The specific embodiment
As Fig. 1; 2a; shown in the 2b; four pressurized cylinders expand power formula double-template mould-clamping mechanism; closing cylinder seat 26; big thick stick 2; plate 11; the die cylinder 1 of two big relatively thick stick 2 left and right sides sides is housed on the closing cylinder seat 26; plate 11 connects cover half 10; die cylinder 1 drives with ejector half seat board 8 and is connected; ejector half seat board 8 connects dynamic model 9; Mode-locking oil cylinder piston 7 is housed on the Bottom clamp plate 8; the Mode-locking oil cylinder piston is divided into two cylinders with the locked mode cylinder; be respectively first group of pressurized cylinder 22 and second group of pressurized cylinder 23; nut installation seat plate 5 is housed above the Mode-locking oil cylinder piston 7; and clasp nut 3 is housed above the nut installation seat plate 5; open and close nut 20 with nut 3 left half-open and drive with folding cylinder body 14 and is connected, open with the right half-open nut 15 that closes of nut 3 and be connected with 13 drivings of folding oil cylinder piston, the folding oil cylinder piston is divided into two cylinders with the folding oil cylinder; be respectively the 3rd group of pressurized cylinder 24 and the 4th group of pressurized cylinder 25 and open with the internal thread of nut 3 external screw thread with big thick stick 2 and be complementary, ejector half seat board 8 is provided with magnetic railings ruler 12.
Adopt the die cylinder 1 that two big relatively thick stick 2 left and right sides sides are housed on the closing cylinder seat to drive ejector half seat board 8, on position, four Da Gang holes of moving platen, join the big pressurized cylinder of four areas.Before mould dynamic model 9 is not pressed close to cover half 10, adopt die cylinder 1 to drive ejector half seat board 8, the ejector half seat board is parked in dynamic model is about to close cover half and guarantees the position that clasp nut 3 dovetail grooves and big thick stick 2 dovetail grooves can accurately fasten, folding hydraulic oil cylinder driving clasp nut 3 accurately is buckled on the big thick stick 2.This moment, second group of pressurized cylinder charged into high-pressure and hydraulic oil, beginning supercharging locked mode.Mode-locking oil cylinder piston 7 and nut installation seat plate 5 are connected by bolted, clasp nut 3 only can slide on nut installation seat plate 5, clasp nut 3, nut installation seat plate 5, locking cylinder piston 7 axially all can not move relative to big thick stick 2, hydraulic oil can promote ejector half seat board 8 and press close to a typing plate 11, finishes the locked mode action.The pressurizing cylinder area is big, and the oil pressure height can provide bigger clamp force.
The locked mode action is finished, and can fill type, extruding, pressurize action, and pressurize finishes the back die sinking.During die sinking, second group of pressurized cylinder inner high voltage of emptying oil at first, guarantee that Mode-locking oil cylinder piston 7 is in lower limit, it is the state before ejector half seat board and Mode-locking oil cylinder piston relative position are got back to locked mode, die cylinder 1 driving ejector half seat board 8 is up then, arrive the appropriate location, die cylinder stops oil-filled, and die sinking finishes.
Big thick stick upper end has dovetail groove, with the dovetail groove of clasp nut be same specification, can accurately fasten for guaranteeing clasp nut 3 and big thick stick 2, the present invention adopts the stroke of 12 pairs of ejector half seat boards 8 of magnetic railings ruler to control.When die cylinder 1 driving ejector half seat board was descending or up, the action displacement was the integral multiple of big thick stick dovetail groove groove width.
Clasp nut is controlled folding by oil cylinder, and clasp nut is mainly formed one by three integral body: folding oil cylinder piston 13, the right half-open integral body 1 that nut 15, travel switch 17 and right limit cover 18 are formed of closing; Its two: folding cylinder block 14, a left side be half-open to close the integral body 2 that nut 20, connecting rod 16 and left limit cover 19 are formed; Its three: the framework spacing whole 3 that nut installation seat plate 5, folding pressing plate 4, right limit piece 6 and left limit piece 21 are formed.Whole 1 and whole 2 are subjected to the restriction of folding pressing plate 4, can only slide along the oil cylinder piston axis direction, and the left and right sides extreme position of slip is respectively left limit piece 21 and right limit piece 6 places.In the nut moving process, the 3rd cylinder in the folding cylinder block is oil-filled, folding oil cylinder piston 13 drives the right half-open nut 15 that closes and moves right, the cylinder block of folding simultaneously 14 promotes the half-open nut 20 that closes in a left side to left movement, after travel switch 17 is run into left limit cover 19, oil cylinder stops oil-filled, and the clasp nut opening procedure finishes; The 4th cylinder in the folding oil cylinder piston is oil-filled, and whole 1 to left movement, and whole 2 move right, travel switch 17 run into right limit cover 18 back oil cylinders stop oil-filled, clasp nut 3 closures.
When oil cylinder was oil-filled, integral body 1 and integral body 2 which part elder generation were moving, and perhaps moving does not simultaneously influence final nut opening and closing movement.Suppose when nut is opened, the 3rd cylinder in the folding cylinder block is oil-filled, whole 2 is motionless, whole 1 moves right earlier, close nut 15 and run into right limit piece 6 and can't continue again to move right when the right side is half-open, but this moment, stop collar was not run into the folding travel switch 17 that puts in place, oil cylinder continues oil-filled whole 1 stop motion, then whole 2 is inevitable to left movement under the effect of hydraulic oil, half-open the closing before nut 20 runs into left limit piece 21 on a left side, travel switch 17 is run into left limit cover 19 earlier, and oil cylinder stops oil-filled, and clasp nut 3 opening procedures finish.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
