Description

Das Einbringen des Formstoffes oder Formsandes in den Formkasten mittels Preßluft ist bekannt. Entweder benutzte man dabei mehrteilige Modelle und Sandformen, oder hohle, einteilige Sandformen wurden so hergestellt, daß man aus schmelzbarem Werkstoff erzeugte Modelle in Formkasten mit durch Preßluft eingeführten Formsand dicht umhüllt hat. Das Modell mußte dann herausgeschmolzen werden.The introduction of the molding material or sand into the molding box by means of compressed air is known. Either you used multi-part models and sand molds, or Hollow, one-piece sand molds were made from fusible material has produced models in the molding box tightly encased with molding sand introduced by compressed air. The model then had to be melted out will.

Die Erfindung bezweckt, die Herstellung von hohlen Sandformen für die Gießerei dadurch zu vereinfachen, daß die einzelnen Teile der hohlen Sandform ohne eigentliche Modelle in Hilfekästen hergestellt werden, die im wesentlichen aus der entsprechenden Formkastenwand und einer ihrem Sandformteile entsprechenden Modellwand bestehen. In diese Hilfskasten wird der Formstoff bzw. Formsand in bekannter Weise mittels Preßluft eingebracht, so daß nach Entfernen der Modellwand der Formstoff an der Formkastenwand anhaftet. Durch Zusammensetzen dieser Formkastenwände wird die hohle Sandform gebildet.The invention aims to thereby produce hollow sand molds for the foundry to simplify that the individual parts of the hollow sand mold without actual models are made in aid boxes, which essentially consist of the corresponding molding box wall and a model wall corresponding to their sand mold parts. In this auxiliary box is the molding material or molding sand in a known manner by means of compressed air introduced so that after removing the model wall, the molding material on the molding box wall adheres. By assembling these flask walls, the hollow sand mold becomes educated.

In der Zeichnung ist ein Ausführungsbeispiel einer nach vorliegendem Verfahren hergestellten Guß form dargestellt.The drawing shows an exemplary embodiment of one produced according to the present method Casting form shown.

Abb. ι zeigt die Formkastenwand r und die Modellwand 2 zur Bildung eines Formhilfskastens, dessen Hohlraum den einen Formteil 3 bestimmt, der durch Einbringen des Formstoff as. mittels Preßluft gebildet wird.Fig. Ι shows the molding box wall r and the model wall 2 to form an auxiliary molding box, the cavity of which determines the one molded part 3 which is formed by introducing the molding material as. By means of compressed air.

Er haftet an der Formkastenwand 1 an, so daß er nach Entfernen der Modellwand 2 freiliegt,He adheres to the molding box wall 1, so that it is exposed after removing the model wall 2,

Abb. 2 zeigt den Formhilfskasten zur Bildung des zweiten Formteiles 3'. Der Formhilf skasten besteht in analoger Weise aus der Formkastenwand 1' und der Modell wand 2'. Ein Aufsatzstück 4 ist zum Zwecke der Bildung des Eingusses 5 im Formteil 3' vorgesehen. Der Formteil 3' wird ebenfalls durch Einbringen des Formstoffes mittels Preßluft hergestellt und nach Entfernen der Modellwand 2' freigelegt.Fig. 2 shows the auxiliary mold box for forming the second molded part 3 '. The form aid Skasten consists in an analogous manner of the molding box wall 1 'and the model wall 2'. A top piece 4 is provided for the purpose of forming the sprue 5 in the molded part 3 '. The molded part 3 'is also produced by introducing the molding material by means of compressed air and after removing the Model wall 2 'exposed.

Die so gebildeten Formteile werden gemäß Abb. 3 zusammengesetzt, um das Gußstück 6 herstellen zu können.The molded parts thus formed are put together as shown in Fig. 3 to form the casting 6 to be able to produce.
