Embodiment 1

[0027] Embodiment 1: A kind of one-time extrusion ironing shaping process of shoe shape, comprises the following steps:

[0028] a. Use computer scanning technology to collect shoe last data, and then use computer engraving machine to carve the shoe last mold cavity, put the semi-finished shoe cover on the shoe last, and then put the shoe last head down into the shoe last mold;

[0029] b. Start the vertical piston cylinder and the horizontal piston cylinder of the extrusion ironing shaping machine once, and start the mold heating device of the extrusion ironing shaping machine at the same time to heat, extrude and iron the upper surface and inner lining materials. When the upper material is genuine leather, the temperature is controlled at 100°C to 125°C and kept warm for 5s;

[0030] c. Start the extrusion ironing and shaping machine once, the shoe last mold is opened, the piston cylinder returns to its original position, and the shoes are taken out.

Embodiment 2

[0031] Example 2: A process for one-time extrusion and ironing of shoe shapes. When the material of the semi-finished shoe upper is genuine leather, the temperature in step b is controlled at 115°C-122°C, and the temperature is kept for 8s. Other steps are the same as in Example 1.

Embodiment 3

[0032] Embodiment 3: One-time extrusion and ironing shaping process for shoe shape. When the upper material of the semi-finished product is genuine leather, the step b is kept warm for 8 seconds, and the other steps are the same as in embodiment 2.

Abstract

The invention discloses a shoe-shaped one-step extrusion, ironing and shaping process and special equipment thereof. The shoe-shaped one-step extrusion, ironing and shaping process comprises the following steps of: a, manufacturing a boot tree die, sleeving a semi-finished product shoe to be shaped on the boot tree, and placing the boot tree into the one-step extrusion and ironing boot tree die; b, heating the boot tree die and heating, extruding and ironing an opposite upper face and a lined material of the boot tree, wherein the temperature is controlled to be between 80 and 122 DEG C and the heat is preserved for 3 to 12 seconds; and c, opening the boot tree die and taking out the shoe. According to the technical scheme, the shoe-shaped one-step extrusion, ironing and shaping process and the special equipment thereof have the advantages that: due to the precision consistency of the boot trees with the same shoe size and the uniform consistency of the upper materials, the upper faceis extruded and ironed through the surface of the high-temperature smooth boot tree die, so that the upper and the vamp are attached to the boot tree, materials are redistributed, the internal organization structure of the upper material is improved, the boot tree has the visual effects of a smooth line, a dense and flat upper face and a harmonious upper face photorefractive effect, and the ironing effect of the upper face can be guaranteed.

Description

technical field [0001] The invention relates to a shoe shape shaping process, in particular to a shoe shape shaping process in one-time extrusion ironing in the shoe-making industry, and also relates to a one-time extrusion ironing shaping machine patented for the process. Background technique [0002] In the shoe industry, shaping the shoe shape can improve the stiffness of the upper surface, improve the visual effect of the shoe shape appearance, significantly improve the appearance quality of the shoe, and thus increase the added value of the product. The traditional shaping method after stretching of shoes and boots is: relying on manual beating, by applying external force intermittently to the upper of the shoe, and under the action of high temperature, the upper material is locally deformed intermittently to realize the shaping of the upper surface. The disadvantages of this type of method are: 1. The plastic effect is poor; 2. The labor efficiency is low and the labor...
