Description

Kokille zum Gießen feinmaschiger Sammlergitter I?s ist bekannt, feinmaschige Sammlergitter ü, Kokillen zu gießen, in denen das Metall von einem parallel zur waagerecht liegenden Gitterfläche liegenden Gießraum aus senkrecht zur Fläche des Gitters einläuft. Dieses Verfahren hat bis jetzt praktisch keine große Bedeutung erlangt.Chill mold for casting fine-mesh collector grids I? S is known to be fine-meshed Collector grids ü to cast ingot molds, in which the metal of a parallel to horizontally lying grating surface lying casting space from perpendicular to the surface of the Lattice runs in. Up to now, this method has not been of great importance in practice attained.

Es ist weiterhin bekannt, feinmaschige Sammlergitter in Formen zu gießen, in denen bei senkrechter Anordnung der Gitterfläche die Formrillen der senkrechten Gitterstäbe bis zu der über die ganze Gitterbreite reichenden lingußöffnung selbst durchgeführt sind, so daß das flüssige Metall in allen Rillen gleichzeitig von oben herab herunterfällt. Es wurde festgestellt, daß bei diesem Gießverfahren nicht mit Sicherheit das Gitterfeld vollständig ausläuft, weil in den Kanälen oft Luft festgehalten wird, die nicht nach oben entweichen kann. Man hat auch zur Umgehung dieser Schwierigkeiten den Einguß vollständig von der Form für das Gitter getrennt und neben dein Rahmen einen bis zum Grund der Form reichenden besonderen Eingußtrichter angeordnet. Aus diesem Trichter tritt durch viele kleine seitliche Durchflüsse das Metall quer zur Eingußrichtung und zum Teil von unten in die Gitterform ein. Dieser Eingußtrichter kühlt jedoch das eingegossene Metall unnötig stark ab, so daß der bessere Luftauslaß durch ein schlechteres Auslaufen in Kauf genominen wird. Außerdem entstehen bei dieser Form sehr viel toter Guß und entsprechend hohe Umschinelzkosten.It is also known to use fine-mesh collector grids in shapes pour, in which, when the grid surface is arranged vertically, the grooves of the vertical Bars up to the casting opening itself, which extends over the entire width of the grid are carried out so that the liquid metal in all grooves simultaneously from above falls down. It was found that this casting process does not involve Safety the grid field runs out completely because air is often trapped in the ducts that cannot escape upwards. One also has to circumvent these difficulties the sprue completely separated from the mold for the grid and next to your frame arranged a special pouring funnel reaching to the bottom of the mold. the end The metal passes across the funnel through many small lateral passages Injection direction and partly from below into the grid shape. This sprue however cools the cast metal unnecessarily strong, so that the better air outlet is accepted by a worse leakage. In addition, arise at this form has a lot of dead cast and correspondingly high costs for shingling.

Man kennt ferner das Ausspritzen der Forin von Saininlergittern, bei der das Metall unter Druck sowohl in die Rahmenteile als auch in die Gitterstäbe von unten her eingedrückt wird. Das Spritzen ist aber in den seltensten Fällen wirtschaftlicher als (las Gie- ßen unter dein Druck des eigenen Gewichtes des Metalls. Gegenstand der vorliegenden Ertiiidtuig ist eine Kokille -7.111n Gießen feinmaschiger Sanini- lergitter, die von einem Rahmen st:irkeren Ouerschnitts umeben sind, welche dadurch gekennzeichnet ist, daß die Eingttßstelle aus-, schlielllich über dein einen der senkrechten Schenkel des Rabinenangeordnet ist. 1n der Zeichnung ist ein Ausfiilirtnigstxi- spiel einer Isol;ille veranschaulicht. die geniäP der I:rfindtuig ausgestaltet ist. Abb. 1 stellt eine geöffnete Kokille dar, d.11. eine Ansicht der Innenseite der einen FLilfte, Abb. 2 einen Querschnitt durch beide h()- killenhälften Eings II-1I in Abb. t. 1)1e beheizte Gießform besteht in bekannter Weise aus zwei Formhälften a und b, zcvi- sclien denen der Gnßrauni für das Gitter vor- gesehen ist. Das flüssige Metall wird von oben in den Einlauftricliter <I eingegossen, der über der senkrechten Rahmenseite e# liegt. Durch diesen senkrechten Rahmenschenkel fließt das flüssige Metall in den unteren Rahmenbalken und dringt von hier und von der Seite aus in die feinen und zahlreichen Gitterkan:ilchen ein. Die Luft wird durch den anderen senkrechten Rahmenschenkel c mit stciäender Füllung der Gußforni abgeleitet.We also know the injection of the form of Saininler grids, in which the metal is pressed under pressure into both the frame parts and the bars from below. But the splash is in the seldom more economical than (read Gie- eat under the pressure of your own weight of the metal. The subject of the present Ertiiidtuig is a mold -7.111n pouring fine-meshed sanini lattice that is supported by a frame Ouschnitts are umeben, which thereby is marked that the input point is finally over your one of the verticals Thigh of the rabbit is arranged. In the drawing is a filing game of an isol; illegally illustrated. the geniäP the I: is properly designed. Fig. 1 shows an open mold, d.11. a view of the inside of one of the fifths, Fig. 2 a cross section through both h () - Killenhälften Eings II-1I in Fig. t. 1) 1e heated mold consists of a known Way of two mold halves a and b, zcvi- slien in front of those of the greed for the lattice is seen. The liquid metal is from above poured into the enema tricliter <I, which over the vertical frame side e # lies. By this flows through this vertical frame leg liquid metal in the lower frame beam and penetrates from here and from the side into the fine and numerous lattice channels a. The air is discharged through the other vertical frame leg c with stciäender filling of the cast molds.
