Description

Technical Field

[0001] The utility model relates to a coating mould, belonging to the technical field of moulds. Background Art

[0002] The coating mold includes an outer mold, a middle mold and an inner mold. The outer surfaces of the middle mold and the inner mold are processed with flow channels to achieve a double-layer diversion coating structure. The adjustment ring connected to one end of the outer mold is set on the core mold, and then one end of the core mold extends to the mouth mold base mold. In order to facilitate the adjustment of the relative position of the mouth mold base mold and the core mold, a plurality of screw holes are usually processed on the surface of the adjustment ring, and then the adjustment screws are threadedly connected in the plurality of screw holes.
