[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping molds). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts. In the automotive manufacturing industry, the advent of dies has greatly accelerated the production of automotive parts, ensuring rapid assembly efficiency across the entire automotive production line. Automotive parts dies are specialized tools made according to the specific shape and dimensions of automotive parts, which are then stamped to produce the automotive parts.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides an embodiment of a high-strength steel plate forming mold for automotive stamping, comprising an upper mold fixing assembly 1 and a lower mold fixing assembly 2. The upper mold fixing assembly 1 includes an upper mold base 11, air pipes 12, and an upper template 13. The lower mold fixing assembly 2 includes a lower mold base 21 and a lower template 23. The upper mold base 11 is mounted on the bottom of the upper mold fixing assembly 1. Two sets of air pipes 12 are mounted on one side of the upper mold base 11. The upper template 13 is connected to the bottom of the upper mold base 11. The upper die holder 11 is provided with a lower die fixing assembly 2, and a lower die base 21 is installed on the upper surface of the lower die fixing assembly 2. A lower template 23 is installed on the top of the lower die base 21. A stamping assembly 3 is provided inside the upper die base 11. The stamping assembly 3 includes a stamping head 31. The stamping head 31 is fixedly installed at the center of the upper die base 11. The lower end of the stamping head 31 is fixedly connected to the upper template 13. The upper template 13 is connected to the upper die base 11 through the stamping head 31. An ejection assembly 4 is provided inside the lower die fixing assembly 2.

[0023] This device, through the setting of the ejection component 4 and the material handling component 5, solves the problem that the outer wall of the part is relatively close to the inner wall of the lower mold, making it difficult to remove the part, and the mold removal process is cumbersome, which can easily affect production efficiency.

[0024] Furthermore, the ejection assembly 4 includes cylinders 41 and dampers 42. Four sets of cylinders 41 are fixedly installed at the four corners of the lower mold base 21, and four sets of dampers 42 are symmetrically installed on the inner side of the lower mold base 21. Figure 4 As shown, this structure is used to press the upper template 13 and the lower template 23 together by starting the stamping head 31. When the upper template 13 descends, the damper 42 limits the upper template 13 to prevent the upper template 13 from directly contacting the lower template 23. After the stamping is completed, the cylinder 41 is started. Under the action of the cylinder 41, the material is pushed to detach from the surface of the lower template 23.

[0025] Furthermore, a material handling assembly 5 is provided inside the lower die base 21. The material handling assembly 5 includes a guide block 51 and a servo motor 52. Two sets of guide blocks 51 are fixedly installed inside the lower die base 21. A fixing block is provided on the surface of the lower die plate 23 to create a groove after the material is stamped. Two sets of servo motors 52 are symmetrically installed at the bottom center of the lower die base 21. An L-shaped connecting plate is fixedly connected to the output end of the servo motor 52. Figure 4 As shown, this structure is used to start the servo motor 52 after the material is separated from the surface of the lower template 23. The servo motor 52 drives the L-shaped connecting plate to rotate. When the L-shaped connecting plate rotates, its end is stuck in the concave surface of the material, pushing the material to move. The material moves under the guidance of the guide block 51.

[0026] Furthermore, a guide assembly 6 is provided on the rear side of the lower mold base 21. The guide assembly 6 includes a guide plate 61 and a movable plate 62. The movable plate 62 is rotatably connected to the rear end of the lower mold base 21. The movable plate 62 is L-shaped, and two sets of guide plates 61 are connected to the front end of the movable plate 62. The other end of the guide plate 61 is in contact with the lower mold plate 23. Figure 4 As shown, this structure is used to push the material to the surface of the guide plate 61 by the servo motor 52, and is rotatably connected to the lower mold base 21 by the movable plate 62. Pressing the outer end of the movable plate 62 causes the material to slide down along the guide plate 61 and the movable plate 62.

[0027] Furthermore, eight sets of positioning grooves 7 are symmetrically provided on the front and rear sides of the bottom of the lower mold base 21. The positioning grooves 7 are U-shaped, and lifting rings 22 are installed at the edge of the lower mold base 21. Figure 4 As shown, this structure is used to facilitate the fixing of the lower mold base 21 to the surface of the lower mold fixing assembly 2 by bolts through the positioning groove 7, and to facilitate the movement and transfer of the lower mold base 21 through the lifting ring 22.

[0028] Furthermore, the servo motor 52 is located within the hole of the lower template 23, and the end of the L-shaped connecting plate is made of rubber. Figure 4As shown, this structure is used to drive the L-shaped connecting plate to rotate via the servo motor 52, so that the end of the L-shaped connecting plate contacts the groove at the material. The end is made of rubber to avoid wear on the material when pushing it to move.

[0029] Furthermore, the upper template 13 is provided with an embedding portion for contacting the output ends of the cylinder 41 and the damper 42. For example... Figure 3 As shown, this structure is used to activate the cylinder 41, so that the output end of the cylinder 41 contacts the material, pushes the material upward, and causes the material to detach from the surface of the lower template 23. When the upper template 13 descends, the damper 42 passes through the embedded part and contacts the upper mold base 11 to limit its movement.

[0030] Working principle: When using, such as Figure 1 and Figure 3 As shown, the material is conveyed to the surface of the lower template 23 and positioned. Then, the punch head 31 is activated, pushing the upper template 13 to move towards the lower template 23, thus punching the material on the surface of the lower template 23. Figure 4 As shown, when the upper template 13 descends, the damper 42 passes through the embedded part and contacts the upper mold base 11 to limit its movement. After stamping, the cylinder 41 is activated to contact the material, pushing the material upward and causing it to detach from the surface of the lower template 23. After the material detaches from the surface of the lower template 23, the servo motor 52 is activated, driving the L-shaped connecting plate to rotate. When the L-shaped connecting plate rotates, its end contacts the concave surface of the material, thereby pushing the material to move. The material moves under the guidance of the guide block 51 and is pushed to the surface of the guide plate 61 by the servo motor 52. The material is rotatably connected to the lower mold base 21 by the movable plate 62. Pressing the outer end of the movable plate 62 causes the material to slide down the guide plate 61 along the movable plate 62. The above is the complete working principle of this utility model.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
