Zusammenfassung:The utility model relates to a glue injection opening structure of a glue injection mold, which comprises a mold, a glue injection opening is arranged on the mold, the bottom of the glue injection opening is communicated to an inner cavity of the mold, the glue injection opening structure further comprises a plugging opening, the plugging opening is communicated with the bottom end of the glue injection opening, and a plugging column is connected in the plugging opening in a sliding mode. And the bottom surface of the plugging column can slide and plug the glue injection port. One purpose of the utility model is as follows: in the glue injection process, the plugging column is opened to carry out glue injection operation, and the plugging column is pushed to plug the glue injection port after glue injection is completed, so that the mold cavity becomes a sealed cavity, and the plugging column can ensure the smoothness of the inner surface of the mold cavity and the smoothness of the surface of a product witho
