PURPOSE:To cope with various molds different in mold thickness and mold opening by a method wherein the mold opening stroke is changed by setting the mold opening stroke of a movable platen is set with the aid of the position of the movable platen. CONSTITUTION:A CPU 109 for PMC, which has stored mold opening stroke, is transferred to the step SO3 so as to calculate the number of commanding pulses P for shifting a movable platen 2 from the locked-up state of molds for mold opening in order to set said number of commanding pulses through a BAC 108 to a shared RAM 103. After the number of commanding pulses for controlling the rotation of a mold clamping servomotor 7 is set to the shared RAM 103, the continuous cycles for mold opening and clamping are stated by a CPU 107 for NC, In this case, the CPU 107 for NC controls the rotation of the mold clamping servomotor 7 on the basis of the number of pulses, which are set at the shared RAM 103, in order to perform mold opening. |
