FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy, particularly to making the parts with cavities, for example, coolant or lubricant ducts. Said cavities are made with the help of soluble cores. To accommodate and support the core in mould proposed is the device composed of support tube 3 with narrow cylindrical part 5. The latter is to be fitted in the core 1 to be supported. Said tube can be fitted in another tube, or in chill mould, or in the other tube. After casting hardening, said tube allow the access to core for dissolution and washing it off by solvent.
EFFECT: reliable retention of small cross-section cores.
