Description
Technical field
The utility model relates to a kind of resetting means, particularly relates to injection mold thimble resetting-mechanism.
Background technology
Because glue camera bellows series of products order volume is large, mould utilization rate is high, causes this serial die often occur mould therefore keep in repair, and wherein keeping in repair maximum problem points is exactly that the oblique top matched moulds that do not reset causes fracture.Every mold return pin of this series is all equipped with four springs, except using spring and repeatedly ejecting, also ejects back center plate for product and utilizes spring enforced reset.But this product requirement ejects distance, all exceed the greatest limit that spring uses at every turn, greatly reduced the service life of spring.Once occur that spring breakage or other reasons cause the non-return of ejector retainner plate, spring just lose protection oblique top function, mould then by force matched moulds cause oblique top to rupture, cause great trouble to subsequent maintenance.
Utility model content
The purpose of this utility model is to solve because rely on spring to reset to ejector retainner plate, repeatedly utilize spring reset, spring can because be subject to alternate stress, and rupture, ejector retainner plate is so caused not reset, and utilizing the motion of dynamic model to push back oblique top, agreement is also difficult to the problem returning to due reset position.
In order to solve the problem, the utility model proposes a kind of injection mold thimble resetting-mechanism, comprise dynamic model and cover half, dynamic model and cover half snap together, ejector retainner plate is positioned at dynamic model in cover half opposite side, oblique top one end is fixedly connected on ejector retainner plate, the other end prolongs to tilt to extend in direct acting mould, also comprise fixed block, fixed block is fixedly connected on ejector retainner plate, power rail along the moving direction of dynamic model being fixed on cover half, also fit by extension and fixed block, performing bar one end is rotatably connected on dynamic model, the other end tilts to extend straight fixed block and power rail joint place, and fit with fixed block and power rail.
The injection mold thimble resetting-mechanism of such scheme is the completing of making when fixed half and moving half fastens making, after fixed half and moving half fastens, ejector retainner plate fixes fixed block, power rail along the moving direction of dynamic model being fixed on cover half, also fit by extension and fixed block, performing bar one end is rotatably connected on dynamic model, the other end tilts to extend straight fixed block and power rail joint place, promote to perform bar at the process medium power bar of matched moulds, perform bar to rotate around fixing point, perform the hypotenuse of bar and fixed block in rotation process to utilize after fitting at first and perform bar seamed edge and cause fixed block to drive ejector retainner plate to move toward die sinking direction to promote fixed block, reach the reset of thimble, due to power rail, performing between bar and fixed block is the outside being fixedly connected on mould, make power rail, perform the maintenance of modification that bar and fixed block cause in ejector retainner plate reseting procedure or breakage etc. with changing conveniently.Final process simultaneously after matched moulds performs the angle that bar is positioned at fixed block and power rail formation, can reduce in transmission process and reduce ejector retainner plate by the component perpendicular to the direction of motion, thus reduce the inclination of ejector retainner plate.
Further optimization, power rail and perform boom end semicircular arc, circular arc at power rail and to perform between bar in position relationship process because there is the sudden change that Non-smooth surface transition causes.
Further optimization, guide to be fixed on dynamic model and to fit with power rail, and power rail is long, in order to power rail reduces its deflection, and and can perform between bar and provides fulcrum because stress deformation causes bending for power rail, reduce the distortion performing bar.
Further optimization, power rail, performs bar and fixed block and sets up separately with on two relative sides on mould, can avoid ejector retainner plate mould on opposite sides by force unbalance.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the utility model mould-matching structure schematic diagram;
Fig. 2 is the utility model mold-opening structure schematic diagram;
Mark in above-mentioned figure is: cover half 1, power rail 11, dynamic model 2, execution bar 21, oblique top 22, ejector retainner plate 23, fixed block 24, guide 3, cover half frame 4, dynamic model frame 5.
Detailed description of the invention
The utility model injection mold thimble resetting-mechanism, resetting at traditional injection mold thimble is by setting up spring between ejector retainner plate 23 and dynamic model 2, the piston rod of cylinder is connected with at moving platen 2, cylinder is fixed on dynamic model frame 5 at cover half 1 and dynamic model 2, in matched moulds process, utilize spring by ejector retainner plate 23 by injection mold thimble resetting-mechanism after matched moulds, as shown in Figure 1, dynamic model 1 is fixed on cover half frame 3, dynamic model 2 is fixed on dynamic model frame 4, oblique top up and down 22 in dynamic model 2 is fixed on ejector retainner plate 23, connection fixing block 24 on ejector retainner plate 23, cover half 1 is fixed with power rail 11 by two bolt levels, power rail 11 horizontally contacts with fixed block 24 after right extension, dynamic model 2 by a bolt be rotatably connected perform bar 21, the one end performing bar 24 extends to the contact position of fixed block 24 and power rail 11, bolt on dynamic model 2 is fixed with power rail 11 to the guide 3 cut.
After die sinking, injection mold thimble resetting-mechanism as shown in Figure 2, dynamic model 2 moves right, ejector retainner plate 23 is released left being connected under the effect of the liquid presses piston pole on ejector retainner plate 23 at hydraulic cylinder, in the process that ejector retainner plate 23 is pushed out, power rail 11 separates with execution bar 21, fixed block 24 is separated with power rail 11, after dynamic model 2 is separated completely with cover half 1, performs bar 21 vertically sagging.
The utility model injection mold thimble resetting-mechanism is the rear making at dynamic model 1 and the 2-in-1 mould of cover half, first fixed block 24 is fixed at the centre position bolt of ejector retainner plate 23, cover half 1 is fixed with the power rail 11 tangent with fixed block 24 by two bolt levels, connection during dynamic model 2 can be turned by a bolt performs bar 21, the one end performing bar 21 extends to fixed block 24 and the tangent place of power rail 11, performs bar 21 and fixed block 24 and power rail 11 tangent.
Power rail 11, perform bar 21 and fixed block 24 location arrangements on mould on two relative sides.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; without departing from the concept of the premise utility; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
