Description
Technical field:
The present invention relates to injection machine field, particularly a kind of quick method for adjusting mould of injection machine and adjusting device thereof.
Background technology:
Along with the development of injection industry automation, market also gets more and more to the functional requirement of injection machine.From technological angle, the function of injection machine divides beamhouse operation item and automatic cycle flow process function, preparatory function when wherein automatic mold-adjustment is exactly an injection mo(u)lding, and its target is to complete clamp force adjustment; If clamp force is not enough, mould gap can be caused, flash occurs, but can die deformation be made again too greatly, cause shorten service life, and make plastic products produce internal stress and unnecessary energy ezpenditure.
The mould adjusting mechanism of current hydraulic injection molding machine, hydraulic electric motor controls the sensitive low difference of mode transfer, and method for adjusting mould is complicated, and mode transfer precision is low, realizes clamp force accurately after cannot ensureing mode transfer; The mould adjusting mechanism of current electric injection molding machine; the rotation of general employing mode transfer bull gear drives the mode transfer screw synchronous axial system on 4 pull bars to carry out the thick adjustment of mould mould; the structure of mode transfer nut device not only affects the synchronism of mode transfer, and affects the precision of folding mould.Existing electric injection molding machine needs just can reach required clamp force through matched moulds repeatedly, die sinking, and this operation repeatedly, greatly reduces the operating efficiency of injection machine.
Summary of the invention:
The object of the invention is to solve in prior art not enough, provide the method for adjusting mould of clamp force needed for a kind of energy quick adjustment injection machine and a kind of high accuracy adjusting device, concrete technical scheme is as follows:
A quick method for adjusting mould for injection machine, is characterized in that, comprise the following steps:
S1, control moving platen move to pre-specified position; Judge that moving platen and mould have contactless, if there is contact, then perform next step; If do not contact, then continue mobile moving platen to pre-specified position;
S2, open mould, rotate mode transfer gear, adjusting yoke is retreated, thus the distance between fine setting moving platen and mould;
S3, fine setting moving platen are to reaching the clamp force preset, then mode transfer is successful; If clamp force exceedes the value not meeting or exceeding and preset, then continue to perform step S2.
Further, described pre-specified position is calculated by the clamp force preset and the elastically-deformable relation of mould.
Further, the clamp force preset described in is according to injection machine actual conditions requirements set.
Further, judge that moving platen and mould meet the mould acknowledging time pre-set with or without contact need.
Compared with prior art, the clamp force of the present invention by presetting, directly calculate pre-specified position and control moving platen and directly move to assigned address, so only need to judge that contact effectively just can directly enter fine setting mould in acknowledging time, do not need through die sinking repeatedly, matched moulds to determine assigned address, so greatly reduce the time of whole mode transfer process, improve the operating efficiency of injection machine.
Present invention also offers a kind of quick adjusting device of injection machine, it is characterized in that, described adjusting device adopts the quick mode transfer of above-mentioned method for adjusting mould, described adjusting device comprise mode transfer motor, with the gear wheel of mode transfer motor in synchrony, the encoder, meshing four mode transfer gears in gear wheel, tailgate, the mode transfer screw be installed on tailgate that synchronously count with gear wheel, the pull bar be threaded with mode transfer screw; Described four mode transfer gears are fixed on respective mode transfer screw; The other end of described pull bar is fixed on moving platen.
Further, the toggle push rod for matched moulds is also connected with between described tailgate and moving platen.
Further, described mode transfer screw is stepped, first stage is provided with screw gland, the second stage is provided with gripper shoe, in the 3rd stage, is provided with screw pad, described screw gland, gripper shoe, screw pad and tailgate are by screw compact siro spinning technology.
Further, described gear wheel is synchronous by belt with mode transfer motor.
Further, described four mode transfer gears are square and are arranged in the periphery of gear wheel.
When mode transfer, first by the flexible promotion moving platen of toggle push rod, pull bar and moving platen move to pre-specified position along with toggle push rod, when finely tuning mould, and mode transfer driven by motor bull gear drive, simultaneously encoder counts along with the rotation of gear wheel, four mode transfer gears also by while transmission, the rotation of mode transfer gear drives mode transfer screw to regulate the distance with pull bar, thus pull bar is to the certain thrust of moving platen, now bent axle push rod is motionless, and then regulates clamp force.
Compared with prior art, the present invention in gear mode transfer by the adjustment data of encoder record gear, thus the data feedback of collection is judged the whether toning of mode transfer gear to master controller, required clamp force size can be adjusted to faster, and the present invention is by screw gland, screw pad, mode transfer screw, gripper shoe and tailgate compact siro spinning technology, the firmness of mode transfer gear can be strengthened, also prevent mode transfer gear loosening in mode transfer process, have influence on the synchronism of four mode transfer gears, thus the clamp force size that impact regulates, affect the precision of mode transfer.
