Casting core and method for the production thereof

The present invention relates to a casting core (1), which has the basic form of a hollow body, wherein the casting core (1) is formed from a moulding material which consists of a mixture that is formed from a moulding sand and a binder as well as optionally additives that are added to adjust its properties, and relates to a method for the production thereof. The casting core (1) according to theinvention can be produced in an easy way. This is achieved by the casting core (1) being divided into at least two subsegments (9-17) and by moulding elements (28a-30b) which interact with one anotherin a form-fitting manner and by means of which the subsegments (9-17) arranged adjacent to one another are fixed immovably with respect to one another, at least in one direction (LR.UR), by a form fit being provided at the peripheral sides with which subsegments (9-17) that are arranged adjacent to one another butt against one another, or being provided in the vicinity of these peripheral sides. 本发明涉及一种铸造型芯(1)，该铸造型芯具有空心体的
