Abstract

PURPOSE:To hold surface pressure of metallic-mold split surface uniform and in a set range by detecting the elongation of the part where tensile force is generated at the time of the mold clamping of tie bars arranged between a fixed platen and supporting part for mold-clamping-force generator, and by automatically suppressing the tensile force within a set range corresponding to respective tie bars. CONSTITUTION:As for tie bars 18 provided between fixed platen 14 and supporting part 16 for mold-clamping-force-generator, the elongation of the part where tensile force is generated in mold clamping is detected; when the arithmetic mean of the elongation of tie bars 1 is less than a set center value, the length of the part of tie bar 18 with the tensile force whose elongation is less than a set lower limit among tie bars 18 is shortened by a set correction value, and when the arithmetic mean of the elongation is greater than the set center value, the length of the part of tie bar 18 with tensile force whose elongation is greater than a set upper limit is elongated. Thus, the correction is automatically made by a die height adjusting device until the elongation of respective tie bars is in the set range perfectly.
