Abstract: A mold-clamping force is detected based on an output from a strain detection apparatus (30) provided to a mold-clamping apparatus of a molding machine. A first output value output from the strain detection apparatus (30) is detected when the mold-clamping apparatus is in a maximum mold open state. A second output value output from the strain detection apparatus (30) is corrected based on the first output value when a mold-clamping force is generated by the mold-clamping apparatus. The mold-clamping force is acquired based on the corrected second output value. A correction is made after converting an output from the strain detection apparatus (30) into a digital value, or a strain gauge (50) is used so as to change a reference voltage supplied to a comparison amplifier of the strain gauge using the strain gauge based on the first output value.

Abstract: An adaptor plate is provided between a platen and a mold to measure a temperature of each of divided regions obtained by dividing the adaptor plate into a plurality of regions and adjust a temperature for each of the regions. By doing so, it is possible to adjust the temperature at points closer to the center of the mold than tie bars. Further, by adjusting the temperature of the adaptor plate provided between the platen and the mold, it is possible to precisely adjust a tie bar balance and a platen parallelism even during molding.
