Abstract
The invention discloses a ball screw pair-driven clamping mechanism. The ball screw pair-driven clamping mechanism comprises four pull rods, a tail plate, two toggle mechanisms, a movable mould plate, a head plate, a synchronous pulley, a screw bearing base, a ball screw, a ball nut and a thrust block, wherein the four pull rods fix the distance between the head plate and the tail plate and are used for guiding movement of the movable mould plate. The ball screw pair-driven clamping mechanism is driven by a servo motor; and through a toothed synchronous belt and a ball screw pair, rotation of the motor is converted into back-and-front movement of the thrust block to drive a toggle link mechanism so as to open and close the movable mould plate.

Technical field
The present invention relates to a kind of Clamping Device of Injection Moulding Machine, relate in particular to a kind of clamping of ball-screw auxiliary driving.
Background technology
In the matched moulds parts of traditional injection machine, promote thrust bearing by hydraulic jack and seesaw, by elbow-bar mechanism power is amplified again, obtain the opening and closing movement of moving platen and enough large clamp forces.Yet there are many defectives in traditional fluid power system, one, and its characteristic is difficult to keep after operation and oil temperature change continuously, and control accuracy is affected; Its two, hydraulic system since inertia cause greatly easy to wear, noise is large; Its three, run duration maintenance difficult, energy consumption are high.So change into by driven by servomotor, use ball-screw-transmission, design new clamping transmission device.
Summary of the invention
The object of the invention is to the defectives such as low, easy to wear for existing hydraulic-driven Clamping System control accuracy, that maintenance is difficult, noise is large, energy consumption is high, a kind of clamping of ball-screw auxiliary driving is provided.The present invention adopts servomotor to drive, and by tooth form synchronous belt and ball screw assembly,, converts rotatablely moving of motor to thrust bearing move forward and backward, and drives crank connecting rod mechanism, realizes the opening and closing movement of moving platen.
The objective of the invention is to be achieved through the following technical solutions: a kind of clamping of ball-screw auxiliary driving, it comprises: four pull bars, tailgate, two elbow-bar mechanism, moving platen, a plate, synchronous pulley, lead screw shaft bearing, ball-screw, ball nut and thrust bearings etc.; Wherein, have corresponding four tie rod holes on described plate, moving platen and tailgate; Four pull bar one ends all are fixed on the plate, after the other end passes the tie rod hole of moving platen, are fixed on the tailgate, and the distance of four pull bar gland plates and tailgate, and be used for the motion guide of moving platen; Synchronous pulley is installed in ball-screw one end by key and nut; Ball-screw is supported by the lead screw shaft bearing, and the lead screw shaft bearing is fixed on the central through hole of tailgate; The ball nut screw thread is screwed in the other end of ball-screw, thrust bearing is fixed on the ball nut, thrust bearing has up and down two supports, two cover toggle linkages form by small rod, back link and front rod up and down, one end of small rod links to each other with a support of thrust bearing by bearing pin, and the other end is connected on the back link by bearing pin, and an end of back link is connected with tailgate by bearing pin, the other end links to each other with front rod by bearing pin, and the other end of front rod connects moving platen by bearing pin; Plate is fixed on it the injection machine, and tailgate places on the fuselage 9 by the copper packing pin of bottom, the left and right sides.
Further, all overlapping in four tie rod holes of described moving platen has guide copper sleeve, and pull bar all passes guide copper sleeve.
The invention has the beneficial effects as follows, the clamping of ball-screw auxiliary driving of the present invention is stressed even, symmetrical, avoids unbalance loading.Ball thick stick auxiliary driving rigidity is high, accurate positioning; Driven by servomotor, energy-conservation; Owing to using servomotor, toggle link is stopped in different angles, therefore be conducive to the change of clamp force and can carry out compression forming; Because do not have the impact of oil shock inertia, so noise is low, control accuracy is higher; Tailgate bottom slip, the impact in the time of slowing down the folding mould increases the service life.

The specific embodiment
Further specify the present invention below in conjunction with accompanying drawing, it is more obvious that purpose of the present invention and effect will become.
As depicted in figs. 1 and 2, the clamping of ball-screw auxiliary driving of the present invention comprises: four pull bars 1, tailgate 2, two elbow-bar mechanism, moving platen 7, a plate 10, synchronous pulley 13, lead screw shaft bearing 14, ball-screw 15, ball nut 16, thrust bearing 17.
Have corresponding four tie rod holes on plate 10, moving platen 7 and the tailgate 2.As shown in Figure 3.Four pull bar 1 one ends all are fixed on the plate 10, after the other end passes the tie rod hole of moving platen 7, are fixed on the tailgate 2.The distance of four pull bars, 1 gland plate 10 and tailgate 2, and be used for the motion guide of moving platen 7.Synchronous pulley 13 is installed in ball-screw 15 1 ends by key 12 and nut 11.Ball-screw 15 is supported by lead screw shaft bearing 14, and lead screw shaft bearing 14 is fixed on the central through hole of tailgate 2.Ball nut 16 screw threads are screwed in the other end of ball-screw 15.Thrust bearing 17 is fixed on the ball nut 16, and thrust bearing 17 has up and down two supports.Two cover toggle linkages form by small rod 4, back link 5 and front rod 6 up and down, one end of small rod 4 links to each other by the support of bearing pin with thrust bearing 17, the other end is connected on the back link 5 by bearing pin, one end of back link 5 is connected with tailgate 2 by bearing pin, the other end links to each other with front rod 6 by bearing pin, and the other end of front rod 6 connects moving platen 7 by bearing pin.
Four tie rod holes of moving platen 7 are enclosed within on the pull bar by guide copper sleeve 8, as shown in Figure 5, and toward guide copper sleeve 8 interior injection lubricating oil, the frictional resistance when reducing moving platen 7 motion.
