A kind of die opening mechanism with mechanical gain, including base, the quiet mold mounting plate being arranged on base, the dynamic model installing plate being engaged with quiet mold mounting plate, for driving dynamic model installing plate movable to realize the transmission mechanism of open/close mould action；The transmission mechanism includes screw, the nut being set in outside screw, connecting rod, the handwheel loaded on screw end, and connecting rod is movably hinged between dynamic model installing plate and nut.Compared with prior art, instant invention overcomes the manual opening and closing Mo Shiyi shifts occurred and model damage phenomenon, the present invention is simple in construction, and manufacturing cost is low, and use range is wide；Using screw-driven, mechanism kinematic is accurate, reliable, and mold clamping force is big, will not cause the swollen type of mould and runout；It is easy to operate, it is only necessary to which that opening and closing mold process can be achieved in hand handwheel, reduces labor intensity.The present invention extends die life.The operating time of opening and closing mould is short, improves the production efficiency of product.
Description
Technical field
The present invention relates to a kind of die opening mechanism with mechanical gain.
Background technology
In numerous auto parts and components manufacturing enterprises, there is many casting Manual molds, for Single unit job lot production or
The Foundry Production of the less product of volume weight.The opening and closing mold process of traditional Manual mold pulls on and off by hand by founder
The completion of sound mould is closed, labor intensity, production efficiency is low, and folding mold process is unstable；It is clamping fixed using mould after mould assembly, exist
It is unreliable to clamp, easy swollen type and runout in casting process, and the permanent use of mould folder is easily deformed and damaged, it is necessary to often change
The problem of.Process portion can not realize accurate, reliable control such as processes such as cast, matched moulds, die sinkings as machining, only
It can be held by the experience of operator, therefore easily cause that qualified casting is low, the phenomenon of unstable product quality.
The content of the invention
It is an object of the invention to overcome the above-mentioned deficiency of prior art, and a kind of simple in construction, action is provided and precisely may be used
Lean on, the larger die opening mechanism with mechanical gain of mold clamping force.
Technical program of the present invention lies in：Including base, be arranged at quiet mold mounting plate on base, with quiet mold mounting plate phase
The dynamic model installing plate of cooperation, for driving dynamic model installing plate movable to realize the transmission mechanism of open/close mould action；The biography
Motivation structure includes screw, the nut being set in outside screw, connecting rod, the handwheel loaded on screw end, and connecting rod is movably hinged in dynamic model
Between installing plate and nut.
The screw is differential screw, including left hand thread portion, right-handed thread portion；The nut is two, nut A suits
In left hand thread portion, nut B is set in right-handed thread portion；It is respectively two that the connecting rod, which is divided into connecting rod A, connecting rod B, A and connecting rod B,
Root, two connecting rod A one end are movably hinged with nut A, and two connecting rod B and nut B is movably hinged, and the two connecting rod A other ends, two connecting rod B are another
One end is movably hinged with dynamic model installing plate respectively.
The nut A, nut B are symmetrically loaded on screw.
The two connecting rods A is symmetrically placed in nut A both sides, and two connecting rod B are symmetrically placed in nut B both sides.
Equipped be hinged journal stirrup on the dynamic model installing plate, two connecting rod A, two connecting rod B are movably hinged on be hinged journal stirrup.
The base includes bottom plate, the biside plate positioned at bottom plate sidepiece, and screw both ends warp beam is taken up on biside plate.
Mounting hole is provided with the biside plate, bearing is loaded at mounting hole.
The bottom plate is provided with the chute for being used for coordinating dynamic model installing plate to move.
The present invention is simple in construction, and manufacturing cost is low, and use range is wide；Using screw-driven, mechanism kinematic is accurate, reliable,
Mold clamping force is big, will not cause the swollen type of mould and runout；It is easy to operate, it is only necessary to which that opening and closing mold process, drop can be achieved in hand handwheel
Low labor intensity.Due to the drive characteristic of screw-nut, the mould has auto-lock function, prevents the swollen type of mould.With prior art
Compare, instant invention overcomes the manual opening and closing Mo Shiyi shifts occurred and model damage phenomenon, extend die life.Open,
The operating time of matched moulds is short, improves the production efficiency of product.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is Fig. 1 top view.
Embodiment
In Fig. 1,2, the present invention includes base 1；It is arranged on base 1：Transmission mechanism, the dynamic model being connected with transmission mechanism
Installing plate 3, the quiet mold mounting plate 2 being engaged with dynamic model installing plate 3.Transmission mechanism is connected differential including handwheel 4, with handwheel 4
Screw 5, the nut A6 and nut B8 coordinated with differential screw, and two connecting rods 7 and two connecting rod B9.Differential screw 5 is installed
In on base 1.Dynamic model installing plate 3 and connecting rod A7 and connecting rod B9 passes through axis connection；Nut A and nut B and connecting rod A7 and connecting rod B9
Connected by rotating shaft.Quiet mold mounting plate 2 is fixed loaded on bottom plate 1.Nut A and with the mating part screw thread of differential screw 5 to be left-handed,
Nut B and be dextrorotation with the mating part screw thread of differential screw 5.
The stationary mould for mould of needs before use, be connected, dynamic model and dynamic model installing plate 3 by the present invention with quiet mold mounting plate 2 first
Connection, ensure that the action of mould opening and closing mould is accurate after installing.
In use, as shown in Fig. 2 transhipment handle 4, differential screw 5 drive nut A6 and nut B8 to away from counterclockwise
Heart line direction is moved, and the connecting rod being connected with nut drives the die sinking of dynamic model installing plate.Operative employee is cleared up mould, spray paint etc.
After operation, handle 4 is transported clockwise, differential screw 5 drives nut A6 and nut B8 to be moved to away from centerline direction, with nut
The connecting rod of connection drives dynamic model installing plate matched moulds.During matched moulds, because the drive characteristic and connecting rod of screw-nut are leaned on to centre
Hold together, produce very big mechanical gain, be finally brought into close contact mould, while screw-nut has auto-lock function, prevents that mould is swollen
Type.Matched moulds is poured into a mould afterwards in place, after reaching open time, is transported handle 4 clockwise and is molded, take out casting.The production of product
During repeat more than act.
