A U-shaped frame 105 composed of a lower arm portion 102, a column portion 103, and an upper arm portion 104 is erected on a base 101, and a hollow shaft is formed on the lower arm portion 102. 106, the bearing plates 107 and 107 are fitted to the hollow shaft 106, the lower surface of the operation panel 108 is applied to the bearing plates 107 and 107, and the upper surface of the operation panel 108 is fixed to the upper arm 104 with a bolt 109. The operation panel 108 can be rotated around a vertical axis centered on the hollow shaft 106 and the bolt 109.

And according to FIG. 5 of patent document 1, the click mechanism which consists of a recessed part, a steel ball, and a spring is interposed between the two bearing plates 107 and 107.
That is, the operation panel 108 can be rotated around the vertical axis to change the mounting angle, and after the change, the click mechanism can be used to prevent rotation.

However, a large U-shaped frame 105 is necessary, leading to an increase in the cost of the injection molding machine.
In addition, since the click mechanism has a small restraining force, there is a possibility that the operation panel may rotate just by touching the operator's body.
Therefore, there is a demand for an operation panel mounting structure that is simpler than Patent Document 1 and has stronger rotation stoppers.

Various simple operation panel mounting structures have been proposed (see, for example, Patent Document 2).

The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. The drawings are viewed in the direction of the reference numerals.
FIG. 1 is a front view of a vertical injection molding machine according to the present invention. In a vertical injection molding machine 10, a turntable 12 is disposed on a base 11, and a mold clamping device 13 is disposed on the turntable 12. An injection device 14 is disposed on the mold clamping device 13, and an operation panel 15 is disposed at a corner of the base 11.

  FIG. 2 is a plan view of a vertical injection molding machine according to the present invention. The base 11 has an operation panel 15 at a corner where the left side 17 and the right side 18 are orthogonal to the front side 16 and the front side 16 and the right side 18 intersect. Indicates that the is placed. Reference numerals 19 and 19 denote human detection sensors as safety devices. Next, a structure for attaching the operation panel 15 to the base 11 will be described.

FIG. 3 is an exploded perspective view for explaining the mounting structure of the operation panel according to the present invention. The mounting structure of the operation panel is a swivel plate 21 for an injection molding machine (hereinafter abbreviated as a swirl plate 21) on the base 11. The revolving plate 21 is rotatably held by the ring member 22 and the operation panel 15 is placed on the revolving plate 21.
The swivel plate 21 has a first large-diameter hole 24 formed in a rectangular portion 23 having the same size as the vertical and horizontal dimensions of the bottom surface of the operation panel 15, and a trapezoidal protruding portion 25 is extended from the rectangular portion 23. A bolt hole 27 through which the bolt 26 with a knob is passed is formed in the protruding portion 25. 28 and 28 are pad materials.

A second large-diameter hole 31 is formed in the corner of the base 11 around a point (swivel center) 29 whose distance from the front side 16 is A and whose distance from the right side 18 is B. The distance A is preferably the same as the distance B. Then, surrounding the second large-diameter hole 31, female screw portions 32... (... indicates a plurality. The same applies hereinafter) and female screw portions 33.
The ring member 22 includes a third large hole 34 and a flange 35.

  If the distance A is the same as the distance B, the width W of the swivel plate 21 can be made twice that of A. The distance Y between the center of the first large diameter hole 24 and the edge may be the same as A. Thus, by setting A = B, the shape of the swivel plate 21 can be easily determined.

  The rectangular portion 23 of the swivel plate 21 is set to be the same as or smaller than the bottom surface of the operation panel 15. This is because the swivel plate 21 becomes inconspicuous and the appearance is improved.

  Further, although the overhanging portion 25 can be provided at an arbitrary location, it is desirable to extend the vicinity of the first large-diameter hole 24 and behind the operation panel 15 as illustrated. Since the knob bolt 26 is hidden by the operation panel 15, the appearance can be improved.

  FIG. 4 is a cross-sectional view for explaining the mounting structure of the operation panel according to the present invention. The swivel plate 21 is placed on the base 11 and the ring member 22 is fitted into the first large-diameter hole 24 of the swivel plate 21 from above. The ring member 22 is fixed to the base 11 with set bolts 36, 36 such as hexagon socket head bolts. Since the flange portion 35 of the ring member 22 covers the stepped portion 37 of the first large-diameter hole 24, there is no fear that the turning plate 21 is pulled upward.

Next, the operation panel 15 is placed on the pad materials 28, 28 of the swivel plate 21. At this time, a conduit tube (a tube accommodating a plurality of wires) 38 extending from the bottom of the operation panel 15 passes through the second large diameter hole 31 and the third large hole 34. Then, the hexagon socket head cap bolts 39 are screwed into the bottom of the operation panel 15 from below the turning plate 21.
Thus, the swivel plate 21 on which the operation panel 15 is placed can move around the ring member 22 in the front and back direction of the drawing.

Since the ring member 22 has the pad material 28, the ring member 22 protrudes about several millimeters upward from the swivel plate 21, but when the pad material 28 is very thin or there is no pad material 28, the ring member 22 is moved to the swivel plate 21. Fully embedded in That is, it is made not to project.
By performing this process, the operation panel 15 that is the moving member can be disposed above the ring member 22 that is the fixed member.

  In addition, the overhang portion 25 and the bolt 26 with the knob indicated by an imaginary line are precisely located at the back of the drawing of the ring member 22, but are shown in an easily viewable position for convenience.

Next, the operation of the swivel plate having the above configuration will be described.

As a result, the operator M can easily monitor and operate the operation panel 15.

The swirl plate according to the present invention will be described.
FIG. 7 is a cross-sectional view of the swivel plate according to the present invention. The swivel plate 21 is used when a fixture 43 such as an operation panel is attached to the base 11 of the vertical injection molding machine or the horizontal injection molding machine so as to be capable of swiveling. A member to be used, which has a stepped hole 46 having a large-diameter hole 44 at the upper portion and a small-diameter hole 45 at the lower portion at the turning center 29. A ring member 22 having a portion 48 is pivotally attached to the base 11.
The swivel plate 21 has an upper surface 49 having a size (same or slightly smaller) corresponding to the bottom area of the fixture 43, and a set bolt 39 for fixing the fixture 43 to a portion 51 protruding from the base 11. Bolt holes 52, 52 through which 39 are passed.

Preferably, the protruding portion 51 secures a gap of about 1.0 to 5.0 mm between the lower surface 53 and the base 11 by cutting the lower surface 53 of the swivel plate 21 or the like. This is because there is no fear that the lower surface 53 slides on the upper surface of the base 11 even if the revolving plate 21 is bent.
The upper surface of the ring member 22 is desirably lowered by 0.3 to 1.0 mm from the upper surface 49 of the swivel plate 21. This can be done when the bottom surface of the fixture 43 is flat.

  Since the revolving plate 21 provided with the stepped hole 46 is only stopped on the base 11 by the ring member 22, the fixture 43 can be easily attached to the base 11 of the injection molding machine, and the equipment cost of the injection molding machine is reduced. Can be reduced.

  In addition, since the bolt holes 52, 52 are opened in the portion 51 protruding from the base 11, the equipment 43 can be attached to and detached from the revolving plate 21 attached to the base 11, and the work related to the attachment of the equipment 43 Man-hours can be reduced.

  The equipment 43 includes those having a high turning frequency and those having a low turning frequency. If the turning frequency is low, the above-described mounting structure of the turning plate 21 is sufficient. However, when the turning frequency is high, it is desirable to change to the structure described below.

  FIG. 8 is a diagram showing a modified embodiment of FIG. 7. In FIG. 8, the same parts as those in FIG. That is, to describe the change, a sliding plate 55 that surrounds the small diameter portion 48 is interposed between the lower surface 53 of the turning plate 21 and the base 11. The sliding plate 55 is preferably a resin plate such as a brass plate, an oil-containing metal, or polytetrafluoroethylene. By interposing this sliding plate 55, the swivel plate 21 can be smoothly swung and the swivel plate 21 can be raised by the thickness of the sliding plate 55, so that the lower surface 53 of the swivel plate 21 remains flat. You can do it.

  In addition, a sliding plate 56 is horizontally disposed at the boundary between the large diameter portion 47 and the small diameter portion 48 of the ring member 22, and the swivel plate 21 can smoothly rotate along the ring member 22 by the sliding plate 56. Good. The material of the sliding plate 56 is arbitrary, but if it is a brass plate or a resin plate, it has a cushioning property to a slight extent.

If the dimensional error in the height direction (axial direction) of the ring member 22 is excessive, and if it is not clear, the swivel plate 21 will rattle up and down. In addition, when the gap is insufficient, the bolts 36 and 36 are tightened to become hard, and the turning operation becomes difficult.
In this regard, if the compressible sliding plate 56 is employed, an appropriate contact between the ring member 22 and the swivel plate 21 can be ensured, rattling can be prevented, and smooth swirlability can be ensured.
In addition, it is arbitrary whether to employ both the sliding plate 55 and the sliding plate 56 or only one of them.

The injection molding machine according to the present invention may be any of electric type, hydraulic type, and electric-hydraulic type.
In addition, in the first aspect, “equal” includes not only completely flush, but also substantially flush, and may be substantially uniform.
Furthermore, in the embodiment, the operation panel is arranged at the right corner where the right side and the front side intersect, but the operation panel may be arranged at the left corner where the left side and the front side intersect. In other words, the operation panel is disposed at a location where the front piece intersects either the left or right side.

  The present invention is suitable for an operation panel mounting structure of a vertical injection molding machine.
