1. An injection molding machine management system comprising:
an injection molding machine including an injection section, a molding section, and a molding processor, the molding processor being programed to:
control the injection section and the molding section to perform an injection molding operation to form a first molded article;
obtain molding data that is gathered while the first molded article is molded in the injection molding operation; and
generate a common identifier relating to the first molded article while the injection molding operation for the first molded article is performed;
a peripheral device receiving the first molded article from the injection molding machine, the peripheral device including a peripheral processor, the peripheral processor being programed to:
receive the common identifier and the molding data for the first molded article from the injection molding machine;
perform a peripheral operation to process the first molded article; and
obtain peripheral data that is gathered while the first molded article is processed in the peripheral operation; and
a control device communicably connected to the injection molding machine and the peripheral device via a network to control the injection molding machine and the peripheral device, the control device including a control processor, the control processor being programed to:
receive the common identifier and the molding data from the injection molding machine and save the common identifier and the molding data in a memory in correlation with each other;
receive the common identifier and the peripheral data from the peripheral device and save the common identifier and the peripheral data in the memory in correlation with each other; and
specify a cause of a failure of the first molded article based on the common identifier, the molding data, and the peripheral data when the failure of the first molded article occurs,
wherein the common identifier includes information corresponding to a shot number for molding the first molded article in the injection molding machine.
