Abstract:
1. A mold for molding an annular foamed tube for a tire, comprising: a first mold having a first annular concave portion which molds one side, in an axial direction, of the foamed tube for a tire; and a second mold having a second annular concave portion which molds another side, in the axial direction, of the foamed tube for a tire, wherein when the first mold and the second mold are combined in the axial direction, the first annular concave portion and the second annular concave portion form an annular space for molding the foamed tube for a tire, the first mold has first joining faces which are connected to the first annular concave portion and which are positioned at an inner side and an outer side, in a radial direction, of the first annular concave portion, and the first joining faces include horizontal joining faces provided adjacent to the first annular concave portion in a direction orthogonal to the axial direction at the inner side and the outer side, in the radial direction, of the first annular concave portion, and inclined joining faces each provided continuously with a respective one of the horizontal joining faces so as to be inclined with respect to the horizontal joining face at one of an inner side and an outer side in the radial direction, the second mold has second joining faces which are connected to the second annular concave portion and which are positioned at an inner side and an outer side, in the radial direction, of the second annular concave portion, and the second joining faces include horizontal joining faces provided adjacent to the second annular concave portion in a direction orthogonal to the axial direction at the inner side and the outer side, in the radial direction, of the second annular concave portion, and inclined joining faces each provided continuously with a respective one of the horizontal joining faces so as to be inclined with respect to the horizontal joining face at one of an inner side and an outer side in the radial direction, and the first mold and the second mold have configurations which complementarily complete one another via the first joining faces and the second joining faces.
