Abstract
An mold thickness adjustable range S of a link housing included in a toggle type clamping unit for a thick mold of the greatest allowable thickness and that of the same for a thin mold of the smallest allowable thickness is divided into a plurality of sections. Extra elongations by which tie bars included in the toggle type mold clamping system are to be stretched for desired mold clamping forces are determined beforehand and are assigned to the sections of the mold thickness adjustable range S. One of the sections in which the link housing is positioned when the toggle type mold clamping system is set in a lock-up state in which a movable half mold is in contact with a fixed half mold is specified by a combination of binary signals provided by switches. The spacing between a movable platen holding the movable half mold and a fixed platen holding the fixed half mold is adjusted by adjusting the position of the link housing so that the tie bars are stretched by the extra elongation for a desired mold clamping force when the movable and the fixed half mold are clamped.
