Abstract
Description
Die vorliegende Erfindung betrifft Verfahren zum Hinterspritzen von Foliendekorteilen und eine durch Anwendung eines solchen Verfahrens herstellbares Fahrzeuginnenausstattungsteil.The The present invention relates to methods of injection molding of Sheets and one by using such a method producible vehicle interior part.
Es ist aus dem Dokument WO 03/33275 A2 bekannt, an der sichtseitigen Oberfläche von Fahrzeuginnenausstattungsteilen einen Zuschnitt einer Dekorfolie zur Verbesserung des Erscheinungsbildes vorzusehen. Es sind zudem Hinterspritzverfahren bekannt zur Herstellung von derartigen Verkleidungsteilen aus Kunststoff mit einem in die Oberfläche eingebetteten Zuschnitt einer Dekorfolie. Hierbei wird der Zuschnitt der Dekorfolie mit seiner späteren Sichtseite auf die Oberfläche der Kavität eines Spritzgießwerkzeugs aufgelegt. Der nachfolgend in die Kavität eingespritzte flüssige und aushärtbare Kunststoff verbindet sich mit der Rückseite des Zuschnitts, wodurch dieser nach dem Aushärten des Kunststoffs auf der Oberfläche des Endprodukts festliegt.It is known from the document WO 03/33275 A2, on the visible side surface of vehicle interior trim parts a blank of a decorative film to improve the appearance. There are also Hinterspritzverfahren known for the production of such trim parts made of plastic with a blank embedded in the surface a decorative foil. Here, the blank of the decorative film with his later Visible side of the surface the cavity an injection mold hung up. The subsequently injected into the cavity liquid and curable Plastic connects to the back of the blank, resulting in this after curing of the plastic on the surface of the final product.
Aufgrund der geringen mechanischen Stabilität des Zuschnitts der Dekorfolie und der hohen Temperatur des verflüssigten Kunststoffmaterials kann es an dessen Rändern des Zuschnitts zu einem Eindringen von Kunststoff zwischen dessen Sichtseite und die Oberfläche des Formwerkzeugs kommen. Außerdem kann der Randbereich des Zuschnitts aufgrund der Erwärmung unerwünscht wellig werden. Dadurch ergeben sich am fertigen Produkt unschöne Randbereich an den Kanten des Zuschnitts.by virtue of the low mechanical stability of the blank of the decorative film and the high temperature of the liquefied plastic material it at its edges the blank to a penetration of plastic between the Visible side and the surface come of the mold. Furthermore the edge area of the blank may become unduly wavy due to heating become. This results in unsightly edge area on the finished product at the edges of the blank.
Die vorliegende Erfindung stellt sich daher die Aufgabe, ein Hinterspritzverfahren anzugeben, durch das sichtseitig einwandfreie Produkte herstellbar sind.The The present invention therefore has as its object an injection molding method specify, by the view side perfect products produced are.
Diese Aufgabe wird gelöst durch ein Hinterspritzverfahren mit den in Anspruch 1 angegebenen Merkmalen. Eine vorteilhafte Ausgestaltung des erfindungsgemäßen Verfahrens ist in Anspruch 2 angegeben.These Task is solved by an injection molding method with the features specified in claim 1. An advantageous embodiment of the method according to the invention is specified in claim 2.
Erfindungsgemäß wird vorgesehen, in dem Hinterspritzverfahren die Werkzeugtrennung und die Abmessungen des Zuschnitts der Dekorfolie derart aufeinander abzustimmen, dass die Trennfuge zwischen Teilen des Formwerkzeugs wenigstens abschnittsweise durch den Zuschnitt abgedeckt wird.According to the invention, it is provided in the back injection process the tool separation and the dimensions the blank of the decorative film to match such that the parting line between parts of the mold at least in sections is covered by the blank.
Vorteilhaft kann ein solches Verfahren zur Herstellung einer im wesentlichen länglichen Zier- oder Dekorleiste für ein Fahrzeuginnenausstattungsteil angewendet werden, wenn die Zier- oder Dekorleiste einen länglichen flachen Abschnitt aufweist, der von dem Zuschnitt der Dekorfolie mit C-förmigem Querschnitt umfasst ist.Advantageous Such a method of producing a substantially elongated Ornamental or decorative strip for a vehicle interior part are used when the ornamental or decorative strip an elongated flat section, that of the blank of the decorative film with C-shaped cross-section is included.
Eine bevorzugte Durchführungsform des erfindungsgemäßen Verfahren wird nachfolgend mit Bezug auf die beigefügten Zeichnungen erläutert. Darin zeigen:A preferred embodiment the method according to the invention is explained below with reference to the accompanying drawings. In this demonstrate:
