Abstract

PURPOSE: To carefully control die clamping force by measuring the die clamping force, comparing with the preset value, calculating the average value in the prescribed times at the time of exceeding the permissible range and correcting the deviation quantity to correct the die clamping force.
CONSTITUTION: The die clamping is executed with the block 4 and extension of a tie bar is detected with the block 5 and operation is executed with the block 6 to obtain the die clamping force. This is compared with the preset value with the block 8 and in the case of being in the permissible range, casting is executed. In the case of being out of the permissible range, it is judged whether the die clamping force data are the prescribed times or not, with the block 11. Generally, three - four times are good. The average value and the deviation value are obtd. with the blocks 12, 13 are after casting, adjustment of the preset value is executed with the block 16. As the judgement of die clamping force correction is executed at each casting, always this can be kept to in the permissible range and quality control of the casting is sufficiently executed.
