Specific embodiment
As shown in Figure 1 to Figure 3, the quick nozzle of injection machine of the present invention, including nozzle carrier 1 and the nozzle being connected with nozzle carrier 1
2。
Nozzle carrier 1 is overall cylindrical, and nozzle carrier 1 includes main part 108 and project to extend by the front end of main part 108 to be formed
Nozzle mounting seat 105, is provided with nozzle carrier 1 and arrange along the length direction of nozzle carrier 1 and pacify through main part 108 and nozzle simultaneously
The fluid passage of dress seat 105, the fluid passage of the inner side of nozzle carrier 1 is tapered into its aperture by rear end to front end, fluid passage bag
The less second fluid passage 106 of the larger first fluid passage 101 in aperture and aperture is included, and inclination is connected to first fluid and leads to
Between road 101 and second fluid passage 106 and in the 3rd fluid passage 102 of cone.First fluid passage 101, second
Body passage 106, the 3rd fluid passage 102 are coaxially disposed.The main part 108 of nozzle carrier 1 by leading exterior surface arrange for ease of with
The die nut position 104 that dismantling device coordinates, this die nut position 104 is easy to enter using spanner in the occasion for changing nozzle carrier 1
Row dismounting.The main part 108 of nozzle carrier 1 is provided with the connection screw thread being connected for the barrel head with injection machine by back end outer surface
103。
The rear end of nozzle 2 depression that faces forward is provided with docking recess 202, and the front end of docking recess 202 is provided with before nozzle 2
The nozzle passage at end, the docking recess 202 of nozzle 2 is directly sleeved on the outer surface of nozzle mounting seat 105, table in docking recess 202
Face and the outer surface of nozzle mounting seat 105 are not provided with screw thread, and the cell wall of 2 docking recess of nozzle 202 is gap with nozzle mounting seat 105
Coordinate.The nozzle passage of the inner side of nozzle 2 is tapered into its aperture by rear end to front end, and nozzle passage includes larger first in aperture
The less second nozzle passage 204 of nozzle passage 203 and aperture, and incline be connected to first jet passage 203 and second nozzle
Between passage 204 and in the 3rd nozzle passage 207 of cone, first fluid passage 101, second fluid passage the 106, the 3rd flow
Body passage 102, first jet passage 203, second nozzle passage 204, the 3rd nozzle passage 207 are coaxially disposed, and first jet leads to
The aperture in road 203 is equal with the aperture of second fluid passage 106, before the rear end of first jet passage 203 and second fluid passage 106
End is smooth without dead angle docking.The front end face of nozzle 2 is set to sphere 206, and the front end ejiction opening 205 of second nozzle passage 204 runs through
Sphere 206, so arrange preferably to coordinate with cast gate.
During work, nozzle carrier 1 is arranged on into the barrel head of injection machine by connection screw thread 103（Not shown in figure）On, will
Nozzle 2 is directly sleeved on nozzle carrier 1 away from the outer surface of 103 one end nozzle mounting seat of connection screw thread 105, between nozzle 2 and nozzle carrier 1
Without the need for threaded connection, injection machine（Not shown in figure）Material is carried out plus hot-extrudable, heated material is squeezed from barrel head
Go out into the fluid passage of nozzle carrier 1, material is successively through first fluid passage 101, the 3rd fluid passage 102, second
Body passage 106, subsequently flows into the nozzle passage of nozzle 2, and passes through first jet passage 203, second nozzle passage respectively
204th, the 3rd nozzle passage 207, fluid injects mould from the ejiction opening 205 of nozzle 2.Fluid enters the fluid passage of nozzle carrier 1
With, because passage bore is gradually reduced, the flow velocity that can make fluid is improved, so as to faster from ejection after the nozzle passage of nozzle 2
Mouth 205 is molded into mould, small-bore each corner that can be more accurately ejected into mould cavity at ejiction opening 205,
Avoid causing vacancy, injection effect is more preferable.
Nozzle 2 is directly sleeved in the nozzle mounting seat 105 of nozzle carrier 1, is not threadedly coupled between the two, is belonged to gap and is matched somebody with somebody
Conjunction relation.The end face of the discharging opening 107 of nozzle carrier 1 is adjacent to the nozzle 2 being enclosed within nozzle mounting seat 105.During production and application, nozzle
2 cast gates that must push against mould, can just carry out normal production cycle.During normal production cycle, nozzle 2 is necessary
All the time the cast gate of mould is pushed against, must not be left.
When occur nozzle 2 be blocked in the case of, can by operate injection machine so that nozzle 2 leaves mould gate about
10mm or so, beats action of injection, and nozzle 2 is separated with the end face of the discharging opening 107 of nozzle carrier 1.Then make injection machine and penetrate move back after platform
Make, nozzle big end surface 201 can be rapped with waddy or copper rod, nozzle 2 is removed.The nozzle mounting seat of clear clean nozzle carrier 1
The plastics remained with the end face of discharging opening 107 on 105, can load onto at standby nozzle at once, make injection machine and penetrate precession before platform
Make, nozzle 2 is pushed against into the cast gate of mould, then restart the normal production cycle of injection machine.Just now the nozzle 2 removed, can
Individually to be cleared up in injection machine normal productive process, after cleaning out, acknowledgment copy is given over to, to occurring nozzle next time
What is blocked uses again.The disassembly process of whole nozzle 2, convenient, fast, the time for changing nozzle 2 greatly shortens, and improves work
Effect, also shortens the stand-by time of injection machine, so as to more environmentally friendly and energy-conservation simultaneously.
The practicality of combining structure of the present invention is good, breaches the side that the nozzle 2 in conventional thought must be threaded connection
Formula is fastened, and initiative employs the mode of movable connection, is provided using upper Synergistic and energy-saving for present injection machine special dimension
New thinking, is particularly well-suited to require that operating efficiency is higher, occasion that produced using recycled plastic.
Above example is only presently preferred embodiments of the present invention, and the structure of the present invention is not limited to what above-described embodiment was enumerated
Form, all any modification, equivalents made within the spirit and principles in the present invention etc., should be included in the guarantor of the present invention
Within the scope of shield.
