Abstract
There is provided an apparatus capable of smoothly swiveling an injection unit of medium or large motor-driven injection molding machine. The apparatus comprises: a slide base which is provided on a frame so as to be linearly movable; injection unit bases and which are stacked on the slide base so as to be relatively movable and on which an injection unit is mounted; a nozzle touch mechanism having ball screw feed mechanisms and for converting the rotation of a motor into thrust for the slide base ; a pivot for pivotably connecting the injection unit bases and to the slide base ; a pivot pin for restricting the forward movement of the injection unit base to switch the state of the injection unit base to a pivotable state; a pin connecting portion , which is provided at a position, at which the pin connecting portion integrated with the injection unit base is deviated from the pivot , for connecting the injection unit base to the pivot pin so that the forward movement of the injection unit base is restricted by the pivot pin to be converted into a swiveling motion; a pin supporting portion , secured to the frame , for supporting the pivot pin so that the pivot pin is slidable in axial directions; and a pin operating portion for causing the pivot pin to be inserted into and extracted from the pin connecting portion
