Manufacturing process of foamed midsole and outsole and upper part by adhesive molding using mold and high pressure inside hollow box

摘要

Name;A manufacturing method in which a foamed midsole, an outsole, and an upper are integrally formed by adhesive molding using a mold and a high pressure inside a hollow box.;assignment;In the method of producing the former upper, midsole, and outsole under separate conditions and bonding them under the integrated condition, the parts to be adhered are pre-treated, applied with adhesive, thermally dried, artificially attached, Since shoes were produced, equipment cost, large space, time and manpower were consumed excessively and it was uneconomical.;Solution;In one mold, air pressure was used to suppress expansion and expansion of the foamable resin by high temperature. The upper mold is replaced with the upper mold, and the foamed material is adhered to the lower surface of the upper mold so as to be adhered to the rubber layer on the lower surface.
