Problems solved by technology

[0002] At present, the insole used in the shoe-making industry, its manufacturing process includes cutting the base material, thickening and bonding the heel, and pressing the molding process. The insole is made by cold processing, and the molding effect is not good. The fit between the insole and the last is not enough, and the gap between the insole and the last is large, which may easily cause the appearance of the finished shoe to be poor, and the wearing comfort cannot fully meet the design requirements of the last

Abstract

The invention discloses a preparing method of a hemp forming insole. The preparing method comprises the following steps of a, cutting a hemp material into an insole shape according to the shape of a shoe tree, and punching a heel end surface of the material to an insole opening by a punching knife; b, punching a hole on one front side of the material according to the size of an ABS (acrylonitrile butadiene styrene) injection opening, for injecting the ABS; c, putting the cut insole in a die, wherein the temperature of the die is 55 to 75 DEG C, and ABS resin is injected into the reserved hole by the ABS injection opening aligning with the reserved hole; and d, closing the die and pressurizing, wherein the pressure is 30kgf / cm<2>, and the pressurizing time is 5 to 6 minutes; and opening the die, and cleaning. The preparing method has the advantages that the insole is injected and molded by one-time forming, the inner structure of the insole material deforms at high temperature and high pressure through the heat treatment effect during processing, and then the insole material is subjected to secondary forming, so the insole completely meets the requirements of the shoe tree, and is more closer to the structure of a foot; a finished shoe made by the hemp insole prepared by the method is more comfortable in wearing, the elasticity and the original shape can be maintained after the finished shoe is worn for a long time, the iron cores are not needed, the weight is reduced by 30% in comparison with the traditional mid-sole, and the comfortable degree is higher.

Description

technical field [0001] The invention belongs to an inner bottom, and in particular relates to a preparation method of an inner bottom with one-time molding, which is convenient for subsequent shoe-making process operation, has high flatness, light weight, and good antibacterial and deodorizing properties. Background technique [0002] At present, the insole used in the shoe-making industry, its manufacturing process includes cutting the base material, thickening and bonding the heel, and pressing the molding process. The insole is made by cold processing, and the molding effect is not good. The fit between the insole and the shoe last is not enough, and the gap between the insole and the last is large, which may easily cause the appearance of the finished shoe to be poor, and the wearing comfort cannot fully meet the design requirements of the shoe last. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned deficiencies a...
