The invention belongs to the technical field of
optical fiber coloring, and particularly relates to a coloring mold of a strip
optical fiber. The mold comprises a
frustum cone-like mold body, wherein a
fiber passing hole is formed in the mold body. The mold is characterized in that the outer surface of the side face of the mold body outwardly extends to form an ink feeding device; an ink inlet is formed in the center of the ink feeding device and is communicated with the
fiber passing hole; the joint of the ink inlet and the
fiber passing hole is positioned close to the lower side of the fiber passing hole; the ink inlet and the fiber passing hole are relatively inclined; a
frustum cone-like large section is formed on the upper part of the mold body; a sunken groove is formed in the upper part of the mold body; an arc stripe groove is formed from the lower side of the joint of the fiber passing hole and the ink inlet to the bottom of the mold body; the arc stripe groove is communicated with the fiber passing hole, and the outer arc
diameter of the arc stripe groove is more than the
diameter of the fiber passing hole. The invention further discloses a coloring method. The coloring mold mainly has the beneficial effects that the structure is simple, the manufacture is easy, ink can be saved while identification is not influenced after the coloring mold is used,
electricity is saved, the coloring speed is high, the service life of a curing light is long, and the coloring curing degree is high.
