Patent Searching and Data


Title:
トグル式型締装置の型締力補正方法
Document Type and Number:
Japanese Patent JP4146381
Kind Code:
B2
Abstract:
A closure position detection mode is provided so as to obtain a rate of variation (which encompasses an amount of variation) in a physical quantity to a predetermined amount of movement of a movable platen or a crosshead, and detect, as a mold closure position, a position when the variation rate reaches a preset ratio. The mold clamping apparatus is previously operated in the closure position detection mode so as to store, as a reference value, the mold closure position at which a target mold clamping force is obtained. In production operation, the mold clamping apparatus is operated in the closure position detection mode so as to obtain an actual mold closure position (detection value). The mold clamping force is corrected on the basis of a deviation of the detection value from the reference value.
