Problems solved by technology

The quality of the sole will affect the overall quality of the shoe. At present, the soles on the market are generally made of a layer of polyurethane (PU), but the soles made of this type of material will have tiny pores on the surface during molding, and the color difference is large. And non-slip, it is necessary to spray paint on the surface to prevent the above problems, which will not only increase the production cost of the enterprise, but also cause pollution to the environment; and if the soles are all made of thermoplastic polyurethane granules (TPU), the production cost will be greatly increased. It is heavy and not comfortable enough to wear

Embodiment 1

[0020] A method for manufacturing shoe soles, comprising the steps of:

[0021] (1) Forming of the periphery: select gray toner, fully mix the toner with TPU material with a hardness of 65A; put the resulting mixture into the TY8112 plastic injection molding machine provided by Dongguan Taiyu Plastic Machinery Co., Ltd. Heat it in the material tank of the injection molding machine to 130°C, keep the temperature for 25s, and then inject it into the mold of the plastic injection machine to finalize the shape. After cooling, the outer periphery is obtained, and the outer periphery is a cavity;

[0022] (2), the periphery of step (1) gained is put into the mold of the DL330PU type pouring machine provided by Wenzhou Daling Machinery Manufacturing Co., Ltd.;

[0023] (3) Bottom material preparation: put polyethylene adipate (material A) and catalyst into the first material tank of the pouring machine and heat to 40°C. Put the isocyanate (material B) into the second tank of the pou...

Embodiment 2

[0027] (1) Peripheral molding: mix the toner into grass green, fully mix the prepared toner with the TPU material with a hardness of 70A; put the resulting mixture into the TY8112 type provided by Dongguan Taiyu Plastic Machinery Co., Ltd. Heat it in the material tank of the plastic injection machine to 140°C, keep the temperature for 20s, and then inject it into the mold of the plastic injection machine to finalize the shape. After cooling, the outer periphery is obtained, and the outer periphery is a cavity;

[0028] (2), the periphery of step (1) gained is put into the mold of the DL330PU type pouring machine provided by Wenzhou Daling Machinery Manufacturing Co., Ltd.;

[0029] (3) Bottom material preparation: put polyethylene adipate (material A) and catalyst into the first material tank of the pouring machine and heat to 40°C. Put the isocyanate (material B) into the second tank of the pouring machine and heat it to 40°C. Wherein, the mass ratio of polyethylene adipate ...

Embodiment 3

[0033] (1) Forming of the periphery: select red toner, fully mix the toner with TPU material with a hardness of 80A; put the resulting mixture into the TY8112 plastic injection molding machine provided by Dongguan Taiyu Plastic Machinery Co., Ltd. Heating in the material tank of the injection molding machine to 140°C, keeping the temperature constant for 20s, and then injecting it into the mold of the plastic injection machine to finalize the shape. After cooling, the outer periphery is obtained, and the outer periphery is a cavity;

[0034] (2), the periphery of step (1) gained is put into the mold of the DL330PU type pouring machine provided by Wenzhou Daling Machinery Manufacturing Co., Ltd.;

[0035] (3) Bottom material preparation: Put polypropylene adipate (material A) and catalyst into the first material tank of the pouring machine and heat to 45°C. Put the isocyanate (material B) into the second tank of the pouring machine and heat it to 45°C. Wherein, the mass ratio ...

Abstract

A disclosed manufacture method for a shoe sole comprises the following steps: mixing a toner and a TPU material, heating to 130-160 DEG C, keeping a constant temperature for 15 s-25 s, cooling in a mould for shaping to obtain a shoe sole periphery; mixing an A material and a catalyst in a first charging bucket and an B material in a second charging bucket, stirring to obtain a bottom material mixture; pouring the bottom material mixture into the periphery, demoulding and cooling to obtain the shoe sole. The shoe sole is capable of avoiding appearance of pores on the surface of the shoe sole; and the color of the periphery is directly formed and a paint spraying process in a conventional method is avoided, so that cost is saved, pollution to the environment is reduced and the antiskid function of the shoe sole is improved. The bottom of the shoe sole is made of a PU material, so that a user wearing a pair of shoes each with the shoe sole feels enough comfortable. Additionally, the shoe sole is lighter in weight and cost is saved more because of the combined structure of the TPU material periphery and the PU material bottom.

Description

technical field [0001] The invention relates to the field of footwear, in particular to a method for manufacturing shoe soles. Background technique [0002] Shoes are indispensable daily necessities in people's life. With the improvement of the quality of life, people's requirements for shoes also increase. The quality of the sole will affect the overall quality of the shoe. At present, the soles on the market are generally made of a layer of polyurethane (PU), but the soles made of this type of material will have tiny pores on the surface during molding, and the color difference is large. And non-slip, it is necessary to spray paint on the surface to prevent the above problems, which will not only increase the production cost of the enterprise, but also cause pollution to the environment; and if the soles are all made of thermoplastic polyurethane granules (TPU), the production cost will be greatly increased.
