A gum injection nozzle structure used for injecting seal gum is used for solving the problem that the forming state of the seal gum is unreasonable. According to the technical scheme, the gum injection nozzle structure comprises a gum injection nozzle and a locking cap; a locking cap hole is arranged in the locking cap, a gum fluid passage is arranged in the gum injection nozzle, the locking cap hole is communicated with the gum fluid passage, and a material outlet communicated with the gum fluid passage is arranged at the lower part of the gum injection nozzle; after the improvement, a chamfer is arranged on one side of the lower part of the gum injection nozzle, a side inclined opening is formed at the chamfer; the material outlet is composed of a bottom opening and the side inclined opening which are communicated. The gum injection nozzle structure changes the stressed condition of gum at a gum outlet, enables the seal gum to be raised in a gum strip after gum injection of a sealing strip product, increase
