FIELD: metallurgy.
SUBSTANCE: tooling for the core manufacturing contains the casting mould (40) for feeding the ceramic mass in which the working cavities (42, 44) of one the first part and at least one other part of the core are performed and facilities (50, 54) for supporting and sealing the end parts of the ceramic rod, that connects the mentioned core parts and passes through the working cavity of the first core part. In the working cavity of the first core part the tooling contains the facilities (58) of the rod middle part support.
EFFECT: prevention of the rods breakage, when feeding the ceramic mass into the mould.
