Abstract

L'invention porte sur un outil de moulage. Au moment du moulage par injection d'une première résine, un trajet d'écoulement de pénétration (18) est formé au niveau du côté arrière d'une première partie (11) par une tige de trajet d'écoulement (14). Au moment du démoulage, la tige de trajet d'écoulement (14) est déplacée dans une direction qui coupe la direction d'ouverture/fermeture de l'outil pour enlever la tige. Une deuxième résine est introduite dans une deuxième partie (12) à l'aide d'un deuxième outil femelle. La deuxième résine est introduite dans la partie (deuxième partie (12)) qui est entourée par la première partie (11), en suivant le trajet d'écoulement de pénétration (18). De cette façon, la deuxième résine est introduite dans une partie fermée d'une figure fine ou d'un petit caractère, à travers le trajet d'écoulement de pénétration (18).
