Abstract
The invention relates to a die used for moulding a fiber coupling connector. The die comprises: die core inserts used for moulding a blind hole; a master die, consisting of a moulding cavity equipped with a lens moulding part and locating pieces disposed in the moulding cavity, with each of the locating pieces provided with a locating slot for clamping and locating the die core inserts so as to make the die core inserts in alignment with the lens moulding part; a spur, which is positioned the master die and communicated with the moulding cavity so as to inject a moulding material into the moulding cavity, with the opening direction of the locating slot towards the spur. By defining the opening direction of the locating slots towards the spur, the die provides a support force in the direction of the spur to the die core inserts so as to counteract impact forces of a moulding material on the die core inserts, thus ensuring the coupling precision of a moulded product.
