PURPOSE: A precise shaping apparatus of a ferrule for optical fiber is provided to shape the precise ferrule by minimizing distortion of a core pin formed in the inside of a mold for shaping the ferrule in an injection work. CONSTITUTION: A fixing portion(10) is installed at one side of an injection portion. A plurality of guide bars(11) is mounted on an upper portion and a lower portion of the fixing portion(10). A moving portion(20) is combined with the guide bars(11). The moving portion(20) is fixed to a piston rod of a cylinder(12) installed in an upper side and a lower side of the fixing portion(10). A raw material injection hole(21) is formed in a center of the moving portion(20). A plurality of injection paths is formed at an outer side of the raw material injection hole(21). A plurality of guide holes(22) is formed at an outer side of the raw material injection hole(21). A molding member(30) is located a position facing the moving portion(20). A plurality of shaping holes(31) is formed in the molding member(30). The shaping holes(31) are used for shaping a ferrule. A plurality of guide bars(32) is formed at one side of the molding member(30). The guide bars(32) are combined with a support portion(40). A plurality of operating bars(41) is installed in the support portion(40). The support portion(40) is operated by a driving portion(50). The driving portion(50) is formed with a shaft bolt(51), a ball nut(53) combined with the shaft bolt(51), and a servo motor(54).
