An arm (A,B,C) for an elastic doll capable of preventing torsional rotation of a core () in a molding material molded. The elastic doll arm includes the core () made of metal and arranged therein. The metal core () is provided on a distal end thereof or a portion thereof positioned in proximity to the distal end with a spacer () having a sectional area smaller than that of the arm. A material for the spacer () and the molding material for the arm are compatible with each other, resulting in the spacer () being integrated with the molding material.

Arm for elastic doll body, method of forming the arm part, and metal mold for forming the arm part

A molding method and a mold therefor capable of forming a doll head of a shape exactly conforming to a mold by blow molding using a safe molding material. A split mold ( ) which has an inner surface formed to have a configuration conforming to a shape of a doll head ( ) is so arranged that a parting line ( ) formed by mold members ( ) of the split mold may be formed on a hairline of the hair of the doll head ( ) or in proximity thereto. A molding material is constituted by a thermoplastic synthetic resin elastomer as a main ingredient thereof and has a plasticizer and a coloring agent added thereto. The molding material is heated and then dropped in as a parison ( ) between the mold members ( ) of the split mold spaced from each other. Then, the mold members ( ) of the split mold are joined together and air is blown into the split mold. Air is removed through at least one projection such as a nose ( ) or the like from a cavity during blowing of air into the split mold ( ).

Method of molding elastic doll heads and mold therefor

A method for forming a safe molding material into an elastic doll head of a uniform thickness without deteriorating an appearance of the doll head. Split mold members ( ) each have an inner surface ( ) formed to have a configuration which provides a shape of a doll head (A) when the split mold members cooperate with each other. The split mold members ( ) form the doll head with a parting line ( ) in a manner to extend from an upper portion ( ) of a forehead of the doll head through a rear side ( ) of each of ears thereof to a rear portion ( ) of a neck thereof, to thereby substantially equally divide the doll head into two halves. A molding material mainly consisting of a thermoplastic synthetic resin elastomer is heated and dropped in the form of a parison ( ) into a space defined between the split mold members ( ) kept spaced from each other. Then, the split mold members ( ) are joined to each other and air is blown into the thus-joined split mold members. A neck hole ( ) is concurrently formed during the blow molding.
