The split-flow injection molding mode of the framework is adopted, so that the section of a product can be conveniently and continuously debugged, the requirement is finally met, the mold does not need to be re-developed in the whole process, the development period of the mold is greatly shortened, and the development cost of the mold is also reduced.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
