1. An injection molding machine management system comprising:
an injection molding machine configured to inject a plasticized material into a mold to form a molded product;
a take-out robot configured to take the molded product from the injection molding machine and remove a sprue and a runner from the molded product;
an inspection device configured to receive the molded product from the take-out device and inspect the molded product with respect to measuring a dimension and a weight of the molded product to determine whether a type of defect of the molded product occurs;
a memory configured to store a program and a predetermined maintenance period of time for the mold; and
a processor configured to execute the program to control the injection molding machine management system by communicating with the injection molding machine, the take-out device, and the inspection device so as to:
receive, from the injection molding machine, physical information including identification information of the mold and the injection molding machine, a shot number of injection molding with respect to the mold, an injection filling time with respect to the mold, an injection pressure, a mold clamping force, and a set temperature of each part of the injection molding machine;
receive, from the inspection device, an inspection result including the measured dimension and weight and the type of defect of the molded product;
display the received physical information and the inspection result on a display as a time-series graph format for a period of time corresponding to two or more maintenance periods, wherein the display is divided into a plurality of display areas including:
a top display area in which the shot number of injection molding with respect to the mold is displayed;
an intermediate display area in which the dimension and the weight of the molded product, a cushion amount, and a cavity temperature are displayed; and
a bottom display area in which maintenance information and the identification information of the injection molding machine and an environmental humidity are displayed; and
notify an operator of a necessity of maintenance based on:
the predetermined maintenance period of time;
the received physical information; and/or
the inspection result.
