DETAILED DESCRIPTION

[0017] The technical solutions 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, rather than 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.

[0018] Please refer to Figures 1-9The utility model provides the following technical scheme: the utility model discloses a fiber plastic grating strip extrusion mould, including injection nozzle 1, mould frame 2, first mould core 3 and second mould core 4, the end face of first mould core 3 with second mould core 4 mutually fits in with and is linked together, the injection channel is set up in mould frame 2, the injection channel includes feed port 5 with discharge port 6, the mould frame 2 sets up assembly groove 7, the assembly groove 7 with discharge port 6 are linked together, the first mould core 3 is set up and goes into line port 8, the second mould core 4 sets up and goes into line port 9, the first mould core 3 with second mould core 4 can detachably connect in assembly groove 7, the first mould core 3 with second mould core 4 are provided with the feed groove 10 that goes into line with discharge port 6, the first mould core 3 is provided with the coating cavity 11 in.

[0019] In the above structure, the first mould core 3 and the second mould core 4 are detachably connected in the assembly groove 7, which facilitates the separate disassembly, maintenance or replacement of the first mould core 3 and the second mould core 4 when the mould is worn or fails, reduces the maintenance cost, and improves the service life of the mould; through the injection nozzle 1, the injection channel, the feed groove 10 and the coating cavity 11, the raw materials are uniformly coated on the wire, and the fiber plastic grating strip can be stably produced; the assembly groove 7 and the discharge port 6 are connected through the assembly groove 7 of the mould frame 2, the wire inlet 8 and the coating cavity 11 on the first mould core 3, and the line inlet 9 on the second mould core 4, so that the raw materials can flow along the preset path, enter the coating cavity 11 smoothly from the injection nozzle 1.
