Specific embodiment
The present invention provides the cooling branching block of integrated form and its production technology.Below in conjunction with attached drawing to technical solution of the present invention into Row detailed description, so that it is more readily understood and grasps.
The cooling branching block of integrated form is set in hot runner system as shown in Figure 1 to Figure 3, the cooling branching block packet of integrated form The rectangular phosphor bodies of rule are included, rectangular phosphor bodies have six faces, and the first face 1, the second face 2 and third face 3 are mutually perpendicular to, and first Face 1 and fourth face 4 are opposite, and the second face 2 and the 5th face 5 are opposite, and third face 3 and the 6th face 6 are opposite.
Wherein, the inlet pipe 10 extended from the first face 1 to fourth face 4 and outlet tube road 20 are offered on the first face 1, into Liquid pipeline 10 is located at the through-hole on the first face 1 and to be located at the through-hole on the first face 1 be function matching hole 7, feed liquor on outlet tube road 20 Pipeline 10 and outlet tube road 20 are perpendicular with the first face 1 respectively.
If inlet pipe 10 is equipped with the liquid access 11 out that arterial highway extends towards the second face 2 and penetrates through the second face 2, liquid is logical out It is liquid matching hole 81 that road 11, which is located at the through-hole on the second face 2,.
If outlet tube road 20 is equipped with the feed liquor access 21 that arterial highway extends towards the second face 2 and penetrates through the second face 2, feed liquor is logical It is feed liquor matching hole 82 that road 21, which is located at the through-hole on the second face 2,.
And liquid matching hole 81 matches in pairs with feed liquor matching hole 82 out.Liquid access 11 and feed liquor access 21 are respectively with out Two faces 2 are perpendicular.
Inlet pipe 10 is equipped with the feed liquor input channel 12 for extending and penetrating through the 5th face 5 towards the 5th face 5, feed liquor input It is feed liquor input port 83 that access 12, which is located at the through-hole on the 5th face 5,.
Outlet tube road 20 is equipped with the liquid output channel 22 out for extending and penetrating through the 5th face 5 towards the 5th face 5, and liquid exports out It is liquid delivery outlet 84 that access 22, which is located at the through-hole on the 5th face 5,.
Feed liquor input channel 12 and liquid output channel 22 is perpendicular with the 5th face 5 respectively out.
Be additionally provided on rectangular phosphor bodies perforation the second face 2 and the 5th face 5 several mating ducts 8, and be coupled duct 8 with Free routing in rectangular phosphor bodies does not interfere with each other.So-called free routing refers to pipeline, access in rectangular phosphor bodies etc..
It specifically describes, by the cooling branching block of the integrated form as the cooling in cooling-cycle apparatus and hot runner system The bridge in channel.
Wherein, feed liquor input port 83 connects the liquid outlet of cooling-cycle apparatus, and liquid delivery outlet 84 connects cooling cycle out The circulation inlet of equipment, the feed liquor for going out each cooling duct that liquid matching hole 81 connects in hot runner system of inlet pipe 10 End, and the feed liquor matching hole 82 on the outlet end of each cooling duct connection outlet tube road 20.Realize water circulation.
Recycle flow path: the liquid outlet of cooling-cycle apparatus exports circulating cooling liquid, and circulating cooling liquid is along feed liquor input port 83 Into in inlet pipe 10, and by go out liquid access 11 through go out liquid matching hole 81 export, in cooling duct complete flow path after along into Liquid matching hole 82 enter feed liquor access 21 in, and behind outlet tube road 20 by go out liquid output channel 22 go out liquid delivery outlet 84 into Enter in cooling-cycle apparatus.So on circulate.
Using multiple groups matching pairs of liquid matching hole 81 and feed liquor matching hole 82 out, applicable multiple tracks cooling duct is cold simultaneously But operation.
And function matching hole 7 in practical where applicable, needs that function is coupled primarily to facilitate the molded design in duct Hole 7 is blocked, in addition, function matching hole 7 can load pressure test table, is surveyed to hydraulic in circulating cooling channel Examination.It is of course also possible to as spare feed liquor input port and it is spare go out liquid input port, can also with feed liquor input port and out liquid input Mouth doubleway output reflux.
Inlet pipe 10 is respectively perpendicular with liquid access 11 out, feed liquor input channel 12, and outlet tube road 20 and feed liquor access 21, go out liquid output channel 22 to be respectively perpendicular, be easy to pipe, access turnery processing, it is convenient for production.
In addition, spacing is greater than between 10 outlet tube road 20 of inlet pipe between feed liquor input port 83 and out liquid delivery outlet 84 Spacing.That is feed liquor input port 83 and liquid delivery outlet 84 is staggeredly located position out, because of feed liquor input port 83 and liquid delivery outlet 84 out Mating end is bigger than the mating end of liquid inlet and outlet matching hole, avoids the mating end interference of the two, in addition can provide more Space, the curved of adjustment can be turned to by, which being applicable in, connects end.
In specific embodiment, inlet pipe 10 is equipped with the liquid access 11 out of three phase uniform intervals setting, outlet tube road 20, which are equipped with three, corresponds matched feed liquor access 21 with liquid access 11 out, any matching it is pairs of go out liquid matching hole 81 with The line of feed liquor matching hole 82 is parallel with the first face.Shape is regular, easy to process.Its duct forms on similar dice six figure Shape.
Function matching hole 7, out liquid matching hole 81, feed liquor matching hole 82, feed liquor input port 83, liquid delivery outlet 84 has respectively out There is internal screw thread duct.
Function matching hole 7 goes out liquid matching hole 81, feed liquor matching hole 82, feed liquor input port 83, the opening for going out liquid delivery outlet 84 End is respectively equipped with sealing structure 9.The sealing structure 9 can improve mating leakproofness.
Specifically, sealing structure 9 includes single layer concave station sealing structure 91 or the double-deck concave station sealing structure 92.Single layer concave station is close One preferred structure of seal structure, interior concave ring stage are equipped with for assembling the ring of sealing ring recessed 911.Single layer concave station sealing structure Another preferred structure, interior concave ring stage be equipped with arc concave shape 912.
It is illustrated for arc concave shape 912, using cyclic sealing gasket, the inner ring diameter of cyclic sealing gasket is less than in arc Recessed 912 wide mouth part diameter, during the crimping of outside, cyclic sealing gasket can be embedded in arc concave shape 912, realize sealing.
The above sealing structure 9 is relatively suitably applied in the cooling branching block of integrated form of this case.
