摘要： An injection molding machine includes: a cylinder that holds a molding material to be injected into a mold; a plasticizing member provided in the cylinder so as to be movable and rotatable; a temperature measurer that measures a temperature of the cylinder or of the mold; and a period setting unit configured to set a cold start prevention period, which is a period for restricting the injection of the molding material into the mold, based on the temperature measured by the temperature measurer until a temperature of the molding material or the temperature of the mold rises. The period setting unit stores temperature-time data in which the temperature measured by the temperature measurer is associated with time, and adjusts the cold start prevention period based on an actual temperature of the stored temperature-time data.
