Abstract: A mold assembly for producing a casting core for a cooling jacket of an electric motor has an external mold and an internal mold enclosed by the external mold. The external mold forms an outer wall and the internal mold an inner wall of the core molding cavity fillable with a core material and having a cylindrical shape. The internal mold has two first mold shells and two second mold shells. The two first mold shells and the two second mold shells jointly form the inner wall of the core molding cavity. The second mold shells are arranged between the first mold shells. A first demolding mechanism is arranged between the first mold shells and enables movement of the first mold shells toward one another. A second demolding mechanism is arranged between the second mold shells and enables movement of the second mold shells toward one another.
