Abstract

Es sind Kühlmittelmantelkerne (16) zur Herstellung eines Zylinderkurbelgehäuses (10) mit schmaler Stegbreite mit mindestens einem einteiligen Grundkern (20), der mindestens zwei nebeneinander angeordneten im Wesentlichen hohlzylinderschnittförmige Kernkörper (22) aufweist, wobei jeweils die beiden nebeneinander angeordneten Kernkörper (22) eine gemeinsame axial verlaufende Schnittebene (24) aufweisen, die eine Verbindungsfläche (25) zwischen radialen Enden (26) der nebeneinander liegenden Kernkörper (22) bildet und einem Steckern (18), der die gegenüberliegenden radialen Enden (26) jedes Kernkörpers (22) in der Schnittebene (24) miteinander verbindet, bekannt.
Um eine Kühlung des Zylinders über seine gesamte Höhe und seinen gesamten Umfang sicherzustellen wird vorgeschlagen, dass der Stegkern (18) mehrere axial übereinander angeordnete entfernbare Einzelstegkerne (30) aufweist, die an den in der Schnittebene (24) angeordneten gegenüberliegenden radialen Enden (26) der Kernkörper (22) am Grundkern (20) befestigt sind.
