FIELD: foundry, namely production of casting molds and cores solidified in fitting with use of gaseous solidifying agent. SUBSTANCE: apparatus for making casting molds and cores includes apertural plate with gas insulation passages for feeding sand to fitting connected with gas-feed and gas- exhaust shaping members; gas collecting cavity with gas-exhaust pipeline. Apparatus includes in addition gas-feed shaping member having gas insulation ducts for feeding sand to fitting. Said ducts are arranged in parallel with openings of gas injection plate. Gas-feed and gas- exhaust members are made of cermet material having gas permeability of gas-feed member equal to 80-1000 units and gas-exhaust member equal to 30-500 units. EFFECT: improved design. 3 dwg
