Embodiment Construction

[0031] In order to illustrate the idea and purpose of the present invention, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] A kind of manufacturing method of shock-absorbing air cushion for shoes of the present invention, it comprises the following steps:

[0033] A. Provide injection mold;

[0034] B. Inject the thermoplastic into the injection mold through the injection molding process. After the thermoplastic is cooled, an upper air cushion 1 and a lower air cushion 2 are formed in the two molding spaces of the injection mold, and the upper air cushion 1 and the lower air cushion 2 Separately formed support structures with variable appearance that can be designed and changed according to the stress points of the soles of the feet in different sports;

[0035] C. Open the mold, and demould the prepared air cushion upper sheet 1 and air cushion lower sheet 2;

[0036] D. Add the air nozzle 3 on ...

Abstract

The invention discloses a shock-absorption air cushion for a shoe and a manufacturing method for the shock-absorption air cushion. The manufacturing method comprises the following steps of: providing an injection mold first; injecting thermoplastic plastic into the injection mold through a shooting technique; respectively forming an upper air cushion sheet and a lower air cushion sheet in two forming rooms of the injection mold after the thermoplastic plastic is cooled; opening the mold; releasing the manufactured upper air cushion sheet and the manufactured lower air cushion sheet from the mold; adding an air tap on the upper air cushion sheet or the lower air cushion sheet; combining the upper air cushion sheet and the lower air cushion sheet; sewing the upper air cushion sheet, the lower air cushion sheet and the air tap together by radiofrequency hot melting; then cutting off leftover materials; and finally adding different air pressures to the shock-absorption air cushion through the air tap. After the shock-absorption air cushion is formed, the quantity of the leftover materials required to be cut off is small, so that materials are saved; the internal shape and the internal structure of the shock-absorption air cushion are respectively formed by the upper air cushion sheet and the lower air cushion sheet by injection moulding; after the upper air cushion sheet, the lower air cushion sheet and the air tap are sewn together by radiofrequency hot melting, and the stability of the shock-absorption air cushion is high; the internal shape of the shock-absorption air cushion can be freely changed according to demands of customers; and moreover, the color of the upper air cushion sheet and the color of the lower air cushion sheet are different and are separated in the up-down direction.

Description

technical field [0001] The invention relates to the technical field of footwear processing, in particular to a method for manufacturing a shock-absorbing air cushion for shoes and the shock-absorbing air cushion. Background technique [0002] Conventional footwear consists of two main components, an upper and a sole structure. The sole structure generally exhibits a layered structure, which includes an insole for enhanced comfort, a midsole for shock absorption, and an outsole for providing friction and contacting the ground. In order to enhance the shock-absorbing effect of the midsole of the shoe, people often add a shock-absorbing air cushion in the midsole of the shoe. [0003] Currently, shock-absorbing air cushions can be manufactured by blow molding. Its manufacturing method is generally as follows: the softened thermoplastic material is placed in a mold with the desired shape and configuration, and the opening of the mold is filled with pressurized air. The pressur...
