[0029] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0030] like Figure 1 to Figure 5 As shown, a metal stamping die in one embodiment of the utility model includes a main body component 1 and an auxiliary component 2.

[0031] like Figure 1 to Figure 5 As shown, the main body component 1 includes a top plate 11 and a bottom plate 12, the top plate 11 is arranged above the bottom plate 12, an upper mold 13 is installed at the bottom of the top plate 11, and a lower mold 14 is installed above the bottom plate 12, and the positions of the upper mold 13 and the lower mold 14 correspond to each other; when stamping automobile parts, the upper mold 13 and the lower mold 14 interact with each other through the drive of the power device, so that the stamping of automobile parts can be completed.

[0032] like Figure 2 and Figure 4 As shown, a plurality of support rods 15 are installed between the top plate 11 and the bottom plate 12.

[0033] A plurality of first threaded holes 19 are provided on the top plate 11, and the lower ends of the plurality of support rods 15 are respectively threadedly connected in the plurality of first threaded holes 19. There are four support rods 15, and they are arranged at the four corners of the top plate 11 and the bottom plate 12. The four support rods 15 limit the position of the top plate 11 moving up and down, so that the top plate 11 will not tilt when moving. At the same time, the lower ends of the support rods 15 are threadedly connected to the bottom plate 12 through the first threaded holes 19, so that the support rods 15 can be easily disassembled and assembled.

[0034] like Figure 1 to Figure 5 As shown, a driving device 17 is installed at the upper end of the support rod 15, and a mounting head 18 is integrally formed at the upper end of the driving device 17. When stamping automobile parts, the upper mold 13 needs to be moved so that the upper mold 13 and the lower mold 14 cooperate to stamp the parts. Therefore, in order to realize the movement of the upper mold 13, a driving device 17 is provided so that the upper mold 13 can be driven to move by the driving device 17.

[0035] like Figure 2 to Figure 4 As shown, a plurality of mounting holes 16 are provided on the top plate 11, and the mounting heads 18 are mounted in the mounting holes 16. Since the driving device 17 can move up and down on the support rod 15, the movement of the driving device 17 can drive the top plate 11 to move up and down, thereby driving the top plate 11 to move up and down through the action of the driving device 17.

[0036] like Figure 1 to Figure 6 As shown, the accessory component 2 includes a movable rod 21, and the movable rod 21 is provided with a plurality of movable holes 22 at the groove of the lower mold 14, and a plurality of slots 23 are provided on the bottom plate 12. The plurality of movable holes 22 correspond to the positions of the plurality of slots 23. The plurality of movable rods 21 are respectively slidably connected in the plurality of movable holes 22, and a first compression spring 24 is installed in the slot 23, and the upper end of the first compression spring 24 abuts against the bottom of the movable rod 21. Since the movable rod 21 is slidably connected in the movable hole 22, the movable rod 21 can slide up and down in the movable hole 22. At the same time, since the bottom of the movable rod 21 abuts against the upper end of the first compression spring 24, the movable rod 21 can slide downward to compress the first compression spring 24, so that the first compression spring 24 has an upward elastic force on the movable rod 21.

[0037] Specifically, Figure 6 As shown, when the upper mold 13 and the lower mold 14 cooperate to impact the automobile parts, the impacted parts will contact the movable rod 21, and the parts will push the movable rod 21 to move downward, and the movable rod 21 will compress the first compression spring 24. After the impact is completed, the upper mold 13 and the lower mold 14 are separated, and the first compression spring 24 can push the parts to move upward, so that

[0038] The stamped parts are separated from the lower die 14, making it easy to take the stamped parts. At the same time, multiple movable rods 21 are provided, so that the stamped parts can be pushed by multiple movable rods 21, ensuring that the stamped parts are separated from the lower die 14 by the push of the movable rods 21, so that the stamped parts can be easily taken.

[0039] like Figure 1 to Figure 4 As shown, a plurality of limiting rods 25 are fixedly connected to the upper mold 13, and a plurality of limiting holes 26 corresponding to the limiting rods 25 are opened on the top plate 11. There are four limiting rods 25, and the four limiting rods 25 are arranged at the four corners of the upper mold 13.

[0040] like Figure 1 to Figure 4 As shown, the upper end of the limiting rod 25 passes through the limiting hole 26 and is placed above the top plate 11, and the upper end of the limiting rod 25 is threadedly connected to the limiting nut 28. The top plate 11 can move relative to the limiting rod 25 under the action of the limiting hole 26, and under the action of the four limiting rods 25, the top plate 11 and the limiting rod 25 will not tilt when they move relative to each other.

[0041] like Figure 1 and Figure 5 As shown, the limiting rod 25 is sleeved with a second compression spring 27, and the second compression spring 27 is placed between the top plate 11 and the upper mold 13. When the top plate 11 moves downward, the second compression spring 27 is compressed, and the second compression spring 27 pushes the upper mold 13 to move downward, so that the upper mold 13 punches the parts on the lower mold 14, and the second compression spring 27 buffers the force between the upper mold 13 and the lower mold 14, avoiding damage to the parts caused by direct impact, thereby improving the punching effect on the parts.

[0042] like Figure 3 and Figure 4 As shown, a plurality of through holes 210 are formed on the lower mold 14 , and a plurality of second threaded holes 211 corresponding to the through holes 210 are formed on the bottom plate 12 .

[0043] like Figure 3 and Figure 4 As shown, a fixing screw 29 is installed on the lower mold 14 and the bottom plate 12, and the lower end of the fixing screw 29 passes through the through hole 210 and is threadedly connected to the second threaded hole 211. The fixing screw 29 can fix the lower mold 14 on the bottom plate 12, and the fixing screw 29 makes the lower mold 14 easy to disassemble and assemble, so that the lower mold 14 is easy to replace when in use.

[0044] When in use, the automobile parts to be stamped are placed on the lower die 14, and the top plate 11 can be driven to move downward under the action of the driving device 17, and the second stamping

[0045] The compression spring 27 is compressed, so that the second compression spring 27 pushes the upper mold 13 to move downward. When the upper mold 13 contacts the parts, the parts begin to be stamped. During stamping, the second compression spring 27 will continue to be compressed, thereby buffering the impact force between the upper mold 13 and the lower mold 14, thereby improving the stamping effect on the parts. At the same time, when the parts contact the movable rod 21 during stamping, the movable rod 21 will be pushed to move downward, so that the movable rod 21 compresses the first compression spring 24. After the stamping is completed, the driving device 17 drives the top plate 11 to move upward, thereby driving the upper mold 13 to move upward. When the upper mold 13 is separated from the lower mold 14, the first compression spring 24 will push the movable rod 21 to move upward, and the movable rod 21 will push the stamped parts to separate from the lower mold 14, making it convenient to take the stamped parts.
