Technical Field

The invention belongs to the field of shoemaking processes, and particularly relates to a novel attractive and simple sole making process.

Background

With the rapid development of urbanization and agriculture in recent years in China, the living standard of people is continuously improved, the requirements on the traditional manufacturing industry are more critical, the shoes are not limited by the appearance and parts of the solidified shoes any more, conceptual shoes such as heelless high-heeled shoes and the like appear, but the practical application is questionable. At present, the sole of shoes on the market is mostly an injection-molded outsole, and then is bonded with a midsole, a waterproof platform and the like, and finally is bonded on the top or is placed with an upper hot sole; the partial shoes are further characterized in that the outer soles and the middle soles are unified, and the upper ironing soles are adhered or placed on the tops of the outer soles; the small part of the shoe is sewed with the sole part in a stitching mode. Through the outer sole of sticky mode bonding, the insole is with scalding the end bonding insecure, drops easily, later to the unusual loaded down with trivial details difficulty of clearance of glue to the technique can appear coming unstuck, opens to glue, and glue overflow scheduling phenomenon influences pleasing to the eye and uses. Some industrial glue smells pungent and affects the health. The sewing thread sewing bottom ironing difficulty is large, the labor cost is high, the periphery of the bottom ironing cannot be perfectly turned, so that a circle of the periphery of the bottom ironing can be tilted, and the sewing thread sewing bottom ironing is not simple and attractive enough.

Disclosure of Invention

In order to solve the technical problems in the prior art, the invention provides a manufacturing process for integrating the whole sole, which removes a great amount of requirements on glue, is simple and beautiful and meets the aesthetic requirements. The specific technical scheme is as follows:

a novel sole manufacturing process comprises the following steps: firstly, covering the whole piece of bottom ironing cloth on a mold, then injecting the raw material of the sole, and performing injection molding to form a sole layer.

Furthermore, functional layers such as an airplane plate, a gasket or a sponge layer and the like are pre-connected with the ironing base cloth and then are covered on the mold.

Further, the sole layer comprises an outsole, or a waterproof platform and the outsole are integrally formed.

Furthermore, the mould is carved with required lines corresponding to the bottom and the side surface of the sole, and the reserved part of the top is used for covering the base fabric.

Further, the sole raw material is fully foamed.

Furthermore, the method also comprises the step of cutting off the redundant ironing base cloth along the periphery of the sole.

Furthermore, the sole raw materials include PU, TPR, TPU and the like.

A sole manufactured by the novel sole manufacturing process.

The invention makes the whole sole be molded at one time in the injection molding stage, eliminates the subsequent step of glue bonding, avoids various problems of degumming, glue failure and the like, and is simpler and more beautiful compared with sewing.

Drawings

Fig. 1 is a schematic view of a first embodiment of the invention for injection molding of the entire sole in one shot.

FIG. 2 is a schematic view of another preferred embodiment of the present invention, which can achieve different effects by adding various cushion layers to the middle layer of the sole.

Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings.

As shown in figure 1, the novel sole manufacturing process of the invention comprises the steps of firstly covering a whole piece of ironing base cloth 1 on a mold, then injecting common sole raw materials such as PU, TPR, TPU and the like, and forming a waterproof platform 2 and an outsole 3 by injection molding, wherein the waterproof platform 2 and the outsole 3 are integrally formed at the moment. The mould is carved with required lines corresponding to the bottom and the side surface of the sole, and the reserved part of the top is used for covering the ironing base cloth 1. When the method is used for manufacturing the sole, the sole raw material needs to be fully foamed, so that the non-ironing base cloth 1 is not contacted with the sole raw material for a short time to cause the separation phenomenon. And then cutting off the redundant ironing base cloth 1 along the periphery of the sole to form the sole whole.

FIG. 2 is another embodiment of the present invention, in which various cushion layers are further added to the middle layer of the sole to achieve different effects. The functional layer 4 such as an airplane plate, a gasket or a sponge layer and the like is pre-connected with the ironing base fabric 1 and then covered on a mold, and the subsequent operation is similar to that of the first embodiment, so that the contact touch feeling between the sole and the ironing base can be adjusted by the method. However, it should be noted that the injection molding time required for different materials is very different, and the amount of the injected raw materials for the sole is very different, and specific material analysis is required.

The hot bottom can be modified in modes of laser carving and the like, the surface of the injection mold can be roughened in one circle of the waterproof table, and the surface of the injection mold can be modified in modes of spraying paint and the like after molding, so that the required effect is achieved.
