Abstract

PROBLEM TO BE SOLVED: To continuously execute the taking-out and the feeding of a die and to reduce the changing man-hour and the changing cost of the die by laying plural die shifting devices on a changing table. SOLUTION: The shifting device 3 for laying the die 7 newly assembled into an injection machine 75 is shifted into a carrying table while floating up under the shiftable condition by operating a handle 6a in an operating panel 6. The die 7 is fixed by interposing with a fixed plate and a movable plate. The die shifting device 3 is lowered to the shiftable lowest position by operating the operating panel 6 and the die shifting device 3 which does not lay the die, is shifted to the waiting position in the table with a drawing-out operation of the handle. An air pad is made to the negative pressure condition by operating the handle 6a in the operating panel 6, and the die shifting device is temporarily stored. The laying and the removing of the die onto the die shifting device mounted on the changing table are executed with a lifting means of a crane, etc., separately arranged.
