Bridge elbow pipe fitting core

The utility model relates to the technical field of bridge elbow pipe fitting injection molds, in particular to a bridge elbow pipe fitting mold core which comprises a left mold core and a right mold core, a first cooling water channel is arranged in the left mold core, a second cooling water channel is arranged in the right mold core, and the first cooling water channel and the second cooling water channel are in mirror symmetry. The first cooling water channel comprises a first spiral structure and a second spiral structure wound with the first spiral structure, and the first spiral structure and the second spiral structure extend from the end, away from the right mold core, of the left mold core to the other end of the left mold core. According to the utility model, the defect of low production efficiency caused by poor cooling effect of the inner mold core in the prior art is overcome, and the cooling water channels of the left mold core and the right mold core are both of the double-helix structure, so t
