These two kinds of technical schemes all attempt further to simplify the internal structure of an organization, cut down the consumption of energy, but because it is subjected to the restriction of rotary electric machine, so energy loss and mechanism's complicated problems that its motion mode conversion is brought still can not solve.
Summary of the invention
The utility model mainly be solve the existing in prior technology complex structure, energy consumption is big, precision is low etc. technical problem, the injection machine that provides a kind of employing linear electric motors simple in structure, that energy consumption is little, precision is high to drive.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of injection machine that adopts linear electric motors to drive, comprise extrusion screw rod, motor, loading hopper, cartridge heater and extrude and touch, it is characterized in that described motor is linear electric motors, the elementary of these linear electric motors is located on the linear electric motors platform, linear electric motors secondary with link to each other with extrusion die by transmission mechanism, linear electric motors secondary is provided with a push rod, this push rod is corresponding with a ball-screw, and ball screw is connected with extrusion screw rod.Linear electric motors drive the operation of the die sinking matched moulds of extrusion die.When needs drove the extrusion screw rod motion, described push rod and ball-screw connected, and drove the extrusion screw rod motion then.
As preferably, the mould-closing stroke of described linear electric motors equates with the butt joint stroke of extrusion screw rod with push rod.This design makes that push rod just in time connects with extrusion screw rod after the matched moulds process is finished, and promptly matched moulds process and docking operation are finished simultaneously, have simplified mechanism, have saved the operating time, and the process sequence compact and reasonable.
As preferably, described linear electric motors are provided with position sensor, and the signal output part of position sensor links to each other with a control module.Position sensor can record the position of motor secondary, and then draws the situation of extrusion screw rod, and control module controls to adjust according to the situation that this records.
As preferably, described linear electric motors are provided with speed sensor, and the signal output part of speed sensor links to each other with a comparator respectively with the control signal output of control module, and the signal output part of comparator links to each other with a motor driver.Motor movement speed is passed to comparator by speed sensor, comparator contrasts the speed control signal that this rate signal and control module send with advancing, and carry out velocity correction according to comparing result, because the process of this velocity correction runs through the process of whole motor movement, so this is an instant structure of proofreading and correct, and has realized the accurate control to motor speed.
As preferably, described control module is provided with a driving force control circuit and links to each other with motor driver.Matched moulds not only needs the control time also will control driving force, according to the stickiness of use plastics, mobile with decide hardening time, so driving force is to cooperate temperature control and speed to control at different material and the very important parameter adjustment of product.
The beneficial effect that brings of the present utility model is, the technical problem that solved the existing in prior technology complex structure, energy consumption is big, precision is low etc. has realized the injection machine that a kind of employing linear electric motors simple in structure, that energy consumption is little, precision is high drive.
