Abstract:
A position setting method for a movable mold of a motor-driven injection molding machine, comprising:detecting a position of a crosshead which is driven by a servo-motor; preliminarily storing correspondence between positions of the crosshead and positions of the movable mold, which is coupled to the crosshead via a link mechanism, in a memory table; and obtaining a position of the movable mold based on the detected position of the crosshead by referring to the memory table, wherein the obtaining comprises: reading out from the memory table, when a position of the crosshead corresponding to a target position of the movable mold is not stored in the memory table, two positions of the crosshead corresponding to two positions of the movable mold, between which the target position lies; and calculating a value of an intermediate position between the two positions of the crosshead.
