However, the content of locking the safety door according to the current temperature of the heating cylinder is not disclosed
[0009] As mentioned above, in the prior art, since the safety door is opened and closed without considering the current temperature of the heating cylinder or the nozzle, the risk of the worker being burned by touching the heating cylinder cannot be ruled out.

Embodiment Construction

[0026] figure 1 Shows the structure of the injection unit and temperature monitoring unit of the injection molding machine.

[0027] The injection molding machine is equipped with an injection device and a mold clamping device on the machine base. The description of the mold clamping device is omitted. Reference numeral 1 denotes an injection device of an injection molding machine. The injection device 1 includes a heating cylinder 6 on which the nozzle 4 is mounted, a front plate 8 on which the heating cylinder 6 is mounted, an injection motor M1, and a nozzle touching motor M2. The resin material thrown into the hopper 7 is supplied into the heating cylinder 6 . The mold 2 is fixed to the fixed platen 3 having a through hole formed in the center through which the nozzle 4 of the heating cylinder 6 is inserted.

[0028] The base frame 19 is provided with a fixed platen 3 and a movable guide rail 18 for the injection device. The injection device 1 can be moved along the m...

Abstract

The invention provides a temperature monitoring device for an injection molding machine. The temperature monitoring device for an injection unit of the 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.

Description

technical field [0001] The present invention relates to a temperature monitoring device for a heating cylinder of an injection molding machine. Background technique [0002] Generally, the injection device of an injection molding machine includes a heating cylinder that heats and melts the resin for molding and maintains the molten state of the resin, and is additionally provided at the front end of the heating cylinder to inject the resin melted in the heating cylinder into a mold. Nozzles in the cavity. The temperature of the heating cylinder and the nozzle is controlled to a set temperature without deviation by using a temperature measuring mechanism such as a thermocouple and a heating mechanism such as a heater installed additionally on the heating cylinder to maintain the molten state of the resin. In addition, the temperature of the heating cylinder necessary to maintain the molten state of the resin is determined by the resin, and is, for example, 200 to 450°C. By ...
