Description
Technical field
The present invention relates to the reinforced ejecting mechanism of injection machine.
Background technology
Shown in Figure 1 is the charging and ejecting device of existing injection machine.Reinforced servomotor 3` dextrorotation (seeing from the motor tail end) is transferred to driven pulley two 2` through driving wheel two 4`, and drive screw 1` left-handed (seeing from motor shaft end) realizes the reinforced material action of stirring; With the reinforced action while; Penetrate servomotor 11` left-handed (seeing from the motor tail end), it is left-handed to drive driving wheel one 10`, and driving wheel one 10` drives driven pulley one 9` dextrorotation (seeing from motor shaft end); Driven pulley one 9` directly drives drive screw 5` dextrorotation; A 13` is fixing because transmission nut 6` is fixed can not move, so drive screw 5` is compelled to retreat in dextrorotation simultaneously, realizes loose deactuate work.Simultaneously, driven pulley one 9` is fixed on the drive screw 5` through spline 7` and gland 8`, so when drive screw 5` retreated, the drive mechanism that driven pulley one 9` and driven pulley one 9` are fixing, ejaculation servomotor 11` retreated simultaneously.
Penetrate servomotor 11` dextrorotation (seeing from the motor tail end), 5` is left-handed through driving wheel one 10`, driven pulley one 9` drive drive screw, and drive screw 5` rotating tee is crossed bearing 12` spinning movement is turned to translation, and lead-screw 1` advances, and accomplishes and penetrates action.While screw rod 1` drags driven pulley two 2` and driving wheel two 4`, the servomotor 3` that feeds in raw material advances; Drive screw 5` is being with driven pulley one 9`, driving wheel one 10` and is penetrating servomotor 11` and advance.More than penetrate the whole sampling action of action for whole charging.
Need a whole set of pulley transmission mechanism between reinforced servomotor and the screw rod, penetrating equally also needs a cover pulley transmission mechanism between servomotor and the drive screw, thrust bearing realization rotation also is set between screw rod and the drive screw flattens moving.The complicacy of its mechanism is obvious, brings cost to raise thus; Secondly owing to adopt the belt pulley transmission, the transmission accuracy is low; Have again; Motor and transmission mechanism all need be followed screw rod and moved, and in fact they all need be set on the mobile platform, and platform is very big together with the inertia of motor and transmission mechanism; When starting and brake, be difficult to accurately control its axial location, control accuracy is not high.
Summary of the invention
The mechanism of charging and ejecting device that the present invention will solve existing injection machine is complicated, moving-member is many, move the shortcomings that inertia is big, control accuracy is low, provide a kind of simple in structure, moving-member is few, the mobile charging and spraying device of injection molding machine that inertia is little, control accuracy is high, cost is low.
Charging and spraying device of injection molding machine of the present invention comprises:
One is arranged on the agitating screw that is used in the barrel to stir with pusher;
One is connected the drive screw at described screw rod rear portion;
It is characterized in that:
Described drive screw and described agitating screw are affixed;
Described drive screw is located on the reinforced servomotor; Described reinforced servomotor is the internal rotor servomotor; Described drive screw is connected on the pedestal of reinforced servomotor through bearing; Be with transmission nut on the described drive screw, described transmission nut connects the internal rotor of reinforced servomotor;
There is the extension at the rear portion of described drive bearing, and described extension is located in to be penetrated on the servomotor, and described extension is connected through bearing on the pedestal that penetrates servomotor, and key is connected between the rotor of described extension and described ejaculation servomotor.
Further, described ejaculation servomotor is an external rotor electric machine, and described extension connects the outer rotor of described ejaculation servomotor.
Further, described ejaculation servomotor is an inner rotor motor, and described extension connects the internal rotor of described ejaculation servomotor.
Further, the key type of attachment is between the rotor of described extension and described ejaculation servomotor: described extension is the angle rod, and the rotor of described ejaculation servomotor is connected with described angle rod.
The present invention realizes the reinforced entire exercise of penetrating with two hollow rotor servomotor interlocks.Penetrate servomotor to right rotation (seeing from motor shaft end), reinforced servomotor does not change, and serves as brake; Because of two motors are completely fixed, force to drive drive screw and retreat, drive agitating screw and retreat; Realize loose deactuate work, loose back speed degree is only relevant with the rotating speed that penetrates servomotor.Penetrate servomotor to right rotation (seeing) from motor shaft end; Reinforced servomotor is left-handed, and drive screw is retreated, and it is left-handed that reinforced servomotor drives the angle rod; The drive drive screw is left-handed; Drive screw drives that agitating screw is left-handed to be retreated, and realizes feeding in raw material, stirring the material action, and the astern speed of agitating screw is with being two hollow rotor servomotor rotating speed sums.Penetrate servomotor left-handed (seeing from motor shaft end), reinforced servomotor is motionless, serves as brake, and the compelled translation of drive screw is advanced, and drives the agitating screw translation and advances, and does and penetrates action.
The present invention adopts the two servomotors straight drive system that links, and simple and compact for structure, the operating efficiency of energy-efficient whole drive system can be up to more than 90%.Moving-member has only agitating screw and drive screw in the course of the work simultaneously, and motor is motionless fully, has reduced mobile inertia greatly, helps accurately controlling axial location.Have again; Combination through two motor steerings; On reinforced action and charging rate, very big adjusting space is arranged, can greatly curtail the feeding hours (in the 0.25S) realizes whole reinforced actions of penetrating such as ejaculation, rapid loading fast; Also can be adjusted to tens times even hundreds of times of short period time the whole charging time, satisfy to greatest limit each level customer demand.
Advantage of the present invention is: simple and compact for structure, cost is low, moving-member is few, move that inertia is little, control accuracy is high, and the adjustable range of reinforced action and charging rate is big.
