Abstract:
A molding method of a sand mold including a hardened layer in a predetermined thickness range from an outer layer part, includes: forming a cavity and a filling opening of a die so that a dimension, which is a largest dimension between two intersections of straight lines passing through a section of a boundary portion between the cavity and the filling opening of the die, with respect to an outside line of the section, is less than a predetermined ratio with respect to a thickness dimension of that part of a product portion of the sand mold from which a blowing opening molded in the filling opening projects, the product portion being formed by the cavity of the die; and filling foamed sand into the cavity from the filling opening of the die.

Claim (Index 1):
A molding die for molding a sand mold including a hardened layer in a predetermined thickness range from an outer layer part, the molding die comprising:\n a cavity; and a filling opening communicating with the cavity and configured to fill the foamed sand into the cavity, wherein:\n the cavity and the filling opening are configured such that a dimension b, which is a largest dimension between two intersections of straight lines passing through a section of a boundary portion between the cavity and the filling opening, with respect to an outside line of the section, is less than a predetermined ratio with respect to a thickness dimension d of a part of a product portion of the sand mold from which a blowing opening molded in the filling opening projects, the product portion being formed by the cavity of the die, and \n a thickness of a vulnerable portion or hollow portion is generally \u2153b with respect to the whole thickness b of the blowing opening, a thickness of the hardened layer covering the vulnerable portion or hollow portion is generally \u2153b, a thickness of the hardened layer of the product portion is generally \u2153d, and a sum \u2154b of the thickness \u2153b of the vulnerable portion or hollow portion of the blowing opening and the thickness \u2153b of the hardened layer is less than a thickness \u2153d of the hardened layer of a part of the product portion in which the blowing opening is formed.
