Description

  The present invention relates to a display device that displays a list of molding conditions stored in a storage device of an injection molding machine.

  In order to mold a molded product with an injection molding machine, it is necessary to set respective operating conditions for each process of mold closing, injection, holding pressure, weighing, mold opening, and protrusion of the molding operation. These operating conditions are collectively referred to as molding conditions.

  In order to mold a good product by injection molding, it is necessary to adjust the molding conditions for each of the above steps. This adjustment work needs to be repeated until a good product is formed, which is a difficult work requiring a long time. For this reason, the molding conditions when a good molded product is obtained are stored in a storage means installed inside or outside the injection molding machine corresponding to the mold or molded product to be used, and then again When molding the same molded product as the previous one using the same mold, the molding conditions are read from the storage means corresponding to the mold or molded product, and the read molding conditions are automatically batched into the injection molding machine. Are known (see Patent Documents 1 to 3).

  Also, a method is generally used in which identification information such as a name and ID number is added to the molding conditions when storing in the storage means, and when the molding conditions are read from the storage means, a list of identification information is displayed and the target molding conditions are selected from the list. (See FIG. 11).

  Once the adjustment operation is completed, the same molding conditions are generally used as long as the same mold or molded product is continuously produced. However, the molding conditions once adjusted are further adjusted to create new molding conditions due to changes in the environment such as the ambient temperature and humidity of the molding factory and changes in the characteristics of the resin used. In this manner, a plurality of similar molding conditions are created and stored using the molding conditions for which adjustment has been completed first as a basic condition.

  As described above, a plurality of similar molding conditions are stored in the storage unit of the injection molding machine. As a method of selecting desired molding conditions corresponding to various conditions such as mold, environment, and resin from multiple molding conditions, the stored molding conditions are read and displayed on the screen of the injection molding machine. Methods for doing this are known. In the conventional method, since the memorized molding conditions can be confirmed before being applied to actual molding, it is possible to search for desired molding conditions to be applied to the next molding even during the molding operation. However, this method has been inefficient since the stored molding conditions must be read and the contents of the displayed molding conditions checked repeatedly until the desired molding conditions are found.

  Therefore, in Patent Document 4 and Patent Document 5, image data and memo data are stored together with molding conditions to solve this problem, and when the molding conditions are read, the image data and memo data are displayed at the same time. Solved the problem. However, in the case of this known technique, there is a problem that the labor for storing the image data and the memo data together with the molding conditions increases, and the burden on the operator is large in actual operation. Alternatively, in Patent Document 3, in order to find a desired molding condition, when displaying the file name of the molding condition file stored in the file for each molding condition, a recently used molding condition file, a frequently used molding condition file, The problem was solved by changing the display mode of the molding condition file selected by the user. However, the desired molding condition file is not always in the molding condition file in which the display mode is changed.

  Accordingly, an object of the present invention is to provide a display device and a display method for an injection molding machine that can easily find a desired molding condition from similar molding conditions without increasing the burden on the operator. .

The invention according to claim 1 of the present application is a storage means for storing a plurality of molding conditions consisting of a plurality of molding condition items and identification information for specifying the molding conditions, and at least one molding condition among the molding condition items. Selection means for selecting an item; designation means for designating a comparison condition for the value of the molding condition item selected by the selection means; and reading the value of the selected molding condition item from the plurality of stored molding conditions Determining means for determining whether the read value matches the designated comparison condition; and molding conditions determined by the determining means that the read value matches the designated comparison condition; Means for displaying a list of identification information of the molding conditions so that the display form of the molding conditions determined that the read value does not match the specified comparison condition is different. A display device for an injection molding machine.

The invention according to claim 2, and identification information for identifying the molding conditions and molding conditions consisting of a plurality of molding condition items store a plurality, selecting at least one of the molding condition items of the molding condition items, A comparison condition is designated for the value of the selected molding condition item, the value of the selected molding condition item is read from the plurality of stored molding conditions, and the read value matches the designated comparison condition. or to determine, as the display mode of the molding conditions is judged not to meet the comparison condition value the read value read said discriminated as molding conditions and meet the comparison condition mentioned above specified has the specified different This is a display method of an injection molding machine that displays a list of identification information of molding conditions.
