Abstract

The invention provides a production method for integrally forming shoes, which comprises the following steps of putting an outsole part at the bottom of a shoe mold, adding thermoplastic elastomer particles into the midsole of the mold, putting a shoe tree sleeved with a vamp into the mold, and closing the mold to realize sealing, wherein at the position close to the thermoplastic elastomer particles, the surface of the outsole part and the surface of the vamp are both covered with a permeation blocking material; hot melt adhesive films are placed at the interface of the outsole part and the midsole position and the interface of the midsole position and the vamp; and the Vicat softening point temperature of the thermoplastic elastomer particles is 50-140 DEG C. introducing gas into the sealed shoe mold, raising the temperature to enable the gas reaching the supercritical state to impregnate and saturate the thermoplastic elastomer particles, then releasing the pressure to form a foamedmidsole part, and meanwhile, realizing bonding of all shoe parts, and removing a shoe tree to obtain the whole shoe. The method is short in preparation process and high in efficiency; and the prepared shoes are high in resilience rate, low in density and beneficial to application.

Description

technical field [0001] The invention relates to the technical field of footwear manufacturing, in particular to an integrally formed footwear production method. Background technique [0002] In a narrow sense, sports shoes refer to the shoes that people wear when performing sports; traditional sports shoes production mainly includes outsole preparation, midsole foam molding, upper production and the assembly of the whole shoe (usually glued together) ). Among them, the main functions of the upper include: covering or wrapping the foot, providing support, protection, breathability, and ensuring that the foot is placed in the correct position. The upper or upper forms a space above the sole for receiving the foot, the space has the shape of the foot and has an ankle opening. The outsole refers to the layer structure that is in direct contact with the ground, usually made of natural rubber or artificial rubber, and has the functions of anti-slip, wear-resistant and bending-re...
