Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 3, an integrated ferrule mold for producing an optical cable includes a mold sleeve 40 and a mold core 20 inserted into the mold sleeve 40 and coaxially engaged with the mold sleeve 40, a circumferential ferrule material passage 50 is formed between the mold sleeve 40 and the mold core 20, a fiber passage 70 passing through from left to right is opened at the center of the mold core 20, and a plurality of fiber paste passages 60 passing through from left to right are uniformly opened on the mold core 20 around the fiber passage 70. In this embodiment, the number of the paste passages 60 is eight.
Specifically, a plurality of positioning holes are uniformly formed in the left end face of the die sleeve 40 along the circumferential direction, positioning pins 30 which are equal in number and matched with the positioning holes in a one-to-one correspondence manner are screwed on the end face, opposite to the left end face of the die sleeve 40, of the die core 20, and coaxial positioning is achieved between the die sleeve 40 and the die core 20 through the positioning pins 30. In this embodiment, the number of the positioning holes is six. The utility model discloses in, mold core 20 adopts rapid Assembly integral type structure with die sleeve 40, realizes endocentric function through locating pin 30, has guaranteed that the sheathed tube wall thickness is even. The stepped surface of the locating pin 30 determines the size of the sleeve material passageway 50 between the mold core 20 and the mold sleeve 40.
In addition, above-mentioned integral type sleeve pipe mould for optical cable production is still including fixing the oil filling seat 10 on the left end face of mold core 20 (oil filling seat 10 passes through the fix with screw on the left end face of mold core 20), the centre bore that link up and with fibre channel 70 looks adaptation about the oil filling seat 10 center is seted up, the equal and one-to-one fibre cream groove with fine cream passageway 60 quantity is seted up around the centre bore on the oil filling seat 10 right-hand member face, each fine cream groove left end is through a hoop groove intercommunication, the fine cream import groove of intercommunication hoop groove is seted up to oil filling seat 10 bottom.
