Abstract
The electric compound type clamping mechanism comprises an actuating motor, a screw assembly and a crown pillar. The actuating motor is connected with a leading screw of the screw assembly, and a leading screw nut of the screw assembly is fixed on the crown pillar connected with a moving template. The mechanism comprises a mould locking device which is controlled by an oil pressure. The mould locking device is in a high pressure mode locking oil cylinder in an inner rear template. High pressure oil penetrates into a mode locking cavity, promotes a mode locking piston which can transmit mode locking force to the mould through split nuts, crown pillar surfaces with outside threads and the moving template. The mechanism has the advantages of fast and stable running, high positioning accuracy, and good repeatability. A mould thickness adjusting device is arranged to conveniently and reliably adjust the mould.
Description
Technical field
The present invention relates to the clamping of injection machine.
Background technology
Three plate direct press type hydraulic mold-locking mechanism switching moldings in the past adopt small oil tank to drive, line slideway guiding.Locked mode adopts hydraulic pressure vertical compression mould clamping, and short stroke Mode-locking oil cylinder is built in template.Clamp force is passed to moving die plate by mechanical locate mode band brake apparatus, can realize limit die sinking limit obvolvent and open.Three plate direct press type hydraulic mold-locking mechanisms are used same set of power unit, by accumulator, cannot not carry out composite move, increase the injection machine injection cycle time.
Summary of the invention
Technical problem to be solved by this invention is to overcome the above-mentioned deficiency of prior art and a kind of electric combined-type mold clamping mechanism is provided, and can effectively solve the problem that can not carry out composite move that three plate direct press type hydraulic mold-locking mechanisms exist.
The present invention solves the problems of the technologies described above adopted technical scheme:
Electric combined-type mold clamping mechanism; comprise servomotor, lead screw pair and a fore-set; servomotor is connected with the leading screw in lead screw pair; feed screw nut in lead screw pair is fixed on the fore-set being connected with moving platen; also comprise the mold locking device that oil pressure is controlled, be included in the high-voltage lock mould oil cylinder of rear pattern plate inside, hydraulic oil enters Mode-Locking Cavity and promotes locking piston; locking piston, via splitting cohesion nut, is with externally threaded fore-set surface and moving platen that clamp force is passed on mould.
During folding mould, servomotor does not directly drive ball-screw and by feed screw nut, drives fore-set, moving platen and mould moving linearly by this via speed reduction gearing.Instantaneous high pressure breaks mould by the high axially rated load leading screw of high pulling torque driven by servomotor, and pulls the fore-set and the moving platen that are attached thereto to realize by leading screw.
In above-mentioned electric combined-type mold clamping mechanism, be also provided with mold thickness adjustment device; comprise one section of fore-set surface, the cohesion nut of controlled molding jig thickness adjusting position, obvolvent oil cylinder with collar nut; obvolvent oil cylinder is fixed on oil cylinder seat; obvolvent piston rod and cohesion nut are fixed; obvolvent oil cylinder seat is arranged on locking piston, and cohesion nut is controlled and clamped and leave fore-set by obvolvent oil cylinder.Because shifting formwork stroke is certain, cohesion nut clamped position regulates and has determined to hold mold thickness.
Compared with prior art, the invention has the advantages that:
Electric combined-type clamping mechanism performance servomotor position control accuracy is high; speed is controlled good; cancel motor and execution unit speed reduction gearing, improved transmission efficiency, strengthened transmission rigidity; reduce transmission noise; General Promotion switching molding speed and precision, machine operation is faster, more steady; positioning precision is higher, and repeatability is better.
By this mold thickness adjustment device is set, its mould is regulated more convenient, reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is the profile of embodiment of the present invention mold thickness regulating device;
Fig. 3 is embodiment of the present invention cohesion nut stroke controlling structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described.
Servomotor 1 is connected with leading screw 2, and leading screw 2 is fixed on support 11, and support is fixed on rear pattern plate 12, and leading screw 2 coordinates with the screw 3 that is fixed on fore-set 5 one end, and fore-set 5 other ends and moving platen 4 are fixing.
After servomotor 1 starts, by key connecting, drive leading screw 2 to rotatablely move, leading screw 2 gives screw 3 axial feed power.Because screw 3 is fixed on fore-set 5, fore-set 5 just promotes moving die plate 4 and makes axially reciprocating.
Moving die plate 4 is placed on line slideway 28, and line slideway 28 is used as moving die plate motion guide.
Also comprise the mold locking device that oil pressure is controlled; be included in the high-voltage lock mould oil cylinder 14 of rear pattern plate 12 inside; hydraulic oil enters Mode-Locking Cavity 13 and promotes locking piston 6, and locking piston 6 is via splitting cohesion nut 7, being with externally threaded fore-set surface 8 and moving platen 4 that clamp force is passed on mould.
Mold thickness adjustment device is also set; comprise one section of fore-set surface 8, the cohesion nut 7 of controlled molding jig thickness adjusting position, obvolvent oil cylinder 15 with collar nut; obvolvent oil cylinder 15 is fixed on oil cylinder seat 21; obvolvent piston rod 27 is fixing with cohesion nut 7; obvolvent oil cylinder seat 21 is arranged on locking piston 6, and cohesion nut is controlled and clamped and leave fore-set 5 by obvolvent oil cylinder 15.Due to can optional position band-type brake on the fore-set of collar nut at this section of fore-set surface.Because shifting formwork stroke is certain, cohesion nut clamped position regulates and has determined to hold mold thickness.
Between above-mentioned cohesion nut 7 and locking piston 6, wear-resistant gasket 20 is also set, mill pad 20 surfaces are higher than locking piston 6 surfaces, and locking piston 6 is close to mill pad 20, in cohesion nut obvolvent and in opening stroke, plays wear-resisting effect.
On the obvolvent guide plate 22 of above-mentioned cohesion nut 7, bearing 23 is installed, bearing 23 one side is pressed cohesion nut 7, like this in cohesion nut obvolvent and open in stroke, is arranged on bearing 23 on obvolvent guide plate 22 and provides guiding for cohesion nut.Bearing simultaneously presses cohesion nut, and this makes obvolvent piston rod and cohesion nut synchronization action, thereby does not produce side force protection obvolvent piston rod 27.
As shown in Figure 3, cohesion nut stroke is controlled by a pair of inductive pick-up that closely connects being arranged on the two proximity switch supports 16 of obvolvent.When cohesion nut is held tightly, the inductive pick-up 29 that closely connects that level is arranged on the two proximity switch supports of obvolvent senses the signal that approaches sensor block side 17 from obvolvent, and obvolvent stops.When cohesion nut is opened, the inductive pick-up 19 that closely connects being vertically mounted on the two proximity switch supports of obvolvent senses the signal that approaches sensor block end face 18 from obvolvent, opens termination.
As shown in Figure 1; in above-mentioned clamping, moving platen 4 adopts and flexibly connects with line slideway 28; moving platen 4 is placed in moving platen and supports on rebound 24; moving platen supports rebound 24 with moving platen and is connected by guide 25; guide installation site is positioned at moving platen and supports rebound center, and soket head cap screw connects moving platen from below through guide.Moving platen supports rebound with moving platen and only at this, is connected, and straight-line guide rail slide block is installed on moving platen and supports on rebound.
