FIELD: production of castings in vacuum film molds. SUBSTANCE: flasks are connected to one another into conveyer by intermediate plates and provision of box conveyer with movable drive bottom plates. After casting into molds as soon as skin strong enough is formed on casting surface, castings are transferred to boxes. This takes place in synchronous motion of conveyer. Box bottom plate found under flask gradually lowers to free space in box for sand lump with casting moved under gravity. After cooling, castings are removed by separate conveyer. EFFECT: reduced number of flasks, saved production areas and improved convenience in operation. 2 cl, 10 dwg
