Des Weiteren beschreibt die Erfindung ein Verfahren zur Herstellung eines erfindungsgemäßen Kunststoffbauteils in einem zwei Werkzeughälften enthaltendem Schäumwerkzeug.Of Furthermore, the invention describes a method for the production a plastic component according to the invention in a two mold halves containing Foaming.

Nach dem erfindungsgemäßen Verfahren wird bei geöffnetem Schäumwerkzeug ein Träger, welcher einen Steg aufweist, in der einen Werkzeughälfte angeordnet, so, dass der Steg in die Kavität des Schäumwerkzeugs hineinragt. In die zweite Werkzeughälfte werden zumindest zwei Dekorfolien auf diese Weise eingelegt, dass die Dekorfolien sich in ihren Endbereichen überlappen, und die Endbereiche in die Kavität des Schäumwerkzeugs hineinragen. Nach Schließen des Schäumwerkzeugs werden Träger und Dekorfolien hinterschäumt, wobei der Steg des Trägers und der Überlappungsbereich der Dekorfolien so angeordnet sind, dass während der Hinterschäumung der Überlappungsbereich der Dekorfolien zumindest teilweise an den Steg des Trägers gepresst wird.To the method according to the invention is when open foaming a carrier, which a web, in which a tool half arranged, so that the Footbridge into the cavity of the foaming protrudes. In the second half of the tool at least two Decor foils inserted in this way that the decorative foils are in overlap their end areas, and the end areas in the cavity of the foaming tool protrude. After closing of the foaming tool become carriers Foamed back and decor foils, being the bridge of the wearer and the overlap area the decorative films are arranged so that during the foam backing of the overlap region the decorative films at least partially pressed against the web of the wearer becomes.

Die Hinterschäumung führt zusätzlich zu einem Verkleben der Dekorfolien miteinander und einem Verkleben der Dekorfolien mit dem Steg. Dies ist insbesondere dann der Fall, wenn die stegäußere Haut kürzer ist als die steginnere Haut, wodurch das teilweise Eindringen des Schaums in die Zwischenbereiche Dekorfolie-Dekorfolie und Steg-Dekorfolie erleichtert wird.The foam backing leads in addition to a bonding of the decorative films together and a bonding the decorative films with the bridge. This is especially the case if the stegausere Haut shorter is as the inner skin, whereby the partial penetration of the Foam into the intermediate areas decorative foil decorative foil and web decorative foil facilitates becomes.

Der Steg ist notwendig, um die Nahtlinie der Dekorfolien zu positionieren und zu stabilisieren. Diesbe züglich ist es insbesondere vorteilhaft, wenn der Steg senkrecht zum Träger und zur Oberfläche der Dekorfolien angeordnet ist. Auch muss der Steg eine gewisse Höhe haben, um genannte Funktionen erfüllen zu können. Der Bereich, in dem man die Höhe des Stegs variieren kann, ist insbesondere abhängig von der Dicke der Schaumschicht, d.h., vom Abstand zwischen Träger und Dekoroberfläche. Vorteilhaft ist aber eine Höhe des Stegs von mindestens 5mm.Of the Bridge is necessary to position the seam line of the decorative foils and to stabilize. Diesbe free It is particularly advantageous if the web perpendicular to the carrier and to the surface of the Decor foils is arranged. Also, the bridge must have a certain height, to fulfill these functions to be able to. The area where you can see the height Depending on the thickness of the foam layer, that is, the distance between carriers and decor surface. But a height is advantageous of the bridge of at least 5mm.

Während des Hinterschäumens werden durch den Druck des Schaums die Dekorfolien gegen den Träger bzw. Steg abgedichtet, so dass kein Schaum in den Sichtbereich tritt. Vorteilhaft ist allerdings ein teilweises Eindringen des Schaums zwischen die Dekorfolien und zwischen Dekorfolien und Steg zwecks Fixierung und Verklebung der Dekorfolien miteinander und von Dekorfolien und Steg.During the rear-foaming be the pressure of the foam, the decorative films against the carrier or Bar sealed, so that no foam enters the field of view. However, a partial penetration of the foam is advantageous between the decorative foils and between decorative foils and bridge in order Fixing and gluing the decorative foils together and decor foils and footbridge.

Eine vorteilhafte Weiterbildung des Verfahrens sieht vor, dass in der Werkzeughälfte, in der die Dekorfolien platziert werden, ein Schwert zur Erzeugung einer Nut im Schnittstellenbereich zweier Dekorfolien angeordnet wird.A advantageous development of the method provides that in the Tool half, in which the decorative foils are placed, a sword to produce a groove arranged in the interface region of two decorative films becomes.

Wird ein Schwert verwendet, so wird eine Dekorfolie an der einen Seite des Schwertes angelegt, die andere Dekorfolie an der anderen Seite des Schwerts, und die Endbereiche der Dekorfolien oberhalb des Schwerts, in die Kavität hineinragend, überlappend zusammengeführt. Die Lage des Schwerts ist dabei mit der Lage des Stegs des Trägers abgestimmt, so dass beim Hinterschäumen der Überlappungsbereich der Dekorfolien zumindest teilweise an den Steg gepresst wird.Becomes a sword is used, so is a decorative foil on one side the sword is applied, the other decorative foil on the other side of the sword, and the end portions of the decorative sheets above the sword, into the cavity protruding, overlapping merged. The position of the sword is coordinated with the position of the web of the wearer, so that when backfoaming the overlap area the decorative films is at least partially pressed against the web.

Durch das Schwert ist der Verlauf der Nahtlinie zwischen den beiden Dekorfolien exakt festgelegt.By the sword is the course of the seam line between the two decorative foils set exactly.

Je nach Höhe und Breite des Schwerts weist das Kunststoffbauteil nach Fertigstellung entlang der Nahtlinie eine Nut auf, die den Maßen des Schwerts entspricht. Durch das Schwert wird somit ein optischer Effekt der Dekoroberfläche erzeugt. Über die Änderung der Abmaße des Schwerts kann dieser optische Effekt verändert werden.ever by height and width of the sword has the plastic component after completion along the seam line a groove corresponding to the dimensions of the sword. The sword thus creates an optical effect of the decorative surface. About the change the dimensions of the sword, this optical effect can be changed.

Die Erfindung wird nun anhand einer Figur erläutert.The Invention will now be explained with reference to a figure.

Die Figur zeigt ein erfindungsgemäßes Kunststoffbauteil 1 mit einer Dekoroberfläche. Das Kunststoffbauteil 1 enthält einen Träger 2, zwei die Dekoroberfläche bildenden Dekorfolien 3, 4 und eine sich zwischen dem Träger 2 und Dekorfolien 3, 4 befindende Schaumschicht 5. Des Weiteren weist der Träger 2 einen Steg 6 auf, der senkrecht auf der Grundfläche des Trägers steht, und in die Schaumschicht 5 hineinragt.The figure shows a plastic component according to the invention 1 with a decorative surface. The plastic component 1 contains a carrier 2 , two decor sheets forming the decorative surface 3 . 4 and one between the wearer 2 and decorative films 3 . 4 located foam layer 5 , Furthermore, the wearer points 2 a footbridge 6 which is perpendicular to the base of the carrier, and in the foam layer 5 protrudes.

Die Dekorfolien 3 und 4 sind in einer gemeinsamen ebene nebeneinander liegend auf der Schaumschicht 5 angeordnet. In ihrem gemeinsamen Schnittstellenbereich ist der Endbereich der Dekorfolie 3 in Richtung Träger abgeknickt, so dass der Endbereich der Dekorfolie 3 sich senkrecht zum Träger befindet. Der Endbereich der Dekorfolie 4 ist in Form einer Stufe in Richtung Träger abgeknickt. Nach der Stufe überlappen sich die Endbereiche der Dekorfolien 3 und 4. Durch die Endbereiche der Dekorfolien 3 und 4 wird somit eine Nut 7 gebildet.The decorative films 3 and 4 are in one common seed level next to each other on the foam layer 5 arranged. In their common interface area is the end area of the decorative film 3 bent in the direction of the carrier, so that the end of the decorative film 3 is perpendicular to the carrier. The end area of the decorative foil 4 is bent in the form of a step towards the wearer. After the step, the end areas of the decorative films overlap 3 and 4 , Through the end areas of the decorative films 3 and 4 thus becomes a groove 7 educated.

Die Überlappung der Endbereiche der beiden Dekorfolien 3 und 4 ragt senkrecht in die Schaumschicht 5 hinein. Dabei grenzt die eine Seite der Überlappung, die durch den Endbereich der Dekorfolie 3 gebildet wird, an den Steg 6 des Trägers 2, die andere Seite der Überlappung, die durch den Endbereich der Dekorfolie 4 gebildet wird, grenzt an die Schaumschicht 5.The overlap of the end areas of the two decorative foils 3 and 4 protrudes vertically into the foam layer 5 into it. In the process, one side of the overlap borders the end of the decorative film 3 is formed, to the dock 6 of the carrier 2 , the other side of the overlap, passing through the end of the decorative film 4 is formed adjacent to the foam layer 5 ,

Die Höhe des Stegs 6 ist hierbei so gewählt, dass Boden der Nut 7 und Oberkante des Stegs 6 in einer gemeinsamen Ebene liegen.The height of the jetty 6 is chosen so that the bottom of the groove 7 and top of the bridge 6 lie in a common plane.

Der Endbereich der Dekorfolie 3 geht tiefer in die Schaumschicht 5 hinein als der Endbereich der Dekorfolie 4. Somit grenzt auch ein kleiner Bereich der Dekorfolie 3 direkt an die Schaumschicht 5.The end area of the decorative foil 3 goes deeper into the foam layer 5 in as the end portion of the decorative sheet 4 , Thus, also borders a small area of the decorative film 3 directly to the foam layer 5 ,

Als Material für den Träger wurde in diesem Beispiel Polypropylen verwendet. Die Dekorfolie 3 und die Dekorfolie 4 sind thermoformbare Folien aus einem thermoplastischen Elastomer. Die Schaumschicht 5 ist geschäumtes Polyurethan.As the material for the carrier, polypropylene was used in this example. The decorative foil 3 and the decorative foil 4 are thermoformable films of a thermoplastic elastomer. The foam layer 5 is foamed polyurethane.

Hergestellt wurde das eben beschriebene Kunststoffbauteil nach dem erfindungsgemäßen Verfahren in einem Schäumwerkzeug. Das Schäumwerkzeug besteht aus zwei Werkzeughälften. In der zweiten Werkzeughälfte ist ein Schwert angeordnet.Produced was the plastic component just described by the method according to the invention in a foaming tool. The foaming tool consists of two mold halves. In the second half of the mold is a sword arranged.

Bei geöffnetem Schäumwerkzeug wurde der Träger 2 in der ersten Werkzeughälfte angeordnet, so dass der Steg 6 in die Kavität des Schäumwerkzeugs hineinragte.When the foaming tool was open, the carrier became 2 arranged in the first tool half, leaving the bridge 6 protruding into the cavity of the foaming tool.

Die zwei Dekorfolien 3 und 4 wurden in der zweiten Werkzeughälfte auf die Weise angeordnet, dass eine Dekorfolie an der einen Seite des in der zweiten Werkzeughälfte angeordneten Schwertes flächig an grenzte, und die andere Dekorfolie an die andere Seite des Schwertes flächig angrenzte. Die Endbereiche der beiden Dekorfolien 3 und 4 wurden oberhalb des Schwertes zusammengeführt, so dass sie sich überlappten. In Position gehalten wurden die Dekorfolien durch Fixierung am Außenrand und durch Ansaugen mittels Vakuum.The two decorative foils 3 and 4 were arranged in the second mold half in such a way that a decorative film on one side of the arranged in the second tool half sword bordered flat, and the other decorative film to the other side of the sword flatly adjacent. The end areas of the two decorative foils 3 and 4 were brought together above the sword so that they overlapped. The decorative foils were held in position by fixing on the outer edge and by vacuum suction.

Danach wurde das Werkzeug geschlossen und der Hinterschäumprozess gestartet. Durch das Hinterschäumen wurde der Überlappungsbereich der beiden Dekorfolien an den Steg 6 gepresst. Dadurch, dass die Dekorfolie 4 etwas kürzer ist als die Dekorfolie 3, drang der Schaum teilweise in die Zwischenbereiche Dekorfolie 3 – Dekorfolie 4 und Steg – Dekorfolie 3 ein. Das Hinterschäumen führte zu einem kraftschlüssigen Verbund des Überlappungsbereichs der beiden Dekorfolien 3 und 4 sowie dem Steg 6.Thereafter, the tool was closed and the foam process started. The overlap area of the two decorative foils on the bridge became foamy due to backfoaming 6 pressed. Thereby, that the decor foil 4 a little shorter than the decorative foil 3 , the foam partially penetrated into the intermediate areas decorative film 3 - decorative foil 4 and bridge - decorative foil 3 one. The foam backing resulted in a frictional connection of the overlapping area of the two decorative films 3 and 4 as well as the jetty 6 ,

Nach Beendigung des Hinterschäumvorgangs wurde das Kunststoffbauteil entnommen.To Termination of the foam process the plastic component was removed.

Das so hergestellte Kunststoffbauteil weist eine Dekoroberfläche auf, die aus zwei Dekorfolien 3 und 4 besteht. Die Schnittlinie der beiden Dekorfolien wird durch eine Nut 7 gebildet, die durch den Abdruck des Schwertes des Schäumwerkzeugs erzeugt wurde.The plastic component produced in this way has a decorative surface which consists of two decorative films 3 and 4 consists. The cutting line of the two decorative films is through a groove 7 formed by the impression of the sword of the foaming tool.

In diesem Ausführungsbeispiel sind Nut und Steg versetzt angeordnet. Es ist aber ebenfalls möglich, die Nut auch direkt über den Steg zu platzieren. Die Dekorfolien müssen dann entsprechend der Position von Steg und Schwert angeordnet werden.In this embodiment Groove and web are staggered. But it is also possible that Nut also directly over to place the bridge. The decorative films must then according to the Position of bridge and sword are arranged.
