Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Formwerkzeugs nach den Merkmalen des Oberbegriffs des Anspruchs 1, ein Formwerkzeug nach den Merkmalen des Oberbegriffs des Anspruchs 3 und ein Verfahren zur Herstellung eines Formteils nach den Merkmalen des Oberbegriffs des Anspruchs 4.The invention relates to a method for producing a molding tool according to the features of the preamble of
Aus dem Stand der Technik sind Kunststoffteile beispielsweise aus dem Möbelbereich oder dem Elektronikgerätebereich bekannt, welche eine flächendeckend matte oder glänzende Oberfläche aufweisen. Des Weiteren ist ein so genannter Klavierlackeffekt bekannt, welcher durch ein Ausformen der Kunststoffteile in zwei aufeinander folgenden Spritzgussprozessen mit zwei verschiedenen Werkstoffkomponenten erzeugt wird. Weiterhin sind Bauteile bekannt, welche eine dreidimensional wirkende Oberfläche aufweisen. Diese dreidimensional wirkende Oberfläche wird durch ein Hinterspritzen von relativ dicken Folien erzeugt.From the state of the art plastic parts are known, for example from the furniture sector or the electronic equipment sector, which have a surface matt or glossy surface. Furthermore, a so-called piano lacquer effect is known, which is produced by molding the plastic parts in two successive injection molding processes with two different material components. Furthermore, components are known which have a three-dimensional acting surface. This three-dimensional surface is produced by injecting relatively thick films.
Zum Ausformen von Kunststoffteilen mittels Spritzgießen ist das Gasaußendruckverfahren bekannt. Dabei wird zwischen einer Werkzeugwand des Formwerkzeugs und einer Formteilaußenhaut des aus Kunststoff herzustellenden Formteils durch Einbringen eines Gases ein Gaspolster erzeugt, um dadurch Einfallstellen auf einer gegenüberliegenden Sichtseite des Formteils zu verhindern.For molding plastic parts by injection molding, the external gas pressure method is known. In this case, a gas cushion is generated between a mold wall of the mold and a molded outer skin of the molded plastic part by introducing a gas, thereby preventing sink marks on an opposite visible side of the molded part.
Der Erfindung liegt die Aufgabe zugrunde, ein verbessertes Formwerkzeug, ein verbessertes Verfahren zu dessen Herstellung und ein verbessertes Verfahren zur Herstellung eines Formteils anzugeben.The invention has for its object to provide an improved mold, an improved method for its production and an improved method for producing a molded part.
Die Aufgabe wird erfindungsgemäß durch ein Verfahren zur Herstellung eines Formwerkzeugs mit den Merkmalen des Anspruchs 1, ein Formwerkzeug mit den Merkmalen des Anspruchs 3 und ein Verfahren zur Herstellung eines Formteils mit den Merkmalen des Anspruchs 4 gelöst.The object is achieved by a method for producing a mold with the features of
Bevorzugte Ausgestaltungen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.Preferred embodiments and further developments of the invention are specified in the dependent claims.
In einem Verfahren zur Herstellung eines Formwerkzeugs zum Ausformen von Formteilen wird erfindungsgemäß eine Formwerkzeuginnenfläche zumindest bereichsweise thermisch, chemisch und/oder mechanisch bearbeitet, um auf der Formwerkzeuginnenfläche eine Negativstruktur zu erzeugen, mittels welcher auf einer Formteiloberfläche des mit dem Formwerkzeug ausformbaren Formteils eine korrespondierende Positivstruktur erzeugbar ist.In a method for producing a mold for molding of shaped parts, a mold inner surface is at least partially thermally, chemically and / or mechanically processed to produce a negative structure on the inner surface of the mold, by means of which a corresponding positive structure can be produced on a mold surface of the molding which can be formed with the mold is.
Mit dem auf diese Weise hergestellten Formwerkzeug können beispielsweise durch Spritzgießen oder Spritzprägen auf einfache und kostengünstige Weise aus Kunststoff Formteile mit einer ansprechenden hochwertigen Optik, beispielsweise mit einem Matt- und/oder Glanzeffekt und/oder mit dreidimensionalen Strukturen auf der Formteiloberfläche hergestellt werden, zum Beispiel Zier- und Verblendungsteile im Automobilbereich, in der Möbelindustrie oder im Konsumgüterbereich.With the mold produced in this way can be produced for example by injection molding or injection compression molding in a simple and cost-effective manner plastic molded parts with an attractive high-quality optics, for example with a matte and / or gloss effect and / or with three-dimensional structures on the molding surface, for example Decorative and veneering parts in the automotive sector, in the furniture industry or in the consumer goods sector.
Die Formwerkzeuginnenfläche kann beispielsweise durch Laserstrahlung, Ätzen, Fräsen und/oder durch Elektroerosion bearbeitet werden. Die durch diese Form der Bearbeitung ermöglichten hohen Freiheitsgrade ermöglichen das Erzeugen beliebiger Negativstrukturen auf der Formwerkzeuginnenfläche und dadurch das Erzeugen entsprechender korrespondierender Positivstrukturen auf mittels des Formwerkzeugs erzeugten Formteilen, zum Beispiel regelmäßige oder unregelmäßige Strukturen, welche einem Konturverlauf des Formteils folgen können oder von diesem abweichen können, als dreidimensionale Elemente oder mit geringster Tiefe.The inner surface of the mold can be processed, for example, by laser radiation, etching, milling and / or by electrical erosion. The high degrees of freedom made possible by this form of machining make it possible to produce any negative structures on the inner surface of the mold and thereby to generate corresponding positive structures on moldings produced by the mold, for example regular or irregular structures which may follow a contour of the molded part or deviate therefrom , as three-dimensional elements or with the least depth.
Es können alle hinterschnittfreien Muster, Bilder oder Entwürfe einen Bruchteil eines Millimeters oder bis zu mehreren Millimetern tief in die Formwerkzeuginnenfläche als Negativstruktur eingebracht werden, um mittels des Formwerkzeugs ein Formteil mit einer entsprechenden Positivstruktur zu erzeugen. Um die auf diese Weise ausgebildete Formteiloberfläche zu schützen, kann in einem nachfolgenden Beschichtungsvorgang eine Deckschicht beispielsweise aus Kunststoff oder Lack aufgebracht werden.All undercut-free patterns, images or designs can be introduced a fraction of a millimeter or up to several millimeters deep into the inner surface of the mold as a negative structure in order to produce a molded part with a corresponding positive structure by means of the mold. In order to protect the molded part surface formed in this way, a cover layer, for example made of plastic or lacquer, can be applied in a subsequent coating process.
