ABSTRACT:
A method for positioning both dies set to both movable and stationary platens of a plastic molding machine to form a cavity by fitting convex and concave portions formed on the facing surfaces of the dies into a spigot respectively, wherein a movable die is set to the movable platen at the retreat position to secure the movable die to the home position and a stationary die is temporarily clamped at the home position of the stationary platen by pressing the stationary die in the lateral direction by a repulsive member, the movable die is advanced against the stationary die under the above state, die matching of the stationary and movable dies is performed by fitting the convex portion to the concave portion, and thereby positioning of the stationary die is performed by correcting the position of the die before permanently clamping the stationary die to the stationary platen under the state in which the both dies are fastened by the movable platen. Thereby, positioning of high-accuracy dies with a small clearance of the fitting portion can be easily performed.
