Abstract
A brake control method for an injection molding machine includes the steps of obtaining mold clamping force information indicating the mold clamping force of a mold opening/closing mechanism and determining whether or not the mold clamping force of the mold opening/closing mechanism exceeds a predetermined value, based on the mold clamping force information. When the mold clamping force of the mold opening/closing mechanism does not exceed the predetermined value and when a servo amplifier cuts off the supply of power to a servomotor that drives the mold opening/closing mechanism, a brake mechanism for applying braking force to the mold opening/closing mechanism is actuated. On the other hand, when the mold clamping force of the mold opening/closing mechanism exceeds the predetermined value, the brake mechanism will not be actuated.
