Problems solved by technology

[0002] When manufacturing shoe soles, various materials are often used, such as rubber, EVA, PVC, etc., but no matter what kind of material is used, it is made into a single density or single material sole. If a harder material is used, the sole is too hard and has a bending effect. Not good; if you choose a softer material, although the bending performance is guaranteed, the strength is too low. If you encounter hard stones or sharp objects, you will easily touch the soles of your feet, resulting in poor comfort. If you want to ensure walking safety, you need to increase the sole Thickness, thus causing the weight of the sole to increase, making it quite inconvenient for people to walk due to the heavy sole

Embodiment 1

[0017] Set the rubber and raw rubber raw materials, the hardness of the outer periphery of the outsole is 85°, and the hardness of the middle raw rubber is 75°, and the prepared raw materials and fillers are added to 10,000 horsepower for banburying for 450 seconds; the materials are discharged into blocks To form a semi-finished product, add sulfur, accelerator and color glue to the raw material of the rubber semi-finished product, knead for 350 seconds and place it in a roller machine to press out the sheet, place the rubber base material in the mold for 400 seconds to prepare the outer periphery of the sole; The good rubber bottom material is placed in another mold, and then the raw rubber material is placed in the middle of the rubber bottom material, and it is molded for 300-400 seconds to prepare the sole heart, trimmed, and pasted with a film for storage after printing.

Embodiment 2

[0019] Set the rubber and raw rubber raw materials, the hardness of the outer periphery of the outsole is 80°, and the hardness of the middle raw rubber is 70°. Add the prepared raw materials and fillers into the 10,000 horsepower for banburying for 350 seconds; make the material into a block For the semi-finished product, add sulfur, accelerator and color glue to the semi-finished rubber raw material, knead for 300 seconds, place it in a roller machine to press out the sheet, place the rubber bottom material in the mold for 300 seconds to prepare the periphery of the sole; Place the raw rubber base material in another mold, then place the raw rubber material in the middle of the rubber base material, and mold for 300-400 seconds to prepare the sole heart, trim the edge, and store it with a film after printing.

Embodiment 3

[0021] Set the raw materials of rubber and raw rubber, the outer hardness of the outsole is 90°, and the hardness of the middle raw rubber is 75°. Add the prepared raw materials and fillers to 10,000 horsepower for banburying for 500 seconds; make the material into a block For semi-finished products, add sulfur, accelerator and color glue to the raw materials of rubber semi-finished products, knead for 400 seconds, place them in a roller machine to press out the sheets, place the rubber bottom material in a mold for 450 seconds to prepare the outer periphery of the sole; Place the raw rubber base material in another mold, place the raw rubber material in the middle of the rubber base material, and mold for 400 seconds to prepare the sole peach heart, trim the edge, and store it with a film after printing.

[0022] The performance measurement of the sole of the present invention is carried out at normal temperature under a bending resistance test at a right angle of 90 degrees. ...

Abstract

The invention discloses a pair of soles and a manufacture method thereof. Either sole comprises an outer sole frame made of rubber material and a sole core made of an unvulcanized rubber material and is in a foot shape. The manufacture method of the soles comprises the following steps: firstly, arranging a prepared rubber raw material in a die; heating and cooling to mold; then, arranging the die into another die; and adding and thermally pressing the unvulcanized rubber material to mold. The prepared soles not only have the advantages of high strength, good wear-resisting property, and the like of a hard material, but also have the advantages of good bending property and comfort wearing of a soft material. Compared with soles made of a single material or having a single density, the soles have reduced weight under the condition of the same service life, thereby greatly lightening the walking load.

Description

technical field [0001] The present invention relates to the manufacture of a shoe sole, in particular a dual density shoe sole. Background technique [0002] When manufacturing shoe soles, various materials are often used, such as rubber, EVA, PVC, etc., but no matter what kind of material is used, it is made into a single density or single material sole. If a harder material is used, the sole is too hard and has a bending effect. Not good; if you choose a softer material, although the bending performance is guaranteed, the strength is too low. If you encounter hard stones or sharp objects, you will easily touch the soles of your feet, resulting in poor comfort. If you want to ensure walking safety, you need to increase the sole Thickness, thereby causing the weight of the sole to increase, making it quite inconvenient for people to walk because the sole is too heavy. Contents of the invention [0003] The invention aims to provide a double-density shoe sole with high str...
