DETAILED DESCRIPTION

[0019] The utility model is further described in detail in combination with the drawings and specific implementation.

[0020] In this embodiment, refer to Figures 1-6 , a kind of stamping die of convenient discharge of specific implementation, including upper die 1 and lower mould 2, the upper die 1 upper end is connected with driving arm 15 and drives upper die 1 to do reciprocating motion, the upper die 1 is matched with lower mould 2 and is formed by stamping material.

[0021] Further, the lower die 2 is mounted on the base plate 16 by screws, and the first ejector rod 4 and the guide rod 5 are both provided with a limiting part 3. The first ejector rod 4 and the guide rod 5 penetrate the lower die 2, and the base plate 16 is provided with a hole corresponding to the size of the limiting part 3, so that the limiting part 3 can move up and down in the hole. A spring 10 is arranged in the hole, and the spring 10 abuts against the lower end of the limiting part 3, thereby providing upward supporting force for the first ejector rod 4 and the guide rod 5, and ensuring that the upper end of the limiting part 3 is tightly connected with the lower die 2.

[0022] Further, the second ejector rod 6 is preferably made of plastic or other materials with buffering performance to avoid scratching the workpiece, and one end of the second ejector rod 6 is rotatably mounted on the upper end of the first ejector rod 4. This rotatable design enables the second ejector rod 6 to flexibly adjust the angle. The upper end of the guide rod 5 is provided with a cross rod 7, and the lower end of the second ejector rod 6 is provided with a positioning groove 11 matched with the cross rod 7. The design of the positioning groove 11 not only improves the structural stability of the mold, but also effectively avoids unnecessary shaking. In addition, the cross rod 7 pushes the second ejector rod 6 to rotate around the upper end of the first ejector rod 4, thereby adjusting the inclination angle of the second ejector rod 6.

[0023] Further, in the stamping process, the upper die 1 presses the first ejector rod 4 and the guide rod 5 downward, and when the first ejector rod 4 and the guide rod 5 are pressed downward, the limiting part 3 moves downward and pushes the spring 10 to shrink downward. When the stamping is completed and the pressure disappears, the elastic force of the spring 10 resets the limiting part 3, and at this time, the first ejector rod 4 and the guide rod 5 are also reset.

[0024] Further, the first ejector rod 4 is shorter than the guide rod 5, and the first ejector rod 4 lifts the workpiece after stamping, and then the second ejector rod 6 continues to rise and push the second ejector rod 6 to incline, so that the workpiece slides out along the second ejector rod 6. This design ensures that the material after stamping can be discharged from the lower die 2 in time, preventing material accumulation and thus affecting subsequent stamping operations, effectively improving production efficiency. In addition, the telescopic design of the discharging assembly also facilitates flexible adjustment according to the thickness of different materials and stamping requirements, further enhancing the applicability and flexibility of the mold.

[0025] Further, the upper end of the first ejector rod 4 is designed horizontally to ensure that when the second ejector rod 6 is inclined, it forms a certain angle with the upper end of the first ejector rod 4. At the same time, the first ejector rod 4 is slightly higher than the lower die 2, so that the workpiece can be smoothly discharged from the lower die 2 under the guidance of the first ejector rod 4 during the sliding process, effectively preventing the workpiece from being stuck in the lower die 2. This design significantly improves the accuracy and efficiency of discharging. In each mold stamping operation, this design can ensure that the workpiece is quickly and accurately discharged from the lower die 2, laying a good foundation for the next stamping operation, thereby further optimizing the overall production efficiency and product quality.

[0026] Further, the lower die 2 is internally provided with a receiving groove 12 which is shaped to match the second ejector rod 6 and the cross rod 7, ensuring that the second ejector rod 6 and the cross rod 7 can smoothly retract into the receiving groove 12 when the upper die 1 is pressed downward. When the upper die 1 rises, the second ejector rod 6 and the cross rod 7 can automatically return to the initial state by the elastic force of the spring 10, thereby conveniently and smoothly discharging the punched and formed workpiece from the die. This ingenious design simplifies the discharging process of the die without affecting the stability of the punching, and the precise size of the receiving groove 12 ensures that the second ejector rod 6 and the cross rod 7 are not hindered during operation, ensuring smooth operation of the die. At the same time, the introduction of the spring 10 enhances the automation level of the die, reduces the dependence on manual operation, and further improves the automation level of the production line.

[0027] Further, the discharging assembly adopts a modular design, so that the discharging assembly can be disassembled and assembled individually, facilitating the maintenance and upgrading of the die. This design not only improves the flexibility of the die, but also enables quick adjustment of the discharging assembly when changing different specifications of workpieces to adapt to new production needs. The application of modular design greatly shortens the time of die adjustment, improves the response speed of the production line, and thus creates higher economic benefits for enterprises.

[0028] Further, the upper die 1 is provided with a fixed frame 8 on both sides, which plays a limiting role for the material belt, ensuring that the material belt moves with the upper die 1 and avoiding being stuck by the second ejector rod 6 during the feeding process. Threaded rods 9 are provided at both ends of the fixed frame 8, and a slide block 13 is installed on one side of the threaded rod 9. The width between the two slide blocks 13 can be adjusted by the nut installed on the threaded rod 9 to adapt to material belts of various widths. This design not only enhances the applicability of the die, but also greatly improves the smoothness of the punching operation. The operator can quickly adjust the distance between the slide blocks 13 by adjusting the nut, ensuring that the material belt can be stably clamped between the fixed frames 8 regardless of the width of the material belt.

[0029] In addition, the pressing plate 14 is fixed on the slide block 13 by screws, and the height of the pressing plate 14 can be adjusted by loosening the screws to adapt to material belts of different thicknesses. The adjustability of the height of the pressing plate 14 brings great flexibility to the die, enabling the same set of dies to handle material belts of multiple specifications without frequent die replacement, significantly improving production efficiency. This design not only improves the versatility of the die, but also greatly simplifies the operation process, further expanding its application range. With its flexibility and adaptability, the die not only has high flexibility and versatility, but also realizes efficient and precise punching operation, providing strong support for the production of enterprises.
