Method, apparatus, and medium for forming molding condition and molding machine

An injection molding condition forming method in an inject molding machine comprising the steps of:

• obtaining a resin pressure curve of a cylinder-side end of a molding machine nozzle portion obtained by a resin flow analysis using a resin flow path in a die and the nozzle portion of the molding machine as objects to be analyzed;
• obtaining an injection pressure curve in an air shot;
• and
• obtaining an injection pressure curve serving as a molding condition based on the injection pressure curve in the air shot and the resin pressure curve obtained by the resin flow analysis.

An injection molding machine comprising:

• means for storing a resin pressure curve at a resin inlet port of a die calculated by a resin flow analysis for analyzing a flow of resin in the die;
• means for obtaining an injection pressure curve in an air shot;
• and
• means for obtaining an injection pressure curve serving as a molding condition based on the injection pressure curve in the air shot and the resin pressure curve obtained by the resin flow analysis.
