Processing method of breathable shoes

Abstract

The invention discloses a processing method of breathable shoes. The processing method comprises a shoe sole preparation process and a shoe-pad preparation process. The shoe sole is individually prepared through an integrated injection molding technology adopting a shoe sole mold. The heelpiece of the molded shoe sole is provided with a pit. The shoe-pad preparation process is characterized in that a fabric layer of an upper surface of a shoe pad is preliminarily bonded to an elastic gas bag by a silicon sheet, the front end of the elastic gas bag is connected to a gas inlet pipe, a position of a shoe pad mold corresponding to a closed end of the gas inlet pipe is provided with a positioning slot, the closed end of the gas inlet pipe is inserted into the positioning slot, a position of the shoe pad mold corresponding to an exhaust valve installation hole is provided with a positioning raised column, the elastic gas bag, the gas inlet pipe, the fabric layer and the silicon sheet are fixed to the shoe pad mold by the positioning raised column and the positioning slot, PU as a shoe pad main material is poured into the shoe pad mold and then foams and is molded, the molded shoe pad is released from the shoe pad mold, the closed end of the gas inlet pipe is opened by cutting, and the heelpiece of the molded shoe pad is provided a raised column matching the pit of the molded shoe sole.

Description

technical field [0001] The invention relates to a processing method of air-permeable breathing shoes. Background technique [0002] Most of the existing breathable breathing shoes are processed after the sole or insole is formed, and then reserve or dig out a pit at the heel of the sole or insole, then install the elastic airbag in the pit, and then pass through the one-way air intake valve and the one-way valve. The air in the shoe and the air outside the shoe can be exchanged through the exhaust valve. The breathable breathing shoes obtained by this processing method are likely to have a gap between the elastic airbag and the pit, and the elastic airbag and the pit will be damaged. The integrity of the sole or insole affects the strength of the sole or insole. In the existing breathable processing method, the elastic airbag is pre-embedded in the sole or insole, and then the sole or insole is integrally formed. Although the resulting The strength of the sole or the insole...

[0002] Most of the existing breathable breathing shoes are processed after the sole or insole is formed, and then reserve or dig out a pit at the heel of the sole or insole, then install the elastic airbag in the pit, and then pass through the one-way air intake valve and the one-way valve. The air in the shoe and the air outside the shoe can be exchanged through the exhaust valve. The breathable breathing shoes obtained by this processing method are likely to have a gap between the elastic airbag and the pit, and the elastic airbag and the pit will be damaged. The integrity of the sole or insole affects the strength of the sole or insole. In the existing breathable processing method, the elastic airbag is pre-embedded in the sole or insole, and then the sole or insole is integrally formed. Although the resulting The strength of the sole or the insole is higher than the strength of the sole or the insole in the aforementioned method, but this integrally formed sole or insole is a structure with a flat bottom surface. The interaction between the insole and the insole will tilt to one side, which will cause the force of the elastic airbag to be concentrated on one side, which will easily cause the elasticity of the elastic airbag to fail, unable to recover automatically, and lose the effect of ventilation and breathing. The service life is long. Most of the existing breathable and breathing shoes are damaged firstly by the elastic airbag that brings the breathable and breathable function. Shoes or wearing shoes without breathability will affect the overall service life
