Mold clamping control apparatus

Abstract

A mold clamping control apparatus (49) capable of accurately generating mold clamping force is provided. The mold clamping control apparatus (49) comprises: a stationary platen (11) to which a stationary mold (15) is attached; a movable platen (34) to which a movable mold (16) is attached, the movable platen (34) being disposed to reciprocate while facing the stationary platen (11); a driver; a movement member which is moved through drive of the driver; a transmission mechanism connecting the movement member and the movable platen (34); detector for detecting the position of the movement member; memory for storing, in a relational manner, positions of the movement member during movement in accordance with a predetermined position pattern, and a mold clamping force generated at each of the positions; a mold clamping force setting device (50) for setting a mold clamping force; a mold clamping force pattern generator (51) for generating a mold clamping force pattern on the basis of the set mold clamping force; and position controller reading from the memory positions of the movement member corresponding to the mold clamping force pattern and for driving the driver on the basis of the read positions. In a mold clamping force adjustment mode, positions of the movement member during movement in accordance with a predetermined position pattern and a mold clamping force generated at each of the positions are stored in the memory in a relational manner. In a mold clamping force generation mode, positions of the movement member corresponding to the mold clamping force pattern are read from the memory.
