Пресс-форма используется в порошковой металлургии для прессования изделий, имеющих наружную цилиндрическую поверхность. Изобретение способствует повышению качества за счет уменьшения овальности цилиндрической части изделий. Сущность изобретения: обойма сопряжена с направляющими по конической поверхности, что исключает появление зазора между наружной поверхностью обоймы и внутренней поверхностью направляющих, при этом обойма с матрицей имеют возможность осевого перемещения относительно направляющих, для чего в исходном состоянии между нижним торцом обоймы и внутренним торцом направляющих имеется зазор, а наружная поверхность обоймы выполнена с участками переменной конусности.The mold is used in powder metallurgy for pressing products having an outer cylindrical surface. The invention contributes to the quality by reducing the ovality of the cylindrical part of the products. The inventive holder is connected with guides on a conical surface, which eliminates the appearance of a gap between the outer surface of the yoke and the inner surface of the guides, while the yoke with the matrix can axially move relative to the guides, for which there is the gap, and the outer surface of the cage is made with areas of variable taper.
