Description

Die Erfindung betrifft ein beschichtetes Dekorteil nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a coated decorative part according to the Preamble of claim 1.

Solche Dekorteile sollen insbesondere als Innenverkleidungs­ teile bei Personenkraftwagen eingesetzt werden. Diese Teile müssen in manchen Fällen eine hohe Steifigkeit und Verzugs­ freiheit aufweisen. Eine hohe Verzugsfreiheit ist besonders in Fällen wichtig, in denen derartige Dekorteile mit einem unter Wärme zu trocknenden relativ dicken Klarlacküberzug am fertigen Dekorteil zu versehen sind.Such decorative parts are intended in particular as interior trim parts are used in passenger cars. These parts in some cases have high rigidity and warpage have freedom. A high degree of distortion is special important in cases where such decorative parts with a relatively thick clearcoat to be dried under heat finished decorative part are to be provided.

Derartige Dekorteile sind bisher als Druckgußteile aus Leichtmetall wie beispielsweise Magnesium hergestellt worden. Die Beschichtung erfolgte hierbei jeweils an dem ausgeformten fertigen Druckgußteil.Such decorative parts are so far from die-cast parts Light metal such as magnesium has been produced. The coating was carried out on the molded one finished die casting.

Aus DE 29 44 797 A1 ist es bekannt, Kunststoffteile bei ihrer Herstellung in einer Spritzgußform mit einer Holzfurnierauf­ lage zu versehen. Ein derartiges Teil besitzt keine ausrei­ chende Verzugfreiheit unter Wärme. From DE 29 44 797 A1 it is known to plastic parts in their Manufactured in an injection mold with a wooden veneer able to provide. Such a part has no sufficient freedom from warping under heat.  

Kunststoffgefüllte Metallsandwichteile, bei denen der Kunst­ stoff im Spritzgußverfahren eingebracht wird, sind in DE 24 44 267 A1 beschrieben. Die außenliegenden Metallabdeckungen sind dort nicht beschichtet.Plastic-filled metal sandwich parts, where art Injection molding material are in DE 24th 44 267 A1. The outer metal covers are not coated there.

Hiervon ausgehend beschäftigt sich die Erfindung mit dem Pro­ blem, ein gattungsgemäßes Dekorteil bei einer mit einem Druckgußteil vergleichbaren Festigkeit und Verzugsfreiheit kostengünstig herzustellen. Proceeding from this, the invention deals with the pro blem, a generic decorative part in one with one Die-cast part of comparable strength and freedom from distortion inexpensive to manufacture.  

Eine Lösung hierfür zeigt ein nach den kennzeichnenden Merk­ malen des Patentanspruchs 1 aufgebautes Dekorteil auf.One solution to this is shown by the characterizing note paint the patent claim 1 built on decorative part.

Zweckmäßige Ausgestaltungen sind Gegenstand der Unteransprü­ che 2 bis 7.Appropriate configurations are the subject of the subclaims che 2 to 7.

Ein vorteilhaftes Verfahren zur Herstellung enthält der An­ spruch 8.An advantageous method for the production contains the An saying 8.

Die Erfindung beruht auf dem Gedanken, durch die an sich be­ kannte Sandwichbauweise ein stabiles, gewichtsmäßig leichtes und äußerst verzugfreies Element einfach herstellen zu kön­ nen.The invention is based on the idea by which be in itself knew sandwich construction a stable, light weight and extremely distortion-free element nen.

Die Beschichtung der sichtbaren Metall-Abdeckung kann vor der Herstellung des Sandwichteiles oder auch gleichzeitig mit der Herstellung des Sandwichteiles in einer Spritzgußform erfol­ gen.The coating of the visible metal cover can be in front of the Production of the sandwich part or simultaneously with the Production of the sandwich part in an injection mold gene.

Die räumliche Form des Dekorteiles kann durch vorgeformte Me­ tall-Abdeckungen oder auch durch Ausformen ebener Metallpla­ tinen innerhalb einer Spritzgießform unter dem Spritzgußdruck erzeugt werden.The spatial shape of the decorative part can by preformed Me tall covers or by shaping flat metal plates tinen within an injection mold under the injection molding pressure be generated.

Sandwichbauteile mit Metall-Abdeckungen und eingespritzten die Abdeckungen anbindendem Kunststoff sind an sich zur Her­ stellung von Kunststoffteilen mit reliefartiger Oberfläche bereits aus DE-OS 17 29 168 bekannt. Bei jenen bekannten Tei­ len soll durch die Metall-Abdeckungen jedoch lediglich eine Metalloberfläche auf einem Kunststoffteil erzeugt werden. Bei der Erfindung ist dies dagegen nicht der Fall, da hier viel­ mehr eine nicht metallische sichtbare Außenschicht erzeugt werden soll, die beispielsweise ein aufgebrachtes anschlie­ ßend lackiertes Holzfurnier sein kann.Sandwich components with metal covers and injected the covers connecting the plastic are inherent provision of plastic parts with a relief-like surface  already known from DE-OS 17 29 168. With those known Tei len should only be one due to the metal covers Metal surface can be generated on a plastic part. At the invention, however, is not the case, since there is a lot here creates a non-metallic visible outer layer should be, for example, an applied subsequent lacquered wood veneer.

Soweit es ferner aus DE 41 23 766 C bekannt ist, Dekorteile aus metallbeschichteten Kunststoffteilen zu schaffen, ist auch dies mit der Erfindung gattungsmäßig nicht vergleichbar. Bei den aus dem vorgenannten Dokument bekannten Dekorteilen ist insbesondere auch nur eine Seite metallbeschichtet, wäh­ rend die andere gegenüberliegende Seite aus dem Kunststoff des Grundteiles gebildet wird. An das Kunststoffteil dort an­ geformte Funktionsteile durchragen auch keine Metall- Abdeckung wie bei der vorliegenden Erfindung.As far as it is also known from DE 41 23 766 C, decorative parts to create from metal-coated plastic parts this also cannot be compared generically with the invention. In the decorative parts known from the aforementioned document In particular, only one side is metal-coated, weh rend the other opposite side from the plastic of the base part is formed. At the plastic part there shaped functional parts do not protrude through metal Coverage as in the present invention.

Ein Ausführungsbeispiel der Erfindung mit Bezug auf das zu schaffende Dekorteil als solches sowie mit Bezug auf das an­ zuwendende Spritzgußverfahren sind in der Zeichnung darge­ stellt und werden nachfolgend näher beschrieben.An embodiment of the invention with reference to the creative decorative part as such and with reference to that Injection molding processes are shown in the drawing represents and are described in more detail below.

Fig. 2 einen Schnitt durch eine Spritzgießeinrichtung mit einliegendem Sandwich-Dekorteil. Fig. 2 shows a section through an injection molding device with an inserted sandwich decorative part.

Das als Sandwichplatte aufgebaute Dekorteil 1 nach Fig. 1 be­ steht aus einer oberen metallischen Abdeckung 2 und einer un­ teren metallischen Abdeckung 3, wobei diese beiden Abdeckun­ gen über eine Kunststoffüllung 4 miteinander verbunden sind.The decorative part 1 constructed as a sandwich panel according to FIG. 1 be consists of an upper metallic cover 2 and a lower metallic cover 3 , these two covers being connected to one another via a plastic filling 4 .

Auf der oberen Abdeckung 2 aufkaschiert ist ein Edelholzfur­ nier 5, das mit einem Klarlacküberzug 6 überzogen ist.Laminated on the top cover 2 is a Edelholzfur nier 5 , which is coated with a clear coat 6 .

Zur Verbesserung der Haftung des Kunststoffes 4 an den Abdec­ kungen 2 und 3 sind dort sogenannte Kopplungsschichten 7 aus beispielsweise aufgeklebtem Vlies vorgesehen.To improve the adhesion of the plastic 4 to the coverings 2 and 3 , so-called coupling layers 7 made of, for example, bonded nonwoven are provided there.

Durch die untere Abdeckung 3 ragt als ein von dem Kunststoff 4 ausgehendes und gebildetes Funktionselement 8 heraus.The lower cover 3 protrudes as a functional element 8 that starts and is formed from the plastic 4 .

Hergestellt wird das Dekorteil 1 in einer Kunststoff- Spritzgießeinrichtung nach Fig. 2. Dort sind die beiden Form­ hälften der Spritzgießeinrichtung angedeutet, zwischen denen der Formraum zur Aufnahme und Ausbildung des Dekorteiles 1 ausgebildet ist.The decorative part 1 is produced in a plastic injection molding device according to FIG. 2. There, the two mold halves of the injection molding device are indicated, between which the molding space is designed to receive and form the decorative part 1 .

Der unter Druck einzuspritzende Kunststoff gelangt über das Angießsystem 9 in das Innere des Formhohlraumes der Spritz­ gießeinrichtung. In den beiden Formhälften ist jeweils die dem fertigen Dekorteil 1 entsprechende Außenform eingeformt. Die obere Abdeckung 2 ist bereits mit einem Holzfurnier, das die Sichtseite des Dekorteiles darstellen soll, versehen. Die Holzfurnierschicht ist in der Fig. 2 bei der oberen Abdeckung 2 nicht erkennbar gezeichnet. In der unteren Formhälfte kön­ nen Schieber 10 angebracht sein, um in Ausformrichtung hin­ terschnittartige Funktionsteile 8 durch die untere Abdeckung 3 hindurch ausformen zu können.The plastic to be injected under pressure passes through the sprue system 9 into the interior of the mold cavity of the injection molding device. The outer shape corresponding to the finished decorative part 1 is molded in each of the two mold halves. The top cover 2 is already provided with a wood veneer, which is to represent the visible side of the decorative part. The wood veneer layer is not recognizably drawn in FIG. 2 for the top cover 2 . In the lower mold half NEN slider 10 can be attached in order to be able to form terschnitt-like functional parts 8 through the lower cover 3 through.

Um bei in der Form vorgeformten Abdeckungen 2 und 3 in dem Formhohlraum den gegenseitigen Abstand einstellen zu können, können aus der unteren Schicht Abstandshalter 11 ausgestanzt sein. Die beiden Abdeckungen bestehen jeweils aus Aluminium. Der gegenseitige Abstand zwischen den beiden Abdeckungen 2 und 3 kann auch durch in der unteren Formhälfte angebrachte Distanzbolzen 12 erzielt werden.In order to be able to set the mutual distance in the mold cavity with covers 2 and 3 preformed in the mold, spacers 11 can be punched out of the lower layer. The two covers are made of aluminum. The mutual distance between the two covers 2 and 3 can also be achieved by spacer bolts 12 attached in the lower mold half.

Um eine Verankerung der unteren Abdeckung 3 gegenüber dem eingespritzten Kunststoff 4 zu verbessern, können aus dieser Abdeckung Laschen 13 nach innen ausgestanzt sein, die von dem eingespritzten Kunststoff 4 formschlüssig umfaßt werden.In order to improve the anchoring of the lower cover 3 with respect to the injected plastic 4 , tabs 13 can be punched out of this cover, which are positively encompassed by the injected plastic 4 .

Um in der oberen Formhälfte die obere Abdeckung 2 lagefixiert halten zu können, kann dort ein Vakuumanschluß 14 vorgesehen sein. Durch ein dort anstehendes Vakuum wird die obere Abdec­ kung 2 an die obere Formhälfte angezogen, wozu mehrere über die obere Formhälfte verteilte Vakuumanschlüsse angebracht sein können.In order to be able to hold the upper cover 2 fixed in position in the upper mold half, a vacuum connection 14 can be provided there. By a vacuum present there, the upper cover 2 is attracted to the upper mold half, for which purpose several vacuum connections distributed over the upper mold half can be attached.

Bei dem in Fig. 2 dargestellten Beispiel werden die obere und die untere Abdeckung 2, 3 jeweils vorgeformt in den Formhohl­ raum zum Befüllen mit einzuspritzendem Kunststoff eingelegt. Dabei ist die obere Abdeckung 2 beim Einlegen bereits mit ei­ nem Edelholzfurnier 5 kaschiert. Bei einem insgesamt weniger räumlich ausgeformten Dekorteil 1 können die Abdeckungen 2 und 3 auch als flache unverformte Platinen eingelegt werden. Durch den unter Druck eingespritzten Kunststoff 4 werden sie dann an die Innenform des Formhohlraumes angepreßt und nehmen deren Gestalt an. Hierdurch entfällt ein getrennter vorausge­ hender Vorformvorgang für die Abdeckungen 2 und 3. Die obere Abdeckung 2 kann dabei bereits mit einer Dekorschicht wie beispielsweise einem Edelholzfurnier 5 kaschiert dein. Mög­ lich ist es aber auch, das Kaschieren mit der Dekorschicht erst in der Form der Spritzgießeinrichtung vorzunehmen. Denn der Druck des einzuspritzenden Kunststoffes 4 reicht sowohl für eine Verformung der Abdeckungen 2, 3 sowie für ein Aufka­ schieren einer Dekorschicht aus. Dabei spielt insbesondere die durch den heiß eingespritzten Kunststoff 4 hohe auf die Abdeckungen 2 und 3 einwirkende und sich übertragende Tempe­ ratur eine bedeutende Verformungs- und Kaschierhilfe.In the example shown in Fig. 2, the upper and lower covers 2 , 3 are each preformed in the mold cavity for filling with plastic to be injected. The upper cover 2 is already laminated with egg nem wood veneer 5 when inserted. In the case of an overall less decorative part 1 , the covers 2 and 3 can also be inserted as flat undeformed boards. Due to the plastic 4 injected under pressure, they are then pressed against the inner shape of the mold cavity and take on their shape. This eliminates the need for a separate preforming operation for covers 2 and 3 . The upper cover 2 can already be laminated with a decorative layer such as a fine wood veneer 5 . However, it is also possible to carry out the lamination with the decorative layer only in the form of the injection molding device. This is because the pressure of the plastic 4 to be injected is sufficient both for a deformation of the covers 2 , 3 and for a Aufka sheer of a decorative layer. In particular, the hot injected plastic 4 plays high on the covers 2 and 3 and is transferring temperature used as a significant deformation and lamination aid.

In dem in Fig. 2 gezeigten Beispiel ist das Angußsystem 9 an der die Sichtseite darstellenden oberen Abdeckung 2 ange­ bracht. Dies ist immer dann möglich, wenn an der betreffenden Stelle an dem fertigen Dekorteil 1 eine Ausnehmung oder abzu­ deckende Stelle vorhanden ist. Anderenfalls muß der Anguß von der Seite oder über die untere Abdeckung 3 erfolgen.In the example shown in Fig. 2, the sprue system 9 is introduced to the top cover 2 which is the visible side. This is always possible if there is a recess or location to be covered at the relevant location on the finished decorative part 1 . Otherwise the sprue must be made from the side or via the lower cover 3 .
