FIELD: manufacturing technology.
SUBSTANCE: invention relates to metallurgy, particularly, to production of wax model of turbomachine blade by injecting wax into mold cavity. Mold cavity is formed by at least two elements, which are fixed in blocks (6, 11). Both pulleys are movable relative to each other in horizontal plane between closed position for injecting wax and open position for extraction of model. Drive units is made in form of fixed base plate (4) and movable plate (9), moving progressively relative to base plate.
EFFECT: enabled is simplified design of casting mould and high quality of wax model due to elimination of deformations and failures model at its extraction.
