PROBLEM TO BE SOLVED: To provide an injection molding machine that can manage a temperature of resin in a cylinder.SOLUTION: An injection molding machine 10 includes: a cylinder 41 from which a resin material is supplied; a plurality of heating sources 91-94 to heat the cylinder 41; a plurality of temperature sensors 21-24 that detect temperatures of different positions of the cylinder 41; a control device 80 that controls the plurality of heating sources 91-94 based on the differences of the measured temperatures of the temperature sensors 21-24 with the target temperatures in measurement positions of the temperature sensors 21-24. The target temperature distribution in the cylinder shaft direction of the cylinder inner wall is set beforehand. The control device 80 calculates target temperatures in the measurement positions of the temperature sensors 21-24 based on the target temperature distribution, and controls the plurality of heating sources 91-94 by using the calculated target temperatures. |
