MOLD CLAMPING DEVICE

摘要

A mold clamping device for opening and closing a mold by a three-phase AC linear motor. The mold clamping device comprises a temperature monitoring means for monitoring the temperature of a coil for a phase most making a contribution over the acceleration of the motor during the mold feeding among the coils for three phases of the linear motor. Consequently, a defect due to the rise of the temperature of the coils of the linear motor can be properly prevented from occurring.
