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.
