Description
<Desc/Clms Page number 1>
Kernstück für Stereotypplatten-Giessformen.
Den Gegenstand der Erfindung bildet ein Kernstück für Stereotypplattengiessformen, bei dem die die Rückwand der Stereotypplatte formende Wand aus einem Metall besteht, dessen Wärmeleitfähigkeit wenigstens derjenigen von Aluminium gleich ist.
Der Vorteil dieser Einrichtung besteht darin, dass, wie die Erfahrung gezeigt hat, ein besseres Ausfüllen aller Feinheiten der Matrizen eintritt, während das Kühlen der gegossenen Platte unter Einwirkung des Kühlwassers im Kernstück schneller stattfindet.
Auf der Zeichnung stellen dar : Fig. 1 einen Längsschnitt und Fig. 2 einen Querschnitt durch ein Ausführungsbeispiel eines Kernstückes nach der Erfindung.
Die auf den Gussteil a des Kernstückes aufgesetzte Wand b besitzt seitlich je eine unterschnittene Leiste e, die mit einem entsprechend gestalteten Teil des Gussteiles in Eingriff steht. An den Enden kann die Verbindung noch durch Schweissen weiter gesichert werden. Die Platte ist aussen mit Nuten zur Erzeugung der Rippen an der Rückseite der Stereotypplatten und innen mit Kühlrippen versehen, welche ein schnelleres Kühlen der gegossenen Platte zu dem Zwecke herbeiführen, einen durchaus gesunden Guss zu sichern. Zu dem gleichen Zwecke wird die Wand b aus einem die Wärme gut leitenden Metall, wie Aluminium, Kupfer usw., hergestellt, während der übrige Kernteil a aus beliebigem Metallguss besteht.

Core piece for stereotype plate casting molds.
The subject matter of the invention is a core piece for stereotype plate casting molds in which the wall forming the rear wall of the stereotype plate consists of a metal whose thermal conductivity is at least equal to that of aluminum.
The advantage of this device is that, as experience has shown, better filling of all the subtleties of the dies occurs, while the cooling of the cast plate under the action of the cooling water in the core takes place more quickly.
The drawing shows: FIG. 1 a longitudinal section and FIG. 2 a cross section through an embodiment of a core piece according to the invention.
The wall b placed on the cast part a of the core piece has an undercut strip e on each side, which engages with a correspondingly shaped part of the cast part. At the ends, the connection can be further secured by welding. The plate is provided with grooves on the outside for producing the ribs on the back of the stereotype plates and on the inside with cooling ribs, which bring about faster cooling of the cast plate for the purpose of ensuring a thoroughly healthy cast. For the same purpose, the wall b is made of a metal that conducts heat well, such as aluminum, copper, etc., while the rest of the core part a consists of any metal casting.
