A display apparatus for an injection molding machine which permits setting items unalterable during operation of the injection molding machine to be identified on the screen. When the injection molding machine is not in operation, the setting items on the screen are shown in a normal first display appearance. During operation of the machine, unalterable setting items, among the setting items on the screen, are shown in a second display appearance to be distinguished from the first display appearance. Since setting items that are normally alterable but should not be altered during operation of the injection molding machine are displayed in the second display appearance in a distinguishable manner, such setting items can be clearly identified, thus improving operability.

Display apparatus for injection molding machine

A monitoring device and a monitoring method for an injection molding machine, in which a trend chart is displayed on a common axis so that changes of set values of molding conditions and changes of measured values of monitoring items can be grasped correspondingly. A history of the measured values of the monitoring items is stored, and a change history of the set values of the molding conditions is also stored. An operator sets monitoring items and molding condition items to be displayed. In doing this, the operator sets a display range such that molding condition items having changed set values within the display range are displayed and selected. Alternatively, coefficients of correlation between the measured values of the selected monitoring items and the set values of the molding conditions are obtained, and the molding condition items are displayed in the order of priority of correlation and selected. For example, a metering time, minimum cushion amount, and peak pressure are selected as the monitoring items, and a first stage injection speed and barrel 3 temperature as the molding condition items. Thus, the trend chart is displayed with a time base on its abscissa axis, and the influence of the set values on the measured values can be grasped with ease.

Monitoring device and monitoring method for injection molding machine

A molding information printing system, including a network; a molding machine connected to the network; a printer for printing the molding information of the molding machine; a print control section connected to the network independently of the molding machine, for controlling the printer for printing of the molding information; and an instructing section for instructing printing of the molding information and transferring a command to the print control section through the network. The molding machine includes a control unit connected to the network, and the instructing section is provided in the control unit. Also, the system includes a computer connected to the network independently of the molding machine, and the print control section is provided in the computer.

Molding information printing system

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.
