[0019] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] Please refer to Figures 1-4This embodiment provides a technical solution: an injection mold, including a lower mold 2, an integrally formed molding groove 6 on the inner side of the lower mold 2, an injection tube 7 on the bottom surface of the molding groove 6, a connecting threaded groove 11 at the lower end of the injection tube 7, an injection insertion tube 9 inserted into the lower mold 2, a threaded hole 10 on the upper side of the injection insertion tube 9 corresponding to the position of the injection tube 7, an injection mold box 4 at one end of the injection insertion tube 9, clamping and fixing edges 8 on the four sides of the injection mold box 4, an insertion tube 12 at the end of the injection insertion tube 9 near the injection mold box 4, and a sealing ring 13 on the outer ring side of the insertion tube 12.

[0021] like Figures 1-4 As shown, the upper mold 1 slides downward along the guide post 3, causing the upper mold 1 and the lower mold 2 to close. Then, the hot melt plastic to be injection molded is squeezed into the injection mold box 4 through the injection tube 5, and injected into the molding groove 6 through the injection tube 7 on the upper side of the injection tube 9, so that the hot melt plastic can be molded in the molding groove 6. When it is necessary to clean the pipe inside the lower mold 2, the injection tube 7 is removed from the injection tube 9, then the clamping bolt on the clamping and fixing edge 8 is removed, the injection mold box 4 is removed, and the injection tube 9 is pulled out from the inside of the lower mold 2.
