[0022] Workflow: In use, first install each component into the predetermined position of the equipment. Then, place the product material into the inner cavity of the main mold core 4. The die head body 93 moves downward under the drive of the equipment until it extends into the main mold core 4, whereby the product material inside the main mold core 4 can be stamped. During this process, the auxiliary mold core 6 moves to the bottom bend of the main mold core 4 under the drive of the ejector rod 8. In addition, during the stamping operation, the generated debris falls into the chip discharge channel 73 in the chip discharge cylinder 71 through the chip discharge hole 72 in the inner cavity of the auxiliary mold core 6, and then is discharged from the chip guide port 74 on the outer wall of the chip discharge cylinder 71. After the stamping operation is completed, the die head body 93 retracts and moves away from the main mold core 4. The ejector rod 8 works again, driving the auxiliary mold core 6 upward through the chip discharge cylinder 71 to eject the stamped product. After the operator removes it, the ejector rod 8 retracts and drives the auxiliary mold core 6 back to the bottom working position of the main mold core 4 through the chip discharge cylinder 71, and then the next cycle begins.

[0023] It should be noted that the working principle of the stamping equipment used in stamping dies is well known to those skilled in the art, and therefore will not be elaborated upon.

[0024] In summary, this utility model adjusts the integrated mold core structure into a split structure where the main mold core and auxiliary mold core work together. During stamping operations, the upper end of the auxiliary mold core is located at the curved part of the bottom end of the main mold core. The two can be combined to form a complete product mold core structure. Therefore, when the mold core is worn and needs to be replaced or maintained, the user only needs to replace and maintain the corresponding mold core component, thereby reducing maintenance costs. At the same time, the chip discharge cylinder at the bottom end of the auxiliary mold core can discharge the debris generated during operation through the chip discharge channel and chip guide port, which helps to improve product quality.
