Abstract
The invention discloses a servo drive and control system of an injection molding machine, and relates to the technical field of servo drive and control of injection molding machines. The system comprises a main engine control computer, a dosing pump, a servo motor, a load pressure sensor and an encoder, wherein the encoder is arranged on the servo motor for driving the dosing pump; the operation condition of the dosing pump is transmitted to the main engine control computer through the load pressure sensor; and a command of the main engine control computer is sent to the servo motor by the encoder. The system enables the operation power of the servo motor and the load demand power to be completely matched through change to achieve an energy saving effect; compared with traditional hydraulic plastic injection molding equipment, the system generates no powerless energy consumption caused by the pressure and flow adjustment of a hydraulic system.
Description
, art
The present invention relates to a kind of injection machine servo-drive and control technology field, particularly relate to a kind of injection machine servo-drive and control system.
, background technology
The technology that conventional hydraulic formula plastic-injection moulding machine extensively adopts Induction Motor-Driven constant displacement pump to combine with electro-hydraulic proportional valve, cause a large amount of idle energy consumption because constant displacement pump exports constant flow rate, energy consumption is very high.
, summary of the invention
The object of this invention is to provide one and make that servomotor operate power and load demand power are intact to be mated, reach injection machine servo-drive and the control system of energy-saving effect.
The technical solution adopted for the present invention to solve the technical problems is: it comprises host computer control computer, constant displacement pump, servomotor, load pressure sensor, encoder, encoder is arranged on servomotor and drives constant displacement pump, constant displacement pump working order is sent to host computer control computer by load pressure sensor, and the order of host computer control computer is sent to servomotor by encoder.
The invention has the beneficial effects as follows, this practical technology makes by change that servomotor operate power and load demand power are intact to be mated, reach energy-saving effect, compared with equipping with conventional hydraulic formula injection-moulding plastic, no longer produce the idle energy consumption because hydraulic system pressure, Flow-rate adjustment cause.
, accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
, detailed description of the invention
In FIG, the present invention is arranged on servomotor 3 by encoder 5 and drives constant displacement pump 2, constant displacement pump 2 working order is sent to host computer control computer 1 by load pressure sensor 4, the program of host computer 1 is sent to servomotor 4 by encoder 5, control rotating speed and the moment of torsion of servomotor 3, thus realize hydraulic system pressure and flow double-close-loop control, servomotor 3 operate power is mated with constant displacement pump 2 load demand power is intact, reaches energy-saving effect.
