Compression molding method and mold clamping apparatus |
摘要 |
Disclosed is a compression molding method comprising the steps of: calculating an average value of mold clamping forces sensed in a plurality of mold clamping mechanisms for clamping a stationary and a movable mold half; obtaining a first control signal on the basis of deviation between a preset target mold clamping force and an average value of sensed mold clamping forces; sensing positions of movable members of the mold clamping mechanisms; obtaining an average value of sensed positions; setting the average value as a successive target position; obtaining a second control signal on the basis of deviation between each of the sensed positions and the successive target position; and obtaining a clamping control signal for each of the clamping mechanisms by adding the first control signal and the second control signal. An apparatus suitable for implementing the method is also disclosed.
