The brake disc sand box cooling and conveying device comprises a cooling channel, a conveying track and an exhaust fan, the exhaust fan comprises a fan body and a fan switch, a temperature measuring cylinder is arranged in the cooling channel, a piston is slidably connected in the temperature measuring cylinder, the space between the piston and the bottom wall of the temperature measuring cylinder is filled with mercury, the piston is fixedly connected with a linkage rod, and the linkage rod is fixedly connected with the conveying track. When the temperature of the sand box is reduced to the set temperature, the air temperature of the corresponding area is measured as the standard air temperature, the real-time air temperature of the corresponding area in the cooling channel is sensed through mercury in the temperature measuring cylinder, the real-time air temperature is compared with the standard air temperature, when the real-time air temperature is larger than the standard air temperature, the linkage block is separated from the fan switch, and the fan switch is switched off. The fan body operates; when the real-time air temperature is smaller than the standard air temperature, the linkage block abuts against the fan switch, and the fan body stops running. And after the temperature of the sand box is reduced to a set value, a subsequent fan in the conveying direction does not need to be started. The cooling device has the effect of reducing the energy loss of the brake disc blank casting in the cooling process.
