A liquid crystal composition contains a side chain type polymer liquid crystalline compound which can form a light absorption anisotropic film having a high alignment degree and has excellent solubility in a general-purpose solvent, a light absorption anisotropic film obtained using the composition, a laminate, and an image display device. The composition includes: a side chain type polymer liquid crystalline compound; and a dichroic substance, in which the compound is a copolymer having a repeating unit (1) containing a mesogenic group with a molecular weight of greater than 280 and a repeating unit (2) with a molecular weight of 280 or less, a content of the repeating unit (2) is less than 14% by mass with respect to a total mass of the compound, and a content of the dichroic substance is greater than 2% by mass with respect to a total solid content of the composition.

The utility model discloses a device for removing bonded iron in a sand mold box of a brake drum molding pouring line, and relates to the related technical field of casting equipment processing. The device comprises a bottom supporting plate, a supporting box and pushing plates, the supporting box is fixed to the center of the top of the bottom supporting plate, a fixing block is fixed to the center of the top in the supporting box, first electric push rods are fixed to the four faces of the outer side of the fixing block, and the pushing plates are arranged on the four edges of the top of the bottom supporting plate. Second electric push rods are symmetrically fixed to the lower portions of the faces, away from the supporting box, of the push plates along the center line in the vertical direction, and a fixing plate is fixed to the ends, away from the push plates, of the second electric push rods fixed to the push plates. The bottom supporting plate, the supporting box and the pushing plate are arranged, so that the problems that a device for removing the bonded iron of the brake drum molding pouring line sand mold box is troublesome to limit the sand mold boxes with different sizes during working, and the adjacent surfaces are easily interfered when the bonded iron is removed are solved.
