DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for editing and storing molding condition storage data in an injection molding machine, and more particularly to an internal storage of a microcomputer (hereinafter referred to as a microcomputer) for controlling the entire machine (injection molding machine). The present invention relates to a method of editing and managing each molding condition data corresponding to a large number of dies stored in a means or an external storage means.

[0002]

2. Description of the Related Art Recent microcomputer-controlled injection molding machines use a microcomputer to control the entire molding process such as charging operation, injection operation, mold opening / closing operation, and ejecting operation. The processing is performed based on molding condition data (molding operation condition setting data) set and stored for each die. The above-mentioned molding condition data is diversified for performing precision molding, and differs for each die (molded product). Therefore, once the data is deleted, it takes a lot of time and trouble to reset it. For this reason, in some injection molding machines, the molding condition data currently stored in the mold molding condition storage area as the current molding operation condition is stored in the microcomputer according to the data storage request of the operator. In the internal storage means (for example, RAM) for saving a file, the data can be stored as a data file for each mold. Further, when the internal storage means is full, the machine transfers the molding condition data currently stored in the mold molding condition storage area as the current molding operation condition to an external storage medium (for example, a RAM board cassette), or One of the data files stored in the internal storage means can be stored in the internal storage means by rewriting (rewriting).

[0003]

In the above-mentioned conventional injection molding machine, the molding condition data (data file for each mold) for each mold stored in the internal storage means in the microcomputer is edited. Little care has been taken with regard to data processing, and editing operations such as deletion of unnecessary data files in the internal storage means and sorting of each data file cannot be performed, so that data files cannot be organized or classified, which is extremely inconvenient. There was a problem. Also, in transferring data to the external storage medium, the molding condition data (data file for each mold) must be read one by one into the current mold molding condition storage area in the microcomputer, and the data file must be transferred one by one. Therefore, transfer of a large number of data files requires a lot of time and labor.

[0004] The present invention has been made in view of the above points,
The purpose is to efficiently transfer data to and from an external storage medium, and to organize and classify data files of molding conditions for each mold (or, in some cases, the same mold but also for each raw material). An object of the present invention is to provide an editing management method of molding condition storage data in an injection molding machine that can be easily divided and is generally easy to use.

[0005]

According to the present invention, in order to achieve the above-mentioned object, each molding condition data corresponding to a large number of dies is stored in an internal storage means of a microcomputer which controls the overall control of the injection molding machine. In a method of editing and managing molding condition storage data of an injection molding machine equipped with a display device capable of displaying various display mode images that can be displayed by an operator's selection, By an appropriate instruction input by an operator in a state where an image for editing and managing molding conditions is called on a display screen of the display device, between the internal storage means and an external storage medium selectively connected to the microcomputer, The molding condition data for each mold can be transferred to each other collectively or partially, and the molding conditions for each mold in the internal storage means or the external storage means can be set.

[0006]

When the operator calls an image for editing and managing molding conditions at an arbitrary time, for example, the molding condition data (data file for each mold) of each molding condition stored in the internal storage means in the microcomputer. The number, model name, date, comment, etc. are displayed in the form of a list. When a desired editing operation is selected by, for example, a function key in this state, an editing operation image corresponding to the selected editing item is displayed on the display image in a window. Then, by selecting a desired data file item on this window image and pushing, for example, an execution key or the like, the selected data file item is copied, moved, deleted, restored (error deletion rescue processing), The change (sort) is executed, and the execution result is displayed in the form of a list. By doing so, the data files of the molding conditions for each mold in the internal storage means or the external storage means can be arranged and classified for any data file from one data file to all data files. In addition, the data file can be copied and moved to and from an external storage medium at a time, and a backup file can be easily and quickly constructed.
