1. An injection molding machine, comprising:
a mold clamping device, comprising a movable platen;
an injection device, comprising an injection cylinder; a control device; and
a storage part, comprising a memory, configured to store an inspection program indicating an operation of the injection molding machine;
wherein the control device comprises a processor configured to function as:
a control part which executes the inspection program;
a detection part which acquires, as a reference data, a state of the injection molding machine when the injection molding machine is driven according to the inspection program at a time of shipment, periodic inspection, or replacement of consumables, and the detection part acquires, as a detection data, the state of the injection molding machine when the injection molding machine is driven according to the inspection program at another time different from the time; and
a determination part which identifies a deteriorated spot of the injection molding machine based on the detection data and the reference data,
wherein the detection part acquires:
at least two types or more of the reference data using the inspection program, including:
a first reference data; and
a second reference data;
at least two types or more of the detection data using the inspection program, including:
a first detection data; and
a second detection data;
wherein the inspection program that is used for acquiring the first detection data, the second reference data, and the second detection data is a same inspection program that is used for acquiring the first reference data,
wherein the first reference data and the first detection data are a same type, and the second reference data and the second detection data are a same type,
wherein the determination part is configured to perform a defective spot identification process by performing a plurality of comparisons including a first comparison and a second comparison, the first comparison compares the first detection data with the first reference data, and the second comparison compares the second detection data with the second reference data,
wherein the determination part is configured to identify the deteriorated spot based on a comparison result of the first comparison,
wherein the determination part is further configured to identify the deteriorated spot based on comparison results of both the first comparison and the second comparison jointly, wherein the defective spot identification process performs the second comparison only when a result of the first comparison is a predetermined result.
