Abstract
A temperature monitoring device for an injection unit of an injection molding machine is provided with a heater to heat a nozzle and a heating cylinder, a temperature sensor to detect a current temperature of the nozzle and the heating cylinder or around the heating cylinder, and an electromagnetic locking device to prohibit a safety door from opening when the current temperature detected by the temperature sensor exceeds a predetermined opening operation prohibited temperature.
Claims6
A temperature monitoring device for an injection molding machine with a heating cylinder covered by an openable shield, the temperature monitoring device comprising:
- a heating unit configured to heat the heating cylinder;
- a detecting unit configured to detect a current temperature of or around the heating cylinder;
- a storage unit configured to store a prohibited temperature at which the shield is prohibited from opening;
- and
- a prohibition unit configured to prohibit the shield covering the heating cylinder from opening if the detected current temperature exceeds the prohibited temperature.
