It is necessary to set various conditions such as set temperature at each point of the heating cylinder.

In conventional injection molding machines, when setting these 1 molding conditions, these molding conditions are stored on a magnetic card, etc., and the molding conditions stored on the card are read with a card reader and injection molding is performed. The above-mentioned molding conditions were stored in the machine or stored on a floppy disk, and these molding conditions were set from the floppy disk. Therefore, in order to set the molding conditions, an external storage device such as a magnetic card or a 70-bit disk was required, and it took time to set the molding conditions.

Problems to be Solved by the Invention The object of the present invention is to improve the above-mentioned prior art and provide a molding condition setting method that can easily, reliably, and quickly set molding conditions.

Means for solving the problem A setting memory for setting molding conditions is stored in the non-volatile memory in the control device of the injection molding machine, and each data set in the setting memory is stored as a molding condition file for each mold used. The above problem is solved by providing a molding condition file memory to be stored in the molding condition file memory.

Setting molding conditions in the setting memory corresponding to each mold for each molding type, and storing the molding conditions set in the setting memory as a molding condition file in the molding condition file memory for each mold. Then, the product to be molded is decided.
Once a mold is determined, by inputting the code corresponding to the mold, the corresponding molding condition file in the molding condition file memory is transferred to the setting memory, and the injection molding operation is performed according to the molding conditions stored in this setting memory. Let it start.

(operation panel with display) is used to input molding conditions and various commands and display them on a CRT or the like.

As shown in FIG. 2, the nonvolatile memory is provided with a setting memory, Ml, and a molding condition file memory M2.
The setting memory M1 stores various molding conditions 1 to n set from the MDi & CRT8, reads molding condition files 1 to Ill from the molding condition file memory M2, and stores them in this setting memory M1.
The injection molding machine will be controlled by the molding conditions 1 to n stored in . The molding condition file memory M2 is a memory that stores the molding conditions set in the setting memory M1 as a molding condition file, and each of the molding conditions 1 to n, including the mold used to create the molded product and the resin used, are stored respectively. 1 to Il are stored as molding condition files, and the memory capacity of each molding condition file is set according to the maximum number of molding conditions.

Figure 3 is an example of a molding condition file list screen displayed on the MDi & CRT8 screen. In this example, molding condition file numbers 1 to 30 are displayed, and the mold code is assigned to correspond to each number. It is now possible to input. This mold code can be input and displayed as a code so that the mold, resin, etc. used for molding can be identified and recognized. For example, mold code A, B,
C.

Item D indicates that injection molding is performed under the molding conditions of molding condition file 2.

Next, a method for creating the above-mentioned molding condition file will be described.

Display the setting screen for each molding condition on the CRT from the operation panel of MDi & CRT8, set each molding condition, and save the setting memory M.
1, set the molding conditions respectively. Next, display the molding condition file list shown in Figure 3 on the CRT, and enter any one of the molding condition files No. 1 to 30 for each mold code that is distinguished by the mold, resin, etc. used under the set molding conditions. Move the cursor and enter the registration key on the soft key.

Then, the mold code is input and displayed in the molding condition file number set on the molding condition file list screen in FIG. This will be stored as a molding condition file.

In this way, the settings are stored as a molding condition file list for the codes assigned to each mold depending on the difference in the mold or resin used, and the molding conditions are stored as molding condition files 1 to m for each mold code. .

Next, when manufacturing a new molded product, replace the mold, display the molding condition file list shown in Figure 3, search for the mold code that corresponds to the molded product you are trying to manufacture, and move the cursor to set it. After that, when the call key of the soft key is input, the molding condition file of the mold code stored in the molding condition file memory M2 is transferred to the setting memory M1. In this way, the control device 2 uses this setting memory M1.
Injection molding is controlled according to the molding conditions 1 to n stored in . For example, when using molds with mold codes A, 8°C, and D, move the cursor and select NO2, and input the soft key call, and molding condition file 2 will be transferred to setting memory M1 and stored. Then, the CPU 3 performs the injection molding process according to the molding conditions 1 to n stored in the setting memory M1.
