Definitions

  • the present invention relates to an injection molding machine, and in particular, performs an injection by moving a screw in a transfer direction, and rotates the screw to perform measurement * kneading. -This is related to the screw rotation mechanism in the drive mechanism.
  • a screw driving device of an injection molding machine which needs to rotate a screw is a combination of a screw and a means for tilling the screw by a spline connection.
  • the spline shaft is attached to the screw shaft.
  • the spline shaft and the spline-coupled gears and the like were driven by a motor via a transmission mechanism to rotate the screw.
  • screw drives have been developed that use a servomotor to move the screw in the axial direction and perform injection.
  • the equipment was made expensive because the spline shaft was required for the 10-axis pulley.
  • An object of the present invention is to provide a screw rotation mechanism that can rotate a screw without using it.
  • a motor is fixed to a pusher plate, and a screw shaft is mounted on the pusher plate so as to be rotatable and unable to move in the axial direction.
  • a transmission for rotating the screw is provided on the motor shaft of the motor and the screw shaft.
  • FIG. 1 is a sectional view of an essential part of an embodiment of the present invention.
  • the pusher plate 1 is configured to be driven in the left and right directions in the figure by injection driving means (not shown).
  • the pole nut can be freely rotated and axially moved to the above-mentioned push rate plate 1. It is mounted on the front plate and the rear plate ⁇ fixed to the base of the injection molding machine so that it is rotatable and cannot move in the axial direction:
  • the ball nut is screwed into the pole screw, and the ball screw is driven and rotated by the injection servo motor, and the push rate 1 is driven right and left in the figure, and the push rate 1 is shown in the figure. Drive left and right.
  • the above pusher plate 1 may be driven to the left and right in the figure using hydraulic pressure.
  • the mechanism for injecting by moving the prism rate in the left-right direction in the figure is not the gist of the present invention, and details will be omitted.
  • Screw shaft 2 with screw at the end
  • the screw leave 3 is rotatably supported by the radial bearing 8 on the above-mentioned push-shape plate 1, and the other end of the screw sleep 3 is fixedly supported by a bolt 7. Stop supported by thrust bearing 10 via material 9 and fixed to port 7 by pusher plate 1
  • a pusher plate 1 is provided with a screw rotation, that is, a kneading thermomotor 12, which is fixed by a port 7.
  • a pulley 14 is fixed to the motor shaft 13 of the second motor.
  • a toothed pulley 15 is fixedly attached to the screw thread 3, and a timing belt 16 is interposed between these two toothed pulleys. Is erected.
  • the driving of the servo motor 12 is stopped, the injection driving means is driven to move the pusher plate 1 to the left in the drawing, and the injection is performed by the injection means described above.
  • a drive source such as an injection servomotor is driven, a ball screw is rotated, and a push sharp is inserted through a nut (not shown) which is combined with the pole screw fixed to the push rate 1. Move the rate 1 to the left in the figure, and move the screw shaft 2 through the stopper 11, thrust bearing 10, support member 9, and screw leave 3. Move to the middle left and perform injection.
  • a predetermined back pressure is applied by a drive source such as the injection servomotor, etc., and the metering ⁇ the kneading servomotor 12 is driven.
  • the rotation of the shaft 13 is transmitted to the screw leave 3 via the pulley 14, the timing belt 16, and the pulley 15 to rotate the screw shaft 2. Let it.
  • the resin is melted by the rotation of the screw shaft 2, and when the back pressure generated by the melting becomes higher than the back pressure set for the drive source of the injection motor or the like, the screw is screwed.
  • the key is pressed backward, and the push rate 1 is retracted to the right in the figure.
  • the rotation of the servo motor 12 may be transmitted to the screw shaft 2 by gear transmission instead of the transmission device by the pulleys 14 and 5 and the timing belt 16.

Abstract

Un mécanisme d'entraînement de la vis d'une machine de moulage par injection permet de réduire le coût de la machine lorsqu'un couplage à cannelures est utilisé pour coupler un arbre de la vis avec un dispositif de mise en rotation dudit arbre. Un moteur (12) est attaché à un plateau de pression (1) qui porte de façon rotative un arbre de la vis (2) mais qui ne permet pas à l'arbre de la vis (2) de se déplacer axialement. Des unités de transmission (14, 15, 16) sont agencées entre un arbre moteur (13) et l'arbre de la vis (2) pour mettre l'arbre de la vis (2) en rotation.
