摘要： 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 17 which is provided on a frame 15 so as to be linearly movable; injection unit bases 18a and 18b which are stacked on the slide base 17 so as to be relatively movable and on which an injection unit 10 is mounted; a nozzle touch mechanism having ball screw feed mechanisms 22 and 23 for converting the rotation of a motor 21 into thrust for the slide base 17; a pivot 24 for pivotably connecting the injection unit bases 18a and 18b to the slide base 17; a pivot pin 25 for restricting the forward movement of the injection unit base 18a to switch the state of the injection unit base 18a to a pivotable state; a pin connecting portion 26, which is provided at a position, at which the pin connecting portion integrated with the injection unit base 18a is deviated from the pivot 24, for connecting the injection unit base to the pivot pin 25 so that the forward movement of the injection unit base 18a is restricted by the pivot pin 25 to be converted into a swiveling motion; a pin supporting portion 28, secured to the frame 15, for supporting the pivot pin 25 so that the pivot pin 25 is slidable in axial directions; and a pin operating portion 30 for causing the pivot pin 25 to be inserted into and extracted from the pin connecting portion 26.

摘要： A stationary platen unit and a movable platen unit each include a platen body, a load transmission portion, a die fixing plate, and a backup member. The backup member is located between the platen body and the die fixing plate. The backup member is movable between a first position in which it is in contact with both the die fixing plate and the platen body and a second position in which it is separate from the die fixing plate and/or the platen body. When a large die set is attached to the die fixing plate, the backup member is situated in the first position. When a small die set is attached to the die fixing plate, the backup member is moved to the second position.

摘要： A die drive unit has a cylinder mechanism which hydraulically drives a piston member and an additional drive mechanism which drives the piston member by means of a drive source other than a hydraulic one. A first oil chamber is formed on one side of the piston member. A second oil chamber and a third oil chamber are formed on the other side of the piston member. The first oil chamber and the second oil chamber are connected to each other by an oil passage. The piston pressure receiving area of the first oil chamber is equal to the sum of those of the second and third oil chambers.
