Abstract

A Waterproof air pervious shoe sole internally provided with an air pervious film buckle is formed by secondarily pressing, adhering, molding and integrating an upper shoe sole surface (1), a lower sole undersole (2), and a middle waterproof air pervious film (8). Multiple grooves (3) are distributed in the upper surface of the sole undersole (2). At least one through hole (4) leading to the bottom of the shoe undersole is formed in the bottom of each groove. Holes (5) corresponding to the grooves in the upper surface of the shoe undersole are formed in the shoe sole surface (1). Multiple lower fixing columns or lower fixing slots (6) reserved for secondary molding are distributed on the upper surface of the sole undersole (2). Upper fixing slots or upper fixing columns (7) corresponding to the lower fixing columns or lower fixing slots (6) on the upper surface of the shoe undersole are formed on the shoe sole surface (1). Hollow holes (9) corresponding to the lower fixing columns or lower fixing slots (6) on the upper surface of the shoe undersole are formed in the waterproof air pervious film. The shoe sole can well fix the film buckle without being repeatedly glued and is good in waterproofing effect; the automation degree can be greatly improved.

Description

Waterproof and breathable sole

Technical field

The utility model relates to a waterproof and breathable sole, in particular to a waterproof and breathable sole with a gas permeable membrane buckle.

Background technique

The inventor of the present application obtained a Chinese utility model patent entitled "A waterproof and breathable sole", patent number ZL201120491351.9, which is characterized in that: a plurality of grooves are distributed on the upper surface of the sole, and at least the bottom of the groove is open at least A through hole is formed in the sole, and a film buckle is mounted in the groove. The film buckle structure is: a ring having a shape corresponding to the groove, and at least one waterproof gas permeable film is formed on the film buckle.

The waterproof and breathable membrane buckle on the sole improves the placement method of the sole cushioning waterproof and breathable membrane. However, in the application process of mass production, the following problems are found: 1. The fixed membrane buckle needs repeated rubber coating, and the waterproof fixing is cumbersome; 2. The degree of product automation is not high.

Utility model content

The technical problem solved by the utility model is to provide a waterproof and breathable sole with a gas permeable membrane buckle which can fix the film buckle well without repeated application of glue, and has good waterproof effect and can greatly improve the degree of automation.

To solve the above technical problems, the technical solutions adopted by the utility model are as follows:

The utility model relates to a waterproof and breathable sole with a gas permeable membrane buckle, which is characterized in that: the sole is integrated by the secondary sole 1 , the lower sole 2 and the middle waterproof breathable membrane 8 by secondary compression bonding; a plurality of grooves 3 are disposed on the upper surface of the outsole 2, and at least one through hole 4 is formed in the bottom of the groove to the bottom surface of the sole of the shoe, and the sole 1 is provided with a groove corresponding to the upper surface of the sole of the shoe. Hole 5.

On the basis of the above, the utility model can be further improved:

The upper surface of the shoe outsole 2 is provided with a plurality of sub-formed lower fixing posts or lower fixing slots 6 , and the sole 1 is corresponding to a fixed post or a lower fixing of the upper surface of the sole of the shoe. The upper fixing groove or the upper fixing column 7 of the groove 6 is provided with a boring hole 9 corresponding to the upper surface fixing post or the lower fixing groove 7 of the shoe sole.

It is also possible not to have a fixing column fixing groove, but only a waterproof gas permeable membrane is reserved at the position where it should be placed. The holes make the underside and the outsole easier to bond.

The sole of the shoe may be not only the sole of the foot but also the bottom of the whole shoe.

The shape of the sole groove is not limited to a regular shape such as a circular shape, a square shape, or the like, and may, in many cases, be based on an irregular shape which is most advantageous for ventilation.

Production process:

Firstly, a shoe outsole with a venting hole is formed at one time. In addition to the venting hole, the outsole has a corresponding fixing column or groove for secondary molding. Secondly, a waterproof and breathable film is placed, and the waterproof and breathable film is placed. The position of the fixed column or groove reserved for the outsole of the shoe is also corresponding to the pupil, and the waterproof film can be fixed at this time; then, the prefabricated mold A, the secondary molding is integrated into a shoe outsole, through the pre- The position of the retaining post or groove is such that the primary and secondary compression molded shoe soles are fused together and the waterproof gas permeable membrane is secured together. Thus forming a complete sole. Such a sole has excellent water repellency and is easy to handle and has stable production performance. At the same time, it is also suitable for different types of shoe materials, such as rubber, PU, EVA, TPR, TPU and other injection molding.

The shoe sole film double molding method reduces the manufacturing cost of the sole film buckle, makes the production easier, and further improves the waterproof performance.

Beneficial effects: Since the sole is divided into two layers, it can be separately manufactured, and finally pressed, which can fix the film buckle well, has good waterproof effect, and greatly improves the degree of automation.

detailed description

As shown in FIG. 1 to FIG. 3, the waterproof and breathable sole of the utility model has a breathable membrane, and is formed by the upper layer of the sole 1 , the lower sole 2 of the lower layer, and the waterproof and breathable membrane 8 in the middle. A plurality of grooves 3 are arranged on the surface of the upper side of the shoe, and at least one through hole 4 is opened at the bottom of the groove until the bottom surface of the sole of the shoe. The shape of the through hole is not limited to a regular shape such as a circle or a square, and may also be a majority The case is based on an irregular shape that is most favorable for ventilation, and the sole 1 is provided with a groove corresponding to the upper surface of the sole of the shoe. In order to adhere firmly, a plurality of sub-fixed lower fixing posts 6 are disposed on the upper surface of the sole of the shoe, and the upper surface of the shoe has an upper fixing groove 7 corresponding to the upper and lower fixing columns on the upper surface of the sole of the shoe, and the waterproof and breathable film is opened. There is a bore 9 corresponding to the upper surface fixing post or the lower fixing groove 6 of the shoe sole.

If the thermal bonding is used, the lower fixing post 6 on the upper surface of the outsole and the upper fixing groove 7 on the sole of the shoe may not be used, and the waterproof and breathable film does not need to be corresponding to the upper or lower fixing groove 6 of the upper sole of the shoe. Pupil 9.

The bottom surface of the sole of the embodiment is only the sole surface of the sole. In fact, the entire sole can be divided into two upper and lower layers. In addition, the upper surface of the sole of the shoe may also be provided with a plurality of lower fixing grooves reserved for secondary molding, the sole surface. An upper fixing post corresponding to the fixing groove under the upper surface of the sole of the shoe is opened.
