Shoe last two-section development method

Abstract

The invention discloses a shoe last two-section development method. The method comprises the steps that a shoe last is divided into the rear section and the head type which are connected to the left widest part and the right widest part of the base plate of the shoe last, the rear section comprises seven rear section big series of high sandals, low sandals, frye boots with zippers, frye boots without zippers, pump shoes with ankle straps, normal pump shoes and high instep close shoes according to the shoe types, the head type comprises three head type big series of a square head, a round head and a pointed head, the seven rear section big series and three head type big series are mutually matched in a one-to-one mode, and a complete shoe last is formed. The seven rear section big series comprise one or more rear section small series according to heel heights, the three head type big series comprise three head type medium series according to big, medium and small, the rear section small series and the head type medium series are mutually matched in a one-to-one mode, and the complete shoe last is formed. According to the shoe last two-section development method, the cost is better reduced, new shoe lasts are combined through convenient and flexible selection and matching, overall design and development of the shoe last are more convenient to achieve, and the development efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of shoe development, in particular to a two-stage development method of a shoe last. Background technique [0002] The existing shoe last development is generally to choose a relatively close last according to the shoe shape, and then modify it, slowly repairing and adjusting from the head to the tail, which is time-consuming and laborious. There is no concept of dichotomy, and the scope of modification is too large , every time a new last is developed, it must be from the head to the tail, and there is no concept of unified sharing of categories. Specifically, the development and production of the existing shoe last is usually a whole, that is to say, the back section of the shoe last and the head shape are integral and inseparable. Then, when developing the shoe last, the shoe last must be made at the same time. The back part of the shoe last and the front head shape part, and these two parts are conjoine...

[0002] The existing shoe last development is generally to choose a relatively close last according to the shoe shape, and then modify it, slowly repairing and adjusting from the head to the tail, which is time-consuming and laborious. There is no concept of dichotomy, and the scope of modification is too large , if a new last is developed, it must start from the head to the tail, and there is no concept of unified sharing of classification

Specifically, the development and production of the existing shoe last is usually a whole, that is to say, the back section of the shoe last and the head shape are integral and inseparable. Then, when developing the shoe last, the shoe last must be made at the same time. The back part of the shoe last and the front head shape part, and these two parts are conjoined and inseparable. Therefore, the back part of the existing shoe last and the front head shape of the shoe tree must be made in a single and complete way. Just to make a back part, you have to make a front part of the head shape. In this way, it will inevitably cause an increase in material costs, an increase in labor costs and waste. Moreover, the back part of each shoe last and the front head shape are both It is fixed and fixed, so the rear part and the front head shape cannot be flexibly selected and matched. If you want to match a new suitable shoe last, you must recreate a new complete rear part and shoe last. The front head shape, in this way, increases the repetitive work and material cost, and is not convenient for the overall design and development of the shoe last, and is not convenient for matching and selection
