ABSTRACT:
A method for controlling injection molding using a neural network in a control device of an injection molding machine. A measurement monitor value is acquired in a measurement step during test injection molding and an injection monitor value is acquired in an injection step. The acquired measurement monitor value is designated as an input term and the injection monitor value is designated as an output term. A prediction function that incorporates the measurement monitor value is then determined using the neural network. A first value corresponding to the injection monitor value is predicted by substituting into the prediction function a measurement monitor value acquired at completion of a measurement step during mass-production injection molding. On the basis of the predicted first value, a second value corresponding to an injection condition is determined. Injection control and pressure maintenance control are then implemented on the basis of the second value corresponding to the injection condition.
