Problems solved by technology

First of all, the selected fabrics must be high temperature resistant, and the cost is relatively high; secondly, some fabrics with special requirements such as deep and light textures on the surface or laser effects will lose their original textures or color effects after high temperature and high pressure Moreover, this high-temperature and high-pressure shaping process cannot wrap the fabric on the side of the 3D pattern on the upper, and lacks integrity, making it unable to meet certain specific requirements; finally, the three-dimensional part of this high-temperature, high-pressure shaping The elasticity is soft, and its hardness cannot be adjusted

[0034] A method for making an elastic shoe material, comprising the steps of:

[0035] Step 1: Prepare a hard plate, which can be a metal plate;

[0036] Step 2: Make the concave mold: apply the designed 3D pattern on the upper, carve the concave mold of the pattern on the hard plate, and set a number of vacuum holes inside the concave mold;

[0037] Step 3: Use an airtight leather, cloth, or rubber roll as the surface material, and cut it into a sheet slightly larger than the size of the die pattern;

[0038] Step 4: Make a cover based on the outer dimensions of the die, and the die and cover are connected by hinges and mold locks, or screws and nuts; install a vacuum box at the bottom of the die;

[0039] Step 5: Place the cut face material face down on the die;

[0040] Step 6: Turn on the vacuum pump. Through the suction of the vacuum pump, the air between the surface material and the die is sucked away to make it fit the die;

[0041] Step 7: Stir and mix polyether po...

Abstract

The invention discloses a making method of an elastic shoe material. The making method comprises the following steps: preparing a hard plate; in accordance with a designed 3D pattern which is appliedto a vamp, carving a concave die of the pattern on the hard plate, and arranging a plurality of vacuum holes in the inner side of the concave die; cutting an airtight leather, cloth or rubber coiled material, which serves as a surface material, into a sheet which is slightly greater than the size of the pattern of the concave die; making a cover in accordance with the overall dimensions of the concave die, and connecting the concave die and the cover by virtue of a hinge and a die lock or by a screw and a nut; arranging a vacuum box at the bottom of the concave die; placing the surface material, which is obtained from cutting, on the concave die in a mode of keeping the front side of the surface material facing downwards; turning on a vacuum pump, wherein air between the surface material and the concave die is sucked away through suction force of the vacuum pump, so that the surface material clings to the concave die; stirring and mixing polyether polyol and isocyanate according to certain proportions, and filling the back side of the surface material in the concave die with an obtained mixture; covering the concave die with the cover, locking the concave die with the die lock or tightening the concave die with the screw and nut; and after 5-10min, releasing the die lock or the screw and nut, taking out the concave die, and conducting trimming, so that the elastic shoe materialis obtained.

Description

【Technical field】 [0001] The invention belongs to the technical field of making shoe materials, shoe soles and insoles, and specifically refers to a method for making elastic shoe materials. 【Background technique】 [0002] Most of the vamps with 3D patterns appearing on the market are shaped by high temperature and high pressure. First of all, the selected fabrics must be high temperature resistant, and the cost is relatively high; secondly, some fabrics with special requirements such as deep and light textures on the surface or laser effects will lose their original textures or color effects after high temperature and high pressure Moreover, this high-temperature and high-pressure shaping process cannot wrap the fabric on the side of the 3D pattern on the upper, and lacks integrity, making it unable to meet certain specific requirements; finally, the three-dimensional part of this high-temperature, high-pressure shaping The elasticity is soft, and its hardness cannot be ad...
