0, when the movable platen actuator 112 moves the movable platen 101 downward, the lowest pressurized body 103 is placed on the lower heating platen 106, and then the intermediate heating platen 104 is placed on top of it. Finally, the intermediate heating plates 104 and pressurized bodies 103 of all stages are stacked to be pressurized and heated.

When the upper heating plate actuator 112 moves upward, the uppermost pressurized body 103 rises, and then the intermediate heating plate 104 and the locking portion of the heating plate hanger 111 engage, and the intermediate heating plate 104 rises. do. At this time,
Equal intervals are provided between each pressurized body 103 and each intermediate heating plate 104.

Another example of a multi-stage hot press is a multi-stage hot press 120 as shown in FIG. The multi-stage hot press 120 includes a movable platen 122 below an upper fixed platen 121.
is adapted to move in the vertical direction by a movable platen actuator 123 provided below the movable platen 122. In addition, the fixed platen 121 and the movable platen 12
2 and a plurality of intermediate heating plates 124 and the pressurized body 12
5 are arranged.

A stepped plate 128 having a plurality of step portions 127 for locking the side portions 126 of the intermediate heating plate 124 is provided on the sides of the intermediate heating plate 124 and the pressurized body 125 . In addition, 129 is a rail spring, 130 is a heat insulating material, 1

According to the multi-stage hot press 120, the movable platen actuator 123 raises the movable platen 122 to bring the pressurized body 125 and the intermediate heating plate 124 into close contact with each other, thereby pressurizing and heating the pressurized body 125. After pressurizing and heating the pressurized body 125, the movable platen actuator 123 is operated and moved downward, and the side portions 126 of each intermediate heating platen 124 engage with the stepped portions of the stepped plates 128, and each They are maintained at equal intervals.

(Problems to be Solved by the Invention) However, according to the multistage hot presses 100 and 120 according to the prior art, the rail 1
09 is always in contact with the intermediate heating plate 104 via the rail hanger 110 and the flange portion 108, and the rail 131 is always in contact with the intermediate heating plate 124 via the rail spring 129, so that the intermediate heating plate 104, Since the heat of 124 is transferred to the rails 109, 131, the durability of the rails 109, 131 is reduced.

In addition, the number of parts such as the heating plate hanger 111, flange part 108, rail spring 129, and step board 128 increases, and each part becomes hot due to the intermediate heating plate 104, so if this is repeated, the parts may become loose. , the pressurized object is placed in a multi-stage hot press 100, 12.
The pressurized body 103 becomes unstable when it is moved in and out of zero or when it is pressurized or heated.

Furthermore, there are a large number of parts, and 10 heating plates are needed during heating.
There is a problem in that 4,124 of the heat is transferred to each component, increasing the heat radiation area and increasing thermal energy loss.

The present invention was developed in view of the above-mentioned problems, and its purpose is to prevent the heat of the heating plate from being transmitted to the rail during heating, and to reduce thermal energy loss during heating. The purpose of this invention is to provide a multi-stage hot press that can improve the precision of the equipment.

(Means for Solving the Problems) The present invention having the above object connects a movable platen and a fixed platen with a vertical rail hanger, attaches a plurality of rails to the rail hanger so as to be able to rise and fall, and A plurality of heat platens are arranged between the plurality of heat platens, and the plurality of heat platen locks are attached to the plurality of rails to contact the flange portions of the plurality of heat platens and hold the plurality of heat platens separately only when non-heating and non-pressure are applied. At the same time, the rail hanger is provided with a stopper for regulating the lower position of the plurality of rails, and a horizontal direction regulating member is provided for regulating the plurality of rails in the longitudinal and horizontal directions.

(Function) Therefore, in the multi-stage hot press of the present invention, the hot platen is separately suspended by the rails of each stage. When the movable platen is lowered, the rail hanger, the pressurized body, and the heating platen are lowered. In that case, the lowest pressurized member is placed on the lower heating plate first. Furthermore, as soon as the movable plate is lowered, the upper heating plate is placed on the pressurized body. As the movable plate further lowers, the heating plates ride on the pressurized objects one after another in the same way.Finally, the upper heating plate rides on the topmost pressurized object, and each pressurized object is pressurized and heated. be done.

When the movable platen rises, each heating platen and the pressurized body are lifted one after another from above at regular intervals.

As described above, since the flange portion of each heating platen and the heating platen locking body of the rail are not in contact during pressurization and heating, the heat of the heating platen is not transferred to the rail.

Furthermore, even if the heating plate moves and comes into contact with the rail after heating is finished, and the heat from the heating plate is transferred to the rail, this heat will be transmitted through the rail hanger that guides the rail and dissipated to the fixed plate, movable plate, etc. This prevents rail temperature rise and deformation.

In addition, the rail alone serves both to hold the pressurized member and to hold the heating plate when not pressurized or heated, and the rail does not undergo temperature rise or deformation due to the heat of the heating plate as described above. Since the front, rear, right and left directions of the rails in each stage are regulated by the horizontal direction regulating members, no wobbling occurs and the accuracy of the hot press can be improved.

(Example) The present invention will be explained below based on the illustrated example.

FIG. 1a shows a multi-stage hot press according to the present invention, and 1 is an overall view of the multi-stage hot press. The fixed platen 2 and the upper frame 5 of the rectangular movable platen actuator 15 are connected by connecting members 6 arranged at each of the four corners. Further, the multi-stage hot press 1 has a fixed platen 2 and a movable platen 4. A plurality of pressurized objects 7 and an intermediate heating plate 8 as a heating plate are arranged between the movable platen 4 and the fixed platen 2. 8a is an upper heating plate, 8b is a lower heating plate, and 17 is a heat insulating material.

The movable platen 4 has a connecting member 6 inside the connecting member 6.
A rail hanger 9 extending parallel to (that is, extending in the vertical direction) is attached so as to be movable up and down simultaneously with the movable platen 4. A plurality of rails 10 whose downward positions are regulated by a plurality of stoppers 9a provided at predetermined intervals are attached to the rail hanger 9. It consists of a hot plate locking body 12 that locks the hot platen 8 and a pressurized body locking part 13 that locks the pressurized body 7. The heating plate locking body 12 includes
Hole 12a that locks the flange portion 14 of the intermediate heating plate 8
The hole 12a has a size that allows the flange portion 14 to move up and down.

Moreover, the rail hanger 9 as a horizontal direction regulating member is adapted to regulate the rails 10 of each stage in the front, rear, left and right directions. According to the multi-stage hot press 1 configured in this manner, when the movable platen 4 is moved downward by the movable platen actuator 15, the lowest pressurized body 7 is placed on the lower heating platen 8b. At this time, the lower part of the rail 10 comes into contact with a rail stopper 16 attached to the stationary platen 2 and is held in that position. Next, the intermediate heating plate 8 is placed on top of it, and finally the intermediate heating plate 8 of all stages and the pressurized body 7 containing the pressurized object are stacked, and the upper heating plate 8a, the lower heating plate 8b, and the intermediate heating plate 8 are stacked. It is designed to be pressurized and heated by a heating plate 8. At this time, there is no contact between the intermediate heating plate 8 and the heating plate locking body 12 of the rail 10, and between the pressurized body 7 and the pressurized body locking part 13 (the two-dot chain line in FIG. 1a), the heat of the intermediate heating plate 8 is not transferred to the rail 10. Therefore, the rail 10 is not deformed due to temperature rise, and its durability is improved, and thermal energy loss is reduced.

When the movable platen 4 is moved upward by the upper heating platen actuator 15 when the multi-stage hot press 1 is opened, the rail 10 stops at a preset position on the rail hanger 9, and each intermediate heating platen 8 and the pressurized body 7 are maintained with equal intervals between them. The intermediate heating plate 8 is suspended by rails 10 at each stage. In this state,
The intermediate heating plate 8 and the intermediate heating plate locking body 12 contact each other only at the flange portion 14 of the intermediate heating plate 8 (see FIG. 1b).
solid line).

Then, the residual heat of the intermediate heating platen 8 is transferred to the rail 10, but this heat is transferred to the rail hanger 9 and further transferred to the movable platen 4 and the fixed platen 2, so the temperature of the entire rail part increases. There is nothing to do.

In addition, the number of parts is reduced by using the rail 10 alone to hold the pressurized member 7 and to hold the intermediate heating plate 8 in the non-heating/non-pressure state, and this rail 10 serves as the intermediate heating plate 8 as described above. There is no temperature rise or deformation due to the heat generated by the rails 8, and since the front and rear directions of the rails 10 at each stage are regulated by the horizontal direction regulating member 9, no wobbling occurs and the accuracy of the hot press can be improved.

Next, FIG. 2 shows a second embodiment of the present invention. Second
In the figures, parts having the same functions as those in the first embodiment are given the same reference numerals and will be explained. In FIG. 2, it has a fixed platen 2 and a movable platen 4, and the fixed platen 2
and the lower frame 5a of the movable platen actuator 20.
are connected to each other by a connecting member 6.

On the other hand, a rail hanger 9 is attached to the stationary platen 2 outside the connecting member 6 and extending downward in parallel to the connecting member 6. According to this embodiment, the rail 10 is restricted in the horizontal direction by the connecting member 6, and only the downward restriction is performed by the rail hanger 9.

In this embodiment, the movable platen actuator 20
The operation is the same as that of the first embodiment except that the movable platen 4 is moved upward by the movement of the movable platen 4, and the same effect is obtained, so a description thereof will be omitted.

(Effects of the invention) According to the invention as described above, the flanges of the plurality of heating plates and the heating plate locking bodies of the rails do not come into contact with each other during pressurization and heating, so the heat of the heating plates is not transferred to the rails. Therefore, thermal energy loss during heating can be greatly reduced.

Also, the heat from the hot plate is not transferred to the rail during heating and pressurizing, and even if the hot plate moves and comes into contact with the rail after heating is finished, and the heat from the hot plate is transferred to the rail, this heat will not transfer to the rail. It is transmitted through the guiding rail hanger and dissipated to the fixed platen, movable platen, etc., which prevents the rail from rising in temperature and deforming it, improving the durability of the rail.

Furthermore, the rail alone serves both to hold the pressurized member and to hold the heating plate when not pressurized or heated, and as mentioned above, the rail does not suffer from temperature rise or deformation due to the heat of the heating plate. Moreover, since the front, rear, left and right directions of the rails at each stage are regulated by horizontal direction regulating members, no wobbling occurs and the accuracy of the hot press can be improved.

In addition, there is no temperature rise or deformation of the rail, and the rail can be regulated in the front, back, right and left directions, so the accuracy of the hot press can be improved.
