Die Erfindung betrifft eine aus einem Steg mit stirnseitig angesetzten Tragelemente bestehende Kernstütze aus Blech für offene Wassermantelkerne, einer Form zum Gießen von Motorengehäusen. Die Tragelemente sind mit dem Steg verzapft .The invention relates to a core support made of sheet metal consisting of a web with supporting elements attached to the front for open water jacket cores, a mold for casting engine housings. The supporting elements are mortised to the web .
Beim Gießen von Motorengehäusen wird der künftige Kühlwasserraum während des Gießvorganges durch einen Formkern ausgefüllt. Ist der Formkern zwischen den Kerneinsätzen für die Zylinder durchbrochen, um einen kompakt bauenden Motor zu erhalten, müssen an diesen Stellen vor dem Guß Kernstützen gesetzt werden, welche das Aufschwimmen der Kernteile während des Gießens verhindern. Diese Kernstützen müssen die Kernteile kräftig verspannen, ohne sie jedoch zu beschädigen .When casting engine housings, the future cooling water space is filled with a mold core during the casting process. If the mold core is broken through between the core inserts for the cylinders in order to obtain a compact engine, core supports must be placed at these points before casting to prevent the core parts from floating during casting. These core supports must firmly brace the core parts without damaging them.
Diese Aufgabe wird durch eine konische Wassermantelkernstütze, wie unter G8700594.B bekannt, bereits gelöst, wobei durch die Keilwirkung auch eine recht gute Verspannung erreicht wird.This task is already solved by a conical water jacket core support, as known under G8700594.B, whereby the wedge effect also achieves quite good bracing.
Ist die Wassermantelkernstütze in unmittelbarer Nähe des Eingußtrichters angeordnet, kann es vorkommen, daß sich durch die hohe Temperatur der Schmelze die Schweißverbindungen der Wassermantelkernstütze lösen und somit die Stützwirkung verlorengeht. Auch bei hoher Gießtemperatur kann dieser Vorgang eintreten.If the water jacket core support is located in the immediate vicinity of the pouring funnel, it can happen that the welded joints of the water jacket core support come loose due to the high temperature of the melt and thus the supporting effect is lost. This process can also occur at high pouring temperatures.

Erfindungsgemäß wird daher vorgeschlagen, Tragelemente und Mittelsteg miteinander zu verzapfen. Die konkav gebogenen Stützbleche weisen rechteckige Ausnehmungen auf. In diese Ausnehmungen ragen die zapfenförmigen Ausbildungen des Mittelsteges. Selbst wenn die Schweißverbindungen durch die Schmelze gelöst werden, verhindert die Verzapfung Verschiebungen des Steges bzw. der Stützbleche .According to the invention, it is therefore proposed that the supporting elements and the central web be mortised together. The concavely curved support plates have rectangular recesses. The pin-shaped formations of the central web protrude into these recesses. Even if the welded connections are released by the melt, the mortising prevents the web or the support plates from shifting.
Die Wassermantelkernspange ist in der Figur schematisch dargestellt. Die kürzeren Kanten (2) des trapezförmigen Bleches (1) sind zapfenförmig ausgebildet (5). Diese Zapfen passen in die rechteckigen Ausnehmungen (4) der Tragelemente in Form konkav gebogener Stützbleche (3). Trapezförmiges Blech (1) und Stützbleche (3) sind miteinander verschweißt.The water jacket core clamp is shown schematically in the figure. The shorter edges (2) of the trapezoidal sheet (1) are designed in the shape of a tenon (5). These tenons fit into the rectangular recesses (4) of the support elements in the form of concavely bent support plates (3). The trapezoidal sheet (1) and support plates (3) are welded together.
