Detachable shoe tree and preparation method thereof

Abstract

The invention relates to the technical field of shoemaking, in particular to a detachable shoe tree and a preparation method thereof. The shoe tree comprises a clamping piece, a shoe tree core and a shoe tree shell wrapping the shoe tree core, the shoe tree core comprises a half sole part, a heel part, an upper transition piece and a connecting assembly, the lower end of the half sole part and the lower end of the heel part are connected through the connecting assembly, the upper end of the half sole part and the upper end of the heel part form a V-shaped groove, and the clamping piece is inserted into the V-shaped groove and is locked with the half sole part; the upper transition piece is detachably mounted on the half sole part or detachably mounted on the half sole part and the heel part; and at least one separation piece is arranged at the joint of the half sole part and the heel part, extends out of the joint and divides the shoe tree shell into two parts. The method for preparing the shoe tree comprises five steps of shoe tree core preparation, assembly, injection molding, cooling shaping and finish machining. The shoe shape of the shoe tree is changed through the upper transition piece, and the size of the shoe tree is changed through the shoe tree shell, so that the requirements of different shoe shapes and shoe sizes are met, meanwhile, the cost is saved, and the utilization rate of the shoe tree is increased.

Description

technical field [0001] The invention relates to the technical field of shoemaking, in particular to a detachable shoe last and a preparation method thereof. Background technique [0002] Shoe last is the matrix of shoes and the forming mold of shoes. The shoe last not only determines the shape and style of the shoe, but also determines whether the shoe fits and protects the foot. At present, one shoe last is only suitable for one shoe size and one shoe shape, but the trend of people’s aesthetic changes is very fast, and the shoe last is updated very quickly, which causes a large number of shoe lasts to be updated, and the cost increases; and most Shoe lasts are all made of plastic injection molding, and the process of recycling is complicated and costly. In addition, during the injection molding process of shoe lasts, the whole shoe last will be divided into forefoot and heel by cutting. If the cutting surface is uneven and the size changes, and only shoes with a fixed sty...

Problems solved by technology

At present, one shoe last is only suitable for one shoe size and one shoe shape, but the trend of people’s aesthetic changes is very fast, and the shoe last is updated very quickly, which causes a large number of shoe lasts to be updated, and the cost increases; and most Shoe lasts are all made of plastic injection molding, and the process of recycling is complicated and costly. In addition, during the injection molding process of shoe lasts, the whole shoe last will be divided into forefoot and heel by cutting. The cutting surface is uneven and the size changes, and only shoes with a fixed style and size can be made. Once the shoe last is cut, it cannot be reprocessed to change the size and style.
