Description

Die vorliegende Erfindung betrifft eine Kernstütze bestehend aus einem runden oder rechteckigen Haltesteg (1), in profilierter oder glatter Form mit einer angenieteten oder angeschweissten, gelochten oder ungelochten halbschalenförmige, mit oder ohne Fase versehenen Aufnahme (2).The present invention relates to a core support consisting of a round or rectangular holding web ( 1 ), in profiled or smooth form, with a riveted or welded, perforated or perforated shell-shaped, bevelled or chamfered receptacle ( 2 ).

Kernstützen sind aus dem Stand der Technik hinreichend bekannt. Solche Kernstützen dienen schlussendlich dazu, in einer Gußform während des Gießvorganges, die Gußkerne in einer bestimmten Position zu halten. Das heißt bei z.B. der Herstellung von hohlen Nockenwellen für Motoren gibt es unterschiedlich konstruierte Gußkerne, die aus Kernsand gepresst oder Glasstäbe bestehen können. Die Kerne müssen in der Gießform genau zentriert und stabil in ihrer Lage gehalten werden. Das erreicht man durch Setzen von Kernstützen, die, der geforderten Gußwandstärke entsprechend, Kerne und Form auf Abstand halten. Nach dem Gießvorgang müssen die Kernstützen mit dem Gußwerkstoff, fest und dicht eingeschweißt, eine Einheit bilden.Nuclear supports are Well known from the prior art. Such core supports ultimately serve in addition, in a mold while the casting process, the casting cores to hold in a certain position. That is at e.g. the production of hollow camshafts for Engines have differently constructed cast cores pressed from core sand or glass rods can exist. The cores need in the mold exactly centered and stable in their position. That achieved by placing core posts, the according to the required cast wall thickness, Keep cores and shape at a distance. After casting, the core supports must the casting material, firmly and tightly welded, form a unit.

Neu und erfindungsgemäß an diesen Kernstützen ist die Formgebung des Stahlblechringes (2), die ein clipartiges oder klemmartiges Aufstecken der Kernstütze radial zur Kernachse ermöglicht. Hierdurch ergibt sich der Vorteil, dass die Kernstütze an dem separaten Kernstab formgenau befestigt werden kann, der dann, an der gewünschten Position mit Kernstützen bestückt, in die äußere Gießform eingelegt wird und das solch eine Kernstütze als Nockenwellenkernstütze engesetzt wird.New and inventively on these core supports is the shape of the steel sheet ring ( 2 ), which allows a clip-like or clamp-like attachment of the core support radially to the core axis. This results in the advantage that the core support can be attached to the separate core rod dimensionally accurate, which is then loaded at the desired position with core supports, is inserted into the outer mold and that such a core support is used as camshaft core support.
