Abstract

A leather grained pattern is used with a flexible material, preferably silicone, and a lower tool half(1,2) to produce a negative product(3). The pattern is removed leaving the negative product with undercuts to form part of the lower tool half. An upper tool part(5) then forms a molding cavity with the lower tool half and covers the parting line between both parts of the lower tool. Polyurethane is introduced and cured and the lower tool is then parted to deform the negative component and release the upper tool and shell molding(6). An Independent claim is also included for the molding tool whose lower tool half(1) has loose parts(2) which, in conjunction with the negative product, form undercuts on the molded shell while allowing easy demolding.

Description

Die Erfindung betrifft ein Verfahren und ein Formwerkzeug nach dem Oberbegriff des Anspruches 1 bzw. 2. The invention relates to a method and a molding tool according to the preamble of claim 1 or 2.

Gießhäute, die auf der sichtbaren Seite eine Narbung wie natürliche Lederhäute oder ähnliche Muster aufweisen, werden bei der Herstellung von Fahrzeuginnenausstattungen immer bedeutender. Die Anforderung an die Qualität dieser Gießhäute und an ihre Oberfläche nimmt ständig zu. Cast skins that have a grain on the visible side have natural leather hides or similar patterns always in the manufacture of vehicle interiors important. The requirement for the quality of these cast skins and its surface is constantly increasing.

Nach einem bekannten Verfahren werden derartige Gießhäute in einem geschlossenen Polyurethangießwerkzeug hergestellt, das eine Formunterhälfte und eine Formoberhälfte aufweist. Es liegt also ein geschlossener Formhohlraum vor, der die Dicke der Gießhaut definiert. Die Gießhäute sind kompliziert gestaltet und weisen Hinterschneidungen auf. Die Hinterschnittformung findet bei den bekannten Verfahren und in den bekannten Formwerkzeugen in den Formoberhälften statt. Hier sind zur Bildung der Hinterschneidungen und zur Ermöglichung der Entformung Losteile, d. h. Klappen oder Schieber vorgesehen. Zwischen der Formhälfte und den Losteilen entstehen Teilungsverläufe, die die Oberfläche der Gießhaut negativ beeinflussen. Die aus den Werkzeugteilungen resultierenden Unterbrechungen sind auf der sichtbaren Seite der Gießhaut erkennbar. According to a known method, such cast skins are in a closed polyurethane casting tool that has a lower mold half and an upper mold half. It So there is a closed mold cavity, which is the thickness of the cast skin. The cast skins are complicated designed and have undercuts. The Undercut shaping takes place in the known methods and in the known molding tools in the mold halves instead. Here are to form the undercuts and to enable the demolding of loose parts, d. H. Flaps or sliders intended. Form between the mold half and the loose parts Gradients that negatively affect the surface of the cast skin influence. The resulting from the tool divisions Interruptions are on the visible side of the cast skin recognizable.

Der Erfindung liegt nun die Aufgabe zugrunde, ein Verfahren und ein Formwerkzeug der eingangs genannten Art zu schaffen, durch das Gießhäute für Fahrzeuginnenverkleidungen mit Hinterschneidungen in geschlossenen Gießwerkzeugen hergestellt werden können, ohne daß es durch den Einsatz von Losteilen wie Schiebern oder Klappen zu einem schlechten optischen Gesamteindruck auf der sichtbaren Seite der Gießhaut kommt. Es soll auf der genarbten Seite keine Teilungsverläufe erkennbar sein. Gleichzeitig soll das Formwerkzeug einfach aufgebaut sein, so daß eine wirtschaftliche Herstellung möglich ist. The invention is based on the object of a method and to create a mold of the type mentioned at the outset, through the pouring skins for vehicle interior panels Undercuts made in closed molds can be made without the use of loose parts like sliders or flaps to a poor optical Overall impression comes on the visible side of the cast skin. It there should be no gradients on the grained side be recognizable. At the same time, the mold should be simple be built up so that economical production is possible is.

Diese Aufgabe wird grundsätzlich durch das Verfahren nach Anspruch 1 bzw. das Formwerkzeug nach Anspruch 2 gelöst. This task is basically followed by the procedure Claim 1 and the molding tool according to claim 2 solved.

Erfindungsgemäß ist das Oberwerkzeug relativ einfach ausgebildet. Das Unterwerkzeug, für das mehr Raum zur Verfügung steht und das "ortsfest" ist, weist die Losteile, d. h. die Klappen oder Schieber auf. Das Negativ aus flexiblem Material. das vorzugsweise ein Silikonnegativ ist, wird in der Unterformhälfte mit Hilfe eines Belederungsmodells hergestellt, das bei diesem ersten Verfahrensschritt die Formoberhälfte bildet. Nach dem Herstellen des Negativs aus flexiblem Material können die Losteile abgeklappt und das Belederungsmodell abgezogen werden. Nach dem die Losteile wieder ihre endgültige Form einnehmen, liegt eine Unterformhälfte vor, in der das Negativ aus flexiblem Material verblieben ist. Es wird nun die Oberformhälfte zugeführt, um den Formhohlraum zu definieren. Dieser wird begrenzt auf der einen Seite durch die Formoberhälfte und auf der anderen Seite durch das Negativ, das wie gesagt in der Formunterhälfte verblieben ist. In diesen Formhohlraum wird dann das Polyurethanmaterial eingegeben, so daß die Gießhaut entsteht. Das negativ weist eine Narbung auf, die in der Gießhaut abgebildet wird. Die Gießhaut ist mit Hinterschneidungen versehen. Nach dem Ausreagieren des Polyurethans werden die Losteile unter Deformierung des Negativs abgeklappt oder abgezogen. D. h. die Formunterhälfte wird geöffnet, wobei das Negativ entsprechend im flexiblen Bereich deformiert wird. Die Gießhaut mit den Hinterschneidungen kann dann entnommen werden. Gegebenenfalls nach einer Reinigung und Aufbereitung steht das Negativ für den nächsten Herstellungsvorgang zur Verfügung. According to the upper tool is relatively simple educated. The lower tool for which more space is available stands and that is "stationary", the lot parts, d. H. the Open flaps or sliders. The negative of flexible Material. which is preferably a silicone negative is in the Lower mold half made with the help of a leather model, the top half of the mold in this first process step forms. After making the negative from flexible Material can be folded down the loose parts and the leather model subtracted from. After the raffle parts theirs again take the final shape, there is a lower mold half in which the Negative from flexible material is left. It will now the top mold half fed to the mold cavity define. This is limited on one side by the Top of the mold and on the other side by the negative, the as stated in the lower half of the mold. In these Mold cavity is then entered the polyurethane material, so that the cast skin is created. The negative indicates a grain that is imaged in the cast skin. The casting skin is provided with undercuts. After the reaction of the The loose parts are deformed by polyurethane Negatives folded or subtracted. I.e. the bottom of the mold will opened, the negative accordingly in the flexible area is deformed. The cast skin with the undercuts can then be removed. If necessary after cleaning and preparation is the negative for the next Manufacturing process available.

Zusammenfassend kann festgestellt werden, daß durch Verwendung des Negativs als Teil des Gießwerkzeuges eine Herstellung und Entformung von Gießhäuten mit Hinterschneidungen möglich ist, wobei das Negativteil die Formunterhälfte ist. In summary it can be said that by Using the negative as part of the casting tool Production and demolding of cast skins with undercuts is possible, the negative part being the lower part of the mold.

Im folgenden wird die Erfindung unter Hinweis auf die Zeichnung anhand eines Ausführungsbeispieles näher erläutert. In the following the invention with reference to the Drawing explained in more detail using an exemplary embodiment.

Es zeigt: It shows:

Fig. 1 einen Schnitt durch eine Ausführungsform eines Formwerkzeuges bei der Herstellung eines Negativs aus flexiblem Material mit Hilfe eines Belederungsmodells; Fig. 1 shows a section through an embodiment of a mold in the manufacture of a negative of flexible material by means of a Belederungsmodells;

Fig. 2 eine der Fig. 1 entsprechende Ansicht, wobei das Belederungsmodell durch die obere Formhälfte zur Bildung des Formhohlraumes für die Gießhaut ersetzt wurde; FIG. 2 shows a view corresponding to FIG. 1, the leather model being replaced by the upper mold half to form the mold cavity for the casting skin;

Fig. 3 eine der Fig. 2 entsprechende Ansicht, jedoch nach Herstellung der Gießhaut mit abgeklappten Losteilen und deformiertem Negativ zur Freigabe der Gießhaut mit den Hinterschneidungen; und Fig. 3 is a view corresponding to Figure 2, but after preparation of the cast skin with folded loose parts and deformed to release the negative cast skin with the undercuts. and

Fig. 4 eine der Fig. 3 entsprechende Ansicht mit der fertigen Gießhaut, die entnommen werden kann. Fig. 4 is a view corresponding to Fig. 3 with the finished casting skin, which can be removed.

In der Zeichnung ist schematisch ein Formwerkzeug in verschiedenen Stellungen zur Herstellung einer Gießhaut aus Polyurethan mit genarbter Oberfläche dargestellt. Die Gießhaut ist mit 6 bezeichnet. In the drawing, a mold is shown schematically in different positions for the production of a cast skin Shown polyurethane with grained surface. The cast skin is designated 6.

In Fig. 1 ist das Unterwerkzeug 1 dargestellt, das Losteile in Form von Klappen 2 aufweist. In der gezeigten Stellung wird ein Formhohlraum mit Hinterschneidungen H durch ein Belederungsmodell 4 gebildet. Mit Hilfe des Formhohlraumes wurde ein Negativ 3 aus flexiblem Material, in diesem Falle ein Silikonnegativ hergestellt. Auf der Innenseite wurde mit Hilfe der Oberfläche des Belederungsmodells eine Narbung auf das Negativ 3 übertragen. In Fig. 1, the lower tool 1 is shown, which has loose parts in the form of flaps 2 . In the position shown, a mold cavity with undercuts H is formed by a leather model 4 . With the help of the mold cavity, a negative 3 was made of flexible material, in this case a silicone negative. A grain was transferred to the negative 3 on the inside using the surface of the leather model.

Nach dem Abklappen der Klappen 2 kann das Belederungsmodell entnommen werden, da das Negativ entsprechend deformierbar ist, so daß Hinterschneidungen H das Abziehen des Belederungsmodells 4 nicht behindern. Das Belederungsmodell 4 wird dann durch die Formoberhälfte 5 ersetzt wie in Fig. 2 dargestellt. Es bleibt ein Formhohlraum frei. Die Abdichtung bei A mit Hilfe des Negativs 3 zwischen der Formoberhälfte 5 und den Klappen 2. Die Teilungsverläufe zwischen den Klappen 2 und der Formunterhälfte 1 sind durch das Negativ 3 abgedeckt. After the flaps 2 have been folded down, the leather model can be removed, since the negative can be deformed accordingly, so that undercuts H do not impede the removal of the leather model 4 . The leather model 4 is then replaced by the upper mold 5 as shown in Fig. 2. A mold cavity remains free. The seal at A using the negative 3 between the upper mold 5 and the flaps 2 . The gradients between the flaps 2 and the lower mold half 1 are covered by the negative 3 .

In den Formhohlraum wird nun das Polyurethanmaterial zur Bildung der Gießhaut eingegeben. Wenn dieses Material ausgehärtet ist, können die Klappen 2 abgeklappt werden, wobei sich das Negativ aufgrund seiner flexiblen Eigenschaften mit bewegt, d. h. entsprechend deformiert wird, wie es in Fig. 3 dargestellt ist. Nun ist es möglich, die Formoberhälfte 5 abzuziehen, obwohl die Gießhaut 6 Hinterschneidungen aufweist. Die Gießhaut ist ebenfalls flexibel, so daß schließlich die in Fig. 4 gezeigte Position eingenommen wird. In dieser Stellung kann die Gießhaut 6, die fertig ist und Hinterschneidungen aufweist, entnommen werden. Das Negativ 3 steht für die Herstellung der nächsten Gießhaut zur Verfügung. The polyurethane material for forming the casting skin is now introduced into the mold cavity. When this material has hardened, the flaps 2 can be folded down, the negative also moving due to its flexible properties, ie being deformed accordingly, as shown in FIG. 3. It is now possible to pull off the upper mold 5 , although the cast skin 6 has undercuts. The casting skin is also flexible, so that finally the position shown in Fig. 4 is adopted. In this position, the casting skin 6 , which is finished and has undercuts, can be removed. The negative 3 is available for the production of the next casting skin.
