Process for manufacturing shoes

Abstract

A shoe manufacture method comprises the following steps: preparing a die including a first die holder, a second die holder and an upper cover respectively pivoted on the first die holder, a shoe last die cavity arranged between the die holders for allowing one shoe last to be arranged therein and separated therefrom, and a sole die cavity arranged on the upper cover and closed with the shoe last; preparing a shoe upper and a sole unit; arranging the shoe upper sheathed on and bonded with the shoe last in the shoe last die cavity together with the sole unit; closing the die, heating and pressing to bond the shoe upper and the sloe unit to one shoe; cooling; and opening the die to take out the shoe. The shoe manufacture method has improved production efficiency.

Description

technical field [0001] The invention relates to a manufacturing method, in particular to a shoe manufacturing method. Background technique [0002] In view of the many deficiencies in the previous shoe-making methods, the creator created, applied for and has been approved for the invention patent case No. 90120234 "Manufacturing method of foam shoe body integral molding" in Taiwan Province of China, such as figure 1 , 2 As shown, the patent contains the following steps: [0003] (a) Prepare an upper 11 and a sole unit 12, the upper 11 is combined with at least one piece of material by sewing, the sole unit 12 has a midsole embryo 13 and a shoe outsole 14; [0004] (b) set the shoe upper 11 on a shoe last 21, and fix it by a pair of shoe last clamping molds 22, and the shoe last 21 is fixed on a shoe molding machine (not shown in the figure); [0005] (c) Coating glue on the top surface of the shoe outsole 14, the outer surface of the shoe upper 11 protruding from the shoe...

AI Technical Summary

Problems solved by technology

[0012] 1. Because the components of the forming mold 23 are designed separately, and the shoe last 21 is installed and fixed on the shoe forming machine, when the forming mold 23 is closed, the shoe last 21 cannot be accurately compared to the forming mold 23 Positioning, resulting in burrs after the thermocompression bonding operation is completed, so trimming operations are required to obtain the finished shoe body

[0013] 2. Because the components of the forming mold 23 are designed separately, after changing the forming mold 23 of different specifications, it is necessary to perform calibration and fine-tuning before entering the thermocompression combined molding process. In practice, the overall process takes a long time and affects Productivity needs to be improved

[0014] 3. Since the shoe upper 11 and the shoe midsole embryo 13 need to be pasted in different steps, and the forming mold 23 needs to be molded as separate components, resulting in many peripheral matching machines and equipment, The need for improvement requires high precision, resulting in high production costs
