PROBLEM TO BE SOLVED: To provide a pressure measurement device of an injection molding machine, which has a simple structure, is inexpensive, does not require time and labor for measurement, dispenses with a set-up of a mold and work of removing a molding material, and can suppress variations of measurement in continuous operations, and a pressure measurement method of the injection molding machine and an adjustment method of the injection molding machine.SOLUTION: A pressure measurement device 50 comprises: a reception member 51 having a reception face 51a which faces a tip end face 45b of an injection unit 40 on which an injection port 45c is provided, and receives the tip end faces 45b; and a detection part 55 which is held by the reception member 51, and detects pressure received from the molding material. The reception face 51a has curvature equal to or larger than that of the tip end face 45b. The detection part 55 has a detection reception face 55a for receiving pressure from the molding material in a state that the detection reception face is disposed on the same axis of the injection port 45c, and the detection reception face faces the injection port 45c and is disposed in the vicinity of the injection port, when the tip end face 45b comes in contact with the reception face 51a.SELECTED DRAWING: Figure 2A |
