Abstract
The utility model discloses an electric demoulding system on a hydraulic injection moulding machine. The electric demoulding system on the hydraulic injection moulding machine is characterized by comprising a demoulding mechanism, a controller, a servo motor and a servo driver, wherein the controller comprises a central processing unit (CPU) module and a bus communication interface module; the CPU module is electrically connected with the bus communication interface module; the bus communication interface module is electrically connected with the servo driver; the servo driver is electrically connected with the servo motor; an encoder is arranged in the servo motor; the servo motor drives the demoulding mechanism through a transmission mechanism to do linear motion. The electric demoulding system on the hydraulic injection moulding machine has the advantages that the electric system is adopted on the hydraulic injection moulding machine to control the demoulding mechanism to do linear motion, so compared with the traditional hydraulic driving system, the electric demoulding system is low in energy consumption, low in noise and environment-friendly; the encoder is arranged in the servo motor, and a position signal of the demounding mechanism is fed back to the controller in real time through the encoder, so the positioning precision is high.
Description
Technical field
The utility model relates to a kind of hydraulic injection molding machine, relates in particular to the electronic dismoulding system on a kind of hydraulic injection molding machine.
Background technology
Along with the continuous expansion of plastic products application in recent years, in the world the demand of injection machine has been presented to lasting, unprecedented soaring trend.At present injection machine mainly can be divided into two kinds of full electric injection molding machine and hydraulic injection molding machines; and mould emptier (being ejecting mechanism) in hydraulic injection molding machine substantially all adopts hydraulic system as the power source that drives mould emptier at present; its energy consumption is high, easy oil leakage, not environmental protection; and precision is low; be difficult to link with die sinking action, inefficiency.
Summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of energy consumption is low, noise is little, the electronic dismoulding system on environmental protection and the high hydraulic injection molding machine of control accuracy.
The utility model solves the problems of the technologies described above adopted technical scheme: the electronic dismoulding system on a kind of hydraulic injection molding machine, comprise mould emptier, controller, servomotor and servo-driver, described controller comprises CPU module and bus communication interface module, described CPU module is electrically connected to described bus communication interface module, described bus communication interface module is electrically connected to described servo-driver, described servo-driver is electrically connected to described servomotor, described servomotor is built-in with encoder, described servomotor drives described mould emptier to carry out rectilinear motion by transmission mechanism.
Described transmission mechanism comprises ball-screw and feed screw nut; described ball-screw is fixedly connected on the driving shaft of described servomotor; described feed screw nut is fixedly connected with described mould emptier, described ball-screw and described feed screw nut bolt.
Described servomotor is AC permanent magnet synchronous motor, and the drive current of described servo-driver is alternating current.
Compared with prior art, the utility model has the advantages that owing to adopting power driven system to control mould emptier on hydraulic injection molding machine and carry out rectilinear motion, compare with traditional fluid power system that its energy consumption is low, noise is little and environmental protection; And because servomotor is built-in with encoder, the position signalling by encoder Real-time Feedback mould emptier is to controller, its positioning precision is high.
