Description
Gießhaut zur Herstellung von KraftfahrzeuqinnenverkleidunqenCast skin for the production of automotive interior panels aus flexiblem Polyurethanmaterialmade of flexible polyurethane material
Die Erfindung betrifft eine Gießhaut nach dem Oberbegriff des Anspruches.The invention relates to a cast skin according to the preamble of the claim.
Derartige Gießhäute werden verwendet, um die Oberseite von Kraftfahrzeuginnenverkleidungen wie Türverkleidungen, Armaturtafeln und dgl. zu bilden. Die Gießhaut, die auf der sichtbaren Seite vorzugsweise eine Ledernarbung aufweist, wird zur Herstellung der Kraftfahrzeuginnenverkleidung in eine Form eingelegt und durch Hinterschäumung mit einem Spritzgußträger verbunden. Hierbei ist es erforderlich, daß der Raum, in dem das Aufschäumen zwischen Gießhaut und Spritzgußträger stattfindet, abgedichtet wird, d.h. dort, wo Spritzgußträger und Gießhaut aneinanderstoßen muß für eine gute Abdichtung gesorgt werden. Dieses geschieht durch gesonderte Dichtprofile, die in dem Schäumwerkzeug angeordnet sind.Such cast skins are used to form the top of motor vehicle interior panels such as door panels, dashboards and the like. The cast skin, which preferably has a leather grain on the visible side, is placed in a mold to produce the motor vehicle interior panel and is connected to an injection molding carrier by back-foaming. It is necessary for this to seal the space in which the foaming takes place between the cast skin and the injection molding carrier, i.e. where the injection molding carrier and the cast skin meet, a good seal must be ensured. This is done by means of separate sealing profiles that are arranged in the foaming tool.
Der Erfindung liegt nun die Aufgabe zugrunde, eine Gießhaut der eingangs genannten Art zu schaffen, bei der der Einsatz gesonderter Dichtungen zumindest teilweise vermieden wird.The invention is based on the object of creating a cast skin of the type mentioned at the beginning, in which the use of separate seals is at least partially avoided.
Diese Aufgabe wird durch das Kennzeichen des Anspruches gelöst. This task is solved by the characterising feature of the claim.
• ·€·» * 1 &idigr;•·€·» * 1 &idigr;
Erfindungsgemäß wird schon bei Herstellung der Gießhaut, die dann die sichtbare Seite der endgültig hergestellten Kraftfahrzeuginnenverkleidung bildet, bereits ein Dichtprofil angeformt. Hierdurch wird unter Einsatz eines Teils (Gießhaut) des Endproduktes der Herstellungsprozeß vereinfacht und verbessert, da besondere Dichtungen vermieden werden können.According to the invention, a sealing profile is already formed during the production of the cast skin, which then forms the visible side of the final vehicle interior panel. This simplifies and improves the production process by using a part (cast skin) of the end product, since special seals can be avoided.
Im folgenden wird die Erfindung unter Hinweis auf die Zeichnung anhand eines Ausführungsbeispieles näher erläutert.In the following, the invention is explained in more detail using an embodiment example with reference to the drawing.
Es zeigt:It shows:
Fig. 1 einen Querschnitt durch eine Kraftfahrzeuginnenverkleidung mit einer Gießhaut auf der einen Seite; undFig. 1 is a cross-section through a motor vehicle interior panel with a cast skin on one side; and
Fig. 2 eine geschnittene Einzelheit durch eine Gießhaut verbunden mit einem Stützträger.Fig. 2 a sectioned detail connected to a support beam by a casting skin.
In Fig. 1 ist eine Kraftfahrzeuginnenverkleidung im Schnitt dargestellt, die aus einer Gießhaut 3 besteht, die auf ihrer sichtbaren Außenseite vorzugsweise eine Ledernarbung aufweist. Auf der Rückseite befindet sich ein Spritzgußträger 2. Diese beiden Teile, die Gießhaut 3 und der Spritzgußträger 2 sind durch ein Polyurethanschaum 1 miteinander verbunden. An den Rändern der Gießhaut 3 sind Dichtprofile 4 beim Herstellen mit angeschäumt, die den Innenraum, der mit Polyurethanschaum gefüllt wird, abdichten und zwar zwischen der Gießhaut und dem Spritzgußträger.Fig. 1 shows a cross-section of a motor vehicle interior panel, which consists of a cast skin 3, which preferably has a leather grain on its visible outside. On the back there is an injection-molded carrier 2. These two parts, the cast skin 3 and the injection-molded carrier 2, are connected to one another by a polyurethane foam 1. During manufacture, sealing profiles 4 are foamed onto the edges of the cast skin 3, which seal the interior, which is filled with polyurethane foam, between the cast skin and the injection-molded carrier.
In Fig. 2 ist im einzelnen dargestellt, wie das Dichtprofil 4 wirkt und für die Abdichtung gegen den Spritzgußträger 2 sorgt. Bei der Darstellung in Fig. 2 ist noch eine Gießhautauf dickung 5 dargestellt, die der Zentrierung des Spritzgußträgers 2 dient.Fig. 2 shows in detail how the sealing profile 4 works and ensures sealing against the injection molded carrier 2. The illustration in Fig. 2 also shows a casting skin thickening 5 which serves to center the injection molded carrier 2.
Es ist gut erkennbar, daß an der nicht sichtbaren Seite der Gießhaut ein Dichtprofil 4 angeformt ist, das für eine gute Abdichtung des mit Polyurethanschaum 1 ausgeschäumten Innenraumes sorgt. Da die Gießhaut aus flexiblem Material besteht, ist dieses Material auch gut geeignet, um eine Dichtung zu bilden. Die guten Dichteigenschaften dieses Materi-It is clearly visible that a sealing profile 4 is formed on the non-visible side of the cast skin, which ensures good sealing of the interior filled with polyurethane foam 1. Since the cast skin is made of flexible material, this material is also well suited to forming a seal. The good sealing properties of this material
