Description

Adjustable mould

Technical Field

The invention relates to the field of shoemaking, in particular to an adjustable mould for manufacturing insoles.

Background

The general current situation of the shoe making industry is that after rough approximate treatment is carried out on the foot shape of a person, shoes with consistent shoe shapes are produced in batches according to shoe sizes, namely, the shoes of the same type only have the difference of the shoe sizes. The insole is mainly used for matching with the sole to form a corresponding shape, supporting and fitting the foot, and improving the wearing comfort. But the prior insoles are produced in batches according to shoe sizes, and the shape and the thickness of the insoles are consistent. When the foot of the user is fat, thin, high arch or low arch, it is difficult to select a comfortable insole fitting the foot, and the insole cannot provide proper support for the foot.

The existing shoe pad manufacturing mode can not meet individual requirements according to the foot shape difference of people, and can not meet special requirements of special people (such as fat, thin, flat feet or high-arch feet).

Patent application No. 201720419744.6, entitled EVA insole mold for mass production, discloses a mold for mass production of insoles, but the shape and thickness of the insole produced by the mold are the same, and the insole cannot be customized individually, and the insole cannot be customized according to the specific foot shape of the user. There is a great need for an adjustable mold that can be used to produce customized insoles at a lower cost and in a shorter time.
