Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a movable frame used for a press device or the like.
[0002]
[Prior art]
In a heat press for pressing and molding plates, powders, fibers, foils, etc. of organic substances, inorganic substances, metals, etc. or composite materials thereof at a high temperature, a movable frame for forming a vacuum or an inert gas atmosphere is provided by the present applicant. Developed and used.
This movable frame uses a pair of frames, one of which can penetrate the other, interposed between heating press plates via a seal.

[Problems to be solved by the invention]
However, the conventional movable frame does not have a driving device for moving the frame up and down, and when the pressurization of the press is removed, the movable frame is extended upward by a spring, which hinders the loading and unloading of the work. In some cases, such work was hindered.
The present invention aims to remedy the disadvantages of the prior art.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the movable frame of the present invention contacts a surface on which an object is placed via a seal, and forms a first space forming a predetermined space, and penetrates or enters the first frame. A second frame that penetrates the first frame and is movable relative to the first frame; a sealing device that slidably seals between the first frame and the second frame; A moving device for relatively moving the first frame and the second frame.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, a movable frame is provided between an upper heating press plate 50 and a lower heating press plate 51, and a workpiece W to be processed is inserted into the movable frame.
The movable frame includes an outer frame 1 and an inner frame 2. The outer frame 1 contacts the upper heating press plate 50 and is sealed by the packing 5. The inner frame 2 is placed on the lower heating press plate 51, and the space between the inner frame 2 and the lower heating press plate 51 is sealed by the packing 4.
It is preferable that the outer frame 1 and the inner frame 2 have a cylindrical or rectangular cylindrical shape, and in this embodiment, they are basically rectangular cylindrical.
[0007]
The outer frame 1 penetrates the outer peripheral side of the inner frame 2. That is, the upper end of the inner frame 2 is configured to penetrate into the inner peripheral side of the outer frame 1.
A packing 3 is provided on the outer periphery of the upper end portion of the inner frame 2 so as to seal between the outer periphery of the inner frame 2 and the inner periphery of the outer frame 1.
[0008]
Four air cylinders 6 are provided on the side of the inner frame 2, and are configured to vertically move the outer frame 1 up and down.
As shown in FIG. 4, an air cylinder pipe 10 is connected to the air cylinder 6, and is connected to a driving source via the air cylinder pipe 10.
[0009]
The outer frame 1 can be arbitrarily moved with respect to the inner frame 2 by the air cylinder 6, and the outer frame 1 can be held at an arbitrary position.
[0010]
FIG. 1 shows a state in which the outer frame 1 is held at the highest position. From this state, the work W is pressed by lowering the upper heating press plate 50. The upper heating press plate 50 comes into contact with the outer frame 1 via the packing 5 and descends. As the upper heating press plate 50 descends, the outer frame 1 also descends, descends to the lowest position, and has almost the same height as the inner frame 2. This state is the state shown in FIG.
In this state, a sealed space is formed by the outer frame 1, the inner frame 2, the upper heating press plate 50, and the lower heating press plate 51, and the sealed space is pulled to a negative pressure by a vacuum device (not shown) to perform a predetermined operation. Execute
[0011]
When the operation is completed, the upper heating press plate 50 is raised. As shown in FIG. 3, at this time, if the position of the outer frame 1 is held at the lowest position by the air cylinder 6, the distance between the upper end of the outer frame 1 and the upper heating press plate 50 increases, and the work W Work such as taking out becomes easy.
[0012]
In the embodiment shown in FIG. 5, the number of the air cylinders 6 is reduced to one on one side, and the links 20, 20 are driven by one air cylinder 6 to smoothly move the outer frame 1.
[0013]
In the embodiment shown in FIG. 6, an air chuck 31 is provided on the air cylinder 6, and the pin 32 is locked to suppress the rise by the spring 30, so that the lowermost position of the outer frame 1 can be maintained.
[0014]
【The invention's effect】
As described above, according to the movable frame of the present invention, there is an effect that workability is improved.
