DRIVE MECHANISM OF INJECTION MOLDING MACHINE

摘要

A drive mechanism of an injection molding machine includes a position adjustment part capable of adjusting a relative position between a rear plate and a motor fixing member. The position adjustment part includes a plurality of screw holes formed in the motor fixing member, a plurality of bolts threadedly engaged with these screw holes, and an abutting part that abuts on these bolts. These bolts are rotated to abut on the abutting part, so that the relative position between the rear plate and the motor fixing member can be adjusted.

1. A drive mechanism of an injection molding machine comprising:
a movable plate capable of advancing and retreating along a guide member; a rear plate provided in such a manner that it faces the movable plate; a ball screw including a ball screw nut and a ball screw shaft; a driving motor for driving the ball screw shaft through a coupling member; and a motor fixing member to which the driving motor is fixed, wherein the ball screw nut is fixed to the movable plate, the ball screw shaft is rotatably supported by the rear plate so as not to be movable in an axial direction, and the motor fixing member is disposed such that a relative position thereof with respect to the rear plate is adjustable, and wherein the drive mechanism of an injection molding machine further includes a position adjustment part capable of adjusting the relative position between the rear plate and the motor fixing member, and wherein the position adjustment part includes:
at least one screw hole that penetrates the motor fixing member or an extension member extending from the motor fixing member, and has a thread;a bolt threadedly engaged with the thread of the screw hole; andan abutting part that abuts on the bolt.
