Abstract

A casting mold for a crankcase of an internal combustion engine includes a water jacket core which has a frame core and a cooling duct core. A land core is provided which is designed and positioned in such a way as to form a cooling duct in an inter-cylinder land of a crankcase. The land core is retained in the frame core and is, or can be, centered using a top core.
