Abstract
Variables such as injection pressure and injection velocity are detected at a predetermined sampling cycle for each molding cycle and the variables for a plurality of past molding cycles starting from the latest molding cycle are stored. Change patterns of the stored variables of the respective molding cycles are displayed in the form of graphs in which the first axis represents time (the number of times of sampling), the second axis represents the variable values, and the third axis represents the molding cycle.
Claims7
A monitor for an injection molding machine, comprising:
- sampling means for detecting, in each of successive molding cycles a molding cycle variable, varying in each molding cycle in an injection molding process, and storing the detected variable;
- means for storing an end of cycle time for each molding cycle;
- and
- means for graphically displaying the detected variables for a plurality of molding cycles, with a first axis representing time, a second axis representing said detected variables and a third axis representing said molding cycles.
