Background technology
In prior art, the injecting assembly of nozzle contact device is arranged on a guiding slide, and slide drives by a lead-screw driving device, thus the action that makes injecting assembly advance, retreat under the drive of base.In the time that injecting assembly advances and contact with mould, motor continues to drive leading screw rotation that screw realization is seesawed, and the camber of spring that makes to advance and retreat produces spring force, this spring force is passed to injecting assembly by connector, leading screw, make nozzle and the mould of injecting assembly produce a contact force, to avoid generation between nozzle and mould gate to leak.Adopt the nozzle touch force of said structure to regulate by elastic constant and camber of spring stroke, but what import fixed form into due to contact force is an asymmetric power, therefore can cause larger bending moment, thereby the injection mold that causes fixed form and be fixed on above it tilts, and impact is produced; Also may cause the fracture damage of pull bar, template; Meanwhile, easily cause nozzle cannot with the tight combination of cast gate, cause injection raw material to leak.
In order to address the above problem, Granted publication number is Chinese utility model patent " injection molding machine nozzle the contact device " (application number: 201120512224.2) disclosed a kind of structure of CN202540608U, it installs respectively leading screw in the diagonal angle of barrel fixed form symmetric position, leading screw is fixed on barrel fixed form after combining with bearing, synchronous pulley is installed on wire lever, drive motors is arranged on barrel fixed form, motor drives two synchronous pulleys by Timing Belt simultaneously, on barrel fixed form, centered by leading screw, symmetry is installed fairlead and guide post, thrust plate and connecting plate are fixed respectively in two ends at two guide posts, form a connector, feed screw nut is fixed on thrust plate, connecting plate is fixed on mould fixed form after being connected with telescopic spring parts by connecting rod again, telescopic spring component movement Compress Spring produces nozzle touch force.Although said structure has solved the contact force asymmetry problem that imports fixed form into, its complex structure, not only production cost is high, also for maintenance and the maintenance of later stage machine have brought inconvenience; Meanwhile, said structure adopts the mode of leading screw and bearing combination to realize moving forward and backward of nozzle, and the installation of bearing has not only taken a large amount of installing spaces, has also increased to a certain extent production cost.
Therefore,, for the nozzle contact device of current injection machine, await doing further improvement.
Utility model content
Technical problem to be solved in the utility model is the present situation for prior art, provide a kind of can fine adjustment the nozzle contact device of nozzle touch force, the injection machine that simple in structure and production cost is low.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of nozzle contact device of injection machine, it is characterized in that: comprise and penetrate frame, gear wheel, pinion, travelling gear, reducing motor, the first screw rod and elastic component, described ejaculation is set up on the injecting assembly that is placed in injection machine; Described reducing motor is installed on the top of penetrating frame; What described gear wheel rotated is connected in ejaculation frame front side, and described pinion is meshed with gear wheel and is connected with the output shaft of reducing motor; The two side of the described ejaculation frame formation installation portion that stretches out respectively, the front side of this installation portion is installed with the travelling gear being meshed with gear wheel; Described the first screw rod has two both sides that are also symmetrically distributed in respectively injecting assembly, and rear end and the travelling gear of described the first screw rod are rotationally connected, and the front end of described the first screw rod is connected with the elastic component being arranged on mould.
As further improvement of the utility model, described elastic component comprises approach switch, floating die assembly, spring bearer plate and controller, described the first screw rod is connected with spring bearer plate by floating die assembly, the displacement of described approach switch energy perception spring bearer plate is also converted into signal and spreads out of, and described controller can receive the signal that approach switch passes on the rotating speed of controlling reducing motor.Adopt said structure, in the time that nozzle touches mould, the pulling force that installation portion is subject to is delivered on the first screw rod, the first screw rod starts mobile by floating die assembly, the spring bearer plate being connected with the first screw rod moves to the direction compressing, approach switch senses moving of spring bearer plate and is converted into movable signal and conveys to controller, controller reduces the rotating speed of reducing motor by frequency conversion, thereby make injecting assembly drive nozzle to advance with controlled speed, in the time that floating die assembly continuation compression reaches setting value, approach switch senses and signal is conveyed to controller, thereby the operation of end minus speed motor, meet the requirements of nozzle touch force, such structure can be in the time that nozzle contacts with mould, prevent contact force overshoot, avoid the damage of mould, regulate more accurately nozzle touch force.
Further, be provided with the nut matching with the external screw thread of the first screw rod on described installation portion, this nut is fixedly connected with the travelling gear of its front side.Adopt this structure, so that penetrate stable connection between frame and travelling gear.
Compared with prior art, because the first screw rod symmetry in the utility model is installed on the both sides of injecting assembly, nozzle touch force is evenly distributed; Compare with the move mode of leading screw in prior art and bearing fit, the mode that contact device of the present utility model matches with gear by the first screw rod realizes the movement of injecting assembly, this structure can regulate nozzle touch force more accurately, and due to without leading screw and bearing are installed, save the installing space that penetrates frame, reduced production cost, simultaneously, also make the structure of contact device more simple, be convenient to the maintain and repair methods in later stage.
