Claims (3)

1. Способ литья под давлением подошв для обуви, изготовляемых из расширяющихся и сшиваемых композиций на основе ЭВА, отличающийся тем, что загружают гранулы расширяющейся и сшиваемой композиции на основе ЭВА в форму, оформляющая поверхность которой с одной стороны имеет такой размер, который обеспечивает, чтобы подошва, извлекаемая из формы (1), после спонтанной и полной усадки была несколько меньше по сравнению с номинальными размерами подошвы для данного размера обуви, и с другой стороны имела бы такую форму, чтобы указанная формованная подошва имела по краям выступающий бортик (2) по периметру ее верхней поверхности; помещают шаблон (3), состоящий из тонкой гибкой пластинки, изготовленной из жесткого материала, имеющей профиль, совпадающий с профилем подошвы (1), но такой размер, который соответствует бортику по краю подошвы (2), на верхнюю поверхность подошвы (1), вынимаемой из пресс-формы, и во время ее охлаждения; оставляют указанный шаблон (3) внутри указанного бортика (2) до окончания охлаждения; извлекают шаблон (3) из подошвы после охлаждения.1. The method of injection molding of soles for shoes made from expandable and stitched compositions based on EVA, characterized in that the granules of the expanded and stitched compositions based on EVA are loaded into a mold whose surface on one side is of such a size that ensures that the sole removed from mold (1), after spontaneous and complete shrinkage, was slightly smaller than the nominal sole sizes for a given shoe size, and on the other hand would have such a shape that said molded shoe the sole had a protruding rim at the edges (2) along the perimeter of its upper surface; place the template (3), consisting of a thin flexible plate made of a rigid material having a profile matching the profile of the sole (1), but such a size that corresponds to the edge along the edge of the sole (2), on the upper surface of the sole (1), removed from the mold, and during its cooling; leave the specified template (3) inside the specified rim (2) until the cooling ends; remove the template (3) from the sole after cooling. 2. Способ по п.1, отличающийся тем, что шаблон (3) подвергают небольшому давлению для того, чтобы обеспечить хорошую адгезию к верхней поверхности подошвы (1) внутри расположенного по периметру бортика (2). 2. The method according to claim 1, characterized in that the template (3) is subjected to small pressure in order to ensure good adhesion to the upper surface of the sole (1) inside the perimeter of the rim (2). 3. Литая подошва для обуви, изготовленная из расширяющихся и сшиваемых композиций ЭВА, полученная способом по любому из пп.1-2. 3. Cast sole for shoes made from expandable and stitched EVA compositions obtained by the method according to any one of claims 1 to 2.
