Description

Mold structure with cloth sole

technical field

The utility model relates to a mold for manufacturing shoe soles, in particular to a mold structure with cloth layer soles.

Background technique

The molds commonly used to manufacture shoe soles are mainly injected with plastic into the cavity of the mold, and then injection molded through the mold to form the shape of a shoe sole. Therefore, the commonly used mold structure for shoe soles is mainly made by injecting rubber into one piece. However, the range of exposed plastic materials that can be molded out of the sole structure is too large, and foreign countries impose high taxes on plastic items, resulting in huge and heavy tariff fees when exporting, which in turn increases product costs. In addition, the appearance of the soles molded by commonly used sole molds is all plastic in shape and shape, which will make the appearance appear monotonous and lack of variability, and there is a need for improvement.

Contents of the invention

The purpose of this utility model is to provide a mold structure with a cloth sole to solve the above-mentioned traditional technical problems, to facilitate the positioning and fixing of the cloth body, to avoid the movement of the cloth body during injection mold molding, and to be able to use According to the needs of different sports modes and different sports environments, by matching different materials and the protruding retaining wall, it can be formed at a specific position on the sole to form the required sole structure and meet the diverse needs of users. .

Technical features for solving the problem: a mold structure with a cloth layer sole, characterized in that it includes:

an upper mold provided with several plastic injection channels; and,

A lower mold, the lower mold includes a molding cavity for injection of plastics for molding, one end of the lower mold is pivotally connected with one end of the upper mold, and a cloth that can be positioned is protruded in the molding cavity of the lower mold The protruding cloth retaining wall of the body has a height capable of accommodating and limiting and fixing a cloth body.

Wherein, the protruding cloth retaining wall is a closed annular retaining edge.

Wherein, the protruding cloth retaining wall includes at least two arc segments.

Wherein, the height of the protruding cloth retaining wall is greater than 0.8mm.

Efficacy compared to previous techniques:

1. The lower mold used in the utility model is provided with a protruding cloth retaining wall, through which the protruding cloth retaining wall can be conveniently positioned and fixed, effectively avoiding the cloth body from moving during injection into the mould, resulting in Change the relative position of the cloth body on the sole structure.

2. The upper and lower molds of the present utility model can be formed on specific positions of the soles by matching different materials and the protruding cloth retaining wall according to the user's different exercise mode requirements and different exercise environments, forming the desired shape. The required sole structure can meet the diverse needs of users.

3. The upper and lower molds of the utility model can not only be filled with ordinary plastic to directly form the outsole of shoes, but also can be inserted into a cloth body, such as non-woven cloth, and then fixed by the protruding cloth retaining wall, and then injected with plastic , effectively making the mold use function more diversified.

4. The sole structure formed by the upper and lower molds of the present utility model can effectively reduce tariffs by using the cloth body as a part of the appearance of the sole, so as to reduce the cost of the product and increase the aesthetic feeling of the appearance of the sole, color change and variability.

5. The sole structure formed by the upper and lower molds of the present invention is designed with a structure such as thermoplastic elastomer (TPE), which can achieve good air permeability, light weight and no sewing.

About technology, means and effect thereof that the present utility model adopts, preferred embodiment is cited hereby and cooperates drawing to describe in detail as follows, believe that the above-mentioned purpose of the present utility model, structure and feature thereof, when can get a deep and concrete by it understanding.

Detailed ways

Please refer to Fig. 1-Fig. 3, the utility model provides a mold structure with a cloth sole, comprising: an upper mold 10 and a lower mold 20. Wherein, the upper mold 10 is provided with several plastic injection channels 11, and the plastic can be thermoplastic elastomer (thermoplastic elastomer rubber, TPE), thermoplastic rubber (thermoplastic rubber, TPR) or thermoplastic polyurethane (thermoplastic polyurethane, TPU). etc.; the lower mold 20 includes a molding cavity 21, one end of the lower mold 20 is pivotally connected with one end of the upper mold 10, and the lower mold 20 is further provided with a protruding stop cloth in the molding cavity 21 Wall 22, the protruding cloth retaining wall 22 has a height, which can be used to accommodate and fix a cloth body 30, the cloth body 30 can be cloth body such as non-woven fabric, and the molding cavity 21 is used for injecting plastic molding A shoe sole 40, so that when the plastic is injected between the upper mold 10 and the lower mold 20 for molding, the protruding cloth retaining wall 22 can position the cloth body 30, and the cloth body 30 will not be generated in the plastic injection Changes in the relative position of the sole 40.

Wherein, the protruding cloth retaining wall 22 is a closed and annular retaining edge or can be in various other shapes.

Wherein, the protruding cloth retaining wall 22 includes at least two arc segments 221 .

Wherein, the height of the protruding cloth retaining wall 22 is greater than 0.8 mm.

In summary, firstly, the lower mold used in the utility model is provided with a protruding cloth retaining wall, through which the protruding cloth retaining wall can be conveniently positioned and fixed, effectively avoiding Moving, deriving results in changing the relative position of the fabric on the sole structure. Secondly, the upper and lower molds of the present utility model can be formed on specific positions of the soles by matching different materials and the protruding cloth retaining wall according to the user's different exercise mode requirements and different exercise environments, forming all the molds. The required sole structure can meet the diverse needs of users. Furthermore, the upper and lower molds of the present utility model can not only pour ordinary plastics directly into the outsole of shoes, but also can be inserted into a cloth, such as non-woven cloth, and then fixed by the protruding retaining wall, and then injected Plastic, which effectively makes the mold use function more diversified. In addition, the sole structure molded by the upper and lower molds of the present utility model can effectively reduce tariffs by using the cloth body as a part of the appearance of the sole, so as to reduce the cost of the product and increase the aesthetic feeling of the sole appearance, color change and variability. Finally, the sole structure formed by the upper and lower molds of the present invention is designed with a structure such as thermoplastic elastomer (TPE), which can achieve good air permeability, light weight and no sewing.

The foregoing is a specific description of the technical features of the utility model for the feasible embodiments of the utility model; those who are familiar with this technology can change and modify the utility model without departing from the spirit and principles of the utility model, and such Changes and modifications should be included in the scope defined by the patent scope of this application.
