Specific embodiment
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control attached drawing is described in detail
A specific embodiment of the invention.
As shown in Figs. 1-2, the present invention provides a kind of injection molded electronic injection unit, including ejecting mechanism, dosing machine
Structure and seat driving and reversing mechanism.
Ejecting mechanism is by injection linear guide, injection ballscrew nut fitting 8, the first toothed belt transmission 7, injection servo electricity
Machine 6 forms, wherein and it projects servo motor 6 and is connected with the small pulley of the first toothed belt transmission 7, the big band of the first toothed belt transmission 7
It takes turns and is connected with the nut for projecting ballscrew nut fitting 8, nut is rotated when projecting, and projects the screw rod of ballscrew nut fitting 8
It fixes to realize that projecting screw rod does straight reciprocating motion.
Metrological service is connected by metering servo motor 5, injection measure motor retarder 4, the second toothed belt transmission 3, screw rod
Axis 2, screw rod 1 and screw rod thrust pickup composition, wherein metering servo motor 5 is connect with measure motor retarder 4 is projected, and is penetrated
Measure motor retarder 4 is connected by the second toothed belt transmission 3 with screw rod connecting shaft 2 out, and screw rod connecting shaft 2 is connected with screw rod 1
To realize the linear motion of rotary motion and the injection of screw rod 1.
Seat driving and reversing mechanism goes up and down retarder 13, third toothed belt transmission by injection assembly elevating motor 12, injection assembly
14, assembly elevating screw pair of nut 11 is projected, assembly mounting plate 10 is projected, project assembly line slideway auxiliary 9 and projects assembly liter
Lower limit level sensor composition, wherein project assembly elevating motor 12 by projecting assembly lifting retarder 13 and be connected to third
One end of toothed belt transmission 14, the other end of third toothed belt transmission 14 and the screw rod phase for projecting assembly elevating screw pair of nut 11
Even, the nut for projecting assembly elevating screw pair of nut 11 is fixedly connected with assembly mounting plate 10 is projected to realize the liter for projecting assembly
Drop movement.
In the present embodiment, screw rod thrust pickup, injection assembly lifting limit sensors are all made of weighing type power sensing
Device is simultaneously installed between the support thrust bearing of screw rod connecting shaft 2, reversed in measure control for controlling injection servo motor 6
The size of power is projected in the speed and angle of rotation and monitoring when projecting.
The working time that servo motor 6 is projected when in the present embodiment, due to projecting is short, projects 6 driving force of servo motor
Square is big, and therefore, when servo motor 6 is projected in selection, the main maximum output torque for considering servomotor avoids servomotor
Power selection is excessive to cause that cost is excessively high and system bulk is excessive.
When the invention works, it projects assembly elevating motor 12 and first passes through the injection assembly lifting deceleration of retarder 13, then lead to
It crosses third toothed belt transmission 14 and drives the screw rod rotation for projecting assembly elevating screw pair of nut 11, screw rod rotation at this time drives nut
Linear motion, the injection assembly mounting plate 10 being connected with nut move along a straight line on projecting assembly line slideway auxiliary 9, make to penetrate
Mouth drops to the feed opening of mold.After nozzle reaches designated position, metering servo motor 5 works, and is subtracted by projecting measure motor
Fast device 4 slows down, then drives screw rod 1 to rotate by the second toothed belt transmission 3 and screw rod connecting shaft 2, the row rotated by screw rod 1
The feeding quantity in process control each period.In the process due to constantly there is melt to enter barrel front end, forces screw rod 1 to retreat, make
1 pressure rise of screw rod, provides the back pressure of charging, guarantees the metering accuracy of charging by screw rod thrust pickup monitoring back pressure, together
When this back pressure control project servo motor 6 reversely rotate, first pass through the first toothed belt transmission 7 drive project ballscrew nut fitting
8 nut rotation, the fixed screw rod of nut location moves along a straight line at this time, retreats screw rod 1 under suitable back pressure to setting
Position.After the completion of charging, metering servo motor 5 stops, and projects servo motor 6 and reversely rotates, and first passes through the first synchronous belt biography
Dynamic 7 drive the nut rotation for projecting ballscrew nut fitting 8, and nut rotates at this time and screw rod rotation is restrained, does screw rod directly
Line movement, so that the screw rod 1 for being connected in and projecting in linear guide be driven to move.Screw rod 1 is straight with certain speed to mold direction
Line movement promotes melting sizing material to enter die cavity within a certain period of time, and screw rod 1 stays for some time after reaching the limit of position, makes molten
Glue cooling and shaping in mold cavity completes an ejection formation movement.Hereafter, metering servo motor 5 acts, and starts next time
Project circulation.It when needing to lift nozzle, projects assembly elevating motor 12 and acts, make to project the position that assembly rises to setting.
The embodiment of the present invention is described with above attached drawing, but the invention is not limited to above-mentioned specific
Embodiment, the above mentioned embodiment is only schematical, rather than restrictive, those skilled in the art
Under the inspiration of the present invention, without breaking away from the scope protected by the purposes and claims of the present invention, it can also make very much
Form, all of these belong to the protection of the present invention.
