A control method of an injection molding machine having a mold-clamping apparatus using a toggle mechanism, wherein the mold-clamping apparatus of the injection molding machine comprises a frame, a stationary platen as a stationary mold support apparatus fixed to the frame, and a toggle support as a base plate movably arranged relative to the frame with a predetermined distance from the stationary platen, wherein the toggle support functions as a toggle type mold-clamping apparatus support apparatus, wherein a plurality of tie bars as guiding means extend between the stationary platen and the toggle support, wherein a movable platen is arranged opposite to the stationary platen and functions as a movable mold support apparatus movably arranged forward and backward along the tie bars, wherein a mold apparatus is comprised of a stationary mold and a movable mold, and wherein the stationary mold is attached to a mold attaching surface of the fixed platen opposite to the movable platen, the control method comprising: adjusting a mold-clamping force by moving a fixing position of a toggle support of the mold-clamping apparatus so as to be close to a target mold-clamping force; acquiring a mold clamping force detection value by detecting an actual mold-clamping force by driving said mold-clamping apparatus; acquiring a difference between the mold-clamping force detection value and said target mold-clamping force; acquiring the mold-clamping force detection value, when the difference exceeds a predetermined value, by performing mold-clamping by slightly moving a position of the toggle support until the difference becomes equal to or smaller than a predetermined value, and repeating the operation of acquiring the difference from said target mold-clamping force; and correcting a setting of a molding condition position in accordance with an amount of movement of said toggle support; wherein said molding condition position is a mold protection position, wherein the mold protection position is a position immediately before the movable mold contacts the stationary mold at a mold touch position, wherein the mold protection position is corrected with the position of the movable platen at this time as the mold touch position; or wherein said molding condition position is a core setting position when performing a core compression molding which compresses a molded product by driving a core to form a cavity space forward and backward. adjusting a mold-clamping force by moving a fixing position of a toggle support of the mold-clamping apparatus so as to be close to a target mold-clamping force; acquiring a mold clamping force detection value by detecting an actual mold-clamping force by driving said mold-clamping apparatus; acquiring a difference between the mold-clamping force detection value and said target mold-clamping force; acquiring the mold-clamping force detection value, when the difference exceeds a predetermined value, by performing mold-clamping by slightly moving a position of the toggle support until the difference becomes equal to or smaller than a predetermined value, and repeating the operation of acquiring the difference from said target mold-clamping force; and correcting a setting of a molding condition position in accordance with an amount of movement of said toggle support; wherein said molding condition position is a mold protection position, wherein the mold protection position is a position immediately before the movable mold contacts the stationary mold at a mold touch position, wherein the mold protection position is corrected with the position of the movable platen at this time as the mold touch position; or wherein said molding condition position is a core setting position when performing a core compression molding which compresses a molded product by driving a core to form a cavity space forward and backward. wherein said molding condition position is a mold protection position, wherein the mold protection position is a position immediately before the movable mold contacts the stationary mold at a mold touch position, wherein the mold protection position is corrected with the position of the movable platen at this time as the mold touch position; or wherein said molding condition position is a core setting position when performing a core compression molding which compresses a molded product by driving a core to form a cavity space forward and backward.
