Description
Die Erfindung betrifft ein Verfahren zum Gießen von Kolbenringen, insbesondere aus Grauguß, und hat die gleichzeitige Herstellung mehrerer Kolbenringe in einem Gießvorgang zum Ziel. Dieses Ziel wird erfindungsgemäß dadurch erreicht, daß zwei oder mehr Kolbenringe verschiedener Größe ineinander angeordnet über einen die eingeformten Ringe verbindenden Gießkanal zu gleicher Zeit gegossen werden. Erfindungsgemäß können auch mehrere Formhohlräume mit in konzentrischer Anordnung eingeformten Ringen übereinander angeordnet und durch einen gemeinsamen Gießkanal zu gleicher Zeit gegossen werden. Statt übereinander können auch mehrere Formhohlräume in an sich bekannter Weise um einen zentralen Gießkanal leerumliegend angeordnet werden.The invention relates to a method for casting piston rings, in particular made of gray cast iron, and has the simultaneous production of several piston rings in one casting process to the goal. According to the invention, this aim is achieved by that two or more piston rings of different sizes arranged one inside the other over one the pouring channel connecting the molded rings are cast at the same time. According to the invention, several mold cavities can also be arranged in a concentric arrangement molded rings arranged one above the other and through a common pouring channel be poured at the same time. Instead of one above the other, several mold cavities can also be used arranged in a manner known per se around a central pouring channel so as to be empty will.
Die Erfindung wird an Hand der Zeichnung nachfolgend näher erläutert.The invention is explained in more detail below with reference to the drawing.
Fig. i der Zeichnung gibt eine Sicht von oben auf eine Gießform zur Ausführung des Verfahrens der Erfindung in beispielsweiser Ausführung wieder. In Fig. 2 sind drei übereinander angeordnete Formhohlräume dargestellt.Fig. I of the drawing gives a top view of a casting mold Execution of the method of the invention in an exemplary embodiment again. In Fig. 2 shows three mold cavities arranged one above the other.
Die in Fig. i dargestellte Gießform weist erfindungsgemäß zwei eingeformte konzentrisch ineinander angeordnete Ringe i und 2 auf, die durch einen Gießkanal 3 miteinander verbunden slin(d. q. ist der Ei.nguß. Mit 5 und. 6 :sind eingeformte Vertiefungen zur Aufnahme vorn Lunkerköpfe.n bezeichnet. Zur weiteren Erhöhung der Wirtschaftlichkeit können auch mehrere Formhohlkörper um den Einguß q. in Kreise angeordnet werden, oder es können, wie dies aus Fig. 2 ersichtlich .ist, zwei, drei und mehr Formhohlräume übereinander zur Anwendung kommen. Die Eingüsse q. bilden in diesem Falle einen durchgehenden Kanal, von dem das Gießmetall über die Anschlüsse 7 in die einzelnen Formhohlräume eintritt.According to the invention, the casting mold shown in FIG concentrically arranged rings i and 2, which are passed through a pouring channel 3 connected to each other slin (i.e. the cast iron. With 5 and. 6: are molded-in Marked depressions for receiving the hollow heads in the front. To further increase the Economy can also have several hollow moldings around the sprue q. in circles be arranged, or, as can be seen from Fig. 2 .ist, two, three and more mold cavities are used one above the other. The sprues q. form in this case a continuous channel, from which the casting metal over the connections 7 enters the individual mold cavities.
