Einzelheiten, Merkmale und Vorteil der Erfindung ergeben sich aus der nachstehenden Erläuterung eines in der Zeichnung schematisch dargestellten Ausführungsbeispieles.Details, features and advantages of the invention will be apparent from the following Explanation of an embodiment shown schematically in the drawing.

Die in der einzigen Figur perspektivisch mit einem Blick von oben dargestellten Spreizkokille 10 weist zwei als Stützrahmen ausgebildete und mit Kupferplatten 12, 13 armierte Breitseitenwände 2, 3 auf, zwischen welchen zwecks Formatbreiteneinstellung relativ zueinander verschiebbare Schmalseitenwände 4 einspannbar gehalten sind. Für deren Einspannung sind zwischen den Breitseitenwänden 2, 3 Kraftmittel vorgesehen, deren Spannweg oder Spannkraft einstellbar ist. Die Breitseitenwände und die Schmalseitenwände sind in an sich bekannter Weise gekühlt.Those shown in perspective in the single figure with a view from above Spreading mold 10 has two designed as a support frame and with copper plates 12, 13 reinforced broad side walls 2, 3, between which for format width adjustment Narrow side walls 4 which can be displaced relative to one another can be clamped are held. For their clamping between the broad side walls 2, 3 power means provided, the clamping path or clamping force is adjustable. The broad side walls and the narrow side walls are cooled in a manner known per se.

Üblicherweise ist die Spreizkokille 10 auch mit ihren die Kupferplatten 12, 13 tragenden Breitseitenwänden 2, 3 innerhalb eines zur Aufnahme der auf die Kokillenwände 2, 3, 4 einwirkenden Kräfte ausgebildeten formstabilen Außenrahmens 1 unter Ausbildung eines in sich geschlossenen Kräftesystems angeordnet.The expansion mold 10 is usually also used with the copper plates 12, 13 Broad side walls 2, 3 within one for receiving the mold walls 2, 3, 4 acting forces trained dimensionally stable outer frame 1 under training a self-contained force system.

Als Kraftmittel sind an jeder Breitseite 7 des Außenrahmens 1 vier die Breitseitenwände 2, 3, der Kokille 10 abstützbar angeordnete Hydraulikzylinder 5 befestigtThe broad side walls are four as power means on each broad side 7 of the outer frame 1 2, 3, the mold 10 is attached to a supportable hydraulic cylinder 5

Die Breitseiten 7 des Außenrahmens 1 sind nach der Lehre der Erfindung mit durch endständige Querträgerelemente 8 im Abstand parallel verbundenen Längsträgem 9 als Rechteckrahmen ausgebildet, wobei die Hydraulikzylinder 5 an den Querträgerelementen 8 angeordnet sind.The broad sides 7 of the outer frame 1 are with according to the teaching of the invention terminal cross member elements 8, longitudinally connected longitudinal beams 9 at a distance formed as a rectangular frame, the hydraulic cylinder 5 on the cross member elements 8 are arranged.

Weiterhin sind die Breitseiten 7 des Außenrahmens 1 durch quer dazu angeordnete Brückenelemente 11 miteinander zum in sich geschlossenen Außenrahmen 1 verbunden. Dabei sind die Einrichtungen 6 zur Verstellung der Kokillen-Schmalseitenwände 4 in den Brückenelementen 11 untergebracht, und zwar so, dass sie sich mit den Schmalseitenwände 4 in einer Linie befinden.

Infolge der erfindungsgemäßen Konstruktion des Außenrahmens 1, der die Kokille 10 allseitig umschließt, bleiben alle Kräfte, thermisch bedingte Kräfte oder Verstellkräfte, die innerhalb der Kokille auftreten, innerhalb des geschlossenen Kräftesystems des Außenrahmens 1; sie verursachen keine Reaktionskräfte nach außen. Dabei ist der Außenrahmen 1 so gestaltet, dass die Breitseitenwände 2, 3, die die Kupferplatten 12, 13 tragen, mittenzentriert sind, was dazu führt, dass bei thermischem Wachstum der Breitseitenwände 2, 3 und der Kupferplatten 12, 13 alle genannten Elemente sich relativ zum Außenrahmen symmetrisch ausdehnen, wobei die Kräfte, die von den Breitseitenwänden 2,3 bzw. den Schmalseitenwänden 4 der Kokille 10 auf den Außenrahmen 1 übertragen werden, auf ein Minimum reduziert sind.As a result of the inventive construction of the outer frame 1, the mold 10 encloses on all sides, all forces remain, thermally induced forces or adjusting forces, that occur within the mold, within the closed system of forces the outer frame 1; they do not cause external reaction forces. The outer frame 1 is designed so that the wide side walls 2, 3, the Wear copper plates 12, 13, are centered, which leads to thermal Growth of the broad side walls 2, 3 and the copper plates 12, 13 all mentioned Elements expand symmetrically relative to the outer frame, whereby the forces exerted by the broad side walls 2, 3 and the narrow side walls 4 of the Mold 10 are transferred to the outer frame 1, reduced to a minimum are.

Darüber hinaus läßt es die erfindungsgemäße Ausgestaltung des Außenrahmens 1 und seiner Breitseiten 7 in Form eines Rechteckrahmens zu, dass wahlweise mit großem Vorteil eine elektromagnetische Bremse oder ein elektromagnetischer Rührer installiert und diese dabei von außen durch den Rahmen 1 zwischen die Breitseitenwände 2, 3 eingefahren werden können.In addition, it allows the design of the outer frame 1 according to the invention and its broad sides 7 in the form of a rectangular frame that either with great advantage of an electromagnetic brake or an electromagnetic stirrer installed and this from the outside through the frame 1 between the broad side walls 2, 3 can be retracted.

Dabei ist es möglich, die Einrichtungen zur Verstellung der Schmalseitenwände an den Brückenelementen 11 des Außenrahmens 1 unterzubringen, und zwar so, dass sich diese mit den Schmalseitenwänden 4 in einer Flucht befinden, um das im System auftretende Spiel zu minimieren. It is possible to use the devices for adjusting the narrow side walls to accommodate the bridge elements 11 of the outer frame 1, in such a way that they are in alignment with the narrow side walls 4, around that in the system minimize occurring game.
