A control device of an injection molding machine which injects a molten resin from an injection nozzle is provided with a display section in which a touch panel is disposed, and a human-machine interface section equipped with a general-purpose operating system, and the human-machine interface section is provided with at least a storage section to store set values which are various molding conditions for each mold article and a control section which controls the display of the display section. The interface section displays, on the display section, a main screen to change settings for the molding conditions stored in the storage section and a subscreen to display indications such as monitors, and also constantly displays a change switch for a change of the screen in a fixed region of the display section.

Control device for use in injection molding machine

A barrel has an injection nozzle at the forward end, and an injection screw inside, and heaters in the outer circumference. The barrel injects the molten resin from the injection nozzle at the forward end by the rotation of the injection screw. In the barrel, the temperatures of each parts are controlled by a temperature control section. A controller sets a shift minus temperature to uniformly lower the temperature of the parts, and a shift absolute temperature to lower the temperatures of the parts to a predetermined temperature. An operation panel section selects the shift minus temperature or shift absolute temperature to lower the temperatures of the parts. The temperature control section lowers the temperatures of the parts of the barrel by using the temperature selected when the injection molding machine is temporarily stopped.

This invention is a numerical control unit including a main controller for carrying out a numerical controlling step and a personal computer connected to the main controller through a bus-line. An operating panel includes a keyboard having keys. A key-encoder is connected to the main controller, the personal computer and the keyboard for assigning the keys of the keyboard as key or keys for the main controller or as a key or keys for the personal computer respectively. The numerical control unit can freely assign the keys of the keyboard in the operating panel as the key or keys for the main controller or as the key or keys for the personal computer respectively. Thus, the operating panel suitable to operate can be achieved effectively and efficiently.
