When the distance between the top plate and the top of the stamping groove is adjusted to match the required stamping depth, the mounting block is released, the third spring rebounds and drives the mounting block to slide inward through the third slider. When the fixing rod moves inward with the mounting block to be inserted into the fixing hole at the current position, the adjusting block can be fixed at the current height, thereby completing the adjustment of the top plate height. This design enables the mold to eject stamping parts of different sheet metal processes from the stamping groove, and has a wider range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The embodiments of the present application solve the problems in the prior art by providing an automobile sheet metal stamping die.

[0029] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0030] The specific structure of this embodiment is as follows: Figures 1 to 7 As shown, an automobile sheet metal stamping die comprises a lower die base 1, an upper die base 2 is arranged above the lower die base 1, a guide column 3 is arranged between the upper die base 2 and the lower die base 1, a stamping block 4 is arranged at the bottom of the upper die base 2, and limiting components 5 are arranged on both sides of the stamping block 4. A stamping groove 6 is opened at the top center of the lower die base 1, and an ejection component 7 is arranged inside the stamping groove 6.

[0031] In some examples, the limiting assembly 5 includes a first slide groove 51, a first through hole 52, a first connecting rod 53 and a pressure plate 54. The first slide groove 51 is opened inside the upper mold base 2, the first through hole 52 passes through the bottom inner wall of the first slide groove 51, the first connecting rod 53 is movably connected to the first through hole 52 and extends to the inside of the first slide groove 51, and the pressure plate 54 is fixedly connected to the bottom of the first connecting rod 53.

[0032] In some examples, the limiting assembly 5 also includes a first slider 55 and a first spring 56. The first slider 55 is fixedly connected to the top of the first connecting rod 53 and is slidably connected to the first slide groove 51. The first spring 56 is fixedly installed inside the first slide groove 51 and its two ends are respectively fixedly connected to the top of the first slider 55 and the inner wall of the top of the first slide groove 51. During the process of the stamping block 4 stamping the sheet metal part, the pressure plate 54 will first contact the sheet metal part. As the stamping block 4 continues to move downward, the pressure plate 54 drives the first slider 55 to slide upward along the first slide groove 51 through the first connecting rod 53 and squeezes the first spring 56. At this time, the rebound force of the first spring 56 will limit the sheet metal part to the current position. After the stamping is completed, the stamping block 4 moves upward, the first spring 56 rebounds and drives the pressure plate 54 to reset through the first slider 55 and the first connecting rod 53, so as to limit the sheet metal part during the next stamping.

[0033] In some examples, the ejection assembly 7 includes a top plate 71, a bottom plate 72, a mounting seat 73, a second slide groove 74, a second through hole 75, a second connecting rod 76, a second slider 77 and a second spring 78. The top plate 71 and the bottom plate 72 are both slidably connected to the stamping groove 6. The mounting seat 73 is fixedly connected to the top of the bottom plate 72. The second slide groove 74 is opened inside the mounting seat 73. The second through hole 75 runs through the inner wall of the top of the second slide groove 74. The top of the second connecting rod 76 is fixedly connected to the bottom of the top plate 71 and movably connected to the second through hole 75 and extends to the inside of the second slide groove 74. The second slider 77 is fixedly connected to the bottom of the second connecting rod 76 and slidably connected to the second The slide groove 74, the second spring 78 is fixedly installed inside the second slide groove 74 and the two ends are respectively fixedly connected to the bottom of the second slider 77 and the inner wall of the bottom of the second slide groove 74. During the stamping process of the sheet metal, the stamping block 4 will drive the stamping part of the sheet metal to move downward along the stamping groove 6. At this time, the top plate 71 moves downward with the sheet metal and drives the second slider 77 to slide downward along the second slide groove 74 through the second connecting rod 76 and squeeze the second spring 78. After the stamping is completed, the stamping block 4 moves upward, the second spring 78 rebounds, and drives the top plate 71 to move upward through the second slider 77 and the second connecting rod 76, thereby lifting the sheet metal that has been stamped.

[0034] In some examples, the ejection assembly 7 also includes an adjustment slot 79, an adjustment block 710, a fixing hole 711, a mounting block 712 and a fixing rod 713. The adjustment slot 79 is opened on one side of the lower die base 1 and is connected to the stamping slot 6. The adjustment block 710 is fixedly connected to the base plate 72 and slidably connected to the adjustment slot 79. The fixing holes 711 are provided in several groups and are opened on both sides of the adjustment slot 79. The mounting block 712 is sleeved and slidably connected to the outer periphery of the adjustment rod. The fixing rod 713 is fixedly connected to the inner ends of the mounting block 712 and is adapted to the size of the fixing hole 711. The height of the adjustment block 710 can be adjusted along the adjustment slot 79 by moving the fixing rod 713 out of the fixing hole 711. The adjustment block 710 can be fixed at the current height by inserting the fixing rod 713 into the fixing hole 711.

[0035] In some examples, the ejection assembly 7 also includes a third slide groove 714, a third slider 715 and a third spring 716. The third slide groove 714 is opened at the top of the adjustment block 710. The third slider 715 is fixedly connected to the mounting block 712 and slidably connected to the third slide groove 714. The third spring 716 is fixedly installed inside the third slide groove 714 and its two ends are respectively fixedly connected to one side of the third slider 715 and the inner wall of one side of the third slide groove 714. Pulling the mounting block 712 outward can drive the third slider 715 to slide outward along the third slide groove 714 and squeeze the third spring 716. Release the mounting block 712, and the third spring 716 rebounds to drive the mounting block 712 to move inward through the third slider 715.

[0036] In a specific application scenario, first place the sheet metal part to be stamped on the top of the stamping slot 6, and then start the mold to drive the stamping block 4 to move downward. During this process, the pressing plate 54 will first contact the sheet metal part. As the stamping block 4 continues to move downward, the pressing plate 54 drives the first slider 55 to slide upward along the first slide slot 51 through the first connecting rod 53 and squeeze the first spring 56. At this time, the rebound force of the first spring 56 will limit the sheet metal part to the current position, and then the stamping block 4 can stamp the sheet metal part and make its stamping position move downward along the stamping slot 6. At this time, the top plate 71 moves downward with the sheet metal part and drives the second slider 77 to slide downward along the second slide slot 74 through the second connecting rod 76 and squeeze the second spring 78. After the stamping is completed, the stamping block 4 moves upward, the second spring 78 rebounds and drives the top plate 71 to move upward through the second slider 77 and the second connecting rod 76, thereby lifting the sheet metal part that has been stamped upward, and the staff can take it out at this time. A spring 56 rebounds and drives the pressing plate 54 to reset through the first slider 55 and the first connecting rod 53, so as to limit the sheet metal part during the next stamping. When the sheet metal part needs to be stamped out to different depths, the mounting block 712 is pulled outward to drive the third slider 715 to slide outward along the third sliding groove 714 and squeeze the third spring 716. When the fixing rod 713 moves outward with the mounting block 712 and moves out of the fixing hole 711, the adjusting block 710 is slid along the adjusting groove 79 to drive the bottom plate 7 2 slides synchronously along the punching groove 6, and when the distance between the top plate 71 and the top of the punching groove 6 is adjusted to be suitable and adapted to the required punching depth, the mounting block 712 is released, the third spring 716 rebounds and drives the mounting block 712 to slide inward through the third slider 715, and when the fixing rod 713 moves inward along with the mounting block 712 to be inserted into the fixing hole 711 at the current position, the adjusting block 710 can be fixed at the current height, thereby completing the adjustment of the height of the top plate 71, and at this time, the sheet metal part can be punched at a new depth.

[0037] By adopting the above technical solution: not only can the sheet metal parts be limited during the stamping process to prevent the displacement of the sheet metal parts from affecting the stamping effect, but the sheet metal parts can also be automatically ejected after the stamping is completed, making it more convenient for the staff to take the sheet metal parts and effectively improving work efficiency.

[0038] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the present invention.
