Method and apparatus for controlling molding machine

摘要

There is provided a molding machine controlling unit and method capable of preventing the operation of a molding machine from suddenly stopping due to the temperature of an electric motor. The control unit comprises: a calculating part 40 for analyzing molding condition data to generate a command value for producing a torque to the rotating shafts of electric motors 71 through 73 of an injection molding machine and to calculate an effective value on the basis of the command value; an entry part 30 for entering a reference value, which is to be compared with the effective value, and the molding condition data; a storing part 35 for storing the reference value and the molding condition data; a display part 50 for displaying the effective value and the reference value; and driving parts 61 through 63 for entering the command value to drive the rotating shafts of the electric motors, wherein the effective value and the reference value are displayed as a standard for preparing the molding condition data so that the effective value does not exceed the reference value.
