Description

Die Erfindung betrifft ein Verfahren und ein Formwerkzeug zum Herstellen von Formteilen, insbesondere für die KFZ-Innenverkleidung, bestehend aus einer mehrfarbig lackierten Gießhaut, einem Tfägerteil und einer dazwischen liegenden Schammschicht.The The invention relates to a method and a mold for manufacturing of molded parts, especially for the car interior trim, consisting of a multicolored cast skin, a T-part and a layer of pebble in between.

An die Fahrzeuginnenverkleidungen, die aus einer sichtbaren Gießhaut einer sogenannten Dekorfolie, einem versteifenden Trägerteil und einer dazwischen liegenden Schaumschicht bestehen, werden immer höhere Anforderungen gestellt. Dieses gilt insbesondere hinsichtlich einer Mehrfarbenlackierung der Gießhaut auf der sichtbaren Seite. Es ist schwierig, die einzelnen Farben bei einer Mehrfachlackierung sauber und genau voneinander zu trennen.On the vehicle interior panels, which are made of a visible cast skin so-called decorative film, a stiffening carrier part and one in between lying foam layer, increasing demands are made. This applies in particular to multi-color painting cast skin on the visible side. It is difficult to see the individual colors separate cleanly and precisely from each other in case of multiple painting.

Die Gießhaut wird grundsätzlich in einem ersten Formwerkzeug hergestellt, in das zuerst der Lack eingebracht wird, auf den dann das Polyurethanmaterial für die Gießhaut rückseitig eingegossen wird. Nach dem Farbeintrag wird das Schäumwerkzeug verschlossen. Diese Gießhaut wird dann zur weiteren Verarbeitung, d.h. zur Herstellung der eigentlichen Innenverkleidung in ein zweites Formwerkzeug eingelegt.The cast skin basically produced in a first mold, in which the paint is first is introduced, on which then the polyurethane material for the casting skin on the back is poured. After the color entry, the foaming tool locked. This cast skin is then used for further processing, i.e. to make the actual Inner lining inserted in a second mold.

Im Stand der Technik sind bereits Verfahren zur Herstellung von Innenverkleidungsteilen für Fahrzeuge bekannt. So beschreibt EP 275 389 A2 ein Innenverkleidungsteil mit Dekormaterialien, das aus einem aus flüssigem Reaktionsharzgemisch und Glasfasern angeschäumten Träger besteht, bei dem sichtseitig unterschiedlich kaschierte Abschnitte dargestellt sind.Methods for the production of interior trim parts for vehicles are already known in the prior art. So describes EP 275 389 A2 an interior trim part with decorative materials, which consists of a carrier foamed from a liquid reaction resin mixture and glass fibers, in which differently laminated sections are shown on the visible side.

Weiterhin beschreibt EP 526 818 A2 ein Verfahren zur Herstellung von Polymerisatformstücken aus Gießharzen mit farblich differenzierten Oberflächenbereichen bei dem eine Oberfläche des formgebenden Werkzeugs vor dem Verfüllen mit dem Gießharz einer farbmittelhaltigen Zusammensetzung derart beschichtet wird, dass eine farbliche Differenzierung entsteht.Furthermore describes EP 526 818 A2 a process for the production of polymer moldings from casting resins with color-differentiated surface areas in which a surface of the shaping tool is coated before the filling with the casting resin of a colorant-containing composition such that a color differentiation arises.

Ferner ist eine Instrumententafel, aufgebaut aus einer Schale aus einem flexiblen plastischen Material, in US 5,439,630 A offenbart. Schließlich beschreibt WO 98/31524 A1 ein Verfahren zur Herstellung von Innenverkleidungsteilen für Fahrzeuge, wobei in einem ersten Schritt eine Vinylfolie in ein Vakuumformwerkzeug eingelegt wird.Furthermore, an instrument panel, made up of a shell made of a flexible plastic material, is in US 5,439,630 A disclosed. Finally, WO 98/31524 A1 describes a method for producing interior trim parts for vehicles, a vinyl film being placed in a vacuum molding tool in a first step.

Der Erfindung liegt nun die Aufgabe zugrunde, ein Verfahren und entsprechende Formwerkzeuge zu schaffen, durch die eine optisch saubere Trennung der einzelnen Farbbereiche auf der sichtbaren Seite der Gießhaut möglich ist.The The invention is based on the object of a method and corresponding To create molds by which an optically clean separation of the individual color areas on the visible side of the casting skin is possible.

Diese Aufgabe wird grundsätzlich durch die Verfahrensschritte nach Anspruch 1 gelöst.This Task basically solved by the method steps according to claim 1.

Erfindungsgemäß erfolgt das Herstellen des Formteiles ebenso wie bei bekannten Verfahren in zwei unterschiedlichen Formwerkzeugen. In dem ersten Formwerkzeug wird die Gießhaut hergestellt. In dem Formwerkzeug ist ein Farbtrennvorsprung vorgesehen, der die Bereiche, die mit unterschiedlichen Farben lackiert werden sollen, voneinander trennt. Der eine Bereich wird durch eine Abdeckmaske abgedeckt, so daß zuerst der erste Bereich mit der einen Farbe und dann der zweite Bereich mit der anderen Farbe nach Entfernen der Abdeckmaske lackiert wird. Bei der zweiten Lackierung ist ein Oberspray unschädlich. Durch den Farbtrennvorsprung entsteht in der Gießhaut eine die Farbbereiche voneinander trennende Nut. Die auf diese Weise hergestellte Gießhaut wird dann in das zweite Formwerkzeug eingelegt. In diesem befindet sich ein dünnes Trennblech, das in der die Farben trennenden Nut liegt. Durch Anlegen von Vakuum wird die Gießhaut in diesem Bereich der Nut fixiert, d.h. dicht an das Trennblech angesaugt. Hierdurch wird die Nut so schmal oder dünn, daß sie in dem fertigen Produkt als saubere Trennnaht in Erscheinung tritt. Die unmittelbare Grenze zwischen den beiden Farben liegt am Boden der Nut und ist nicht sichtbar. Sichtbar ist eine schmale Nut, die wie eine Schattenfuge wirkt.According to the invention the production of the molded part as well as in known processes in two different molds. In the first mold becomes the casting skin manufactured. A color separation projection is provided in the mold, of the areas that are painted with different colors should separate from each other. One area is covered by a mask covered so that first the first area with one color and then the second area is painted with the other color after removing the mask. With the second coat of paint, an upper spray is harmless. By The color separation projection is created in the cast skin in the color areas separating groove. The cast skin produced in this way is then placed in the second mold. In this is a thin divider, that lies in the groove separating the colors. By applying vacuum the cast skin is in fixed in this area of the groove, i.e. sucked close to the divider. This makes the groove so narrow or thin that it is in the finished product clean separation seam appears. The immediate limit between the two colors lies on the bottom of the groove and is not visible. A narrow groove is visible, like a shadow gap acts.

In den Ansprüchen 2 und 3 sind besondere Ausgestaltungen der beiden Formwerkzeuge unter Schutz gestellt, die insbesondere auf die Ausbildung der die Farben trennende Nut durch den Farbtrennvorsprung und das Trennblech gerichtet sind, an das die Gießhaut im Bereich der Nut angesaugt wird, um hier eine schmale oder dünne "Naht" zu erzeugen.In the claims 2 and 3 are special configurations of the two molding tools under protection, in particular on the training of the Color separating groove through the color separation tab and the divider are directed to the cast skin is sucked in in the area of the groove in order to produce a narrow or thin "seam" here.

Im folgenden wird die Erfindung unter Hinweis auf die Zeichnung anhand eines Ausführungsbeispieles näher erläutert.in the The following is the invention with reference to the drawing of an embodiment explained in more detail.

Es zeigt:It shows:

1 eine schematische Ansicht zum Aufsprühen der ersten Farbe in dem ersten Formwerkzeug; 1 is a schematic view for spraying the first color in the first mold;

2 eine der 1 entsprechende Ansicht nach dem Aufsprühen der zweiten Farbe; 2 one of the 1 corresponding view after spraying the second color;

3 eine den 1 und 2 entsprechende Ansicht, jedoch nach dem Eingießen des Polyurethanmaterials zur Fertigstellung der Gießhaut; und 3 a den 1 and 2 corresponding view, but after pouring the polyure than materials for finishing the cast skin; and

4 einen schematischen Schnitt als Ausschnitt im vergrößerten Maßstab des zweiten Formwerkzeuges zur Fertigstellung des Formteiles. 4 a schematic section as a section on an enlarged scale of the second mold for completing the molded part.

In 1 ist das Unterwerkzeug 1 eines ersten Formwerkzeuges dargestellt, das einen Farbtrennvorsprung 2 aufweist, der zwei mit unterschiedlichen Farben zu lackierende Abschnitte trennt. Durch eine Sprühvorrichtung 4 wird die Farbe aufgespritzt. Die erste Farbe ist mit 5 bezeichnet. Der Bereich für die zweite Farbe ist durch eine Abdeckmaske 3 abgedeckt, die diesen zweiten Farbbereich zusammen mit dem Trennvorsprung 2 deutlich abdeckt.In 1 is the lower tool 1 of a first molding tool, which has a color separation projection 2 which separates two sections to be painted with different colors. Through a spray device 4 the paint is sprayed on. The first color is with 5 designated. The area for the second color is through a mask 3 covered that second color area together with the tab 2 clearly covers.

Nach dem Entfernen der Maske 3 kann die zweite Farbschicht 6 aufgespritzt werden (2). Im Bereich des Trennvorsprunges 2 ist ein Oberspray unschädlich, da die erste Farbe 5 bereits aufgebracht wurde.After removing the mask 3 can the second layer of paint 6 be sprayed on ( 2 ). In the area of the separation tab 2 an upper spray is harmless since the first color 5 has already been applied.

Im Anschluß daran wird die Gießhaut durch Eingießen des Polyurethanmaterials 7 fertiggestellt (3). Das Ausreagieren geschieht in einer geschlossenen Form, wobei das Oberwerkzeug in 3 nicht dargestellt ist.The pouring skin is then poured in by the polyurethane material 7 completed ( 3 ). The reaction takes place in a closed form, with the upper tool in 3 is not shown.

Die auf diese Weise hergestellte mehrfarbig lackierte Gießhaut wird aus dem ersten Formwerkzeug mit einer die Farben voneinander trennenden Nut entnommen und wird dann in das zweite Formwerkzeug eingelegt, von dem das Unterwerkzeug 13 in 4 erkennbar ist. In dem Unterwerkzeug 13 befindet sich ein sehr dünnes Trennblech 11. Die Gießhaut wird so aufgelegt, daß dieses Trennblech in der Nut liegt, die durch den Trennvorsprung 2 erzeugt wurde. Nach dem Einlegen der Gießhaut wird bei 12 Unterdruck angelegt, so daß die Gießhaut dicht an das dünne Trennblech 11 angezogen und dort fixiert wird. Die Nut ist dann sehr dünn und schmal, so daß sie in dem Endprodukt einen entsprechend schmalen Spalt bildet, der als saubere Naht in Erscheinung tritt.The multi-colored lacquered casting skin produced in this way is removed from the first mold with a groove separating the colors from one another and is then inserted into the second mold, from which the lower tool 13 in 4 is recognizable. In the lower tool 13 there is a very thin divider 11 , The casting skin is placed so that this divider lies in the groove through the separating projection 2 was generated. After inserting the pouring skin, at 12 Vacuum applied so that the casting skin is close to the thin divider 11 is tightened and fixed there. The groove is then very thin and narrow, so that it forms a correspondingly narrow gap in the end product, which appears as a clean seam.

Nach dem Einlegen der Gießhaut 7 wird dann das Oberwerkzeug 10 mit dem versteifenden Trägerteil 9 aufgesetzt. Anschließend wird das Polyurethanmaterial zur Herstellung der Schaumschicht 14 eingefüllt. Nach dem Aufschäumen kann das fertige Produkt aus dem zweiten Formwerkzeug entnommen werden, wobei eine saubere und schmale Naht zwischen den beiden Farben 5 und 6 vorhanden ist.After inserting the pouring skin 7 then becomes the top tool 10 with the stiffening support part 9 placed. The polyurethane material is then used to produce the foam layer 14 filled. After foaming, the finished product can be removed from the second mold, leaving a clean and narrow seam between the two colors 5 and 6 is available.
