[0054] Working principle process:

[0055] 1. Starting stage: The lower mold 1 and the upper mold 2 are in a closed state. At this time, the lower mold body 101 of the lower mold 1 is tightly fitted with the upper mold body 201 of the upper mold 2, and the various components in the mold are in preset positions. The pressing plates A301, B, and C in the pressing assembly 3 are located at the top, not in contact with the material surface, waiting for the material to enter. The supporting plates A401 and B in the supporting assembly 4 are ready to support the material that is about to enter, ensuring that the material is placed stably. The material is introduced and the mold is opened. The material is introduced from the outside and is guided by the material guide plate 407 and the guide rulers A405, B, C, and D, and is placed stably on the supporting plates A401 and B. When the material is in place, the mold begins to open, and the upper mold body 201 of the upper mold 2 moves upward under the action of the driving mechanism, driving the pressing plates A301, B, and C of the pressing assembly 3 to rise synchronously. The inner guide sleeve B252 of the upper mold 2 separates from the inner guide post B456 of the lower mold 1. The cooperation between the guide post assembly 151 and the guide sleeve seat 260 ensures precise guidance during the mold opening and closing process. The core inserts A304 and B rise with the binder plate, ready to press the material.

[0056] 2. Stamping stage: After the mold is fully opened, the material is fully exposed. At this time, the external manipulator accurately places the material directly above the die A158 to E. The mold is closed, the upper mold 2 moves downward, and the pressing plates A301, B, and C of the pressing assembly 3 drop accordingly. The pressing core insert A304 contacts B and presses the material. The upper mold insert 210 cooperates with the lower mold insert 110, and the punches A255 to E contact the corresponding dies respectively, apply pressure, complete the stamping process, and form different shape features of the workpiece. The nitrogen spring 251 provides stable stamping pressure to ensure the uniformity of the stamping process and the quality of the stamped parts. The spring locating pins A309 and B assist in the positioning and resetting of the pressing assembly 3 to ensure the accuracy of the positions of the pressing plates A301, B, and C.

[0057] 3. After stamping is complete, the die opens again, and the press assembly 3 rises. The material and stamped part, along with the support plates A401 and B, rest in the lower die 1. Stripper screws A153 and B assist in the removal of material or scrap, ensuring smooth removal of the stamped part from the die. Support plates A401 and B of the support assembly 4, activated by support plate springs 156, return to their original position, ready to support the next material. Guide rails C451 and D guide the material smoothly along the predetermined path, ensuring accurate guidance and preventing deviation.

[0058] 4. At the end of the cycle, the mold closes again and the material or stamped part is removed by a robot or automated device, preparing the mold for the next stamping cycle. Lifting bars A102 and B facilitate lifting and handling of the mold, allowing for quick mold changes when needed, improving production efficiency and safety.
