摘要:
The present invention relates to a method of making parts manufactured by a bi-substance type injection, economically and giving these parts effective and controllable qualities of odor emitters. The method of the invention is characterized in that uses for the first thermoplastic substance forming the skin (31) of part (30), a substance that is permeable to odors and containing filtering means, and for the second thermoplastic substance forming the core (32) of the part surrounded by said skin, a substance that is permeable to odors and including at least one substance (33) emitting odors, whose diffusion is slowed down and controlled by filtering means (34) planned in the skin (31).
摘要:
La présente invention concerne un procédé et un dispositif d'injection du type qui permettent de réaliser des pièces bi-matière ou multimatière relativement économiques pour ce qui est de leur fabrication et répondant aux exigences des utilisateurs. Le dispositif de l'invention comporte des moyens pour injecter simultanément ou séquentiellement dans une empreinte (140) correspondant à une pièce à réaliser au moins une première matière thermoplastique pour constituer une peau extérieure de la pièce et au moins une deuxième matière thermoplastique pour constituer un coeur de la pièce entouré de ladite peau, ces moyens comprenant des buses d'injection distinctes à commande indépendante débouchant dans au moins un canal froid d'alimentation (130) qui est en communication avec ladite empreinte (140), et qui est agencé pour réaliser une injection indirecte desdites matières dans ladite empreinte, des canaux d'injection (110b,120b) entre les buses d'injection et le canal froid d'alimentation (130), ces canaux d'injection étant froids, et un clapet (140) agencé pour arrêter au niveau dudit clapet la matière de peau et laisser passer la matière de coeur, où ledit canal froid d'alimentation (130) est équipé dudit clapet.

摘要:
The invention concerns an injecting method and a device for making bimaterial or multimaterial parts relatively at a relatively low cost and satisfying user requirements. The inventive device is characterized in that it comprises means for simultaneously or sequentially injecting into an impression (14) corresponding to a part (15) to be produced at least one first thermoplastic material to constitute an outer skin (16) of the part and at least one second thermoplastic material to constitute the core (17) of the part enclosed with said skin, said means including injection distinct nozzles (11a, 11b) arranged so as to correspond to distinct regions of the part and opening into at least one cold feeder channel (13) communicating with said impression (14).
