The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Please also refer to Fig. 1 to Fig. 4, the mould 100 that embodiment of the present invention provides, it is for moulding fiber coupling connector (not shown), this optical-fiber coupling connector comprise for the blind hole of up-winding fiber and with the lens of this blind hole optical coupled.This mould 100 comprises that male model 10, master mold 20 and die enter son 30, and wherein this die enters son and 30 has afterbody 31 and blind hole forming part 32, and this blind hole forming part 32 is for the blind hole of this optical-fiber coupling connector of moulding.
This male model 10 carries out clamping position for this die being entered to the tail end of son 30.In the present embodiment, this male model 10 has a host cavity 11 and fixed block 12, and this host cavity 11 is for accommodating this fixed block 12.On this fixed block 12, offer accepting hole 13, this accepting hole 13 fixes for accommodating the afterbody 31 that this die enters son 30.
Understandable, this accepting hole 13 can be through hole or blind hole, certainly, this male model 10 can be also other fixed structure, if can after these mould 100 matched moulds, make this male model 10 can to this die enter son 30 afterbody 31 play accommodate fixing effect structure all applicable to the present invention.
This master mold 20 has a forming cavity 21, and this forming cavity 21 enters son 30 with this die and matches with this optical-fiber coupling connector of moulding.This forming cavity 21 has an optics portion forming surface 22, in this optics portion forming surface 22, is provided with lens forming part 221, and this lens forming part 221 is for the lens of this optical-fiber coupling connector of moulding.
