[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-3 This utility model provides an embodiment of a metal sheet stamping die, including a lower die 1, a groove 7 fixedly installed above the lower die 1, the lower die 1 and the groove 7 being an integral mechanism, a forming groove 701 being provided inside the groove 7, an inner cavity 101 being provided inside the lower die 1, an ejector assembly being provided inside the inner cavity 101 of the lower die 1, the ejector assembly including a horizontal plate 8, an ejector pin 9, a compression spring 10 and a lifting pin 11, guide cylinders 12 being symmetrically fixedly installed on both sides above the groove 7, an upper die 2 being provided above the lower die 1, and a stamping punch being fixedly installed in the middle below the upper die 2. The platform 6, the stamping boss 6 and the forming groove 701 are positioned correspondingly. Guide pillars 13 are symmetrically fixedly installed on both sides below the upper mold 2. The two guide pillars 13 are respectively positioned corresponding to the two guide cylinders 12. The top pillar 9 is fixedly installed in the middle above the horizontal plate 8. The upper end of the top pillar 9 slides into the interior of the forming groove 701. Multiple compression springs 10 are provided and fixedly installed below the horizontal plate 8. Two lifting pillars 11 are provided. The two lifting pillars 11 are fixedly installed on both sides above the horizontal plate 8. The upper end of the lifting pillar 11 slides into the interior of the guide cylinder 12.

[0023] By setting an ejector assembly, during the stamping of the metal sheet, the metal sheet is placed in the forming groove 701, driving the upper die 2 to move downward, causing the stamping boss 6 and guide post 13 to move downward. During the stamping process of the stamping boss 6 on the metal sheet, the guide post 13 will move downward into the guide cylinder 12. Through the cooperation of the guide post 13 and the guide cylinder 12, a guiding structure is formed, improving the accuracy of the closure of the upper die 2 and the lower die 1. As the guide post 13 continues to move downward in the guide cylinder 12, it will press the lifting post 11 to move downward, thereby driving the horizontal plate 8 to move downward. The compression spring 10 is compressed, and the ejector post 9 moves downward without hindering the stamping of the metal sheet. After the metal sheet is stamped, the upper die 2 moves upward, and the guide post 13 disengages from the guide cylinder 12. Through the elastic tension of the compression spring 10, the ejector post 9 moves upward elastically, thereby pushing the formed metal sheet, which facilitates the unloading of the metal sheet and increases its practicality.

[0024] Furthermore, a mounting base plate 3 is installed below the lower mold 1, and the lower mold 1 and the mounting base plate 3 are fixedly connected by screws. Mounting top brackets 4 are symmetrically fixedly installed on both sides above the upper mold 2, and multiple bolt holes are provided inside the mounting top brackets 4.

[0025] The lower mold 1 is fixedly connected to the mounting base plate 3 with screws, and the upper mold 2 is fixed to the mounting top frame 4 with bolts, which makes the installation and disassembly of the mold more convenient and increases its practicality.

[0026] Furthermore, a feeding assembly 5 is provided above the mounting base plate 3 along one side of the lower mold 1. The feeding assembly 5 includes a fixed box 501, a transmission column 502, a rotating plate 503, and an electromagnetic chuck 504. The fixed box 501 is fixedly connected to the mounting base plate 3. The transmission column 502 is rotatably mounted above the fixed box 501. The rotating plate 503 is fixedly mounted above the transmission column 502. The electromagnetic chuck 504 is fixedly mounted at one end below the rotating plate 503. A motor 14 is fixedly mounted inside the fixed box 501. The output end of the motor 14 is fixedly connected to the transmission column 502.

[0027] The unloading assembly 5 drives the transmission column 502 and the rotating plate 503 via the motor 14 to achieve automated unloading, reduce manual operation, and improve production efficiency. The electromagnetic chuck 504 can adsorb the formed metal sheets, making it easy to transfer them to the designated position and avoiding errors when picking up parts manually. The design of the rotating plate 503 allows the electromagnetic chuck 504 to rotate. The adsorption method of the electromagnetic chuck 504 avoids the scratches or deformation that may be caused to the surface of the metal sheets by traditional mechanical clamping, reducing product loss. This automated unloading design improves production efficiency.

[0028] Working principle: During use, when stamping the metal sheet, the metal sheet is placed in the forming groove 701 of the lower die 1, driving the upper die 2 to move downward, causing the stamping boss 6 and guide post 13 to move downward. During the stamping process of the stamping boss 6, the guide post 13 moves downward into the guide cylinder 12. The cooperation between the guide post 13 and the guide cylinder 12 forms a guiding structure, ensuring the accuracy of the closure of the upper die 2 and the lower die 1. At the same time, the continued downward movement of the guide post 13 will press the lifting column 11 to move downward, thereby driving the horizontal plate 8 to move downward. The compression spring 10 is compressed, and the top post 9 moves downward accordingly. The upper die 2 moves downward to avoid hindering the stamping and forming of the metal sheet. After the metal sheet is stamped and formed, the upper die 2 moves upward, and the guide post 13 gradually separates from the guide cylinder 12. At this time, the elastic tension of the compression spring 10 causes the top post 9 to move upward elastically, pushing the formed metal sheet out of the forming groove 701, which facilitates the unloading of the metal sheet. Then, the unloading assembly 5 drives the transmission column 502 and the rotating plate 503 through the motor 14, so that the electromagnetic chuck 504 rotates onto the metal sheet and is energized, adsorbing the formed metal sheet and then transferring it to the designated position, realizing automated unloading and increasing practicality.
