KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft einen zweiteiligen Kernträger für Gießereien, welcher die Erzielung einer dichten und gleichmäßigen Wandstärke ermöglicht.The invention relates to a two-part core support for foundries, which the achievement allows a dense and uniform wall thickness.
Er unterscheidet sich von Kernstützen ähnlicher Bauart dadurch, daß die breite Grundplatte des Bockes, welche eingeformt wird, durchbrochen ist, so daß der in die Durchbrechungen eingreifende Formsand ein ίο Verschieben der Kernstütze verhindert.It differs from core supports of a similar design in that the width Base plate of the block, which is molded in, is perforated so that the in the Openings encroaching molding sand prevents ίο shifting of the core support.
Ferner unterscheidet sich der Kernträger von anderen dadurch, daß der Schaft der Stützplatte doppelkegelförmige Gestalt hat, so daß etwa in seiner Mitte eine Einschnürung gebildet ist, welche ein dichtes Verstemmen und Verschweißen des fertigen Gußstückes mit der Kernstütze gewährleistet.Furthermore, the core carrier differs from others in that the shaft of the Support plate has a double conical shape, so that a constriction approximately in its center is formed, which a tight caulking and welding of the finished casting guaranteed with the core support.
In der Zeichnung stellen dar:In the drawing show:
Fig. ι und 2 zwei verschiedene Ausführungsformen des Kernträgers im Schnitt und Grundriß,Fig. Ι and 2 two different embodiments of the core girder in section and plan,
Fig. 3 ein Gußstück mit eingegossener Kernstütze mit dem wieder verwendbaren
Bock,
Fig. 4 und 5 die eingeformten Kernträger.3 shows a casting with a cast-in core support with the reusable bracket,
4 and 5 show the molded-in core supports.
Der Kernträger besteht aus zwei Teilen, aus dem Bock α oder c und der eigentlichen Kernstütze ds, b s. Der Bock c hat eine breite Grundplatte j>, welche bei D mehrmals durchbrochen ist; in diesem Bock ist die eigentliche Kernstütze, die aus dem doppelkegelförmigen Schaft b bezw. d mit der Stützplatte s besteht, eingesetzt oder eingeschraubt.The core support consists of two parts, the bracket α or c and the actual core support ds, b s. The bracket c has a wide base plate j>, which is perforated several times at D; in this block is the actual core support, which respectively from the double conical shaft b. d with the support plate s , inserted or screwed in.
Der Bock α bezw. c wird gleichzeitig mit dem Modell unter Abstützung gegen eine sogenannte Formkastentraverse t mit eingestampft (Fig. 4 und 5). Die Durchbrechungen D der Grundplatte jp haben den Zweck, eine ununterbrochene Formsandverbindung vor und hinter der Grundplatte ρ herzustellen und dadurch einem Verschieben des Kernträgers vorzubeugen. Ist die Form so weit hergerichtet, so steckt oder schraubt man die eigentliche Stütze b oder d mit der Tragplatte s in den Bock. Die Wandstärke w des 4-5 Rohres, also des Zwischenraumes zwischen innerer Formwand und Kernoberfiäche, kann durch Verstellen des Schaftes b oder d in dem Bock nach Belieben geregelt werden.The buck α respectively. c is tamped at the same time as the model with support against a so-called molding box traverse t (FIGS. 4 and 5). The openings D of the base plate jp have the purpose of producing an uninterrupted molding sand connection in front of and behind the base plate ρ and thereby prevent the core support from shifting. Once the shape has been prepared so far, the actual support b or d with the support plate s is inserted or screwed into the bracket. The wall thickness w of the 4-5 tube, i.e. the space between the inner mold wall and the core surface, can be regulated as desired by adjusting the shaft b or d in the bracket.
Der Schaft b oder d hat, wie bereits gesagt ist, eine doppelkegelförmige Gestalt, so daß er etwa in der Mitte eine Einschnürung aufweist. The shaft b or d has, as has already been said, a double-conical shape, so that it has a constriction approximately in the middle.
Hierdurch wird eine leichtere und innigere Verschmelzung der Stütze mit der Rohrwand w erzielt; auch erleichtert diese Einschnürung ein Verstemmen einer undichten Stelle der Rohrwand an der Kernstütze.This results in an easier and more intimate fusion of the support with the pipe wall w ; this constriction also makes it easier to caulk a leak in the pipe wall on the core support.
