Manufacturing method of moisture-permeable and waterproof shoe with integrally coated sole

Abstract

The invention relates to a manufacturing method of a moisture-permeable and waterproof shoe with an integrally coated sole. The manufacturing method comprises the following steps: (A) sleeving a shoe tree with a moisture-permeable and waterproof shoe-shaped inner sleeve; (B) putting the shoe tree with the moisture-permeable and waterproof shoe-shaped inner sleeve into a first forming mold cavity of a first forming mold; (C) injecting a first foaming material into the first forming mold cavity so as to form an insole integrally connected with the moisture-permeable and waterproof shoe-shaped inner sleeve; (D) opening the first forming mold, and taking out the shoe tree with the moisture-permeable and waterproof shoe-shaped inner sleeve and the insole; (E) sleeving the shoe tree with the moisture-permeable and waterproof shoe-shaped inner sleeve and the insole with a vamp unit; (F) putting the shoe tree with the vamp unit, the moisture-permeable and waterproof shoe-shaped inner sleeve and the insole into a second forming mold cavity of a second forming mold; and (G) injecting a second foaming material into the second forming mold cavity to form a sole unit integrally connected with the vamp unit. Therefore, the fixed connection operation of the insole and the sole unit can be completed without manual gluing operation.

Description

technical field [0001] The invention relates to a shoe, in particular to a method for manufacturing a moisture-permeable waterproof shoe with a shoe sole integrally covered. Background technique [0002] Existing moisture-permeable waterproof shoes generally include a sock-like vamp, a waterproof inner cover fixed inside the sock-like vamp, and a sole fixed on the bottom side of the sock-like vamp. Wet waterproof shoes need manual gluing to fix the sole to the bottom side of the sock-like upper. However, this manual gluing method is not only cumbersome, but also produces glue residue and gluing. Pollution and environmental protection problems caused by the volatilization of the treatment agent will have adverse effects on the body of the operator. [0003] In addition, the waterproof inner cover is generally affixed with waterproof strips at the seams to enhance the waterproof effect. However, once the waterproof strips at the bottom seam of the waterproof inner cover are n...

[0003] In addition, the waterproof inner cover is generally affixed with waterproof strips at the seams to enhance the waterproof effect. However, once the waterproof strips at the bottom of the waterproof inner cover are not pasted, it will directly affect the waterproofness of the bottom of the waterproof inner cover. waterproof effect
