[0007] Furthermore, a first connecting portion is welded between two adjacent convex dies.

[0008] Furthermore, the number of the concave dies is the same as the number of the convex dies.

[0009] Furthermore, the number of the concave mold and the number of the convex mold are both four.

[0010] Furthermore, a second connecting portion is welded between the two adjacent concave dies.

[0011] Furthermore, the second connecting portion is welded to the connecting pieces of two adjacent concave dies.

[0012] The utility model has the following beneficial effects:

[0013] (1) The stacking ankle batch stamping die of the utility model has a simple structure and is easy to manufacture and maintain;

[0014] (2) The stacked ankle batch stamping die of the utility model is designed to stamp several products at one time instead of one product at a time, and the die has high efficiency in producing products and reduces the manufacturing cost of the products. Description of the drawings:

[0015] Figure 1 This is a schematic diagram of the batch stamping die for stacked ankles of the present invention. Specific implementation method:

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] The utility model is a batch stamping die for stacking ankles, comprising an upper die part and a lower die part. The upper die part comprises an upper die base 1 and an upper die pad 2 welded to the lower surface of the upper die base 1. A plurality of spaced-apart punches 3 are welded on the lower surface of the upper die pad 2, and a first connecting portion 5 is welded between two adjacent punches 3.

[0018] The lower die portion includes a lower die base 7, a lower die pad 6 welded to the upper surface of the lower die base 7, and a limit plate 9 located above the lower die pad 6 and spaced apart from the lower die pad 6. A number of spaced-apart dies 4 are welded to the upper surface of the lower die pad 6 at intervals, and the number of dies 4 is the same as the number of punches 3. A second connecting portion 8 is welded between two adjacent dies 4. The dies 4 include a connecting piece 40 that surrounds the die and is spaced apart. The lower end of the connecting piece 40 is welded to the lower die pad 6, and the upper end of the connecting piece 40 is welded to the limit plate 9. The second connecting portion 8 is welded to the connecting pieces 40 of the two adjacent dies 4.

[0019] The working principle of the batch stamping die for stacking ankles of the utility model is as follows: the upper die part and the lower die part of the die are clamped and placed on a 200T hydraulic machine. First, align the upper die part with the lower die part front, back, left, and right and align the positions of several pieces (four pieces are listed in this embodiment) of unloading plates with the positions of the ejector rod holes on the machine base, then fix the lower die part with a slight force with a pressing plate, then slowly lower the slide plate on the machine tool to contact the upper die part of the die, and fix it with a pressing plate. Slowly raise the slide plate and the upper die part on the machine tool so that the upper die part is completely separated from the lower die part, then slowly lower the slide plate on the machine tool to press the ankle into shape, then slowly raise the upper slider and the upper die part to separate from the lower die part, finally slowly raise the ejector rod of the lower die base of the machine tool to completely lift the unloading plate and the product without obstruction, then completely fix the lower die part on the lower die base of the machine tool, and finally complete the production of the ankle through repeated up and down movements of the machine tool.

[0020] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as the scope of protection of the present invention.
