The device for unpacking and de-sanding of cast mold part (7) casting in mold sand and mold box (6), comprises a compressed air reservoir (2), an air-and sand-permeable underlayer (3) and a collection container (4). The compressed air reservoir has an opening corresponding to the cross sectional area of the mold box and is directly arranged by sealing means over the sand surface. The air-and sand-permeable underlayer is arranged at a distance under the mold box in collection container. The air- and sand-permeable underlayer is formed as a carrier means such as a grill or a pallet. The device for unpacking and de-sanding of cast mold part (7) casting in mold sand and mold box (6), comprises a compressed air reservoir (2), an air-and sand-permeable underlayer (3) and a collection container (4). The compressed air reservoir has an opening corresponding to the cross sectional area of the mold box and is directly arranged by sealing means over the sand surface. The air-and sand-permeable underlayer is arranged at a distance under the mold box in collection container. The distance between the upper edge of the collection container and the upper edge of the air-and sand-permeable underlayer is less than the half height of a half of the mold box. The air- and sand-permeable underlayer is formed as a carrier means such as a grill or a pallet or conveyor belt for the mold parts. An independent claim is included for a method for unpacking and de-sanding of cast mold part.
