Description

Combined shoe manufacturing process

The present invention relates to a process for making a shoe material, and more particularly to a method for manufacturing a shoe sole.

In daily life, it is necessary to rely on the feet to support the weight of the whole body. The basic movements of standing and walking will have a huge burden on both feet. All of the above actions need to rely on the large amount of gravity changes on both feet. Today, the public has long been accustomed to wearing shoes to go out, whether it is simply going out, outdoor activities or even intense sports. The shoes not only protect the shoes, but also provide stable walking and pedaling, slowing down the reaction of various postures and even sports to the feet, overcoming discomfort and pain.

The bottom of the shoe is often in contact with the ground, frictional forces, and withstands the effects of weight from the human body and from ground activities. In the past, most of the soles were made of a single foam material, and the mold holes of the mold were used to create a unique pattern, or another coloring method to create a unique visual effect. However, the general coloring is nothing more than printing, spraying, etc., and its durability is quite limited. Therefore, related manufacturers use two-color foam or two-color injection technology to make the sole, changing the single tone of the sole.

However, when two-color foaming is used to make a sole, coloring problems often occur, and the separation between the two colors is not clear enough, for example, as shown in the tenth figure. In the picture The two-color soles are mostly made by first making the sole of the first color and then placing it in the foaming mold. Under the condition of high temperature foaming, the sole of the first color is prone to hot melt, which causes the surrounding to soften and even Part of the circumference or surface begins to be thick, so that the foamed material is sent to the mold cavity for foaming, and the softened first color of the sole has to withstand the foaming pressure, resulting in easy entry of the second color of the foamed shoe material. To the position of the cavity which should belong to the first color shoe material, the edge of the two colors is not sufficiently obvious, resulting in a so-called color overflow problem.

The invention provides a combined shoe material manufacturing process, which improves the problem that the sole of the prior art is easy to have an overflow color, and the segmentation is not obvious enough, and the combined shoe material can be made into a novel sole.

In order to achieve the foregoing objects and effects, the present invention provides a combined shoe material process comprising the steps of: first foaming, filling a first particle in a cavity of a first foaming mold, and first particles in the first hair The cavities of the bubble mold are foamed and arranged in a granular arrangement to adhere to each other on the circumferential side, so that the first particles correspond to the cavity of the first foaming mold and are foamed to form the first portion of the shoe material, and the guide post of the corresponding cavity is formed. Hole; hot pressing fit, taking out the first part of the shoe material from the first foaming mold, respectively placing the first part of the shoe material and the balance piece on the bonding mold, and the balance piece is stacked on the first part of the shoe material, and the balance piece has Passing through the protruding post of the through hole, heating and laminating the mold to 110 ° C ~ 150 ° C, so that the surface of the balance sheet is thermally dissolved and bonded to the surface of the first part of the shoe material, and the surface of the stud of the balance sheet is thermally coupled to the pass The hole wall of the hole; the second foaming, the first part of the shoe material and the balance piece which have been completely combined with the hot melt are taken out from the bonding mold and placed in the first a second foaming mold, filling the second particles in the cavity of the second foaming mold and stacking on the balance sheet and foaming, so that the second particles correspond to the foam molding between the cavity and the balance sheet of the second foaming mold a second portion of the shoe material, and the second particles are in a granular arrangement and adhere to each other on the circumferential side and adhere to the balance sheet, thereby forming a combined shoe material and being taken out from the second foaming mold; the first particle and the second particle color Not the same.
