By operating the section, the injection molding machine main body 11 is operated, and continuous molding is started. In this case, the second CPU 37 operates the injection molding machine main body 11 according to the molding conditions stored in the second memory 38 to perform continuous molding.

Usually, after stable continuous molding is started by the injection molding machine main body 11, the mold apparatus 13
There is no need to change the molding conditions, except when replacing the mold. Further, it is not necessary to display the set molding conditions on the display unit 26 and confirm it. Then, after the stable continuous molding is started by the injection molding machine main body 11, the operator removes the cable 30 from the control device 21 and the control device 21 and the personal computer 23.
To shut off between. In this case, the second CPU 37 includes injection molding means (not shown), and the injection molding means operates the injection molding machine main body 11 independently even when the cable 30 is detached from the control device 21 to continue continuous molding. . After the cable 30 is removed, the personal computer 23 and the cable 30 are attached to the control device of another injection molding machine main body, and the molding conditions of the other injection molding machine main body can be set in the same manner as described above.

As described above, since the control device 21 and the personal computer 23 are detachably connected by the cable 30, it is not necessary to arrange the personal computer 23 for each injection molding machine main body 11, and the injection molding machine unit is not required. Cost can be reduced. After the continuous molding is started, when the cable 30 is detached from the control device 21 and the personal computer 23 and the control device 21 are shut off, the second CPU 37
Since the injection molding machine main body 11 can be operated alone and continuous molding can be continued, the operator does not mistakenly operate the operation unit 25 during continuous molding. Therefore, it is possible to normally operate the injection molding machine unit, and it is possible to prevent the occurrence of a defect in the molded product and the breakage of the mold device and the like.

In this embodiment, the serial cable 30 is used as an interface, but a parallel interface may be used.
