DETAILED DESCRIPTION

[0022] The present invention will now be described clearly and completely with reference to the embodiments.

[0023] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0024] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] See appendix Figures 1-5 The image shows a combined automobile tailgate stamping die, including an upper die 1 and a punch 3. The upper die 1 includes a body 4, and a die cavity 5 is provided on the side of the body 4 near the punch 3. The die cavity 5 is used to accommodate the deformation generated during sheet metal stamping.

[0026] The punch 3 includes a punch top 6 and a fitting part 7, wherein the punch top 6 is used in conjunction with the die cavity 5. During sheet metal stamping, the outer or inner panel of the car tailgate is obtained by interlocking and pressing the punch top 6 and the die cavity 5.

[0027] The outer ring 2 is fitted around the punch 3. The outer ring 2 can be shared on the punch 3 of the outer plate and the inner plate. The height of the fitting part 7 of the punch 3 is equal to the depth of the outer ring 2. The outer contour of the outer ring 2 is the same as the structure of the body 4. The outer ring 2 includes a top plate 8 and a bottom plate 9 arranged in parallel. A connecting plate 17 is provided between the top plate 8 and the bottom plate 9. The forming path of the connecting plate 17 is the same as the outer contour of the punch 3. The inner sidewalls of the top plate 8, the bottom plate 9 and the connecting plate 17 are coplanar. When in use, the outer ring 2 only needs to be fitted onto the punch 3 of the outer plate or the inner plate. In this way, when making the stamping mold of the outer plate and the inner plate, only one outer ring 2 of the punch 3 needs to be made. One outer ring 2 realizes the sharing between two punches 3, which improves the versatility between the molds of the outer plate and the inner plate, saves the material of one outer ring 2, and reduces the cost of mold making.

[0028] Furthermore, a number of first reinforcing ribs 11 are provided between the top plate 8 and the bottom plate 9. By providing the first reinforcing ribs 11, the structural strength of the entire outer pressure ring 2 is increased, preventing deformation during stamping.

[0029] Furthermore, multiple guide blocks 15 are arranged in a rectangular shape around the body 4. The cross-section of the guide block 15 is rectangular. The outer ring 2 is provided with a first limiting block 13 and a second limiting block 14 on the two adjacent side walls of the guide block 15. During stamping, the cooperation between the guide block 15 and the first limiting block 13 and the second limiting block 14 improves the accuracy of the engagement between the upper die 1 and the punch 3.

[0030] Furthermore, in order to facilitate the fitting of the outer ring 2, multiple lifting lugs 12 are arranged in a rectangular shape on the outer wall of the outer ring 2;

[0031] Furthermore, multiple guide portions 10 are vertically provided on the inner wall of the outer ring 2. The guide portions 10 reduce the gap between the punch 3 and the inside of the outer ring 2, thereby improving the stability of the punch 3 during stamping.

[0032] Furthermore, the body 4 is provided with multiple second reinforcing ribs 16 interlaced on the back of the mold cavity 5. The second reinforcing ribs 16 improve the overall structural strength of the upper mold 1 and also realize the lightweight design of the upper mold 1.

[0033] The beneficial effect of this utility model is that, through the detachable assembly of the punch 3 and the outer pressure ring 2, the punch 3 of the two molds can share the same outer pressure ring 2 when stamping the outer plate and the inner plate. This means that only one outer pressure ring 2 needs to be processed when processing the stamping molds of the outer plate and the inner plate, which not only improves the versatility of the molds of the outer plate and the inner plate, but also saves the material of one outer pressure ring 2 and reduces the cost of mold production.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape and principle of the present utility model should be included within the scope of protection of the present utility model.
