nachdem das Metall eingegossen : und so weit erhärtet ist, dass ee, seine Gestalt beibehält indem ihre verschiedenen Teile auseinandergezogen werden. Das Gussstück kann sich frei dehnen und geht nach der Abkühlung auf das gewünschte Mass zurück.
Fig. 1 ist ein Grundriss der geschlossenen Form, Fig. 2 eine Stirnansicht derselben, Fig. 3 ist ein Aufriss von links in Fig. 2 gesehen, Fig. 4 ist ein Grundriss der offenen Form.
C (Fig. 4) bezeichnet das fertige Gussstück. Die Form besteht aus einer Grundplatte 1, beweglichen Seitenstücken 2,2, beweglichen Stirnstücken 3, 3 und beweglichen Kopfplatten 4, 4.
EMI2.1
Vor dem Giessen werden die Formenteile auseinander genommen, die Kerne eingesetzt und die Innenteile der Form mit dem erwähnten Anstrich überzogen. Dann wird die Form zusammengeschoben, durch Anziehen der Schrauben befestigt und das Metall bei 13 eingegossen, bis es bei 14 emporsteigt. Nachdem das Metall genügend erhärtet ist, um seine Form beizubehalten, wird die Gussform geöffnet. 20 Sekunden, bei grösseren Gussstücken entsprechend mehr, werden zur Erhärtung genügen. Diese Zeit kann man benutzen, um das Öffnen der Form vorzubereiten, indem man zunächst die beiden Teile der Kopfplatte 4 öffnet und dann mittelst der zugehörigen Schrauben die Seiten-und Stirnstücke 2 und 3 zurückzieht, so dass die Teile in die Stellung nach Fig. 4 gelangen.
Das Gussstück ist jetzt gänzlich frei von Druck, es dehnt sich aus und nimmt dann durch Schwindung die gewünschte Form und Mass ein.

after the metal is poured in: and has hardened so far that ee, maintains its shape by pulling its various parts apart. The casting can expand freely and returns to the desired size after cooling.
Fig. 1 is a plan view of the closed mold, Fig. 2 is an end view of the same, Fig. 3 is an elevation view from the left in Fig. 2, Fig. 4 is a plan view of the open mold.
C (Fig. 4) denotes the finished casting. The mold consists of a base plate 1, movable side pieces 2, 2, movable end pieces 3, 3 and movable head plates 4, 4.
EMI2.1
Before casting, the mold parts are taken apart, the cores are inserted and the inner parts of the mold are coated with the paint mentioned. Then the mold is pushed together, fastened by tightening the screws and the metal is poured in at 13 until it rises at 14. After the metal has hardened enough to hold its shape, the mold is opened. 20 seconds, or correspondingly longer for larger castings, will be sufficient for hardening. This time can be used to prepare for opening the mold by first opening the two parts of the head plate 4 and then using the associated screws to pull back the side and end pieces 2 and 3 so that the parts are in the position according to FIG reach.
The casting is now completely free of pressure, it expands and then takes on the desired shape and dimensions through shrinkage.
