Manufacturing method of an injection molded integral multicolor thermoplastic elastometric foamed sole

A manufacturing method of an injection molded integral multicolor thermoplastic elastomeric foamed sole, wherein the foamed sole is of a shape of an integral sole made from thermoplastic elastomeric foaming bodies of at least two color classifications, and on surfaces of the thermoplastic elastomeric foaming bodies of the at least two color classifications are provided grains of a plurality of arbitrarily superposed injection strips;

• wherein the manufacturing method comprising following steps:
• (S1):
• sending respectively thermoplastic elastomer raw materials of different color classifications, lubricants, and foaming auxiliaries to first milling machines of different color classifications, and milling the same in the first milling machines, forming thermoplastic elastomeric fused masses, in the meantime, adding gas foaming agents into the thermoplastic elastomeric fused masses in the first milling machines, maintain hot mixing and forming polymer-gas dispersoid systems;
• (S2):
• sending polymer-gas dispersoid systems of different color classifications in S1 respectively to second milling machines of corresponding color classifications for cutting, cooling and pressurizing to form thermoplastic elastomeric gas foaming polymers, sending the thermoplastic elastomeric gas foaming polymers to injection molding machines of corresponding color classifications respectively, to have injection nozzles of the injection molding machines to extrude foaming strips of thermoplastic elastomeric gas polymers, and/or have the injection molding machines of at least two color classifications to supply a feeding port of a laminating machine and extrude the foaming strips of thermoplastic elastomeric gas polymers with at least one injection nozzle of the injection molding machines with co-extrusion technology;
• pouring quantitatively and simultaneously or sequentially the foaming strips of thermoplastic elastomeric gas polymers extruded by different injection nozzles of the injection molding machines into a female mold, and form a status of a plurality of arbitrarily superposed layers;
• and when pouring quantitatively into the female mold sequentially, temperature difference between the next foaming strips of the thermoplastic elastomeric gas polymers and last foaming strips of the thermoplastic elastomeric gas polymers shall be ±10° C.;
• and
• (S3):
• after completing pouring of the foaming strips of thermoplastic elastomeric gas polymers of each of the different color classifications, matching the female mold and a male mold, discharge gas therein, and finalize to be the foamed sole.
