Description

A new type of shoe sole and its production mold

technical field

The utility model relates to the technical field of footwear accessories, in particular to a novel shoe sole and a manufacturing mold thereof.

Background technique

Shoes were originally a tool for people to protect their feet, but in contemporary society, the function of shoes has gone far beyond that. With the improvement of people's living standards, people have higher requirements for shoes. In addition to their protective effect on shoes, they also pay more attention to the comfort and fashion of shoes. In order to improve the comfort of shoes and be suitable for the needs of people walking for a long time, the soles of many shoes currently have a certain shock-absorbing function.

At present, in the footwear industry, due to the advantages of PU degradability and good elasticity, PU foam soles are currently the most commonly used soles. In addition to the above advantages, the low density and low hardness of foamed PU can reduce the weight of the sole and increase the elasticity of the sole; however, the sole of this material will wrinkle, sink and deform in a short period of time; therefore How to achieve the purpose of reducing the weight of the sole and increasing the elasticity and ensure that the quality of the sole is not affected is an urgent problem to be solved at present.

Utility model content

In order to overcome the deficiencies of the prior art, the purpose of this utility model is to provide a new type of sole to increase the elasticity of the sole, reduce the weight of the sole and meet the requirements of durability and no wrinkles.

A new type of sole, including a wear-resistant outsole and a midsole, the outsole fits under the midsole or wraps around the outer surface of the midsole from the bottom surface and sides, and the midsole corresponds to the position of the heel or/and the sole of the foot The position is poured with elastic body, and the midsole is provided with several depressions to form a honeycomb structure.

Further, the midsole is also provided with a through hole penetrating the bottom.

Specifically, the material of the outsole is one of wear-resistant rubber, TPR, TPU, TR and other wear-resistant materials.

Specifically, the midsole is made of PU foam material.

Specifically, the elastic body is a spring ring or a transparent elastic member filled with a spring ring.

Another object of the present invention is to provide a manufacturing mold for a novel shoe sole, which includes a large bottom mold and a middle bottom mold; The cavity, the upper cover or the base are provided with convex cylinders to form the concave part of the midsole.

Further, the cavity is provided with elastic recesses or protrusions or magnets at positions corresponding to the heel or/and the sole of the foot.

Further, the outsole is a sheet-shaped or hollow sole with accommodating chambers.

Compared with the prior art, the beneficial effects of the utility model are:

1. In this utility model, the wear-resistant outsole can protect the PU midsole, prevent the hydrolysis of the midsole, and prolong the service life of the sole;

2. The midsole of the present invention forms a honeycomb hollow structure by setting the concave part, which reduces the consumables and greatly reduces the weight of the sole; and the force point in the midsole is filled with springs, which increases the resilience and parallel force , so that the sole becomes hollow and does not pile up.

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment.

detailed description

A new type of sole, including a wear-resistant outsole 1 and a midsole 2, the outsole 1 is fitted under the midsole 2 or wrapped around the outer surface of the midsole 2 from the bottom surface and sides, and the midsole 2 corresponds to the heel The position or/and the position corresponding to the sole of the foot is filled with elastic body 3, and the midsole 2 is provided with several depressions 21 to form a honeycomb structure. In the utility model, the concave part forms a honeycomb hollow structure, which not only reduces consumable materials but also greatly reduces the weight of the sole.

Further, the midsole is also provided with a through hole penetrating the bottom. The purpose of setting the through hole is to further reduce the weight of the sole and enhance the air permeability of the sole.

Specifically, the material of the outsole is one of wear-resistant rubber, TPR, TPU, TR and other wear-resistant materials.

Specifically, the midsole is made of PU foam material.

Specifically, the elastic body is a spring ring or a transparent elastic member filled with a spring ring.

Another object of the present invention is to provide a manufacturing mold for a novel shoe sole, which includes a large bottom mold and a middle bottom mold; The cavity, the upper cover or the base are provided with convex cylinders to form the concave part of the midsole.

Further, the cavity is provided with elastic recesses or protrusions or magnets at positions corresponding to the heel or/and the sole of the foot. The elastic body can be fixed in the mold cavity by a concave position or a convex position or a magnet, so as to prevent the elastic body (such as a spring) from shifting when the midsole is made by pouring.

The following are specific embodiments of the utility model.

Example 1

A new type of sole, including a wear-resistant rubber outsole and a PU foam midsole, the outsole is wrapped on the outer surface of the midsole from the bottom surface and sides, and the midsole is at the position corresponding to the heel and the sole The elastic body is poured, and the midsole is provided with a plurality of depressions to form a honeycomb structure.

This novel sole is made by following method, adopts the manufacturing mold described in the utility model, and the steps are as follows:

1) Making the outsole: forming the outsole in the outsole mold, and forming a cavity for the midsole in the outsole;

2) Making the midsole: Put the above-mentioned outsole with accommodating cavity into the cavity of the midsole mold base, place elastic parts (such as spring rings) in the outsole corresponding to the stress points of the heel and forefoot, and then Inject the PU foam material into the cavity of the outsole, cover the upper cover of the mold, and open the upper cover after the foaming is completed, and trim the corners to obtain a new type of sole.

Further, the outsole can also be made into a sheet shape, and at this time, there is no need for an accommodation cavity. During processing, the large bottom is put into the midsole mould, and after the midsole is produced according to the above step 2), the large bottom and the midsole are bonded into a sole.

Further, it is also possible not to put the big bottom into the midsole mold, and to produce the midsole by the method of step 2), and then attach the midsole and the big bottom to form a sole.

Example 2

A new type of shoe sole, including a wear-resistant rubber outsole and a PU foam midsole, the outsole is wrapped around the outer surface of the midsole from the bottom surface and sides, and the midsole is filled with elastomer at the corresponding position of the heel. The midsole is provided with several depressions to form a honeycomb structure. In this embodiment, the elastic body can also be poured into the corresponding position of the sole of the foot.

The difference between the manufacturing method of the new sole described in this embodiment and the first embodiment above is that the elastic body is placed at the position corresponding to the stress point of the heel.

Example 3

A new type of shoe sole, including a wear-resistant rubber outsole and a PU foam midsole, the outsole is fitted under the midsole, the midsole is filled with spring coils at the position corresponding to the heel, and the midsole is Several depressions are provided to form a honeycomb structure.

This novel sole is made by following method, adopts the manufacturing mold described in the utility model, and the steps are as follows:
