Abstract
Es wird die Verwendung einer Spritzgussform (1, 2) zur Herstellung von Spritzgussteilen unterschiedlicher Größe vorgeschlagen. Aus den Spritzgussteilen sollen unkaschierte oder kaschierte Formteile gleicher Größe erhalten werden. Für die Herstellung von nachträglich zu kaschierenden Spritzgussteilen wird ein herausnehmbarer, schalenförmiger Einsatz (7) in die Spritzgussform eingebracht, der in seiner Form der Kaschierung entspricht und den Hohlraum (3) der Spritzgussform um das Volumen der Kaschierung verkleinert.It is proposed to use an injection mold (1, 2) for the production of injection molded parts of different sizes. From the injection molded parts unbacked or laminated moldings of the same size should be obtained. For the production of subsequently to be laminated injection molded parts a removable, bowl-shaped insert (7) is introduced into the injection mold, which corresponds in shape to the lamination and reduces the cavity (3) of the injection mold by the volume of the lamination.
Description
Die Erfindung betrifft ein Verfahren zur Herstellung von kaschierten und unkaschierten Spritzgussteilen unterschiedlicher Größe, die im Hinterspritz- und Hinterspritzprägeverfahren hergestellt werden sowie einen schalenförmigen Einsatz zur Durchführung des Verfahrens.The The invention relates to a process for the production of laminated and unlaminated injection molded parts of different sizes, the be produced in Hinterspritz- and Hinterspritzprägverfahren as well as a bowl-shaped Use for implementation of the procedure.
Kraftfahrzeuginnenteile werden häufig durch Spritzguss hergestellt. Diese Teile werden unkaschiert eingebaut oder sie werden nach ihrer Herstellung und vor dem Einbau mit einer Kaschierung versehen, die eine Schutz- und/oder ästhetische Funktion hat. Auch kann die Kaschierung aus einer Dekorschicht und einer zwischen dieser und dem Spritzgussteil anzuordnenden Schaumschicht bestehen, um die Griffigkeit des Formteils zu verbessern. Insbesondere derartige hinterschäumte Kaschierungen vergrößern das reine Spritzgussteil erheblich. Aus Gründen einer kostengünstigen Fertigung werden sowohl die unkaschierten als auch die unterschiedlich kaschierten Spritzgussteile in identische Fahrzeugteile eingebaut, so dass der jeweils zur Verfügung stehende Einbauraum der gleiche ist. Daher müssen die Spritzgussteile selbst – abhängig davon, ob sie unkaschiert bleiben oder kaschiert werden oder Kaschierungen unterschiedlicher Dicke erhalten – unterschiedlich groß sein. Dies erfordert den Einsatz verschiedener Spritzgussformen mit unterschiedlichem Hohlraum, was sehr kostenaufwendig ist.Automotive interior parts become common produced by injection molding. These parts are installed unbacked or they are after their manufacture and before installation with a Laminated provide that has a protective and / or aesthetic function. Also The lamination can be made of a decorative layer and one between this and the injection molded part to be arranged foam layer to to improve the grip of the molding. In particular, such foam-backed Laminations increase that pure injection molded part considerably. For the sake of a cost-effective Manufacturing will be both the unbacked and the different laminated injection-molded parts installed in identical vehicle parts, so that each available standing installation space is the same. Therefore, the injection molded parts themselves - depending on whether they remain uncovered or laminated or lamination get different thickness - be different sizes. This requires the use of different injection molds with different Cavity, which is very expensive.
So
zeigt beispielsweise die Druckschrift
Es ist daher die Aufgabe der vorliegenden Erfindung, nur eine, einfach ausgeführte Spritzgussform zur kostengünstigen Herstellung von Spritzgussteilen unterschiedlicher Größe zu verwenden, um unkaschierte oder mit einer Kaschierung versehene Formteile gleicher Größe zu erhalten.It is therefore the object of the present invention, only one, simple executed Injection mold for cost-effective Production of injection molded parts of different sizes to use unlaminated or lamination molded parts same To get size.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Verfahren mit den Merkmalen des Anspruchs 1 und durch einen schalenförmigen Einsatz mit den Merkmalen des Anspruchs 2. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.These The object is achieved by a method having the features of claim 1 and by a cupped Use with the features of claim 2. Advantageous developments The invention will become apparent from the dependent claims.
Dadurch, dass für die Herstellung von nachträglich zu kaschierenden Spritzgussteilen ein herausnehmbarer, schalenförmiger Einsatz in die Spritzgussform eingebracht ist, der in seiner Form der Kaschierung entspricht und den Hohlraum der Spritzgussform um das Volumen der Kaschierung verkleinert, besteht die Möglichkeit, mit Hilfe nur einer einzigen Spritzgussform Spritzgussteile unterschiedlicher Größe herzustellen, wobei keine Beschränkung auf nur zwei unterschiedliche Größen besteht, sondern eine beliebige Anzahl unterschiedlicher Größen bei Verwendung jeweils eines entsprechenden Einsatzes gewählt werden kann. So können beispielsweise ein Spritzgussteil, das direkt als unkaschiertes Formteil verwendet wird, ein Spritzgussteil, das für ein einfach kaschiertes Formteil verwendet wird, und ein Spritzgussteil, das für ein Formteil mit hinterschäumter Kaschierung verwendet wird, mittels einer einzigen Spritzgussform und zwei unterschiedlichen Einsätzen hergestellt werden.Thereby, that for the production of subsequently To be laminated injection molded parts a removable, bowl-shaped insert is introduced into the injection mold, in its form of lamination corresponds and the cavity of the injection mold to the volume of Lamination shrinks, it is possible with the help of only one single injection mold to produce injection molded parts of different sizes, with no restriction consists of only two different sizes, but any number of different sizes when used can be selected in each case a corresponding use. For example, a Injection molded part, which is used directly as non-laminated molding is, an injection molded part, for a simply laminated molding is used, and an injection molded part, that for a molded part with foam backing Lamination is used by means of a single injection mold and two different uses getting produced.
Eine vorteilhafte, vielseitige Verwendung der für das Verfahren vorgesehenen Spritzgussform ergibt sich, wenn die Spritzgussform nach Herstellung eines Spritzgussteils für ein mit einer hinterschäumten Kaschierung versehenes Formteil nach Herausnahme des hierfür benutzten Einsatzes für die Fertigung des kaschierten Formteils verwendet wird.A advantageous, versatile use of provided for the process Injection mold results when the injection mold after production of a Injection molded part for one with a foamy one Laminated molding after removal of the used for this purpose Use for the manufacture of the laminated molding is used.
