Of the above-mentioned conventional techniques,
The one with the display screen set higher than the injection unit is more convenient in that it monitors the molding machine than the one installed on the side or above the machine base, but the display device can be moved horizontally by the arm. The height of the display screen cannot be adjusted and the angle of the display screen is always kept vertical in the injection molding machine attached to the machine. When changing or adjusting molding conditions by operating the side control panel, the operator's line of sight with respect to the display screen is facing upward and the display screen is viewed diagonally. Depending on the arrangement of the illumination, the illumination light is reflected or the illumination lamp is reflected on the glass of the display screen so that the display cannot be confirmed, and it is often impossible to operate the control panel while observing the display.

[0007] In this way, the problem is also solved.
The problem is solved by making it possible to change the orientation of the display device up and down like the display device described in Japanese Patent Publication No. JP-A-2003-96200. Since the orientation of the display is changed up and down by attaching the support leg and bending it in the middle, this is adopted as a pillar that supports the arm of the above conventional technology, and the orientation of the display is changed in the same way. It is difficult to do so, and it is not easy to fix the upper column that receives the load of the indicator by bending it to the required angle, unless the indicator is too light. It costs.

The present invention has solved the above-mentioned conventional problems, and the object thereof is to change the orientation of the display screen up, down, left and right by moving the display provided on the support member by the operating rod. It is to provide a new injection molding machine.

[0009]

The feature of the present invention according to the above object is to provide a rotating device which can be vertically and horizontally moved by an operating rod and fixed by rotating the operating rod on the top of a supporting member having a required height. The display of the control device is placed and fixed on the seat plate integrally formed on the upper part of the rotating device with the display screen on the side of the operating rod, and the display is mounted on the machine base by the support member. It is to prepare for the work side together with the operating rod.
