AI Technical Summary
When the existing button battery stamping molds are stamped with aluminum tape, the formed products are susceptible to pressure snap into the inside of the upper mold, which makes the aluminum tape inconvenient to move and feed, reducing production efficiency and product accuracy.
A stamping die including a fixing frame, a cover plate, a pressing plate, an extrusion structure and a guide structure is designed. The push plate is moved by a spring, so that the aluminum sheet is separated from the upper mold, and moves in the guide structure through the guide rod, reducing friction, and achieving rapid mold release and moving guidance.
The rapid demolding function is realized, which facilitates the separation of the product from the mold, improves production efficiency and product accuracy, and reduces movement resistance through the guide structure, and improves the smoothness of the stamping process.

[0024] Specifically, in this embodiment, the fixing frame 1 is installed on the top of the die groove 8 by using bolts, and then the movable plate 5, the upper mold 10, and the pressing plate 4 are installed in the inside of the fixing frame 1 in sequence, and the cover plate 2 is fixed to the top of the fixing frame 1 by using the locking bolts 3, and the aluminum strip is placed between the fixing frame 1 and the die groove 8. The pressing plate 4 is pushed to move inside the fixing frame 1 by using a stamping device, so that the pressing plate 4 drives the upper mold 10 to move downward, and the upper mold 10 punches the aluminum strip. At the same time, the extrusion structure 9 facilitates the separation of the upper mold 10 from the aluminum strip, and the movement of the upper mold 10 is guided by the guide rod 6 sliding inside the guide structure 7.
[0025] In a further preferred embodiment of the present invention, Figure 1-4 As shown: the extrusion structure 9 includes a fixed seat 901, a spring 902, a push plate 903 and a moving rod 904.
