Description
Technical field
The invention belongs to mould applications, be specifically related to a kind of Servo Injection Molding Machine.
Background technology
In injection machine, powder is filled into the cavity space between fixed mould and moveable die from the injection nozzle injection of injection device, and makes it solidify, obtain formed products thus.Further, carrying out mold closing, matched moulds and die sinking to make moveable die move relative to above-mentioned fixed mould, being equipped with mold closing mechanism.
In this mold closing mechanism, the mold closing mechanism that there is the fluid pressure type by driving for oil supply hydraulic cylinder and the DYN dynamic mold closing mechanism driven by motor, Driven by Hydraulic Cylinder, oil condition is leaked in easy appearance, the controlling of DYN dynamic mold closing mechanism is higher, can not pollute periphery and energy efficiency is higher, so more used.In this case, by drive motor, ball-screw rotated and produce thrust, and by elbow type mechanism, this thrust being amplified, producing larger mold clamping force.
But in the DYN dynamic mold closing mechanism of above-mentioned formation, owing to using elbow type mechanism, so in the characteristic of this elbow type mechanism, be difficult to change mold clamping force, response and less stable, can not control mold clamping force in formation.Therefore, the mold closing mechanism that the thrust produced by ball-screw directly can be used as mold clamping force is provided.In this case, due to the torque of motor and mold clamping force in direct ratio, so mold clamping force can be controlled in formation.
But, in above-mentioned existing mold closing mechanism, not only the load resistance of ball-screw is lower, and mold clamping force can change due to the torque ripple occurred in the motor, when causing matched moulds there is parameter in stroke distances, even if stroke distances difference 1mm, mold clamping force may differ nearly 1 ton.
Summary of the invention
For deficiency of the prior art, the invention provides a kind of Servo Injection Molding Machine, solve servomotor mold clamping force and control bad, easily occur the problem that travel displacement deviation is little and mold clamping force is inadequate.
The present invention is achieved through the following technical solutions.
A kind of Servo Injection Molding Machine, comprise fixed half and moving half, described dynamic model passes through driven by servomotor, be provided with clamping controller between described dynamic model and servomotor, described clamping controller comprises movable plate and fixed head, and described fixed head is fixedly connected with dynamic model, guide post is provided with between described movable plate and fixed head, described guide post is provided with spring, and described spring one end bear against movable plate, and the other end bear against fixed head.When the cover half before solving and dynamic model matched moulds, the clamp force difference that the fine displacements deviation that driver part exists causes is huge, after spring-compressed, there is energy, even if servomotor stops, nut on movable plate and between ball-screw due to oblique threaded engagement, have the self-lock force of high strength, the clamp force between fixed half and moving half can accurately control.
As preferably, described movable plate and the both sides of fixed head are provided with housing, and the both sides of described movable plate are provided with optical sensor, and described housing is the sheet metal component of strip, one end is fixedly installed on fixed head, and the other end and optical sensor keep the distance of 50 millimeters.Vibrational power flow is simply ingenious, the susceptibility of light sensing is high, distance is utilized to hide the principle of sensor emission pole, realize the object into locating tab assembly displacement, sheet metal component can make the different multiple modules of light transmittance, after self-locking, if the change of dynamic model generation micro-displacement simultaneously, from the chip of the output of optical inductor, the data of reading can show on a player.
As preferably, described servomotor connects ball-screw, and described ball-screw passes from movable plate, movable plate is provided with the nut coordinated with ball-screw.Utilize coordinating of ball-screw and movable plate top nut, movable plate is as slave unit, ball-screw is the actuated element that machine tool and precision optical machinery the most often use, its major function converts rotary motion to linear movement, or change torque axis into axial repeated action power, have high accuracy, invertibity and high efficiency feature concurrently simultaneously.
As preferably, described dynamic model is also provided with scraping wings, described scraping wings front end is also provided with charging ram, and described scraping wings is by the air cylinder driven at its rear.
Compared with prior art: spring has screen resilience, effectively can pin mold clamping force, even if the displacement tolerance of dynamic model is comparatively large, its mold clamping force also can not vary widely, and matched moulds is effective, decreases production cost.
