Title:
FIVE-HOLE RIBBON FIBER OPTIC CABLE MOLDING DIE
Document Type and Number:
WIPO Patent Application WO/2019/109806
Kind Code:
A1
Abstract:
A five-hole ribbon fiber optic cable molding die comprises a die cover (10) and a die core (20) matching the die cover (10). The die core (20) has a central through hole (203), and a round FRP through hole (204) and an oval-shaped FRP through hole (205) taking two diameter lines of the central hole (203) perpendicular to each other as lines of symmetry. The outer circumference of the die core (20) has a first taper section (201) and a second taper section (202). The first taper section (201) is in contact with the die cover (10). The conicity of the second taper section (202) is less than the conicity of the first taper section (201). The conicity of the die core (20) determines two conical angles for the two sections thereof, such that a melt material forms a homogeneous material flow after extrusion by a compression section of a screw, and the molded surface of a fiber optic cable becomes smoother after further extrusion by the first taper section (201) and the second taper section (202).
