Formwerkzeug mit Beschichtung BeschreibungMolding tool with coating Description

Die Erfindung betrifft ein Formwerkzeug mit Beschichtung aus einer Hartschicht.The invention relates to a molding tool with a coating made of a hard layer.

Unter einem Formwerkzeug oder Umformwerkzeug wird ein Spritzgießwerkzeug, ein Preßwerkzeug, ein Ziehwerkzeug, ein Stanzwerkzeug oder dergleichen verstanden. Eine Hartschicht in Form einer Nitridschicht wird im Lichtbogen aufgebracht und dient dem Verschleißschutz. In vielen Fällen ist bei der Bewegung der Werkzeuge ein Gleiteffekt oder Schmiereffekt erwünscht, der durch die Hartschicht verhindert wird.A molding tool or forming tool is understood to be an injection molding tool, a pressing tool, a drawing tool, a punching tool or the like. A hard layer in the form of a nitride layer is applied in the arc and serves to protect against wear. In many cases, a sliding or lubricating effect is desired when the tools are moved, which is prevented by the hard layer.

Aufgabe der Erfindung ist die Bereitstellung eines Gleiteffekts auf derartigen Hartschichten.The object of the invention is to provide a sliding effect on such hard layers.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß auf die Hartschicht eine Weichbeschichtung unter Druck implantiert ist.This object is achieved according to the invention in that a soft coating is implanted under pressure onto the hard layer.

Die Erfindung unterscheidet sich insofern vom Stand der Technik, als die Weichbeschichtung den Reibbeiwert verrringert und einen schmierungsfreien Lauf sicherstellt.The invention differs from the prior art in that the soft coating reduces the coefficient of friction and ensures lubrication-free operation.

Eine besonders dauerhafte Gleitschicht wird durch eine Weichbeschichtung aus Wolframdisulfid erzielt.A particularly durable sliding layer is achieved by a soft coating made of tungsten disulfide.

Ein Ausführungsbeispiel der Erfindung wird anhand der Schemazeichnung erläuert.An embodiment of the invention is explained using the schematic drawing.

Das Ausführungsbeispiel stellt ein Formwerkzeug 1 dar. Der Kern 2 des Formwerkzeugs 1 ist mit einer Hartschicht 3 in Form einer Nitridschicht versehen. Auf die Hartschicht 3 ist eine Weichbeschichtung 4 unter Druck auf oder in die Oberfläche implantiert. Wolframdisulfid wird in Pulverform unter Druck aufgebracht oder aufgetragen und fügt sich fest auf die Hartschicht. Dadurch bleibt der Verschleißschutz durch die Hartschicht voll wirksam. Außerdem wird die Reibung herabgesetzt, so daß das Formwerkzeug bei der Bewegung an den Gegenstücken und den Formteilen keinen Verschleiß verursacht. Entsprechend kann auch ein Um formwerkzeug ausgebildet sein.The embodiment represents a molding tool 1. The core 2 of the molding tool 1 is provided with a hard layer 3 in the form of a nitride layer. A soft coating 4 is implanted under pressure onto or into the surface of the hard layer 3. Tungsten disulfide is applied or applied under pressure in powder form and adheres firmly to the hard layer. As a result, the wear protection provided by the hard layer remains fully effective. In addition, friction is reduced so that the molding tool does not cause wear when moving on the counterparts and the molded parts. A forming tool can also be designed accordingly.
