Description
Technical field
The utility model relates to mold closing mechanism, relates in particular to a kind of hydraulic pressure gate mold closing mechanism, belongs to mechanical equipment technical field.
Background technology
If mold closing mechanism is divided into three kinds by the mode realizing mold clamping force: mechanical type mold closing mechanism, fluid pressure type mold closing mechanism, hydraulic mechanical type mold closing mechanism.Mechanical type mold closing mechanism: the power of motor by gear, toggle, link transmission, make ejector half seat board make opening and closing mould along pull bar to move, whole device adjustment is complicated, seldom adopts at present; The work characteristics of hydraulic pressure double-toggle mold closing device: boosting function: by crank connecting rod system, the thrust of closing liquid cylinder pressure can be amplified 16-26 doubly, compared with fluid pressure type mold closing mechanism, hydraulic oil consumption reduction, matched moulds cylinder diameter reduce, the corresponding reduction of power of pump.Conjunction, die sinking movement velocity are speed change, and in matched moulds process, ejector half seat board translational speed is raised to maximum very soon by zero, slows down gradually again later, and along with toggle bar stretches gradually to when stopping, closure pressing speed is zero, and mechanism enters self-locking state.The following problem of these device ubiquities: 1) complicated structure, cost is higher, and detachable maintaining comparatively bothers, 2), during work, structure is comparatively heavy, and energy consumption is large, poor rigidity; 3) in one action circulation, work fluid handling capacity is large, and easily cause work fluid to generate heat and go bad etc., therefore, a kind of new technical scheme of exigence solves above-mentioned technical problem.
Utility model content
The utility model is just for the technical problem existed in prior art, a kind of hydraulic pressure gate mold closing mechanism is provided, this equipment de-sign is ingenious, compact conformation, cost is lower, and this mold closing mechanism expands mold height scope, reduces the stroke of closing liquid cylinder pressure, improve operating efficiency, reduce energy consumption.
To achieve these goals, the technical solution of the utility model is as follows, hydraulic pressure gate mold closing mechanism, it is characterized in that, the rack piston hydraulic cylinder that described mold closing mechanism comprises closing liquid cylinder pressure, left flashboard, right flashboard and is arranged on above left flashboard and right flashboard, mobile hydraulic cylinder is provided with in described closing liquid cylinder pressure, be provided with between described mobile hydraulic cylinder and closing liquid cylinder pressure and eject hydraulic cylinder, described mold closing mechanism also comprises transmission component, and described transmission component is arranged on the top of closing liquid cylinder pressure.This technical scheme compact conformation, can realize quick matched moulds, improve operating efficiency.
Improve as one of the present utility model, the travelling gear that described transmission component comprises gear ring, is arranged on the gear on gear ring and is arranged between gear.
Improve as one of the present utility model, the closure pressing speed of described mold closing mechanism is 20-25m/min.
Improve as one of the present utility model, the diameter of described closing liquid cylinder pressure is 0.015-0.025m, and the length of closing liquid cylinder pressure is 0.25-0.5m.
Relative to prior art, the advantage of this technology is as follows: 1) the utility model overall construction design is ingenious, and compact conformation is practical; 2) this mold closing mechanism expands mold height scope, reduces the stroke of closing liquid cylinder pressure, improves operating efficiency, reduce energy consumption; 3) this technical scheme cost is lower, is convenient to apply on a large scale.

In figure: 1, left flashboard, 2, rack piston hydraulic cylinder, 3, right flashboard, 4, gear ring, 5, gear, 6, travelling gear, 8, shifting formwork hydraulic cylinder, 9, eject hydraulic cylinder, 10, closing liquid cylinder pressure.
Detailed description of the invention
In order to deepen understanding and cognition of the present utility model, below in conjunction with the drawings and specific embodiments the utility model be further described and introduce.
embodiment 1: see Fig. 1, Fig. 2, a kind of hydraulic pressure gate mold closing mechanism, the rack piston hydraulic cylinder 2 that described mold closing mechanism comprises closing liquid cylinder pressure 10, left flashboard 1, right flashboard 2 and is arranged on above left flashboard and right flashboard, mobile hydraulic cylinder 8 is provided with in described closing liquid cylinder pressure 10, be provided with between described mobile hydraulic cylinder 8 and closing liquid cylinder pressure 19 and eject hydraulic cylinder 9, described mold closing mechanism also comprises transmission component, and described transmission component is arranged on the top of closing liquid cylinder pressure 10.This technical scheme compact conformation, can realize quick matched moulds, improve operating efficiency.
embodiment 2: see Fig. 1, improve as one of the present utility model, the travelling gear 6 that described transmission component comprises gear ring 4, is arranged on the gear 5 on gear ring and is arranged between gear.All the other structures are identical with embodiment 1 with advantage.
embodiment 3: see Fig. 1, improve as one of the present utility model, the closure pressing speed of described mold closing mechanism is 20-25m/min; The diameter of described closing liquid cylinder pressure is 0.015-0.025m, and the length of closing liquid cylinder pressure is 0.25-0.5m.All the other structures are identical with embodiment 1 with advantage.
Operation principle: see Fig. 1, Fig. 2, , during matched moulds, first hydraulic oil enter the right chamber of shifting formwork hydraulic cylinder 8 from A hole, piston rod due to shifting formwork hydraulic cylinder is fixed on the rear support seat of fixed form, so cylinder body will together with moving platen rapid mould-moving, when the lock groove on cylinder body exposes, when walking to ram position, shifting formwork hydraulic cylinder fuel cut-off, now, the rack piston hydraulic cylinder 2 driving flashboard connected by hydraulic oil, piston is moved, by travelling gear 6, driving shaft, gear 5 drives left flashboard 1 to move right, simultaneously, the gear 5 of driving shaft left end is through gear ring transmission, driven wheel 12, power transmission shaft, gear 11, and then drive right flashboard to move to left, so, left and right flashboard simultaneously lock enters in the lock groove on shifting formwork hydraulic cylinder body, when flashboard walk to final position by shifting formwork hydraulic cylinder body locate after, hydraulic oil is passed into from the C mouth of closing liquid cylinder pressure, realize high pressure locking die, die sinking process is then contrary, first by the release of closing liquid cylinder pressure, then flashboard is opened, hydraulic oil is led to again to shifting formwork hydraulic cylinder B mouth, realize die sinking.This technical scheme is in order to expand the stroke of film tool altitude range and reduction closing liquid cylinder pressure, the cylinder body of shifting formwork hydraulic cylinder is provided with two banister grooves, the stroke of such closing liquid cylinder pressure only need equal two lock slot pitches from, and the adjustable range of film tool height is about the twice of matched moulds hydraulic cylinder travel.
At least one in technical characteristic described in embodiment 2,3 and embodiment 1 can also be combined to form new embodiment by the utility model.
It should be noted that above-described embodiment, be not used for limiting protection domain of the present utility model, equivalents done on the basis of technique scheme or the alternative scope all falling into the utility model claim and protect.
