Abstract

A method for making a rubber shoe sole with an air cell includes: a first curing step including putting rubber raw material into a mould assembly to form a lower member and an upper member of the shoe sole; a second curing step including putting raw material at a conjunction of the lower member and the upper member, pressing the lower and upper members against each other, and hot melting the rubber raw material to bond the lower and upper members together, whereby to form the air cell between the lower and upper members after the lower and upper members are bonded together; and a finishing step including demoulding and trimming the lower and upper members which have been bonded together by hot melting, so that a final product of the rubber shoe sole with an air cell is obtained.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a shoe sole, and more particularly to a rubber shoe sole with an air cell and a method for making the same.[0003]2. Description of the Prior Art[0004]Normally, a shoe sole is made of rubber material due to the fact that rubber material is flexible, durable and bendable. However, the existing shoes sole made of rubber material are all solid structures due to technology limitation.[0005]To provide the rubber made shoe sole with better buffering capability, the existing shoe soles are mostly provided with air cells. The method of assembling the air cells is such that, the air cells are coated with a layer of adhesive, then dried with a dryer or directly put in the receiving chambers of a sole. After the air cells are adhered to the sole, the insole is glued to the air cells and the sole. This method is too complicate and seriously affects the manufacturing cost of the shoe sole.[0006]The pr...
