Description
Die Erfindung betrifft ein Verfahren zum reproduzierbaren Herstellen von insbesondere Oberflächenmustern in Einsatzplatten von Spritz- oder Druckgußwerkzeugen. The invention relates to a method for the reproducible production of, in particular, surface patterns in insert plates of injection or die casting tools.
Es ist bekannt Oberflächenmuster von Einsatzplatten, z. B. für Spritzgußwerkzeuge durch mechanische Bearbeitung derselben herzustellen. Diese Art der Herstellung hat jedoch einen hohen Fertigungsaufwand zur Voraussetzung. Außerdem benötigen aus einer großen Anzahl Bauteile hergestellte Erzeugnisse, z. B. aus mosaikartig zusammengefügten Bausteinen gebildete Schalttafelfelder, den gleichzeitigen Einsatz mehrerer Spritzwerkzeuge. Trotz sorgfältig angestrebter Übereinstimmung bei der Herstellung der Einsatzplatten für diese Spritzwerkzeuge sind Oberflächenabweichungen der Formteile vielfach unvermeidbar, die das Gesamtbild der Schalttafelanlage stören.It is known surface patterns of insert panels, e.g. B. for injection molding tools by mechanical processing to produce the same. However, this type of production has a high manufacturing cost Pre-condition. In addition, products made from a large number of components, e.g. B. from mosaic-like Switchboard panels formed from assembled modules, the simultaneous use of several Injection molds. Despite careful consistency in the manufacture of the insert plates for these injection molds, surface deviations of the molded parts are often unavoidable, which affect the overall picture disturb the switchboard system.
Die Erfindung hat zur Aufgabe identische Oberflächenmuster an einer beliebigen Anzahl Einsatzplatten reproduzierbar mit geringem Fertigungsaufwand zu schaffen.The invention has for its object identical surface patterns on any number of insert plates to create reproducible with little manufacturing effort.
Gemäß den Verfahrensschritten der Erfindung ist dies erreicht dadurch, daß ein Stahleinsatz mechanisch mit einem Negativ des Oberflächenmusters versehen, danach gehärtet und nachfolgend zur Bildung eines Oberflächenmusterpositivs in ein Kupfergesenk o. dgl. eingepreßt wird und daß mit dem Kupfergesenk als Elektrode Stahleinsätze mit der Negativform des Oberflächenmusters erodiert werden. Zweckmäßig kann als Kupfergesenk ein Stahlstempel mit einer Kupferauflage geeigneter Dicke, beispielsweise einer mehrere Millimeter starken Kupferplatte, dienen. Auf diese Weise sind beliebig viele Einsatzplatten mit identischen Oberflächenmustern von einem einzigen Stahleinsatz mit geringern Aufwand herstellbar. Das Kupfergesenk erlaubt dabei auch in weit auseinanderliegenden Zeitabschnitten die Nachlieferung identischer Stahleinsätze. Darüber hinaus weisen die Stahleinsätze mit erodiertem Oberflächenmuster in den Erodierflächen kraterhafte Absetzungen auf, die im Gegensatz zu mechanisch punzierten Oberflächenmustern zu einem leicht mattierten Gesamteindruck der Oberflächenmuster und damit zu Hierzu 1 Blatt ZeichnungenAccording to the method steps of the invention, this is achieved in that a steel insert mechanically provided with a negative of the surface pattern, then hardened and subsequently to form one Surface pattern positive in a copper die o. The like. Is pressed and that with the copper die as Electrode steel inserts are eroded with the negative shape of the surface pattern. Appropriately can be used as Copper die a steel stamp with a copper layer of suitable thickness, for example one several millimeters strong copper plate, serve. In this way, there are any number of insert panels with identical surface patterns can be produced from a single steel insert with little effort. The copper die allowed At the same time, the subsequent delivery of identical steel inserts in widely spaced periods of time. About that In addition, the steel inserts with the eroded surface pattern in the eroded areas have crater-like properties Deposits, which in contrast to mechanically hallmarked surface patterns to a slightly matted Overall impression of the surface pattern and therefore 1 sheet of drawings
