A composite insulator mandrel to be injected is arranged inside a lower die of the injection machine. Tow ends of the mandrel, which stretching out of the injection machine, are supported by the insulator supporting devices, when the mandrel is injected, the movable stander of the synchronizer is driven by a hydraulic oil cylinder to synchronously ascend with the lower die of the injection machine, the eccentricity caused by the injection can be avoided, and the quality of a composite insulator can be guaranteed. The forced synchronization mechanism can guarantee the levelness of the long movable stander in the ascending process, the gnawing and seizing phenomenon of a guide pillar and a guide sleeve can be avoided, and the working reliability and the long service life of the synchronizer can be guaranteed.
Description
Technical field
The present invention relates to a kind of composite insulator injector, particularly a kind of composite insulator injector synchronizer.
Background technology
Insulator is for the tenaculum electric conductor and makes the electric elements of its insulation, and it is widely used in electric power system.In the production technology of composite insulator, need plug is placed on the injection moulding of carrying out umbrella sheath in the insulator injection machine, because the length of extra-high voltage combined insulator is longer, length is between 2-12 rice, because the size restrictions of injector mould needs to adopt the stage injection moulding, when carrying out stage injection, the part plug stretches out the mould of injector, easily causes product eccentric under Action of Gravity Field, affects product quality.And plug intensity after injector is heated descends, and easily causes to fracture.
Summary of the invention
The technical problem to be solved in the present invention provides the composite insulator injector synchronizer that a kind of support effect is good, be difficult for off-centre when injecting.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of composite insulator injector synchronizer, its innovative point is to comprise: a movable machine frame, but slidely connect the insulator bracing or strutting arrangement that several along continuous straight runs move on the described movable machine frame, described insulator bracing or strutting arrangement comprises base for supporting, Support bracket and adjusting screw(rod), the base for supporting bottom is equipped with guide wheel, guide wheel drops in the horizontal guide rail of movable machine frame, Support bracket is installed on the base for supporting, the bottom of described Support bracket is provided with a pair of adjusting screw(rod) that passes vertically downward base for supporting, is threaded on the adjusting screw(rod) to regulate the stop nut of height; One fixed frame, this fixed frame is arranged on the below of movable machine frame, the driving mechanism of a pair of driving movable machine frame vertical lift is installed on the fixed frame, described driving mechanism is vertically disposed hydraulic jack, and between fixed frame and movable machine frame four jiaos, the guide pillar guide sleeve structure being set, the bottom of fixed frame is equipped with the universal wheel of strap brake sheet and the fast pulley of strap brake sheet; Be provided with forced synchronism mechanism between described fixed frame and the movable machine frame, forced synchronism mechanism comprises rocking bar, lower rocking bar and connecting rod, rocking bar on hinged two on the movable machine frame, be hinged with the two lower rocking bars corresponding with upper rocking bar on the fixed frame, corresponding upper rocking bar lower end and lower rocking bar upper end are hinged, connect by connecting rod between the pin joint of two pairs of upper and lower rocking bars.
The invention has the advantages that: during use, synchronizer is arranged on the both sides of injector, its insulator bracing or strutting arrangement is adjusted to the counterdie of injector and flushes, and composite electric insulator core bar to be injected is placed in the counterdie of injector.Plug stretches out the two ends of injector and is supported by the insulator bracing or strutting arrangement, during injection, the counterdie of injector rises and moves matched moulds to patrix, simultaneously, the movable machine frame of synchronizer rises under the driving of hydraulic jack synchronously, so that plug rises overally, cause off-centre when avoiding injecting, guarantee the compound inslation protonatomic mass.Forced synchronism mechanism can guarantee the levelness of the long movable machine frame of length when rising, and avoids the guide pillar guide pin bushing to gnaw biting, stuck phenomenon, guarantees the functional reliability of synchronizer and long useful life.
