FIG. 3 is a diagram for explaining an outline of processing in the injection molding machine 1A and the injection molding machine 1B according to this embodiment.
In the injection molding machine 1A shown in FIG. 3, as shown in (1), a speed (100 mm/s in this case) which is a molding condition is set using a setting screen displayed on the display unit 28. The mechanical capacity value of the injection molding machine 1A stored in the capacity value storage unit 22 is, for example, the maximum acceleration of the control axis is 1 m/s ² .
As shown in (2), the control unit 10 (command value generation unit 11) of the injection molding machine 1A controls the control command value based on the molding condition set on the setting screen and the mechanical capacity value of the injection molding machine 1A. To generate. Then, the control unit 10 (operation control unit 12) of the injection molding machine 1A controls the movable portion based on the generated control command value, as shown in (3).

The graph shown in (A) in the figure is the velocity waveform of the control command value generated in (2).
Then, when it is desired to produce the same molded product as the molded product in the injection molding machine 1A in another injection molding machine 1B, the control unit 10 of the injection molding machine 1A sets the molding condition as shown in (4). Generate a file. The molding condition file includes the set molding conditions and the mechanical capacity value of the injection molding machine 1A.

Next, the processing in the injection molding machine 1B in which the mold is transferred from the injection molding machine 1A will be described.
The control unit 10 (file receiving unit 13) of the injection molding machine 1B receives the molding condition file generated by the injection molding machine 1A, as shown in (5).
The injection molding machine 1B outputs the molding conditions included in the received molding condition file to the setting screen displayed on the display unit 28, as shown in (6). Further, the mechanical capacity value of the injection molding machine 1B stored in the capacity value storage unit 22 is, for example, the maximum acceleration of the control axis is 2 m/s ² .
As described above, the mechanical capacity value of the injection molding machine 1B is different from the mechanical capacity value of the injection molding machine 1A, and the injection molding machine 1B has a higher mechanical capacity value than the injection molding machine 1A.

Therefore, the control unit 10 (command value generation unit 11) of the injection molding machine 1B, based on the molding condition output on the setting screen and the mechanical capacity value of the injection molding machine 1B, as shown in (7). , Generate a control command value. As described above, the mechanical capacity value of the injection molding machine 1B is higher than the mechanical capacity value of the injection molding machine 1A. Therefore, as in the graph shown in (B) in the figure, the velocity waveform of the control command value generated in (7) is different from the graph shown in (A) in the figure (the latter is the case of the initial movement). Has a large acceleration). Therefore, even if the molding conditions are the same, under this condition, the injection molding machine 1B cannot produce the same molded product as the injection molding machine 1A.

Therefore, as shown in (8), the control unit 10 (command value correction unit 15) of the injection molding machine 1B, the mechanical capacity value of the injection molding machine 1B, and the mechanical capacity of the injection molding machine 1A included in the molding condition file. The generated control command value is corrected based on the value and. Specifically, the acceleration is corrected to be small.
Then, the control unit 10 (operation control unit 12) of the injection molding machine 1B controls the movable unit based on the corrected control command value, as shown in (9).
The graph indicated by (C) in the figure is the velocity waveform of the corrected control command value corrected in (8). The velocity waveform shown in (C) has the same shape as the velocity waveform shown in (A). Therefore, also in the injection molding machine 1B, the operation amount of injection molding can be automatically corrected so that the same molded product as the injection molding machine 1A can be obtained.

Next, the above-mentioned processing will be described based on a flowchart.
First, the control processing in the injection molding machine 1A will be described based on FIG.
FIG. 4 is a flowchart showing the control processing of the injection molding machine 1A according to this embodiment.
In step S (hereinafter, “step S” is simply referred to as “S”) 11 in FIG. 4, the control unit 10 sets molding conditions using the setting screen. In the above example, the speed was explained as the molding condition, but the molding condition is not limited to this. Other items may be used as long as they are molding conditions. Further, the molding condition is not limited to one.

In S12, the control unit 10 determines whether or not molding conditions have been set. For example, the control unit 10 may determine that the molding condition is set when the molding condition is input through the input unit 27 and the operation of confirming the molding condition is performed. When the molding condition is set (S12: YES), the control unit 10 moves the process to S13. On the other hand, when the molding condition is not set (S12: NO), the control unit 10 shifts the processing to S11 and waits for the molding condition to be set.

In S13, the control unit 10 (command value generation unit 11) generates a control command value for the movable section based on the set molding conditions and mechanical capacity value.
In S14, the control unit 10 (operation control unit 12) controls the movable unit based on the generated control command value.

In S15, the control unit 10 determines whether or not the injection molding machine 1B performs a process for producing the same molded product as that of the injection molding machine 1A, that is, the control unit 10 stores the molding condition file. Determine whether to generate. The control unit 10 can make this determination, for example, according to an operation by the operator for generating a molding condition file. When the molding condition file is generated (S15: YES), the control unit 10 shifts the processing to S16. On the other hand, when the molding condition file is not generated (S15: NO), the control unit 10 ends this process.
In S16, the control unit 10 performs a file generation process. After that, the control unit 10 ends this processing.

Next, the file generation process will be described with reference to FIG.
FIG. 5 is a flowchart showing a file generation process of the injection molding machine 1A according to this embodiment.
In S21 of FIG. 5, the control unit 10 generates a molding condition file that includes the molding conditions stored in the storage unit 20 and the mechanical capacity values stored in the capacity value storage unit 22.
In S22, the control unit 10 stores the generated molding condition file in the storage unit 20.

In S23, the control unit 10 determines whether or not to send the molding condition file to the injection molding machine 1B. The control unit 10 can make this determination according to, for example, an operation by the operator for transmitting the molding condition file. When transmitting the molding condition file (S23: YES), the control unit 10 shifts the processing to S24. On the other hand, when the molding condition file is not transmitted (S23: NO), the control unit 10 ends this processing. Since the molding condition file is stored in the storage unit 20, it can be transmitted to the injection molding machine 1B at an arbitrary timing, for example, according to an instruction from the operator.
In S24, the control unit 10 transmits the molding condition file to the injection molding machine 1B via the communication unit 29. After that, the control unit 10 ends this processing.

Next, the correction control process in the injection molding machine 1B will be described with reference to FIG.
FIG. 6 is a flowchart showing a correction control process of the injection molding machine 1B according to this embodiment.
In S31 of FIG. 6, the control unit 10 (file receiving unit 13) of the injection molding machine 1B receives the molding condition file from the injection molding machine 1A via the communication unit 29.
In S32, the control unit 10 (molding condition setting unit 14) reads the received molding condition file and outputs the molding condition contained in the molding condition file to the setting screen.
In S33, the control unit 10 (command value generation unit 11) moves based on the molding condition output on the setting screen and the mechanical capacity value of the injection molding machine 1B stored in the capacity value storage unit 22. Generates a control command value for a part.

In S34, the control unit 10 (command value correction unit 15) causes the mechanical capacity value of the injection molding machine 1A included in the received molding condition file and the mechanical capacity of the injection molding machine 1B stored in the capacity value storage unit 22. The generated control command value is corrected based on the value and.
In S35, the control unit 10 (operation control unit 12) controls the movable unit based on the corrected control command value. After that, the control unit 10 ends this processing.

It should be noted that what has been described above is the process for producing the same molded product as the injection molding machine 1A in the injection molding machine 1B. Therefore, when a molded product is produced using the maximum capacity of the injection molding machine 1B, the injection molding machine 1B may perform the control process described in FIG.

As described above, the injection molding machine 1A generates a molding condition file including the molding conditions used in the injection molding machine 1A and the machine capability value. Then, when the mold is transferred to the injection molding machine 1B having a different mechanical capacity value and molding is performed, the maximum capacity of the injection molding machine 1A included in the molding condition file received from the injection molding machine 1A at the injection molding machine 1B. The control command value for controlling the movable part is corrected so that the same molded product can be obtained based on. Therefore, the operation amount of injection molding of the injection molding machine 1B can be automatically corrected.
Since the correction of the control command value is automatically performed based on the mechanical capacity value of the injection molding machine 1A and the injection molding machine 1B, the operator or the like adjusts the molding conditions in consideration of the difference between the injection molding machines 1. There is no need to do it and the burden can be reduced.
