Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of injection molding apparatus and injection molding forming method of the joints of optical fibre.
Background technology
Along with optical fiber in the application of the communications field more and more widely, the electric signal transmission yarn system of equipment such as many information products of popularization and application at present, communication audiovisual changes the main media that transmits as signal for the high efficiency joints of optical fibre gradually by early stage plain conductor.The device of the described joints of optical fibre for can between optical fiber and optical fiber, removably connecting, by the accurate butt joint of two end faces of optical fiber is got up, can make the light energy of launching fiber output be coupled to greatest extent to receive in the optical fiber and go, make signal via joints of optical fibre inside ccontaining fiber core line transmit.
A kind of joints of optical fibre of integral type, it adopts the method manufacturing of injection mo(u)lding.Fig. 6 A to Fig. 6 D is this joints of optical fibre t1, t2, t3, t4 four moment of priority in process of injection molding, the sunykatuib analysis figure of molten plastic flows in the shaping mold cavity.This joints of optical fibre comprise the fore-end that forms collector lens, reach the rear end part that forms up-winding fiber and point to the accepting hole of described collector lens.By Fig. 6 A to Fig. 6 D as can be known, after molten plastic injected the die cavity that forms the joints of optical fibre from running gate system, under the effect of injection pressure, being that middle mind-set die cavity is mobile all around with cast gate filled.
But in this case, molten plastic can not be filled from the front to the zone that forms collector lens preferably.Thus, the forming surface that makes collector lens is vulnerable to the unbalanced impact of molten plastic, is unfavorable for the complete moulding of collector lens, and finally influence the optical effect of collector lens.In addition, molten plastic will be to two side flow after arriving the fore-end that forms collector lens, thus, molten plastic forms horizontal direct impact to the son of going into of moulding optical fiber accepting hole in the die cavity, easily make and particularly go into sub-front end into son and more carefully locate to produce distortion even cause into the son fracture, to influence the final molding of the joints of optical fibre thus, and and then influence the production yield of goods.
Summary of the invention
In view of this, be necessary to provide a kind of easy realization, can effectively improve the injection molding apparatus and the injection molding forming method of the joints of optical fibre of the problem that existing fiber connector injection molding process exists.。
A kind of injection molding apparatus of the joints of optical fibre comprises a mould.Described mould has a die cavity and a running gate system, described die cavity comprises ante-chamber and the back cavity that communicates, the cast gate of described running gate system leads to described back cavity, described ante-chamber has the zone that forms light-collecting lens, be useful on the son of going into that forms the optical fiber accepting hole in the described back cavity, describedly go into the both sides that son is positioned at the position of the corresponding described cast gate of described back cavity, and describedly go into son and point to the zone that forms light-collecting lens in the described ante-chamber.Described injection molding apparatus further comprises a block, and described block cooperates the injection molding apparatus that forms the described joints of optical fibre with described mould, and described block inserts the back cavity of described mould, and is located at the side of described cast gate near the ante-chamber of described mould.
A kind of injection molding forming method of the joints of optical fibre, its step comprises: the injection molding apparatus that a kind of aforesaid joints of optical fibre are provided; Injection molding apparatus injection moulding to the described joints of optical fibre.The block of described injection molding apparatus stops that the molten plastic of the back cavity that injects described mould directly flows to the ante-chamber of described mould, make molten plastic walk around described block and flow to described ante-chamber from the both sides of described block, be full of described die cavity until molten plastic, form the described joints of optical fibre.
Compared to existing technical scheme, the injection molding apparatus of the joints of optical fibre of the present invention is cooperated with block by mould and forms, the feasible injection molding forming method of the joints of optical fibre of described injection molding apparatus that adopts has following advantage: one, inject the molten plastic of die cavity owing to be subjected to the barrier effect of block, the zone of walking around block and form collector lens from two side direction die cavitys of block flowed fill, thus, the forming surface that can improve collector lens is subjected to the situation of the unbalanced impact of molten plastic, and then makes collector lens have optical effect preferably.Its two, molten plastic is being walked around block and from two side direction die cavity front end process of flowing of block, is along the axial flow of going into son substantially, thus, can avoid being subjected to the horizontal direct impact of molten plastic, guarantee sub-moulding optical fiber accepting hole, obtain the joints of optical fibre preferably into son.
