Abstract

Mould coated with a hard layer has a soft coating implanted in the hard layer by means of applied pressure. The soft coating comprises tungsten disulphide. In an example, the mould (1) comprises a core (2) coated with a hard nitride layer (3). Tungsten disulphide powder is sprinkled onto the hard layer surface, and then implanted into it by means of pressure applied.

Description

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

Unter einem Formwerkzeug oder Umformwerkzeug wird ein Spritzgießwerkzeug, ein Preßwerk­ zeug, 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.Under a mold or forming tool is an injection mold, a press stuff, a drawing tool, a punching tool or the like understood. A hard layer in the form of a Nitride layer is applied in the arc and serves to protect against wear. In many cases the movement of the tools desires a sliding or smearing effect that passes through the hard layer is prevented.

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 Weichbe­ schichtung unter Druck implantiert ist.This object is achieved according to the invention in that a soft tissue on the hard layer layered under pressure.

Die Erfindung unterscheidet sich insofern vom Stand der Technik, als die Weichbeschichtung den Reibbeiwert verringert und einen schmierungsfreien Lauf sicherstellt.The invention differs from the prior art in that the soft coating Coefficient of friction reduced and lubrication-free running ensured.

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

Ein Ausführungsbeispiel der Erfindung wird anhand der Schemazeichnung erläutert.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 Weichbeschich­ tung 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 Ver­ schleißschutz 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 verur­ sacht. Entsprechend kann auch ein Umformwerkzeug ausgebildet sein.The exemplary embodiment represents a mold 1. The core 2 of the mold 1 is provided with a hard layer 3 in the form of a nitride layer. On the hard layer 3 , a soft coating device 4 is implanted under pressure on or in the surface. Tungsten disulfide is applied or applied in powder form under pressure and adheres firmly to the hard layer. As a result, wear protection through the hard layer remains fully effective. In addition, the friction is reduced so that the tool does not cause wear when moving on the counterparts and the molded parts. A forming tool can also be designed accordingly.
