Abstract (en)
[origin: WO2018178762A1] 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 the invention 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 another in 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.
