Embodiment Construction

[0018] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] refer to figure 1 1. A cushioning and shock-absorbing insole disclosed in an embodiment of the present invention, a TPU shock-absorbing insole, includes an insole body 1, a memory shock-absorbing layer 31 arranged on the bottom heel area of ​​the insole body 1, and the forefoot area. The bottom of the insole body 1 is provided with a support layer 4 at the arch of the foot, and the support layer 4 extends toward the heel area. The shock-absorbing groove that passes through the supporting layer 4. In order to wear more comfortably, the surface of the insole body is also provided with a cloth layer 5 .

[0020] The manufacturing method of the above-mentioned cushioning and shock-absorbing insole includes: a manufacturing method of the cushioning and shock-absorbing insole, including:

[0021] 1) Fix the prepared arch support layer on the arch...

Abstract

The present invention proposes a method for making cushioning and shock-absorbing insoles, including 1) fixing the arch support layer on the arch of the mold; 2) baking the memory shock-absorbing layer until it softens; 3) softening the softened The memory shock-absorbing layer is placed in the insole forming groove of the mold, the arch support layer is set at the arch of the memory shock-absorbing layer, and a hot-melt film layer is placed between the arch support layer and the memory shock-absorbing layer, and the mold is placed on the insole The bottom in the forming groove is also provided with a vacuum suction pump; 4), the vacuum suction pump carries out surface suction texture treatment to the bottom surface of the arch support layer and the forefoot and heel of the memory shock absorbing layer respectively. The arch support layer is thermally compounded on the arch position of the memory shock-absorbing layer according to the temperature and pressure of the blister and the heat-melt effect of the hot-melt film layer, and the memory shock-absorbing layer compounded with the arch support layer is obtained; 7), Cutting step, 8), put the memory shock-absorbing layer compounded with the support layer into the injection mold and inject the insole body.

Description

technical field [0001] The invention relates to the technical field of insoles, in particular to a method for making cushioning and shock-absorbing insoles. Background technique [0002] Most of the common insoles on the market are made of solid structure, and the physical properties of materials such as EVA are used for cushioning. However, due to the limited performance of the material itself, there is a compression limit and a rebound limit that cannot respond quickly after being impacted by the sole of the foot. , and after a period of use, the material ages and collapses, and cannot play the role of cushioning and shock absorption; the insole has poor air permeability, which easily causes the soles of the user to sweat. [0003] Therefore, if figure 1 , the inventor has studied a TPU shock-absorbing insole, including an insole body 1, a memory shock-absorbing layer 31 arranged on the heel area and the forefoot area of ​​the bottom of the insole body 1, and the bottom o...
