Description

• I I 1• I I 1

Die Erfindung betrifft für PKW-Aufbauten bestimmte Preßlinge, d.h. Preßformkörper, aus Kunststoff, wie Stoßstangen und/oder andere Teile, die starken mechanischen Beanspruchungen ausgesetzt sind.The invention relates to compacts, i.e. molded articles, made of plastic, such as bumpers, intended for automobile bodies and / or other parts that are exposed to strong mechanical loads.

Aufgabe der Erfindung ist es, einen Preßformkörper für die verschiedensten Anwendungsgebiete, insbesondere für Kraftfahrzeugteile, zu schaffen, der mühelos und wirtschaftlich hersteilbar ist und dabei gleichzeitig eine hohe Festigkeit und Stabilität aufweist.The object of the invention is to provide a compression molding for a wide variety of fields of application, in particular for motor vehicle parts, to create that effortlessly and economically is producible and at the same time has a high strength and stability.

Der erfindungsgemäße Preßformkörper, wie insbesondere Stoßstange für Kraftfahrzeuge, ist dadurch gekennzeichnet, daß er aus zwei Kunststoffarten besteht, die unterschiedliche Eigenschaften aufweisen und unmittelbar nacheinander in die gleiche Form spritzgegossen werden.The compression molding according to the invention, such as in particular Bumper for motor vehicles, is characterized in that it consists of two types of plastic, which are different Have properties and immediately one after the other be injection molded into the same mold.

Dabei wird im einzelnen zunächst der Kunststoff, der die Außenfläche des Preßformkörpers bilden soll, und gleich danach der zweite Kunststoff eingespritzt, aus dem das Innere des Preßformkörpers bestehen soll.In this case, first of all the plastic that is to form the outer surface of the compression molding, and Immediately thereafter, the second plastic is injected, from which the interior of the compression molding is to be made.

Der Kunststoff, der als erster in einer Menge eingespritzt wird, die nicht genügt, um die Form zu füllen, ist unter Kunststoffen mit hoher Witterungsbeständigkeit, Kerbschlagzähigkeit und guter Ofenlackierbarkeit gewählt«The plastic that is first injected is in an amount insufficient to fill the mold Chosen among plastics with high weather resistance, notched impact strength and good oven paintability «

Der Kunststoff für das zweite Einspritzen muß dagegen hohe mechanische Festigkeit aufweisen und als Füllträger der Hülle dienen, die aus dem zuerst eingespritzen Kunststoff besteht.The plastic for the second injection, however, must have high mechanical strength and as a filler carrier Serve envelope, which consists of the first injected plastic.

Eine weitere Eigenschaft des Gegenstandes der Erfindung besteht darin, daß sich durch Anwendung von an sich be-Another property of the subject matter of the invention is that by applying inherently

kannten, besonderen Spritzgußverfahren Gegenstände herstellen lassen, die eine ungleichmäßige, gegenüber ihrer Länge oder ihrer Oberfläche differenzierte Festigkeit aufweisen. Diese Möglichkeit wird bei der Herstellung von Kraftfahrzeug-Stoßstangen sowie bei der Herstellung von Innen- und Außenaufbauteilen weitgehendst ausgenutzt, bei denen besondere Festigkeitseigenschaften verlangt worden.knew special injection molding processes to produce objects that have an uneven strength that is differentiated in relation to their length or their surface. This possibility is used in the manufacture of motor vehicle bumpers as well as in the manufacture of interior and exterior bumpers External structural parts are used to the greatest possible extent, where special strength properties were required.

Vom erfindungsgemäßen Preßformkörper wird nachstehend an Hand der beigefügton Zeichnung ein Ausführungsbeispiel beschrieben. Es zeigenThe compression molding according to the invention is described below an exemplary embodiment is described with reference to the accompanying drawing. Show it

Fig. 1 eine perspektivische Teilansicht einer Stoßstange im Schnitt, undFig. 1 is a partial perspective view of a bumper in section, and

Fig. 2 ähnlich wie Fig. 1, eine Variante des Querprofils der Stoßstange.FIG. 2, similar to FIG. 1, shows a variant of the transverse profile the bumper.

Unter Bezugnahme auf die Zeichnung umfaßt ein Preßformkörper 5 gemäß der Erfindung in Form einer Stoßstange aus Kunststoff einen Außenteil 6, 6a bzw. 6, 6b und einen Innenteil 7 bzw. 7a. Der erste Teil, d.h. der Außenteil 6, 6a bzw. 6, 6b ist aus einem Kunststoff ausgeführt, der hohe Witterungsbeständigkeit aufweist und in der Lage ist, eine Heißlackierung gut auszuhalten.With reference to the drawing, a compression molding 5 according to the invention comprises in the form of a bumper made of plastic, an outer part 6, 6a or 6, 6b and an inner part 7 or 7a. The first part, i.e. the outer part 6, 6a or 6, 6b is made of a plastic that has high weather resistance and is able to withstand a hot paint job well.

Der Innenteil 7, 7a besteht dagegen aus einem Kunststoff mit hoher mechanischer Festigkeit.The inner part 7, 7a, however, consists of a plastic with high mechanical strength.

Der Kunststoff, aus dem der Teil 6 besteht, wird als erster in die Form eingespritzt, und zwar in einer vorbestimmten Menge, die genügt, um den Formraum zu füllen, der das Bild negativ nachformt. Der Kunststoff für den Teil 7, 7a wird unter Kunststoffen mit geeigneter mechanischer Fe-The plastic from which the part 6 is made is first injected into the mold, in a predetermined manner Amount that is sufficient to fill the mold space that reshapes the image negatively. The plastic for part 7, 7a is listed among plastics with suitable mechanical strength

stigkeit gewählt und in einer vorbestimmten Masse sofort danach eingespritzt, die das Material 6 gegen die Innenwände der Form drückt.stigkeit selected and immediately to a predetermined extent then injected, which presses the material 6 against the inner walls of the mold.

So wird ein Preßformkörper 5 aus zwei Bestandteilen ausgeführt; und zwar aus dem sichtbaren, irgenwie lackierten oder lackierbaren Außenteil 6 und aus dem inneren Verstärkungsteil 7, 7a anstelle von Metallbewehrungen.Thus, a compression molding 5 is made from two components; namely from the visible, somehow varnished or paintable outer part 6 and from the inner reinforcement part 7, 7a instead of metal reinforcements.

Die Rippen 6a bzw. 6b, wie auch das sichtbare Profil des Preßforr'-örpers, werden durch die Form bestimmt, die in Abhängigkeit von der für den Preßformkörper vorgesehenen Anwendung gebaut wird.The ribs 6a and 6b, as well as the visible profile of the Preßforr'-örpers, are determined by the shape, depending on the provided for the compression molding Application is built.

Die so erfindungsgemäß ausgeführten Kraftfahrzeug-Stoßstangen sind leicht, wirtschaftlich und sehr schlagfest, und zwar auch dank der betächtlichen Fähigkeit, sich innerhalb wohlbekannter Grenzen und abhängig von den Eigenschaften der beiden verwendeten Kunststoffe elastisch zu verformen.The motor vehicle bumpers embodied in accordance with the invention are light, economical and very impact-resistant, thanks in part to their considerable ability to elastic within well-known limits and depending on the properties of the two plastics used to deform.

Mit demselben Spritzgießverfahren mit zwei Kunststoff arten lassen sich Türen für Kraftfahrzeug-Aufbauten, Kotflügel, Hauben, Instrumentenbretter und sämtliche, nicht mit mechanischen, beweglichen Teilen verbundenen Elemente vorteilhaft herstellen.Using the same injection molding process with two plastic Doors for motor vehicle superstructures, fenders, hoods, instrument panels and all of them cannot be types Manufacture elements connected to mechanical, moving parts advantageous.

Selbstverständlich ist der neuerungsgemäße Gegenstand nicht auf das beschriebene und" dargestellte Beispiel beschränkt, sondern umfaßt alle ähnlichen und gleichwertigen Ausführungen.Of course, the subject of the innovation is not limited to the example described and shown, but includes all similar and equivalent Executions.
