Specific embodiment:
With reference to the accompanying drawing and specific embodiment the present invention will be described in detail:
A kind of injection mechanism of injection machine of quick response as shown in Figure 1, including injection tube 1, screw rod 2, penetrate platform 3, fixed station 4,
Upper plate 5, telescoping cylinder 6, vacuum air pump 7 and control module, the fixed station 4 is fixedly mounted on the body of injection molding machine, described
2 lower end of screw rod is extend into inside injection barrel 1, and 2 upper end of screw rod is connected with platform 3 is penetrated, and the upper plate 5 passes through bearing fixing sleeve
It connects on 2 body of rod of screw rod penetrated between platform 3 and injection tube 1, in feeding, due to being connected between upper plate 5 and screw rod 2 by bearing
It connects, therefore when screw rod 2 rotates, upper plate 5 will not be rotated with screw rod 2, and 6 cylinder body of telescoping cylinder is fixedly mounted on fixed station 4
Top, the piston rod of the telescoping cylinder 6 are fixedly mounted on 5 lower part of upper plate, described to stretch in order to guarantee 2 two sides stress balance of screw rod
Contracting cylinder 6 is at least symmetrical arranged a pair in the two sides in 2 axle center of screw rod, and 6 inferior part of the cylinder block of telescoping cylinder passes through pipeline 8 and vacuum suction
Machine 7 is connected, it is described penetrate platform 3, vacuum air pump 7 is connected with control module, first control module control vacuum air pump 7
The cylinder body of telescoping cylinder 6 is evacuated, when telescoping cylinder 6 is in vacuum state, under the action of atmospheric pressure, telescoping cylinder 6
Piston rod has downward active force to upper plate 5, and control module control at this time is penetrated platform 3 and acted, and is penetrating platform 3, extraneous is forcing greatly
Under power and the collective effect of vacuum air pump 7, achieve the purpose that fast injection.
During practical application, in order to realize the protection to bearing, the Bearing outer is provided with bearing holder (housing, cover) 9, with
It avoids influencing production efficiency because of bearing damage.
Meanwhile in order to increase telescoping cylinder 6 in the case where being in vacuum state to the active force of screw rod 2, to realize fast injection
Purpose, it is preferred that there are four the quantity settings of the telescoping cylinder 6.
In addition, being provided with pressure inductor 10 on the pipeline 8, the pressure inductor 10 is connected with control module,
Because the cylinder body of pipeline 8 and telescoping cylinder 6 is in communicating state, therefore the pressure inside pipeline 8 and the pressure phase inside telescoping cylinder 6
Logical, so, the pressure of induction is passed to control module by pressure inductor 10, then controls vacuum air pump by control module
Control is adjusted in pressure inside 7 pairs of telescoping cylinders 6.
The stroke distances of 6 piston rod of telescoping cylinder are 2 times~3 times of 2 stroke distances of screw rod, using this structure, both
In order to meet the stroke demand of screw rod 2, while telescoping cylinder 6 can also be increased and be in active force under vacuum state to screw rod 2.
It is emphasized that: the above is only presently preferred embodiments of the present invention, not make in any form to the present invention
Limitation, any simple modification, equivalent change and modification to the above embodiments according to the technical essence of the invention,
All of which are still within the scope of the technical scheme of the invention.
