BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a display mounting structure of an injection molding machine.

[0002]

2. Description of the Related Art In general, as a method of installing a display of an injection molding machine, a fixed type integrally incorporated in a main body of the injection molding machine has been mainly used. The need to be able to view the display from any direction has come to be required because the devices must be managed simultaneously.

Therefore, a display device (B ') as shown in Japanese Patent Application Laid-Open No. 4-128023 has been proposed. That is,
In the publication, a vertical tightening unit (D ') and an injection unit (I') are arranged in the horizontal direction, and a turning axis (O ') of the unit (I') is provided on the back side of the injection unit (I '). At a more forward position, a pole (9d ') is erected from the base (F'), and the base of the horizontally rotating arm (9 ') is rotatably supported on the top of the pole (9d'). The display (13 ') is mounted on the distal end of the arm (9'), and the display (13 ') is placed at the rear of the injection unit (I') from above the injection unit (I ').
There is proposed a structure in which the arm (9 ') is bent so that the arm (9') can be disposed in front of (I ') and protruded from the front edge of the unit (I').

According to this, as described above, when one operator simultaneously manages a plurality of devices, a display (1) is used.
Adjust the angle of 3 ') to display from any direction
(13 ') can be seen, but the following problems have not been solved. That is, in the injection molding operation using the injection molding machine,
Simply monitoring the display is not all the task of the operator, but maintenance and inspection are also important tasks. One of the maintenance and inspection work includes cleaning of a heating cylinder and a screw. In cleaning the heating cylinder and screw, as shown in FIG. 8, 'to pivot to the front side, the mold clamping unit (D injection unit (I)' it is necessary to remove the injection unit (I ') from) . At this time, the display (13 ') is attached to the tip of the arm (9') that is pivotally attached to the pivot (0 ') mounted on the gantry (F') of the injection molding machine, There is a problem that the display (13 ') must be moved before turning the injection unit (I').

When the display (13 ') is moved, the display (13') is re-displayed at the end of the maintenance and inspection work.
Although (13 ') must be returned to the original position, there is a problem that the adjustment work for returning to the original position becomes complicated because there is no reference position. Further, since the arm (9 ') is installed on the side of the operation side of the injection molding machine, there is a drawback that the maintenance work is hindered.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the problems of the prior art described above, and the problem to be solved is that not only can the display be installed so as to face the most appropriate direction for management, When performing maintenance, the display device also rotates together with the injection unit when the entire injection unit is rotated, and the display device is moved in advance, or readjustment is performed to return the display device to its original position after maintenance is completed. There is no need to.
