    [0102] Optionally, referring to FIG. 3, furthermore, the mold core 20 further comprises a horizontal segment 207 disposed between the first conical segment 201 and the second segment 202 conically.
    [0104] Optionally, referring to Figures 3 and 4, a fixation fin 208 is provided on an outer surface of horizontal segment 207. Therefore, assembly stably with the mold sleeve 10 using the fixing tab 208 is possible, and meanwhile, an auxiliary effect can be created to prevent eccentric assembly.
    [0105] Optionally, referring to Figure 3, there is also provided an assembly slot 209 that can be assembled with the plastic extruder on the outer surface of horizontal segment 207. Therefore, the mold core 20 is stably assembled.

Therefore, a sheath wire is fixed extending into each hole. In this case, a cross section of the support fixture tube 210 can be established as the hole diameter varies.
    [0109] It is to be particularly noted that in the embodiment described above, FRP refers to glass fiber reinforced plastic. This is a composite material made using fiberglass and its product (glass fabric, belt, felt, thread or the like) as a reinforcing material and using a synthetic resin as the base material. Its mechanical resistance is equivalent to that of steel, since it also contains a glass component, and it also has the color, shape and properties such as corrosion resistance, electrical insulation and thermal insulation like glass, therefore, it is also called enameled steel.
    [0111] The aforementioned perforation may be formed by tight fit of a perforated tubular structure composed of a FRP material to the mold sleeve 10, or the mold sleeve 10 itself may be composed of an FRP material or the like, for example, its own. The mold is made of high quality die steel. A mold made of high quality die steel by high temperature tempering has extremely excellent performance and can meet the basic performance of optical cable. The five-hole mold can meet the usage requirements for optical cables, and can provide ideas for further development of more molds.
