and the sliding sleeve 17 are used in conjunction to limit the fixed plate 15, thereby improving the vertical movement stability of the fixed plate 15, and the upper mold 29 contacts the lower mold 28 for stamping operation.

[0037] Example 3

[0038] like Figures 1-6 As shown, the inner wall of the fixing frame 1 is symmetrically fixedly connected to the limit seat 18, the interior of each limit seat 18 is slidably connected to the limit slider 19, the top of each limit slider 19 is fixedly connected to a splint 20, the outside of each splint 20 is fixedly connected to a connecting rod 21, each connecting rod 21 passes through the fixing frame 1 and is fixedly connected to a fixed head 23, the outside of the fixing frame 1 is symmetrically fixedly connected to a fixing seat 22, each connecting rod 21 is slidably connected to the corresponding fixing seat 22, and a second spring 24 is fixedly connected between each fixing seat 22 and the corresponding fixing head 23.

[0039] In this embodiment, when the inclined vertical plate 4 moves downward, its inclined surface contacts the inclined surface of the splint 20, thereby squeezing the splint 20 to move. When the splint 20 moves, it drives the connecting rod 21 to slide inside the fixed seat 22. When the connecting rod 21 slides, it drives the fixed head 23 to move. When the fixed head 23 moves, it squeezes the second spring 24 to cause it to deform. At the same time, when the splint 20 moves, it drives the limit slider 19 to slide inside the limit seat 18.

[0040] Working principle: When in use, place the lower mold 28 above the mounting block 27, start the hydraulic cylinder 13, the hydraulic cylinder 13 drives the connecting block 14 to move, and when the connecting block 14 moves, it drives the fixed plate 15 to move, and when the fixed plate 15 moves, it drives the inclined vertical plate 4, the limiting rod 16 and the upper mold 29 to move, and when the inclined vertical plate 4 moves, it drives the T-shaped slider 3 to slide inside the limiting plate 2. The combination of the limiting plate 2 and the T-shaped slider 3 can limit the inclined vertical plate 4 to improve the movement stability, and the combination of the limiting rod 16 and the sliding sleeve 17 can limit the fixed plate 15 to improve the fixation. The vertical movement stability of the plate 15 is ensured by the fact that when the inclined vertical plate 4 moves downward, its inclined surface contacts the inclined surface of the clamping plate 20, thereby squeezing the clamping plate 20 to move. When the clamping plate 20 moves, it drives the connecting rod 21 to slide inside the fixing seat 22. When the connecting rod 21 slides, it drives the fixing head 23 to move. When the fixing head 23 moves, it squeezes the second spring 24 to deform it. At the same time, when the clamping plate 20 moves, it drives the limiting slider 19 to slide inside the limiting seat 18. The cooperation between the limiting seat 18 and the limiting slider 19 can limit the clamping plate 20 and improve the movement stability. The two clamping plates 20 can be used to limit the movement stability. The plates 20 slide relatively to clamp the lower die 28, thereby achieving the effect of synchronous automatic clamping during the stamping process and improving the stamping stability. When the inclined vertical plate 4 moves, it drives the inclined rod 5 to insert into the interior of the slot 6. The inclined rod 5 squeezes the inclined block 9 inside the slot 6. The inclined block 9 is squeezed and drives the limit block 8 to move inside the movable slot 7. The limit block 8 can limit the inclined block 9 to ensure the accuracy of the moving position. When the limit block 8 moves, it drives the slide bar 10 to slide and squeeze the first spring 11. The card slot 12 inside the inclined rod 5 and the inclined block 9 After being located on the same horizontal line, the inclined surface block 9 is affected by the reaction force of the first spring 11, rebounds and resets and is stuck in the inside of the card slot 12, so that the inclined surface insertion rod 5 can be connected to the fixed frame 1, thereby preventing rebound and facilitating pressure maintenance. The pull rod 26 is pulled, and the pull rod 26 drives the pull ring 25 to move. The pull ring 25 drives the slide bar 10 to slide, and the slide bar 10 drives the inclined surface block 9 to disengage from the inside of the card slot 12, and then it can be released. The inclined surface block 9 is affected by the first spring 11 and rebounds and resets to the inside of the slot 6. The splint 20 is affected by the second spring 24 and rebounds and resets to the origin, which is convenient for the next stamping operation.
