Description

A kind of upper surface molding and upper bottom synthesis method

technical field

The invention relates to a method for but not limited to the formation of leather shoe uppers and the synthesis of upper soles.

Background technique

With the development of the market economy, the production process of footwear is also gradually moving towards modern production. The improvement of people's living standards and quality of life will effectively promote the rapid development of the leather shoe industry, and will fundamentally accelerate the change of footwear design and production methods.

For a long time, in the production process of footwear products, shoe lasts have been used as an auxiliary tool to complete the upper surface forming and upper sole synthesis technology. This method requires a large number of shoe lasts. At the same time, each style of footwear products has its own The corresponding special shoe lasts make the production cost of footwear high, and shoe companies need to keep a large number of shoe lasts for replenishment and reproduction. It has greatly restricted the rapid development of enterprises to technology and modern production.

Footwear technicians have little research and development and technological innovation in terms of upper forming and upper sole synthesis technology. Most of them are to improve production quality or production efficiency, improve some processes and production steps, and do not change the upper forming and upper sole. The main idea of synthesis, the upper forming and upper sole synthesis method described in the present invention, is a new production process without the aid of a shoe last to complete the production process of footwear products, which has not been described in the existing related technical fields.

Contents of the invention

Aiming at the shortage of existing technologies in the footwear industry, the purpose of the present invention is to provide a method for upper forming and upper sole synthesis, to change the production technology of this process, thereby improving the working efficiency of upper upper forming and upper sole synthesis processes , Give up the dependence on shoe last in production, and achieve the purpose of reducing the production cost of footwear products (shoe last cost).

In order to achieve the above purpose, the technical solutions adopted in the present invention include: hinged midsole technology, inflatable support technology, upper surface forming and upper sole synthesis production process.

The hinged midsole technology is the main tool for bottom support in the process of forming the upper and synthesizing the upper, which includes a special midsole and a hinged upper device.

The inflatable support technology is the main tool for upper support in the process of forming the upper and synthesizing the upper, which includes the upper support body and the main heel shaping body;

The production process of upper shaping and upper bottom synthesis is the operation steps of upper upper shaping and upper bottom synthesis by using the above tools in the production and application process of the present invention.

In a preferred technical solution, the special midsole is equipped with a shank part, and is shaped by the curved surface of the sole. There are a plurality of positioning holes on the edge of the midsole, and the positioning holes can correspond to the corresponding parts of the hinged upper device.

In a preferred technical solution, the outer contour of the hinged upper device is basically the same shape as the special midsole, and is composed of a plurality of hinge bodies, each hinge body is connected, and can move vertically and horizontally. Locating nails matching the locating holes;

Wherein, the hinge body can be decomposed and combined, and can be divided into general hinges and nailed hinges.

In a preferred technical solution, the upper support body is composed of a sole support body and an inflatable support body. During the formation of the upper surface and the synthesis of the upper bottom, the upper part is connected with the hinged upper device and the special midsole, and the lower part is connected with the upper part. The inflatable support body is connected, and the rear part is connected with the main heel shaped body to form an auxiliary tool for shoe cavity molding in the upper molding process;

Wherein, the longitudinal curve of the sole support body is the same as that of the special midsole, and its length and fatness are smaller than that of the special midsole;

Wherein, the inflatable supporting body is an airbag structure, and is inflated or exhausted through the inflatable port. When inflated, the upper can be supported, and when exhausted, the upper can be removed.

In a preferred technical solution, the shaped body of the main heel is similar in shape to the back of the shoe, is larger than the main heel, can be connected with the sole support body, and is made of metal.

In a preferred technical solution, the operation steps of forming the upper and synthesizing the upper are as follows: after the special midsole is formed, install the hinged upper device, place it on the upper part of the upper support, install the main heel shaped body on the sole support At the rear of the body, at the same time, install the main heel on the upper part, put the upper part into the upper surface support body, inflate the inflatable support body, brush glue on the upper corner of the midsole, and carry out the bonding process of the upper part and the midsole. After finishing the pre-bonding with the sole at the same time, the upper and the sole are bonded, after the shaping treatment, the air is exhausted, the shoe is removed, and the hinged upper device is taken out. Finally, the shoe is finished to complete the molding of the shoe upper and Helps with synthetic operations.

implementation plan

As shown in Figure 1, Figure 2, Figure 3, Figure 4, and Figure 5, align each hinge body 21 in Figure 2 with the edge of Figure 1, and after a plurality of positioning nails 20 fork into the corresponding positioning holes 10, insert The upper surface of the bottom is docked with the sole support body 40 in Fig. 4, and the main heel shaping body in Fig. 5 is mounted on the rear portion of the sole support body 40 to complete the auxiliary tool for forming the inner cavity of the shoe.
