Abstract
(EN)
Provided are an injection mold and an injection molding method by which a boundary line between a first material and a second material curved so as to be sharply bent like a round chamfered shape can be formed reliably in a desired position, and a molded article molded using the injection mold and the injection molding method. The sum of a length w of an inclined-part forming part 51a and a length y of a thinned-part forming part 51b in a width direction of a linear part or a width direction of a curved part is at least equal to a prescribed value, and the thinned-part forming part 51b forming the curved part has a second length y longer than a first length in the width direction of the curved part.

La présente invention décrit un moule d’injection et un procédé de moulage par injection dans lequel une ligne de délimitation entre un premier matériau et un second matériau incurvé afin d’être fléchi de sorte qu’une forme à chanfrein ronde puisse être formée de manière fiable dans une position souhaitée, et un article moulé qui est moulé en utilisant le moule d’injection et le procédé de moulage par injection. La somme d’une longueur (w) d’une pièce formant partie inclinée (51a) et d'une longueur y d’une pièce formant partie amincie (51b) dans un sens de la largeur d’une partie linéaire ou un sens de la largeur d’une partie incurvée est au moins égale à une valeur prescrite, et la pièce de formation de pièce amincie (51b) formant la partie incurvée présente une seconde longueur y supérieure à une première longueur dans le sens de la largeur de la partie incurvée.
