FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, in particular to casting with directional crystallisation. Monocrystalline smelting mould (1) comprises moulding cavity (7), starter cavity (10), having at least first volume (10a) in form of inverted funnel and second volume (10b), forming a plinth in the lower part of the first volume. Second volume protrudes horizontally relative to the first volume. Selector channel (9) connects said starter cavity (10) to the lower part of shaping cavity (7). In order to support the model, there is support rod (20), offset laterally relative to the selector channel, and connecting second volume (10b) of the starter cavity (10) with the shaping cavity (7). Moulding process is carried out using mold (1).
EFFECT: required mechanical strength of the mould is provided when pouring molten metal.
