Problems solved by technology

[0009] The problem with the prior art is that the midsole produced by the prior art is made of two pieces of cardboard and the iron core in the middle. Also lower; and through the existing production method of hand-made midsole, manual cutting is required, and then the edges need to be smoothed, so that defective products are prone to appear in the process of cutting and grinding, and the production efficiency is low

Embodiment 1

[0043] according to figure 1 Shown, the molding method of midsole, this method comprises the following steps:

[0044] 101. Prepare a shoe mold, lay emery cloth in the shoe mold, and the shape of the emery cloth is the same as the shape of the inner bottom surface of the mould;

[0045] 102. Heating the raw material polypropylene to 180-250 degrees to melt it;

[0046] 103. Put the melted raw material polypropylene in 8×10 3 KPa-12×10 3 Inject into the shoe mold under the injection pressure of KPa;

[0047] 104. In 8×10 3 KPa-12×10 3 Under the holding pressure of KPa, carry out 25-35 seconds holding pressure setting;

[0048] 105. Cool for 55-65 seconds after holding the pressure and shaping, then open the mold.

[0049]Compared with the prior art, in this molding method, the inner bottom surface of the mold refers to the projection on the horizontal plane, which is the same surface as the projection of the horizontal plane of the midsole. In the temperature range of 1...

Embodiment 2

[0053] Such as figure 2 Shown, the molding method of midsole, this method comprises the following steps:

[0054] 201. Prepare a shoe mold, lay emery cloth in the shoe mold, and the shape of the emery cloth is the same as the shape of the inner bottom surface of the mould;

[0055] 202. Heating the raw material polypropylene to 200-240 degrees to melt it;

[0056] 203. Put the melted raw material polypropylene in 9×10 3 KPa-11×10 3 Inject into the shoe mold under the injection pressure of KPa;

[0057] 204. In 9×10 3 KPa-11×10 3 Under the holding pressure of KPa, carry out 25-35 seconds holding pressure setting;

[0058] 205. Cool for 55-65 seconds after holding the pressure and setting the mold, then open the mold.

[0059] Wherein, the melting temperature of the raw material polypropylene may also be 200-240 degrees. The melting temperature is between 200°C and 240°C. Within this temperature range, polypropylene can be fully and well melted, the density distribution...

Embodiment 3

[0067] Such as image 3 Shown, the molding method of midsole, this method comprises the following steps:

[0068] 301. Prepare a shoe mold, lay emery cloth, cardboard and iron core in the shoe mold, the shape of the emery cloth is the same as that of the cardboard, and the shape of the inner bottom surface of the mold is the same; The iron core and the cardboard layer are arranged between the polypropylene layer and the emery cloth layer, the iron core is connected to the polypropylene layer, the cardboard layer is connected to the emery cloth layer, and the The edges of the emery cloth layer wrap the edges of the iron core and the cardboard;

[0069] 302. heating the raw material polypropylene to 200-240 degrees to melt it;

[0070] 303. The raw material polypropylene after melting is in 9×10 3 KPa-11×10 3 Inject into the shoe mold under the injection pressure of KPa;

[0071] 304. In 9×10 3 KPa-11×10 3 Under the holding pressure of KPa, carry out 25-35 seconds holding...

Abstract

The invention relates to the technical field of production of shoes, and particularly relates to an insole and a forming method thereof. The insole comprises a polypropylene layer and an abrasive cloth layer, wherein the polypropylene layer and the abrasive cloth layer are connected. The forming method of the insole comprises the steps of preparing a shoe-shaped mould, and laying the abrasive cloth in the shoe-shaped mould; heating a raw material, polypropylene, from 180 degrees to 250 degrees for fusing the polypropylene; injecting the fused polypropylene into the shoe-shaped mould under the injection pressure of 8*103KPa-12*103KPa; carrying out pressure maintaining formation on the polypropylene under the maintaining pressure of 8*103KPa-12*103KPa for 25-35 seconds; and cooling for 55-65 seconds to open the mould after the pressure maintaining formation. The insole provided by the invention has the advantages of being high in use intensity and being unlikely to come unglued. The method is used for automatically molding and has the advantages that the production efficiency is improved, and the cost is saved.

Description

technical field [0001] The invention relates to the production field of shoes, in particular to a midsole and a molding method of the midsole. Background technique [0002] The sole is divided into a sole directly in contact with the ground, a midsole adhered to the sole, and an adhesive layer adhered to the upper, and the adhesive layer is adhered to the midsole. The midsole is therefore an integral part of the sole in the middle layer of the sole. The rationality of the midsole is that the appearance quality of the shoe is clear and beautiful, while the inner quality is not easy to deform and comfortable to wear, especially in the production of a compact shoe last. [0003] The traditional midsole molding method is mainly made by hand, and the specific steps include: [0004] Using two pieces of cardboard, brush glue on one side of the two pieces of cardboard respectively; [0005] The faces of the two pieces of cardboard brushed with glue are opposite, and an iron plat...
