A kind of mould manufacturing double-pore structure fiber connector described above, it is characterised in that described pressing die, location mould, socket mould, the material of shaping mould are all steel or ferrum or alloy.
When the principle of the present invention is such that manufacturing double-pore structure fiber connector, shaping mould 4 is fixedly mounted on the base of press, and socket mould 3 is sleeved on shaping mould 4, and location mould 2 is arranged in socket mould 3, and pressing die 1 is sleeved on outside the mould 2 of location;First the first locating dowel 331 is inserted the first hole, location 421, second locating dowel 332 inserts the second hole, location 422,3rd locating dowel 332 inserts the 3rd hole, location, 4th locating dowel 334 inserts the 4th hole, location, belled body 32 inserts shrinkage pool 43, sleeve joint hole 321 is enclosed within outside the first pillar 44 and the second pillar 45, has reached shaping mould 4 and has fixed with the relative position of socket mould 3;Then injecting ceramic powder toward sleeve joint hole 321, arrive the appropriate location of below the first pillar 44 upper surface and keep a period of time, compacting ceramic material forms bottom and first fiber-optic fixing-hole 52 and second fiber-optic fixing-hole 53 of fiber connector body 5;Being put in sleeve joint hole 321 by location mould 2, the first pillar 44 is outer, the second location nib 212 is enclosed within outside the second pillar 45 to make the first location nib 211 be enclosed within again;Then in sleeve joint hole 321, ceramic powder is re-injected, arrive socket mould 3 upper surface position below, make pressing die 1 move downward, and make compacting hole 121 be enclosed within outside the mould body 21 of location, be pressed into suitable position and keep a period of time form the top of fiber connector body 5 and hold cable chamber 51;Complete the manufacture of the idiosome of fiber connector, then be sintered i.e. completing the manufacture of fiber connector.
After having suppressed, regain pressing die 1, take out location mould 2, regain socket mould 3, take out idiosome, i.e. complete the manufacture of fiber connector, also have bigger hardness due to idiosome, therefore can be taken out conveniently, will not deform;Then the residue in cleaning shaping mould 4.
For the first time during compacting, appropriate location, i.e. high and low position can determine that the height of the bottom of fiber connector body 5;The other flat board with shrinkage pool the 43, first pillar the 44, second pillar 45 phase is needed to suppress, plate diameter is slightly less than the diameter of shrinkage pool 43, the relevant position of flat board has the hole more slightly larger than the first pillar 44 diameter and the hole more slightly larger than the second pillar 45 diameter, and flat board can be enclosed within the first pillar 44 and the second pillar 45;During second time compacting, suitable position, the i.e. height on the top of fiber connector body 5, according to can demand determine.
Mould in the present invention can produce different length, various sizes of fiber connector.
In the present invention, first to fourth locating dowel is not limited to four, minimum can be two, of course, it is possible to be other many;Meanwhile, first to fourth hole, location is not limited to four, minimum can be two, of course, it is possible to be that other are multiple, as long as locating dowel can be accommodated.
In the present invention, the degree of depth of shrinkage pool 43 is 2.0mm ± 0.5mm.
In the present invention, a length of 8mm~25mm of socket mould body 31.
The present invention has a following main Advantageous Effects: simple in construction, easily make, and the double-pore structure fiber connector size of manufacture is unified, product qualified rate is high, manufacturing speed is fast, low cost;The joints of optical fibre volume that double-pore structure fiber connector is formed is little, lightweight.
The present invention is not limited to above-mentioned preferred forms, it will be appreciated that the design of the present invention can be implemented to use by other various forms, and they also fall within protection scope of the present invention.
