Description
Technical field
The utility model relates to the clamping of injection machine.
Background technology
Three plate direct press type hydraulic lock mold mechanism switch moulds in the past adopt small oil tank to drive, the line slideway guiding.Locked mode adopts the hydraulic pressure vertical compression mould clamping, and the short stroke Mode-locking oil cylinder is built in the template.Clamp force is passed to moving die plate by mechanical locate mode band brake apparatus, can realize that limit die sinking limit obvolvent opens.Three plate direct press type hydraulic lock mold mechanisms use same set of power unit, can't not carry out composite move by accumulator, increase the injection machine injection cycle time.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency of prior art and a kind of electronic combined type clamping is provided, and can solve the problem that can not carry out composite move that three plate direct press type hydraulic lock mold mechanisms exist effectively.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
Electronic combined type clamping; comprise servomotor, lead screw pair and a fore-set; servomotor is connected with leading screw in the lead screw pair; on the fore-set that feed screw nut in the lead screw pair is fixed on moving platen is connected; 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 the locked mode chamber and promotes locking piston; locking piston is with externally threaded fore-set surface and moving platen that clamp force is passed on the mould via splitting cohesion nut.
Servomotor does not directly drive ball-screw and drives fore-set, moving platen and mould moving linearly by feed screw nut by this via speed reduction gearing during the folding mould.Instantaneous high pressure breaks mould then by the high axially rated load leading screw of high pulling torque driven by servomotor, and is realized by fore-set and moving platen that the leading screw pulling is attached thereto.
Also be provided with mold thickness adjustment device in the above-mentioned electronic combined type clamping; the one section fore-set surface, the cohesion nut of controlled molding jig thickness adjusting position, the obvolvent oil cylinder that comprise band shape nut; the obvolvent oil cylinder is fixed on the oil cylinder seat; obvolvent piston rod and cohesion nut are fixed; the obvolvent oil cylinder seat is installed on the locking piston, and cohesion nut clamps and leave fore-set by the control of obvolvent oil cylinder.Because the shifting formwork stroke is certain, the cohesion nut clamped position is regulated and has been determined to hold mold thickness.
Compared with prior art, advantage of the present utility model is:
Electronic composite clamping mechanism performance servomotor position control accuracy height; speed-controllable is good; cancellation motor and execution unit speed reduction gearing have improved transmission efficiency, have strengthened transmission rigidity; reduce the transmission noise; promote switch mould speed and precision, the machine operation is faster, more steady comprehensively; positioning accuracy is higher, and repeatability is better.
By this mold thickness adjustment device is set, it is more convenient, reliable that its mould is regulated.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the profile of the utility model embodiment mold thickness regulating device;
Fig. 3 is the utility model embodiment cohesion nut stroke controlling structure schematic diagram.
The specific embodiment
Embodiment is further described the utility model below in conjunction with accompanying drawing.
Servomotor 1 is connected with leading screw 2, and leading screw 2 is fixed on the support 11, and support is fixed on the rear pattern plate 12, and leading screw 2 cooperates with the screw 3 that is fixed on fore-set 5 one ends, and fore-set 5 other ends and moving platen 4 are fixing.
Servomotor 1 starts the back and rotatablely moves by key connecting drive leading screw 2, and leading screw 2 gives screw 3 axial feed power.Because screw 3 is fixed on the fore-set 5, fore-set 5 just promotes moving die plate 4 and makes axially reciprocating.
Moving die plate 4 places on the line slideway 28, and line slideway 28 is made the usefulness of moving die plate motion guide.
The mold locking device that also comprises oil pressure control; be included in the high-voltage lock mould oil cylinder 14 of rear pattern plate 12 inside; hydraulic oil enters locked mode chamber 13 and promotes locking pistons 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 the mould.
Mold thickness adjustment device also is set; the one section fore-set surface 8, the cohesion nut 7 of controlled molding jig thickness adjusting position, the obvolvent oil cylinder 15 that comprise band shape nut; obvolvent oil cylinder 15 is fixed on the oil cylinder seat 21; obvolvent piston rod 27 is fixing with cohesion nut 7; obvolvent oil cylinder seat 21 is installed on the locking piston 6, and cohesion nut clamps and leave fore-set 5 by 15 controls of obvolvent oil cylinder.But owing to optional position band-type brake on the fore-set of fore-set surface this section band shape nut.Because the shifting formwork stroke is certain, the cohesion nut clamped position is regulated and has been determined to hold mold thickness.
Between above-mentioned cohesion nut 7 and the locking piston 6 wear-resistant gasket 20 is set also, wear-resistant gasket 20 surfaces are higher than locking piston 6 surfaces, and locking piston 6 is close to wear-resistant gasket 20, in the cohesion nut obvolvent and open and play wear-resisting effect in the stroke.
Bearing 23 is installed on the obvolvent guide plate 22 of above-mentioned cohesion nut 7, and bearing 23 one sides are pressed cohesion nut 7, and like this in the cohesion nut obvolvent and open in the stroke, the bearing 23 that is installed on the obvolvent guide plate 22 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, the cohesion nut stroke is controlled by a pair of inductive pick-up that closely connects that is installed on the two proximity switch supports 16 of obvolvent.When cohesion nut was held tightly, the inductive pick-up 29 that closely connects that level is installed on the two proximity switch supports of obvolvent was sensed from the signal of obvolvent near sensor block side 17, and then obvolvent stops.When cohesion nut was opened, the inductive pick-up 19 that closely connects that is vertically mounted on the two proximity switch supports of obvolvent was sensed from the signal of obvolvent near sensor block end face 18, then opens termination.
As shown in Figure 1; moving platen 4 adopts with line slideway 28 and flexibly connects in the above-mentioned clamping; moving platen 4 places moving platen to support on the rebound 24; moving platen supports rebound 24 with moving platen and is connected by guide 25; the guide installation site is positioned at moving platen and supports the rebound center, and soket head cap screw passes guide and connects moving platen from the below.Moving platen supports rebound with moving platen and only is connected at this, and the line slideway slide block is installed on moving platen and supports on the rebound.
