    摘要： An injection molding machine (10) is provided that includes a clamping force sensor (17) that detects a clamping force of a mold (30), and a clamping force monitoring unit (82) that monitors a detected value of the clamping force sensor (17) and calculates a first mold open distance and/or a second mold open distance. The first mold open distance is calculated based on the difference between the maximum value of the detected values obtained during an injection process and a pressure holding process and the detected value obtained at the start of the injection process. The second mold open distance that is calculated based on the difference between the detected value obtained at the end of the pressure holding process and the detected value obtained at the start of the injection process.

    摘要： An injection molding machine that improves the stability of pressure control in a holding pressure process is provided. The injection molding machine includes a cylinder that heats a molding material that fills the inside of a mold unit; an injection member that is disposed within the cylinder so as to be movable forward and backward; a driving source that moves the injection member forward and backward; and a controller that controls the driving source. The controller lowers a control gain used for the control of the driving source during in a holding pressure process when driving the driving source.
