The utility model content
The purpose of this utility model is to provide a kind of simple and reasonable, easy and simple to handle, compact conformation, volume is little, closing precision is high, energy consumption is low, but the injection machine of intensity high speed shifting formwork and quick high-pressure locked mode rotates the supercharging clamping mechanism, to overcome weak point of the prior art.
A kind of injection machine by this purpose design rotates the supercharging clamping mechanism; be connected with lock die plate, moving die plate, supporting plate, oil hydraulic cylinder and tailgate on the guide pillar in turn; be provided with charged piston in the oil hydraulic cylinder; be provided with between moving die plate and the fore-set and eject oil cylinder, its architectural feature is to be provided with between charged piston and the fore-set to rotate the supercharging clamping mechanism.
Above-mentioned rotation supercharging clamping mechanism comprises and is arranged on intermeshing internal tooth and external tooth between charged piston and the fore-set, and the come in and go out hydraulic stem end of lock oil cylinder, charged piston side and is hinged.Be provided with the fore-set backing plate between charged piston and the fore-set, adopt bolt affixed between fore-set backing plate and the fore-set, be respectively arranged with intermeshing six pairs of internal tooths and external tooth on charged piston end and the fore-set backing plate, charged piston rotates 30 ° of angles around the charged piston center under the hydraulic stem of the lock oil cylinder of coming in and going out promotes.Charged piston is under the hydraulic stem of the lock oil cylinder of coming in and going out promotes, and after the charged piston center was rotated 30 °, external tooth on internal tooth on it or external tooth and the fore-set backing plate or internal tooth linearly rigidity joined.The lock oil cylinder other end of coming in and going out is hinged on frame or the oil hydraulic cylinder shell.The moving die plate two sides are provided with rolling bearing, are provided with the guiding self-lubricating bearing between moving die plate and its directed guide pillar.Be provided with fairlead between supporting plate and the fore-set.
The utility model adopts charged piston and the structure of rotating the flashboard one, uniform six internal tooths on its circumferential end surfaces, and the backing plate that is connected with the fore-set afterbody is provided with six external tooths; During work, during high-voltage lock mould, charged piston moves forward while rotating under the hydraulic stem of the hydraulic oil and the lock oil cylinder of coming in and going out promotes, and realizes quick supercharging, and during die sinking, charged piston moves backward while rotating, and realizes quick die sinking.
The utility model is with charged piston and rotation flashboard integral structure, and the flashboard anglec of rotation is designed to 30 °, and its lock stroke of coming in and going out shortens; Because the charged piston shift motion shortens, the hydraulic oil volume in the high-voltage oil cylinder reduces, and can realize supercharging fast in the short time; When its rapid mould-moving, owing to charged piston need not to move together, so the energy consumption of press moulding mechanism reduces; Because moving die plate adopts rolling bearing supporting and low friction self-lubricating bearing guiding, when press moulding mechanism moved, resistance reduced; The lock die plate adopts the iso-stress structure, and the deflection of a plate is little.
The utility model is simple and reasonable, easy and simple to handle, compact conformation, volume is little, closing precision is high, energy consumption is low, intensity is high, can realize high speed shifting formwork and quick high-pressure locked mode.
