Description
Verfahren zum Ausgiessen von geschlossenen Giessformen und Einrichtung zur Durehfühw dieses Verfahrens
Beim Ausgiessen von geschlossenen Giess- formen mit warmflüssigem Metall, Glas oder Kunststoff ist es zur Erzielnng einwand- freier lunkerfreier Formstüeke sehr wichtig, dal der Formholilraum vollständig mit dem (aiessmatenial ausgefüllt wird'und dass keine (taKsblasen in der Giessmasse bleiben können.
Dieses Ziel ist besonders mit zähflüssigem Giessmaterial schwer zu erreichen.
Naeh der vorliegenden. Erfindung kenn- zeiehnet sich ein Verfahren zum Ausgiessen von geschlossenen Giessformen mit warmflüssigem Metall, Glas oder Kunststoff da dureh, dass die in die Form eingegossene Giessmasse, solange sie noeh flüssig ist, sowohl einer Vibrations-als auch einer Presswir kung ausgesetzt wird.
Eine Giesseinrichtung zur Durchführung dieses Verfahrens ist erfindungsgemäss ge kennzeichnet durch eine geschlossene Giess- form, Mittel zum Zuführen von flüssiger Giessmasse in den. Formhohlraum sowie durch Mittel, um die in die Form eingefüllte Giessmasse einer Vibrations-und einer Presswir- kung auszusetzen.
Ausführungsbeispiele solcher Einriehtung sind in der Zeichnung dargestellt.
In Fig. 1 ist mit 1 ein Formblock bezeich- net, der einen Formhohlraum 2 enthält, welcher über den Zufuhrkanal 3 und die Steigkanäle 4 mit Giessmasse gefüllt werden soll.
Der Zufuhrkanal 3 führt von oben durch den Formblock an die Unterseite des Formhohlraumes bzw. der Steigkanäle. Ausserdem führt von aussen ein zylindriseher Kanal 5 in horizontaler Richtung zur, Unterseite des Formhohlraumes, das heisst der Einfuhrkanal 3 und der genannte zusätzliche Kanal 6 vereinigen sich miteinander. In diesem Kanal 5 ist ein passender Kolben 6 von einer Welle 7 aus verschiebbar ; sein äusseres Ende ist me chanisch mit einem schematisch gezeichneten Vibrator 8 verbunden.
Beim Einfüllen der Giessmasse durch die Leitung 3 wird der Kolben 6 der Vibrationswirkung des Vibrators 8 ausgesetzt.
Die Vibration des Kolbens überträgt sich auf die warmflüssige'Giessmasse, so dass die Giessmasse in die feinsten Formverzweigun- gen eindringt. Wenn nachher der Kolben 6 über die Welle 7 auch noch nach links verschoben wird, bewirkt diese Zusammenpres- sung der im Giesshohlraum eingeschlossenen Giessmasse eine weitere Verdichtung der Giessmasse im Giesshohlraum. Auf diese Weise lassen sich einwandfreie Gusskörper herstellen.
Bei der Variante nach Fig. 3 ist der Vibrator 8 mit einer Vibriernadel 6a verbmden, die in einem besonderen Kanal 5a eingebaut ist, der sich mit dem Einfuhrkanal 3 und dem Presskanal 5b, in welchem der Prf. esskol- ben 6b versehiebbar ist, an der Unterseite des Formhohlraumes 2 vereinigt Aueh hier wird die Giessmasse beim Eingiessen zuerst durch die Vibriernadlel 6a einer Vibrationswirkung und nachher durch den Presskolben 6b einer Presswirkung ausgesetzt.
Method for pouring closed casting molds and device for performing this method
When pouring closed casting molds with hot metal, glass or plastic, it is very important to achieve perfect, void-free molded parts that the mold cavity is completely filled with the (material) and that no (hot-fluid bubbles can remain in the casting compound.
This goal is particularly difficult to achieve with viscous casting material.
Near the present. The invention is characterized by a method for pouring closed casting molds with hot metal, glass or plastic because the casting compound poured into the mold is exposed to both a vibration and a pressing effect while it is still liquid.
A casting device for performing this method is characterized according to the invention by a closed casting mold, means for supplying liquid casting compound into the. Mold cavity and means for subjecting the casting compound filled into the mold to a vibration and a pressing action.
Embodiments of such Einriehtung are shown in the drawing.
In FIG. 1, 1 denotes a mold block which contains a mold cavity 2 which is to be filled with casting compound via the supply channel 3 and the riser channels 4.
The supply channel 3 leads from above through the mold block to the underside of the mold cavity or the riser channels. In addition, a cylindrical channel 5 leads from the outside in the horizontal direction to the underside of the mold cavity, that is to say the inlet channel 3 and the named additional channel 6 combine with one another. In this channel 5, a suitable piston 6 can be displaced from a shaft 7; its outer end is mechanically connected to a vibrator 8 shown schematically.
When pouring the casting compound through the line 3, the piston 6 is exposed to the vibrating effect of the vibrator 8.
The vibration of the piston is transmitted to the warm liquid casting compound, so that the casting compound penetrates into the finest branches in the mold. If afterwards the piston 6 is also shifted to the left via the shaft 7, this compression of the casting compound enclosed in the casting cavity causes a further compression of the casting compound in the casting cavity. In this way, flawless cast bodies can be produced.
In the variant according to FIG. 3, the vibrator 8 is connected to a vibrating needle 6a, which is built into a special channel 5a, which connects to the inlet channel 3 and the press channel 5b, in which the test piston 6b can be displaced the underside of the mold cavity 2 combined. Also here the casting compound is subjected to a vibration effect during pouring first by the vibrating needle 6a and then by the plunger 6b to a pressing effect.
