Title:
INJECTION MOLDING MACHINE
Document Type and Number:
WIPO Patent Application WO/2017/164420
Kind Code:
A1
Abstract:
An injection molding machine comprises: a mold attachment board to which one of a fixed mold and a movable mold is attached; a coupling board coupled to the mold attachment board with an interval placed therebetween in a mold opening/closing direction; a mold thickness adjustment mechanism that adjusts the interval to adjust mold thickness; and a control unit that controls the mold thickness adjustment mechanism. The mold thickness adjustment mechanism has a screw shaft formed in a rod that couples the mold attachment board and the coupling board to each other, a screw nut held by one of the mold attachment board and the coupling board, and a mold thickness adjustment motor that rotates one of the screw shaft and the screw nut threadedly engaged with each other. The control unit stores a reference position of a position of the screw nut relative to the screw shaft. When the position deviates from the reference position, the control unit resets the position to the reference position.
