Title
(EN) ELASTOMERIC DOLL HEAD, MOLDING METHOD AND MOLD THEREFOR
(FR) TETE DE POUPEE EN ELASTOMERE, PROCEDE DE MOULAGE ET MOULE POUR CETTE TETE
Abstract
(EN)
A molding method wherein a doll head having elasticity is molded of a safe molding material so that its wall thickness is uniform without impairing its external appearance. A split mold halves (2, 3) form an internal shape (2a, 3a) conforming to the shape of a doll head (A), with a parting line (18) connecting the upper region (27) of the forehead, back sides (28) of the ears and the back side (29) of the head, to substantially bisect the head. A synthetic resin consisting mainly of thermoplastic elastomer is heated and dropped in as a parison (13) between spaced-apart split mold halves (2, 3), whereupon air is blown in after the split mold halves (2, 3) are closed. The neck hole (75) is also formed during the blow molding.
(FR)
L'invention concerne un procédé de moulage consistant à mouler une tête de poupée souple dans un matériau de moulage sans danger, de telle manière que cette tête présente une épaisseur de paroi uniforme sans que cela ne nuise à son aspect externe. Les deux parties (2, 3) d'un moule à coins constituent une cavité (2a, 3a) en forme de tête (A) de poupée, une ligne (18) de séparation passant par la région (27) supérieure du front, les parties (28) situées à l'arrière des oreilles et l'arrière (29) de la tête et divisant la tête en deux parties sensiblement égales. On chauffe une résine synthétique constituée principalement d'élastomère thermoplastique et on la fait tomber sous forme de paraison (13) entre les deux moitiés (2, 3) écartées l'une de l'autre du moule à coin, puis on souffle de l'air dans le moule après avoir fermé les deux moitiés (2, 3) du moule. L'ouverture (75) du cou est également formée au cours de l'opération de soufflage.
