JP3032972U - Rotation mechanism for operation panel of injection molding machine - Google Patents

Abstract

(57) [Abstract] [Problem] To rotate an operation panel for attaching and detaching a screw of an injection device, but the operability may be extremely poor depending on the rotation angle, and the rotated operation panel may be securely fixed. I could not do it. SOLUTION: A shaft tube provided on the bottom surface of the operation panel is fitted into a seat tube provided on a pedestal on the side of a fixed board to make the operation panel rotatably, and a pin of a stopper provided on the front surface of the pedestal is used for the seat. Rotation of the operation panel is prohibited by inserting the through hole of the pipe and the positioning hole of the shaft pipe.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a mechanism for rotating an operation panel for accommodating an operation of an injection molding machine, an input device of set values, a display, and the like and fixing the operation panel at a predetermined position.

[0002]

[Prior art]

 As disclosed in Japanese Utility Model Publication No. 6-1394, since the conventional operation panel accommodates a large volume CRT, it cannot be installed on the side of the fixed panel with good operability. However, due to the recent advances in electronic technology, small display devices such as liquid crystal panels can be adopted, and as disclosed in Utility Model Registration No. 3022035, installation on the side of the fixed plate becomes possible.

[0003]

[Problems to be solved by the invention]

 However, even in the utility model registration No. 3022035, which has good operability during normal molding, the operation panel becomes an obstacle when the screw of the injection device is detached, so the operation panel is rotated. However, the operation panel in that case was extremely difficult to operate because the operation surface faces the back side. Further, since the operation panel does not have a stopper for rotation, there is a problem that the operation panel becomes unstable due to operation of a push button switch or the like.

[0004]

[Means for Solving the Problems]

 Therefore, a seat tube fixed to the upper surface of the pedestal on the side of the fixed plate and having one through hole in the front of the gantry, and a plurality of positioning holes that are fitted into the inner surface of the seat tube and are provided at the same height as the through holes are provided. The operation panel has a shaft tube on the bottom and a stopper that allows the pins inserted into the through holes and the positioning holes to move forward and backward from the front surface of the gantry so that the electric wires to the operation panel can pass through the shaft tube. I did it.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view showing a main part in the vicinity of a fixed plate of the injection molding machine, and FIG. 2 is a front view in FIG. 3 is a partial sectional view taken along the line AA in FIG.

Reference numeral 1 denotes a frame on which the mold clamping device 16 and the injection device 17 of the injection molding machine are mounted. Reference numeral 2 denotes a fixed plate that constitutes a part of the mold clamping device 16, and fastens four stays 3 that connect a movable platen with a mold clamping force generating device such as a mold clamping cylinder (not shown), and a fixed metal plate. Attach the mold 14. Reference numeral 17 denotes an injection device, which is composed of a heating cylinder 4, a nozzle 15 screwed at the tip thereof, a screw fitted in the heating cylinder, etc., and the screw can be reciprocally rotated by a plasticizing and injection drive device (not shown). The plasticization and injection filling of the raw material resin is performed. The injection device 17 has a mechanism capable of reciprocating on the pedestal 1 with respect to the fixed mold 14. The nozzle 15 is brought into contact with the fixed mold 14 to melt the molten resin accumulated in the heating cylinder with a screw. It is injected and filled in the mold. Further, the ejecting device 17 has a turning mechanism for turning the heating cylinder 4 to the state of 4a, and is advantageously used for the attachment and detachment of the screw and the maintenance and inspection of the heating cylinder 4. At this time, the heating cylinder 4 is retracted by the reciprocating mechanism and is then rotated counterclockwise by the swivel mechanism at the position 4a, and the operation panel 5 is rotated counterclockwise about the shaft tube 18. Then in position 5a. The heating cylinder 4a and the operation panel 5a are parallel to each other with a distance not in contact with each other, and the operation panel 5a has a rotation angle of about 30 degrees, which has no influence on the operability.

The operation panel 5 includes a display 7 of a liquid crystal panel, a setting device 8 for inputting a set value in cooperation with the display 7, and an operation device 9 for manual operation of the injection molding machine. It is housed in a single case. The operation panel 5 is provided with a shaft tube 18 on its bottom surface, and its mounting base 20 is larger than the outer diameter of the shaft tube 18. The seat tube 19 has an inner diameter that fits into the outer diameter of the shaft tube 18, and an end of the seat tube 19 slightly projects from the mount surface into a hole provided on the mount 1 on the side of the operation surface of the fixed platen 2. It is welded to the pedestal after it has been inserted. A through hole 26 is bored in front of the operating surface of the seat tube 19 located inside the gantry 1. The shaft tube 18 is fitted into the seat tube 19 and the mounting base 20 of the shaft tube 18 is attached to the end surface of the seat tube 19. In the abutting state, a plurality of positioning holes 27 communicating with the through holes 26 are provided on the circumference of the shaft tube 18 at a predetermined angle. The position of the positioning hole 27 is such that the operation surface of the operation panel 5 is the front side of the operation side of the gantry 1, and the operation panel 5 is rotated counterclockwise so that the operation panel 5a does not contact the heating cylinder 4a. It is preferable to turn the operation panel 5 to the above position so that an operator standing in front of the safety door 6 of the mold clamping device can easily visually recognize the operation panel 5 by rotating the operation panel 5 clockwise.

The pin 11 of the stopper 10 is inserted into the hole through which the through hole 26 and the positioning hole 27 communicate with each other to inhibit the rotation of the shaft tube 18. A knob 22 for pushing and pulling the pin 11 is fixed to the other end of the pin 11 which penetrates the seat 24, and a step portion 12 is provided in the middle of the knob 22, and the step portion 12 and the seat 24 are connected to each other. A coil spring 13 for elastically ejecting the pin 11 in the direction of the through hole 26 is inserted therebetween. The seat 24 is mounted by screwing the stopper 10 into the mounting hole 25 provided in the gantry 1. Reference numeral 23 is a cylinder for guiding the stepped portion 12, and is fixed to the seat 24. When the knob 22 is pulled, the tip of the pin 11 comes out of the positioning hole 27 of the shaft tube 18, the operation panel 5 becomes rotatable, and when another positioning hole appears by rotating a predetermined angle, the pin 11 becomes a coil spring. It is raped by 13 and inserted into the positioning hole to prohibit rotation.

A hole that connects the inside of the shaft tube 18 and the inside of the operation panel 5 is provided at the bottom of the operation panel 5 to which the shaft tube 18 is fixed. The electric wire 21 connected to is inserted.

[Effect of the invention]

 The operation surface of the operation panel is located at a position where operability is good, and even when the heating cylinder is swiveled, the screw can be removed and the maintenance and inspection of the heating cylinder can be performed without impairing operability. Further, since the operation panel is securely fixed by the stopper that prohibits the operation panel from rotating at a plurality of predetermined rotation angles, the operation of the injection molding machine can be easily performed.
