Description
Technical field
The utility model relates to a kind of die opening mechanism with mechanical gain.
Background technology
In numerous auto parts and components manufacturing enterprise, have and much cast Manual mold, for the Foundry Production of Single unit job lot production or the less product of volume weight.The opening and closing mold process of traditional Manual mold is pulled open by founder and closes sound mould by hand and completes, labour intensity, and production efficiency is low, and folding mold process is not steady; Adopt mould holder to fix after mould assembly, there is clamping unreliable, easy swollen type and runout in casting process, mould holder uses easily distortion for a long time and damages, and needs the problem often changed.Process portion cannot realize controlling accurately, reliably as processes such as cast, matched moulds, die sinkings as machining, can only rely on the experience of operator to hold, therefore easily cause qualified casting low, the phenomenon of unstable product quality.
Summary of the invention
Goal of the invention of the present utility model is the above-mentioned deficiency overcoming prior art, and provides the die opening mechanism of the band mechanical gain that a kind of structure is simple, action is accurate reliably, mold clamping force is larger.
The technical solution of the utility model is: comprise base, is arranged at the quiet mold mounting plate on base, the dynamic model installing plate matched with quiet mold mounting plate, the transmission mechanism that realizes the action of open/close mould for driving dynamic model installing plate to move forward and backward; Described transmission mechanism comprises screw, the nut be set in outside screw, connecting rod, be loaded on the handwheel of screw end, and connecting rod is movably hinged between dynamic model installing plate and nut.
Described screw is differential screw, comprises left hand thread portion, right-handed thread portion; Described nut is two, and nut A is set in left hand thread portion, and nut B is set in right-handed thread portion; Described connecting rod is divided into connecting rod A, connecting rod B, A and connecting rod B to be respectively two, and two connecting rod A one end and nut A are movably hinged, and two connecting rod B and nut B are movably hinged, and the two connecting rod A other ends, the two connecting rod B other ends are movably hinged with dynamic model installing plate respectively.
Described nut A, nut B symmetry are loaded on screw.
Described two connecting rod A are symmetrically placed in nut A both sides, and two connecting rod B are symmetrically placed in nut B both sides.
Described dynamic model installing plate is equipped with hinged journal stirrup, and two connecting rod A, two connecting rod B are movably hinged on hinged journal stirrup.
Described base comprises base plate, is positioned at the biside plate of base plate sidepiece, and screw two ends warp beam takes up on biside plate.
Described biside plate all has installing hole, and bearing is loaded on installing hole place.
Described base plate is provided with the chute for coordinating the movement of dynamic model installing plate.
The utility model structure is simple, low cost of manufacture, and the scope of application is wide; Adopt screw-driven, accurately, reliably, mold clamping force is large, can not cause the swollen type of mould and runout for mechanism kinematic; Easy to operate, only need hand handwheel can realize opening and closing mold process, reduce labour intensity.Due to the drive characteristic of screw-nut, this mould has auto-lock function, prevents the swollen type of mould.Compared with prior art, the utility model overcomes shift and the model damage phenomenon of manual opening and closing Mo Shiyi appearance, extends die life.The operating time of opening and closing mould is short, improves the production efficiency of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
In Fig. 1,2, the utility model comprises base 1; Be arranged on base 1: transmission mechanism, the dynamic model installing plate 3 be connected with transmission mechanism, the quiet mold mounting plate 2 matched with dynamic model installing plate 3.Transmission mechanism comprises handwheel 4, the differential screw 5 be connected with handwheel 4, the nut A6 coordinated with differential screw and nut B8, and two connecting rods 7 and two connecting rod B9.Differential screw 5 is installed on base 1.Dynamic model installing plate 3 is connected by axle with connecting rod A7 and connecting rod B9; Nut A is connected by rotating shaft with connecting rod A7 and connecting rod B9 with nut B.Quiet mold mounting plate 2 is fixedly loaded on base plate 1.Nut A and be left-handed with differential screw 5 mating part screw thread, nut B and be dextrorotation with differential screw 5 mating part screw thread.
Before the utility model uses, first the stationary mould for mould of needs is connected with quiet mold mounting plate 2, dynamic model is connected with dynamic model installing plate 3, install the action of rear guarantee mould opening and closing mould accurate.
During use, as shown in Figure 2, transhipment handle 4 counterclockwise, differential screw 5 drives nut A6 and nut B8 to move to away from centerline direction, and the connecting rod be connected with nut drives the die sinking of dynamic model installing plate.After the operations such as operative employee clears up mould, spray paint, transhipment handle 4 clockwise, differential screw 5 drives nut A6 and nut B8 to moving away from centerline direction, and the connecting rod be connected with nut drives dynamic model installing plate matched moulds.In matched moulds process, because the drive characteristic of screw-nut and connecting rod are drawn close to centre, produce very large mechanical gain, finally make mould fit tightly, screw-nut has auto-lock function simultaneously, prevents the swollen type of mould.Matched moulds is poured into a mould after putting in place, and after reaching open time, the die sinking of transhipment handle 4, takes out foundry goods clockwise.Above action is repeated in the production process of product.
