DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method in which one molding condition is composed of a set of a plurality of condition setting data, and the condition setting data is a set value such as an injection first stage speed, an injection first stage position, a heater temperature, and the like. A molding condition management method and a management device for an injection molding machine, comprising a name and set values corresponding to these set value names, wherein a plurality of molding conditions configured as described above are stored and stored in a control device. It is about.

2. Description of the Related Art Injection molding machines are well known in the art, not to mention the name of the document, and are provided with a mold, a mold clamping device, an injection cylinder, and can be driven in the rotation direction and the axial direction in the injection cylinder. It is composed of a screw, a motor for driving the screw, and the like, and also has a control device. A plurality of molding conditions are stored in an internal memory or an external storage device of the control device. As is well known, the molding conditions are composed of an aggregate of a plurality of condition setting data. The condition setting data includes, for example, set value names such as a mold temperature, an injection pressure, an injection time, an injection speed, and the like. It consists of a set value corresponding to the name. Therefore, when one type of molding condition is selected from the stored plural types of molding conditions and the injection molding machine is started, the heater is heated to the set temperature, the screw is rotated at the set rotational speed, and the resin material is measured. Is done.
Then, injection is performed at a set pressure and a set speed. The mold can be opened and the molded product can be taken out.

Since it is also provided with an output terminal for a printer, it can be printed out and confirmed as necessary, and the molding conditions can be edited by changing the condition setting data. There are, however, points to be improved. For example, if a comment is not entered or a mistake is entered even if the control number is assigned, the meaning of the condition setting data or the molding condition may not be understood. Then,
In order to judge what the condition setting data is, the stored data must be displayed or printed out, and all of the condition setting data must be manually compared one by one. Will not be. Further, since the memory for displaying the molding conditions and for printing out is not provided in the control device of the conventional injection molding machine, the molding conditions stored in the first memory are checked or edited. There is also a drawback that the operation of the injection molding machine must be temporarily stopped when displaying the information.

In the plurality of molding conditions stored in the first memory 1, the molding condition of the target No. 2 is different from the other molding conditions, for example, the molding condition of the reference No. 1 in which condition setting data. Confirmation is carried out as follows. That is, the No. 1 molding condition serving as a reference stored in the first memory 1 is called into the first storage device 10. Similarly, the molding condition of the control number of No.
Is stored in the storage unit 11. Then, the individual condition setting data, which are the components of the molding conditions No. 1 and No. 2, are compared with the comparator 1
2 (Step S1 in FIG. 2). As a result of the comparison, if the condition setting data does not match, as shown in FIG. 2, a variable name is determined from the memory address in step S2. In the next step S3, the set value name and the set value data are derived from the variable names and stored in the storage device 13. Then, it is displayed on the display 21 (step S4). FIG. 3 shows an example in which the result of the comparison is displayed on the display 21. FIG. 3 shows management numbers No1 and No2 (condition codes JEL2,

If it is determined in step S1 that the molding conditions of the same address of the management numbers No. 1 and No. 2 match, the process proceeds to step S5. At this time, the fact that the molding conditions match can also be displayed on the display 21 (step S'4). In step S5, it is determined whether the comparison of the memory addresses to be confirmed has been completed. If the molding condition remains to be checked, the memory address counter is advanced by one (step S6), and the next data is compared as described above. Hereinafter, the comparison is similarly performed, and the confirmation is completed.

As described above, as a result of the comparison and confirmation, when there is an error in the condition setting data and it is necessary to correct it, or when it becomes necessary to change the condition setting data and create a new molding condition , And is modified and created by the molding condition editing unit C. For example, when correcting some condition setting data of No. 5 molding condition stored in the first memory 1, the No. 5 molding condition is called into the molding condition working memory 20, and the condition setting data is displayed on the display 21. The displayed condition is displayed and the erroneous condition setting data is corrected by the editor 22 while viewing the data. Then, the molding condition of No. 5 is overwritten. As a result, correction is performed, and when a new management number is added and written, another new molding condition is stored.
