Description
Technical field
The invention belongs to mould applications, and in particular to a kind of Servo Injection Molding Machine.
Background technology
In injection machine, powder is injected from the injection nozzle of injection device and fixing mould and But moving die is filled into
In cavity space between tool, and solidify it, thus obtain formed products.Also, in order that moveable die is solid relative to above-mentioned
Fixed mold moves and carries out mold closing, matched moulds and die sinking, is equipped with mold closing mechanism.
In the mold closing mechanism, there is mold closing mechanism, the Yi Jiyou of the fluid pressure type by supplying oil to hydraulic cylinder and driving
The DYN dynamic mold closing mechanism of motor driving, Driven by Hydraulic Cylinder, the situation for oil leak easily occur, DYN dynamic mold closing mechanism
Controlling is higher, will not pollute periphery and energy efficiency is higher, so more being used.In this case, by driving electricity
Motivation makes ball-screw rotate and produce thrust, and is amplified the thrust by elbow type mechanism, produces larger mold clamping force.
However, in the DYN dynamic mold closing mechanism of above-mentioned composition, due to using elbow type mechanism, so in the elbow type mechanism
Characteristic on, it is difficult to change mold clamping force, response and less stable, mold clamping force can not be controlled in formation.It thus provides
The thrust produced by ball-screw can be directly used as to the mold closing mechanism of mold clamping force.In this case, due to motor
Torque is in direct ratio with mold clamping force, 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 relatively low, and due to electronic
The torque ripple that occurs in machine and mold clamping force can change, the presence parameter of stroke distances when causing matched moulds, even if stroke distances phase
Poor 1mm, may differ nearly 1 ton on mold clamping force.
The content of the invention
For deficiency of the prior art, the present invention provides a kind of Servo Injection Molding Machine, to solve servomotor mold clamping force control
System is bad, easily occur that travel displacement deviation is small and the problem of inadequate mold clamping force.
The present invention is achieved through the following technical solutions.
A kind of Servo Injection Molding Machine, including fixed half and moving half, described dynamic model are driven by servomotor, described dynamic model and
Clamping controller is provided between servomotor, described clamping controller includes movable plate and fixed plate, and described consolidates
Fixed board is fixedly connected with dynamic model, is provided with guide rod, described guide rod and is provided between described movable plate and fixed plate
Spring, described spring one end bear against movable plate, and the other end bear against fixed plate.Cover half and dynamic model matched moulds before solving
When, the clamp force difference caused by the fine displacements deviation that driving part is present is huge, has energy after spring-compressed, even if watching
Motor is taken to stop, because oblique screw thread coordinates between the nut and ball-screw on movable plate, the self-lock force with high intensity, cover half
Clamp force between dynamic model can be controlled accurately.
Preferably, described movable plate and the both sides of fixed plate are provided with housing, the both sides of described movable plate are set
There is optical sensor, described housing is the sheet metal component of strip, and one end is fixedly installed in fixed plate, the other end and optical sensor
The distance of 50 millimeters of holding.Structure setting is simply ingenious, and the susceptibility of light sensing is high, and sensor emission pole is covered using distance
Principle, realizes the purpose into locating tab assembly displacement, while the different multiple modules of light transmittance can be made on sheet metal component, in self-locking
Afterwards, if micro-displacement change occurs for dynamic model, from the chip of the output end of optical inductor, the data of reading can be shown in player
On.
Preferably, described servomotor connection ball-screw, described ball-screw is passed through from movable plate, mobile
The nut coordinated with ball-screw is provided with plate.Using the cooperation of ball-screw and movable plate top nut, movable plate as from
Dynamic component, ball-screw is actuated element most-often used on machine tool and precision optical machinery, and its major function is by rotation fortune
Dynamic conversion linear movement, or moment of torsion is converted into axial repeated action power, while having high accuracy, invertibity and efficient concurrently
Feature.
Preferably, being additionally provided with scraping wings on described dynamic model, described pusher front edge of board is additionally provided with charging ram,
Described scraping wings is driven by the cylinder at its rear.
Compared with prior art：Spring has screen resilience, can effectively pin mold clamping force, even if the displacement tolerance of dynamic model
Larger, its mold clamping force there will not be very big change, and matched moulds effect is good, reduces production cost.
