Abstract:
(EN) The invention relates to a method for producing a three-dimensionally shaped trim part (2) of a motor vehicle having a visible side (6) and a mounting side (7), comprising the following steps: - injecting a flowable material with pressure into a chamber (5) of an injection-molding tool that has at least two mold shells (3, 4), which, when assembled, form the chamber (5) with a negative mold of the trim part (2), at least one first of the mold shells (3) forming the visible side (6) and at least one second of the mold shells (4) forming the mounting side (7) of trim part (2), - hardening the material in the chamber (5) and - producing a gas pressure, which acts in a planar manner between the second mold shell (4) and the material during the hardening, - removing the hardened material as the trim part (2) from the chamber (5) of the injection-molding tool.
(FR) L'invention concerne un procédé et un dispositif pour fabriquer un élément d'habillage d'un véhicule à moteur, et l'utilisation du dispositif. L'invention concerne un procédé pour fabriquer un élément d'habillage (2) d'un véhicule à moteur, de forme tridimensionnelle et présentant une face visible (6) et une face de montage (7). Le procédé comprend les étapes consistant : - à pulvériser sous pression un matériau coulant dans une chambre (5) d'un moule à injection, lequel comprend au moins deux moules carapaces (3, 4), lesquels, une fois réunis, forment la chambre (5) présentant un moule négatif de l'élément d'habillage (2), au moins un premier des moules carapaces (3) formant la face visible (6) et au moins un deuxième des moules carapaces (4) formant la face de montage (7) de l'élément d'habillage (2), - à faire durcir le matériau dans la chambre (5) et - à produire une pression de gaz qui agit de façon plane entre le deuxième moule carapace (4) et le matériau pendant le durcissement, - à prélever le matériau durci en tant qu'élément d'habillage (2) de la chambre (5) du moule à injection.
(DE) Verfahren und Vorrichtung zum Herstellen eines Verkleidungsteils eines Kraftfahrzeugs, Verwendung der Vorrichtung Die Erfindung betrifft ein Verfahren zum Herstellen eines eine Sichtseite (6) und eine Montageseite (7) aufweisenden und dreidimensional geformten Verkleidungsteils (2) eines Kraftfahrzeugs, mit folgenden Schritten: - Druckspritzen eines fließfähigen Materials in eine Kammer (5) eines Spritzgusswerkzeugs, das zumindest zwei Formschalen (3,4) aufweist, die zusammengesetzt die Kammer (5) mit einer Negativform des Verkleidungsteils (2) bilden, wobei zumindest eine erste der Formschalen (3) die Sichtseite (6) und zumindest eine zweite der Formschalen (4) die Montageseite (7) des Verkleidungsteils (2) formt, - Aushärten des Materials in der Kammer (5) und - Erzeugen eines Gasdrucks, der flächig zwischen der zweiten Formschale (4) und dem Material während des Aushärtens wirkt, - Entnehmen des ausgehärteten Materials als Verkleidungsteil (2) aus der Kammer (5) des Spritzgusswerkzeugs.
