Abstract
The injection driver of injection molding machine includes injection screw bolt, two frame boards with pull rod in between, slide plate on the pull rod, ball screw supported with the first ball bearing on the first frame board, ball nut on the ball screw and fastened to the slide plate, large belt wheel fixed in the end of the ball screw and connected via toothed sync belt to the small belt wheel on the first servo motor shaft, the second ball bearing set on the slide plate and connected to the tail of the injection screw bolt, and transmission mechanism in the tail of the injection screw bolt and connected to the second servo motor shaft. Under the action of the servo motor and the slide plate, the rotating injection screw bolt moves axially back or forth to inject or withdraw. The present invention has stable injection molding performance and other advantages.
Description
Technical field
The present invention relates to the injection transmission device of injection machine.
Background technology
Common injection machine adopts the hydraulic oil cylinder driving screw of injection, and variation of temperature and continuous operation make oily temperature rise, and the machine work characteristic is degenerated, and precision is difficult to keep, and influences injection speed and stop position precision simultaneously; The viscosity of oil and the elasticity of pipe-line system make to have produced non-linearly between actual issuing velocity and pressure, and control performance is degenerated, and is very big to the high speed and precision shaping influence; Oil pump motor produces noise; Hydraulic fluid leak pollutes, and fire hazardous; Complicated oil hydraulic system fault increases maintenance time and expense greatly; Produce heat, need powerful cooling system, energy resource consumption is big.
Summary of the invention
The objective of the invention is defectives such as big for the contaminated environment, the energy consumption that overcome traditional injection moulding machine hydraulic-driven injection, that speed is low, control is coarse, provide a kind of cleaning, energy consumption is little, speed is high, the injection transmission device of the injection machine of control precision.
The injection transmission device of injection machine of the present invention comprises injection screw, be enclosed within machine barrel and the hopper that is positioned at the injection screw side on the injection screw, it is characterized in that also comprising first frame plate, second frame plate, be fixed on first, pull bar between second frame plate, be enclosed within the slide plate that slides on the pull bar, ball-screw and ball nut, ball-screw passes through first group of roller bearings on first frame plate, the end of ball-screw is fixed with big belt wheel, big belt wheel links to each other with the small pulley of device on first servo motor shaft by tooth form synchronous belt, ball nut is enclosed within on the ball-screw, this ball nut and slide plate are tightened to one, on slide plate, be provided with second group of rolling bearing, the tail end of injection screw passes through second frame plate and links to each other with second group of rolling bearing, at the tail end device of injection screw the transmission mechanism that is connected with the rotating shaft of second servomotor is arranged.
During work, first servomotor of injection transmission device drives big belt wheel rotation by tooth form synchronous belt, ball-screw is also rotated, ball nut and slide plate do not rotate, but move forward or backward along pull bar according to the direction of rotation of motor, injection screw rotates under the acting in conjunction of second servomotor and slide plate on the one hand, move forward or backward vertically simultaneously, realize injection and the action of rollback backward forward.
The invention has the beneficial effects as follows that injection moulding stable performance, quick action, goods precision height, molding cycle is short, complete machine is steady, has compared the better overall performance with the common injection machine of same parameter.And, can change injection moulding speed easily by regulating the diameter ratio of large and small belt wheel.The more important thing is by servomotor to substitute original hydraulic jack that significantly reduced pollution in the injection machine manufacture process and the pollution in the use, the energy consumption during injection machine work reduces significantly.
