35.5.2 A Mold Temperature Controller
The behavior of a mold temperature controller is modeled as an activity flow shown
in Fig. 35.10. When receiving the request for starting the temperature control from
a injection molding machine, the controlling of the mold temperature for keeping
the constant mold temperature is started. Constancy of mold temperature is kept by
repeating heating and cooling/not heating. When receiving the request for stopping
temperature control from an injection molding machine, the temperature controlling
ends.
In the template for a mold temperature controller, the abovementioned activity
flows are described. The following parameters are described in the property part of
the template.
• controller ID
• action time (start-up, heating, etc.)
• heating capacity
• electric energy consumption (start-up, idling, heating)
• calculation formula for energy consumption (heat retention)
• calculation formula for cumulative energy consumption, etc.
35.5.3 A Molding Extraction Robot
The behavior of a molding extraction robot is modeled as an activity flow as shown
in Fig. 35.11. When receiving the request for extraction of a molded part from an
injection molding machine, the extraction process is started. To extract the molded
part, a robot moves to the gripping position, grips the molded part, moves back to
