PROBLEM TO BE SOLVED: To provide a load sensing device of an injection molding machine which can correct temperature drift of a sensor used in a place added regular load with a simple method without arranging a temperature sensor separately.SOLUTION: On the basis of a detection value acquired in a state that load added to a first sensor is almost no load in a molding cycle, a detection value of a second sensor is corrected by estimating ambient temperature of an injection molding machine. The detection value of the second sensor can be corrected appropriately by acquiring the detection value in a state that the first sensor is no load, without arranging a temperature sensor separately, even in the absence of state of no load to the second sensor.SELECTED DRAWING: Figure 1 |
