Embodiment Construction
[0019] The present invention will be specifically described below through examples, which are only used to further illustrate the present invention, and should not be construed as limiting the scope of protection of the present invention. Technical engineers in this field can make some non-essential improvements and Adjustment.
[0020] like Figure 2-7 As shown in the specific embodiment of the present invention, the process is integrally stamped and formed under the stamping die, and the stamping die includes an upper mold 1 and a lower mold 2, and the mold clamping surfaces of the upper mold 1 and the lower mold 2 are mutually matched. There is a mold cavity 3 embedded with the shank blank a, and the inner wall of the mold cavity is provided with a rib forming mold for forming a rib b1 on the shank blank; the rib forming mold in this embodiment includes: : be arranged on the forming convex rib 311 on the clamping surface of the upper mold 1 and be arranged on the clamping ...

The invention discloses a high heel shoe hook heart reinforcing rib and sharp edge portion integrated moulding technology; a stamping die can realize integrated stamping moulding, and comprises an upper die and a lower die; a die cavity nested with a hook heart blank is arranged in a compound die surface formed by the upper die and the lower die; the inner wall of the die cavity is provided with a reinforcing rib forming die used for forming reinforcing ribs on the hook heart blank; a position, corresponding to the lower edge of the head of the hook heart blank, on the inner wall of the die cavity is provided with a protruding stamping inclined plane die; the height, relative to the stamping inclined plane die, of the die cavity is smaller than the thickness of the head of the hook heart blank; the outer end, relative to the stamping inclined plane die, of the die cavity is provided with a deformation zone used for hook heart blank head material forward extension formation in the stamping process. The advantages are that the hook heart reinforcing ribs and the sharp edge portion are integrated in moulding, thus reducing production cost.
Description
technical field [0001] The invention relates to the processing field of footwear accessories, in particular to an integral molding process of reinforcing ribs and sharp blades of shanks of high-heeled shoes. Background technique [0002] The high heel shank is an important supporting part of the high heel sole, see figure 1 As shown, the shank 1' is installed between the outsole 2' and the midsole 3' of the sole of the high-heeled shoes, and plays a role in keeping the radian and stability of the sole. [0003] The existing shank forming process steps are generally: (1) cutting the steel plate into strip-shaped shank blanks; (2) drilling the shank blanks to process connecting holes; (3) cutting the shank blanks into strips; The shank blank plate treated in step (2) is bent into an arc shape under heat treatment to form a shank semi-finished product; (4) place the shank semi-finished product on the stamping die to punch out the reinforcing rib; (5) will go through the steps ...
