[0030] Example

[0031] like Figure 1 As shown, the utility model provides a stamping die with a limiting mechanism, including an upper die seat 100, a lower die seat 220 and a driving structure for driving the upper die seat 100 to approach or move away from the lower die seat 220, and also includes a limiting structure for limiting the relative distance between the upper die seat 100 and the lower die seat 220, the limiting structure includes a mounting structure and a plurality of limiting blocks 310; the mounting structure is arranged in the interval space between the upper die seat 100 and the lower die seat 220, and the plurality of limiting blocks 310 are detachably connected to the mounting structure.

[0032] As those skilled in the art should know, the driving structure is used to drive the upper mold base 100 to move closer to or away from the lower mold base 220. Specifically, the driving structure includes but is not limited to a driving motor, a cylinder, etc., which are conventional technical means that can achieve a change in the relative distance between the upper mold base 100 and the lower mold base 220, and will not be elaborated here.

[0033] In the present embodiment, the stamping die has an upper die seat 100 and a lower die seat 220 which are driven by a driving structure to move closer to or away from each other, and also includes a limiting structure, wherein the limiting structure is used to achieve height limitation in the stamping direction, wherein the limiting structure includes a mounting structure and a plurality of limiting blocks 310 detachably connected to the mounting structure, and by installing different numbers of limiting blocks 310 on the mounting structure, the relative distance between the upper die seat 100 and the lower die seat 220 is limited; through the design of the limiting structure, compared with the stamping die in the prior art, the height adjustment can be achieved in a targeted manner by installing different numbers of limiting blocks 310 on the mounting structure, thereby adapting to various processing design needs.

[0034] As a specific structural form of the upper mold base 100, the upper mold base 100 includes an upper mounting plate 110 and an upper mold 120 arranged on one side of the upper mounting plate 110, and the driving structure is arranged on the upper mounting plate 110 to drive the upper mold 120 to approach or move away from the lower mold 220 seat.

[0035] As a specific structural form of the lower mold 220 seat, the lower mold 220 seat includes a lower mounting plate 210 and a lower mold 220 for cooperating with the upper mold 120 , and the lower mold 220 is arranged on a side of the lower mounting plate 210 close to the upper mold seat 100 .

[0036] Through the structural design of the upper mold base 100 and the lower mold base 220, the upper mold 120 and the lower mold 220 are respectively arranged on the upper mounting plate 110 and the lower mounting plate 210. Specifically, the areas of the upper mold 120 and the lower mold 220 are respectively smaller than the lower mounting plate 210 of the upper mounting plate 110. On the one hand, it is convenient to install the upper mold 120 and the lower mold 220, and on the other hand, it is convenient to set other functional components on the upper mounting plate 110 and the lower mounting plate 210.

[0037] In some embodiments, the mounting structure includes a mounting rod 320, and the mounting rod 320 has a mounting portion 321 arranged along the axial direction, and the mounting portion 321 is used to detachably cooperate with multiple limit blocks 310; wherein, the two ends of the mounting rod 320 are respectively connected to the upper mounting plate 110 and the lower mounting plate 210.

[0038] The two ends of the mounting rod 320 are respectively arranged on the upper mounting plate 110 and the lower mounting plate 210 , so as to avoid the mounting rod 320 affecting the working space of the stamping.

[0039] like Figure 2 As shown, as a specific structural form of the mounting portion 321, the mounting portion 321 is a slot structure, and there are two mounting portions 321, and the connecting line of the two mounting portions 321 is colinear with the diameter of the mounting rod 320; and the limit block 310 has a plane side 310a and an arc side 310b, wherein the plane side 310a is provided with a first protrusion 311 that cooperates with the mounting portion 321.

[0040] Specifically, through the structural design of the slot body structure and the first protrusion 311, the installation of the limit block 310 on the mounting rod 320 can be realized, and in the specific installation process, the limit block 310 can be tilted relative to the mounting rod 320, so that the first protrusion 311 can be installed in the slot body structure.

[0041] Furthermore, as an implementation method for facilitating the installation of the limiting block 310 , the installation rod 320 further includes a small-diameter section, and the diameter of the small-diameter section is smaller than the distance between the two first protrusions 311 .

[0042] In some embodiments, the mounting structure further includes a driving head 330, and the driving head 330 is arranged on the upper mounting plate 110. One end of the mounting rod 320 is rotatably connected to the lower mounting plate 210, and the other end of the mounting rod 320 cooperates with the driving head 330. When the driving structure drives the upper mounting plate 110 to move, the driving head 330 is used to drive the mounting rod 320 to rotate so as to realize the rotation of the limit block 310 into or out of the interval space between the upper mold 120 and the lower mold 220.

[0043] Specifically, by rotatably connecting the mounting rod 320 and the lower mounting plate 210, the limit block 310 can be specifically moved into the processed space of the upper mold 120 and the lower mold 220, thereby achieving relative position limitation between the two.

[0044] like Figure 4 As shown, as a specific embodiment for driving the mounting rod 320 to rotate, the driving head 330 has an inner cavity nested with the mounting rod 320, and the side wall of the inner cavity is provided with a second protrusion 331 for cooperating with the mounting rod 320; the mating ends of the mounting rod 320 and the driving head 330 are provided with a slide groove structure cooperating with the second protrusion 331; when the driving head 330 moves in the vertical direction, the second protrusion 331 cooperates with the slide groove structure to drive the mounting rod 320 to rotate.

[0045] like Figure 3 As shown, specifically, the slide groove structure includes a first path segment 322a, a second path segment 322b and a third path segment 322c which are arranged in sequence; wherein, the first path segment 322a and the third path segment 322c are straight groove bodies, and the connecting line of the projections of the first path segment 322a and the third path segment 322c on the cross section of the mounting rod 320 is arranged colinearly with the diameter of the mounting rod 320, and the second path segment 322b is a semi-spiral groove structure, when the second protrusion 331 slides from one end of the semi-spiral groove structure to the other end, the driving head 330 drives the mounting rod 320 to rotate half a circle.

[0046] Among them, when the second protrusion 331 slides along one end of the semi-spiral groove structure to the other end, the driving head 330 drives the mounting rod 320 to rotate half a circle. Specifically, by setting the length of the second path segment 322b, it is ensured that during rotation, the limit block 310 can be rotated to a limited extent within the working space of the upper mold 120 and the lower mold 220, thereby achieving the limitation of the relative distance between the upper mold 120 and the lower mold 220.

[0047] Specifically, by setting the first path segment 322a and the second path segment 322b, the reserved distance before and after the rotation is ensured to ensure that the stamping operation can be effectively completed.

[0048] In some embodiments, a line connecting the projections of the first path segment 322 a and the third path segment 322 c on the cross section of the mounting rod 320 and a line connecting the two mounting portions 321 are arranged perpendicular to each other.

[0049] Specifically, by arranging the line connecting the projections of the first path segment 322a and the third path segment 322c on the cross section of the mounting rod 320 and the line connecting the two mounting portions 321 to be perpendicular to each other, on the one hand, the stability of the installation of the limit block 310 on the mounting rod 320 can be ensured, and on the other hand, the drive head 330 can be prevented from detaching.

[0050] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above are only specific implementation methods of the utility model and are not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
