Problems solved by technology

But its shortcoming is, the insole that this method makes, after the insole is placed on the sole surface, when the people walks on the insole, the insole is easy to slide due to the transformation of the sole of the foot, which makes walking very inconvenient and uncomfortable. Therefore, the method still needs to be improved

Abstract

The invention discloses a shoe pad and a making method of the shoe pad. The shoe pad is characterized in that the shoe pad is composed of an ingredient a and an ingredient b, wherein the mixing ratio of the ingredient a to the ingredient b is 1:3-2:4. The making method of the shoe pad sequentially comprises the following steps of: 1. raw material and additive: selecting shoe pad surface layer cloth as the raw material and preparing the additive capable of being prepared to polyurethane after being mixed; 2. opening a mould, paving the shoe pad surface layer cloth on the inner surface a lower mould body, and closing the mould; 3. mixing the ingredient a with the ingredient b, and injecting the mixed material in the mould through a mould injection opening; and 4. opening the mould, taking out the shoe pad, moving the shoe pad to the lower mould of an edge trimmer, and pressing the upper mould of the edge trimmer downwards to obtain the finished product. The shoe pad disclosed by the invention has the advantages of eliminating the problem that the shoe pad is easy to slide due to the change of sole application point during the walking process of a person.

Description

Technical field [0001] The invention relates to the technical field of manufacturing shoe holders, in particular to a polyurethane insole and a manufacturing method thereof. Background technique [0002] An existing Chinese invention patent entitled "Method for Manufacturing Breathable Insoles" with the application number CN200510008635.7 proposes a method for making insoles. This method injects a foaming material into a cavity of a bottom mold, and then puts a The first top mold closes the mold cavity and heats it to trigger the foaming material to bridge and foam in the mold cavity to form a polyurethane / polyurethane body, and then the polyurethane / polyurethane body is not yet cooled Next, open the first top mold, and then use a second top mold to close the mold cavity, so that a fiber material and an adhesive material set on the second top mold are put into the mold cavity together, and the second top mold is controlled. The mold is heated at a temperature not lower than the ...
