FIELD: production of castings for turbine engine members.
SUBSTANCE: proposed unit has mold core and mold for wax models. Mold core consists of ceramic rod and rod made from refractory metal. One end of rod made from refractory metal is inserted in slot found in ceramic rod and second end is brought in contact with wax mold for fixing its position relative to wax mold. Mold core made from refractory metal has at least one unit for forming the elastic load when wax mold is closed and/or wax mold locking mechanism for fixation of mold relative to core.
EFFECT: enhanced accuracy of position of mold core inside mold; possibility of obtaining good castings.
