Abstract
A mold clamp control method for an injection molding machine having a toggle-type mold clamping mechanism. The mold clamp control method includes: a low-pressure mold clamping step that performs position hold control by which a crosshead is held in a set holding position in a state where a toggle link has been bent, when injection-filling is started; and a compression-press step that performs speed and position control by which the crosshead is advanced toward a set advancement position from the set holding position in a state where a first output upper limit value has been provided to a driving section. Advancement of the crosshead is continued in at least part of the compression-press step in a state where a generated output of the driving section is maintained at the first output upper limit value.
