The invention discloses an intelligent spraying device for a shield segment mold. The intelligent spraying device comprises a moving system, a wiping system, a drying system, a sprinkle coating system, a spraying system, a roll coating system and a feeding system, wherein the wiping system, the drying system, the sprinkle coating system, the spraying system, the roll coating system and the feedingsystem are located on one side of the moving system in sequence. According to the intelligent spraying device for the shield segment mold, water removal and real-time quality inspection are carried out on a mold release agent through the feeding system before the material mixing operation, it is ensured that the supplied mold release agent raw material has low water content, denaturation due to long-term mixing with water of the release agent does not occur, and the mold release agent raw material and water are fully stirred under the constant temperature condition, so that the prepared moldrelease agent is good in quality and guarantees the follow-up coating operation; multi-time coating operation is carried out on the inner wall of the mold by means of multiple coating modes, the positions such as faces, points, wee positions, bent positions and irregular positions can be uniformly coated with the mold release agent, and the influence of the surface condition of the mold on the film forming quality of the mold release agent is weakened to the maximum extent, so that the demolding process of the mold in the follow-up operation process can be smoothly completed.
