Cooling structure of busbar mold

The invention provides a cooling structure of a busbar mold. The cooling structure of the busbar mold comprises a mold body. A plurality of forming grooves are linearly formed in the mold body. Cooling devices are arranged below the forming grooves. The cooling structure of the busbar mold is characterized in that the mold body comprises a constant-temperature area, cast welding areas and heat preservation areas. The forming grooves are formed in the cast welding areas. One independent cooling device is correspondingly arranged in each cast welding area. Each cooling device comprises a cooling body which is arranged below the corresponding cast welding area and/or the corresponding heat preservation area, wherein a liquid inlet pipe is arranged on the cooling body in the arrangement direction of the corresponding forming groove, and a water injection nozzle is arranged on the liquid inlet pipe and faces the bottom of the corresponding forming groove; and a backflow groove is further formed in the cooling body
