Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a mounting structure for an operation panel of a control device used when setting molding conditions of an injection molding machine.

[Prior Art] The mounting structure of the control panel described in Japanese Utility Model Laid-Open No. 62-189114 has a structure in which the control panel is housed in a machine base, and the control panel hinged to the upper opening of the housing and the housing. A damper is arranged across the inner wall.

In the operation panel described in Japanese Utility Model Laid-Open No. 63-27308, the operation panel is housed in a recess formed in the side plate of the machine base, and the operation panel has a fan-shaped movable upper part, a bottom part, and a lower part of the recess. A damper is installed over the entire area.

[Problems to be Solved by the Invention] In any of the above conventional structures, a damper is directly connected to a control panel or an operation panel integrated with a control device, and one of the dampers is fixed to a base or frame of a machine base. As a result, it requires a lot of force to pull it out, and even when the control panel and other parts are partially defective, there is the inconvenience that repairs and replacements cannot be done without removing the entire part from the damper.

This invention was conceived in order to solve the above-mentioned conventional problems, and its purpose is to facilitate the installation of the operation panel by utilizing the door and the frame of the control unit provided on the machine side. Another object of the present invention is to provide an operation panel mounting structure having a new configuration that enables repair and replacement of the operation panel without removing the damper.

[Means for Solving the Problems] According to the invention for the above object, a required recess is formed in a door of a control unit provided on a side surface of a machine base, and a withdrawal gap is opened in the recess to form a frame body. It is housed and the upper end of the frame is hinged to the upper part of the recess and hung so that it can move in a fan shape upward, and a damper for holding is provided between the frame and the side of the recess, and the surface of the frame is transparent. A cover plate is hinged so that it can be opened and closed, and an operation panel having a setting panel is attached separately from the control device in a frame body below the cover plate.

If necessary, the frame body and the cover plate can be connected by a holding damper.

[Operation] In the above configuration, when a hand is inserted into the gap below the frame and pulled outward, the frame moves in a fan shape together with the operation panel and the like against the damper. This movement can be carried out to the point where the damper is fully extended and can be held by the damper in the stop position.

Since the operation panel pulled out from the recess is covered with the cover plate, when the condition is set, the operation is performed by opening the cover plate.

[Embodiment] In the drawing, 1 is a machine base of an injection molding machine, which has a control unit 2 inside. Reference numeral 3 denotes a door of the control unit 2 which forms a part of the side surface of the machine base.

A rectangular window hole is formed in the upper part of the surface of the door 3,
A press plate 5 that forms a recess 4 in the window is attached from the inside. A rectangular frame 6 along the periphery of the recess 4 is housed in the recess 4 with a space 7 for pulling out at the lower side. Further, the frame body 6 is fan-shaped movably suspended at the upper end of the recess using a butterfly plate 8, and a holding damper 9 composed of a cylinder 9a and a piston 9b extends over the inside of the frame body and the recess side portion 4a. It is provided.

A control panel 10 is formed separately from the control device 11, and has a setting panel such as a light emitting diode display, a liquid crystal display, a plasma display, an electroluminescence display, and the control device 1 mounted on the back side of the door 3.
It is electrically connected to 1. The operation panel 10 is attached with its periphery fixed to the back side of the frame surface plate 6a. On the front surface side of the frame body 6, a transparent plastic cover plate 12 is attached to the frame body surface plate 6a with a butterfly plate 13 at the opening and closing sides.

In FIG. 4, a damper 14 similar to the damper 9 is attached so as to extend over the frame 6 and the cover plate 12 so that the cover plate 12 can be stopped and fixed at a predetermined opening angle.

Reference numeral 15 is a stopper member.

In the above structure, the hand is inserted into the gap 6 on the lower side of the frame body so that the frame body 6
When is pulled outward, the frame body 6 moves in a fan shape together with the operation panel 10 and the cover plate 12 against the damper 9. This movement can be carried out to the point where the damper 9 is fully extended, and is held by the damper 9 in the stop position.

Since the operation panel 10 pulled out from the recess 4 is covered with the cover plate 12, the cover plate 12 is opened when conditions are set, and setting operations such as control are performed.
When the lower portion of the frame body 6 is pressed, the frame body moves downward against the damper 9 and fits vertically in the recess 4.

[Advantage of the Invention] As described above, the present invention forms the required recess 4 in the door 3 of the control unit 2 provided on the side surface of the machine base, and the drawer gap 7 is opened in the recess 4 to form a frame. The body 6 is accommodated, the upper end of the frame is hinged to the upper part of the recess and hung so as to move upward in a fan shape, and a damper 9 for holding is provided between the frame 6 and the recess side part 4a. Since the transparent cover plate 12 is hinged to the surface of the body 6 so as to be openable and closable, and the operation panel 10 having the setting panel in the lower frame of the cover plate 12 is attached separately from the control device 11, Since the door can be opened and closed together with the operation panel, even if the operation panel is located in front of the control unit, there is no inconvenience for maintenance and inspection of the control unit. In addition, the operation panel is separated from the control device and attached to the door, so the weight of the operation panel is lighter than when it is integrated with the control device. When exchanging, the operation panel can be removed from the frame and exchanged. Since it is not necessary to remove the butterfly plate and the damper one by one as in the conventional case, the work is simple and the labor is not required.

In addition, since it has a cover plate, it can prevent the setting panel from being contaminated by oil, etc., and accidentally touching it, dropping other objects, etc. will cause malfunctions without knowing it, and the setting values will be changed or damaged. It has the advantages that it can be prevented in advance and safe operation can be carried out.
