The invention provides a PC component die table cleaning device. The PC component die table cleaning device comprises a main frame, a scraper plate is hinged to one side of the main frame, a scraper air cylinder is arranged between the scraper plate and the main frame, a distance measuring sensor is arranged in the part, on the side of the scraper air cylinder, of the main frame, and the device further comprises a lifting mechanism, a sweeping structure, a dust removal mechanism and a die table transportation mechanism. According to the PC component die table cleaning device, the defects of anexisting die table cleaning device can be effectively overcome, for the lifting mechanism of a brush roller, a lead screw is driven by adopting a servo motor, so that the ascending and descending movement of the brush roller is realized, and the sweeping action force can be controlled; the structure is simple, the control is easy to realize, and a cloth bag dust remover for dust is arranged, so that the pollution to the environment caused by sweeping is reduced; and therefore, the device has the advantages of being simple in structure, easy to control, high in sweeping efficiency and the like.
