Description

Die in den Gießereien zur Verwendung kommenden üblichen Kernstützen werden nach feststehenden Höhenmaßen ι ο, 12, 14, 16, 18, 20 mm usw. bis 80 mm Höhe hergestellt. Diese feststehenden Maße bedingen erstens einen großen Vorrat an Kernstützen, zweitens geht bei Aussuchung der jeweils passenden Kernstützen sehr viel Zeit verloren, drittens werden sehr viele Kernstützen durch das Nichtpassen achtlos beiseitegelegt und gehen dann zugrunde. Es sind nun schon verschiedene Vorschläge gemacht, um die Höhenmaße der Stützen verändern zu können, teils durch keilförmig zueinander passende Schrägflächen, teils gegossene, mit Schrauben versehene, jedoch einschenklige Stützen. Das erstgenannte Muster ist nur in senkrechter Anwendung einwandfrei, weil es nur so zwischen Kern und Form eingekeilt werden kann. Bei waagerechter Anwendung ist die Brauchbarkeit in Frage gestellt, weil schon bei der geringsten ungleichen Berührung der oben aufgelegten Stützen durch den Kern oder die Form ein Verrücken stattfindet, welches dann beim fertigen Gußstück durch ungleiche Wandstärke zum Ausdruck kommt oder zum Ausschuß führt. Die eingeführten verschraubbaren Guß stützen können nur einschenklig ausgeführt werden, sind aber wegen ihres schlechten Einschweißens im Gußstück kaum zu gebrauchen.The usual core supports that are used in the foundries according to fixed height dimensions ι ο, 12, 14, 16, 18, 20 mm etc. up to 80 mm in height. These fixed dimensions firstly require a large supply of core supports, secondly, a lot of time is lost in the search for the appropriate core supports, and thirdly, a large number of core supports are required carelessly put aside by not fitting and then perish. It is already made various suggestions to be able to change the height dimensions of the supports, partly by wedge-shaped matching sloping surfaces, partly cast, with Screwed, but one-legged supports. The former pattern is only in vertical application, because it is wedged between the core and the mold can be. When used horizontally, the usefulness is called into question because at the slightest unequal contact with the supports placed above by the Core or the mold a shift takes place, which then takes place in the finished casting is expressed by unequal wall thickness or leads to scrap. Can support the imported screwable cast are only made with one leg, but are because of their poor welding hardly usable in the casting.

Die Stütze gemäß der Erfindung, die in Abb. ι bis 3 in Ansicht und Draufsicht dargestellt ist, unterscheidet sich von den bekannten Stützen ganz wesentlich schon dadurch, daß der auf der unteren Stützplatte angeschweißte 8 mm starke Keilsteg verzahnt ist, und zwar so, daß jeder Zahn 1 mm höher liegt als der vorhergehende. Die obere Stützplatte c ist mit je zwei 16111m breiten und verschieden langen Schenkeln & versehen, welche in die verzahnte Keilleiste zahnförmig eingreifen. Die Schenkel end en werden unten ausgeklinkt, so daß links und rechts von der verzahnten Leiste α zwei vorstehende Nasen d, d' als Führung dienen und gleichzeitig ein Umkippen der oberen' Stützenhälfte verhindern. The support according to the invention, which is shown in Fig. Ι to 3 in view and plan view, differs from the known supports quite significantly in that the 8 mm thick wedge web welded to the lower support plate is toothed, in such a way that each tooth is 1 mm higher than the previous one. The upper support plate c is provided with two legs 16111m wide and of different lengths, which engage in the toothed V-ledge. The leg ends are notched at the bottom so that to the left and right of the toothed bar α two protruding lugs d, d ' serve as a guide and at the same time prevent the upper half of the support from tipping over.
