  In the present embodiment, the facing surface 20 of the thermoformed plate 21 fixed to the fixed platen 13 is also formed substantially the same as the facing surface 24 of the thermoformed plate 25 that is an intermediate plate shown in FIG. As for the facing surface 22 of the thermoforming plate 23 fixed to the movable platen 19, the molding surface 27 is similarly formed with the separator molding portion 28 and the surplus portion molding portion 29. Since it is provided, the guide hole is not provided, and the disc spring 33 is not provided. In the following description, the reference numeral of the thermoformed plate 25 that is an intermediate plate is also used for the molding surfaces 27 of the thermoformed plates 21 and 23.

  Above the heat-molded plates 21, 23, 25, there are disposed resin plate feeding mechanisms for feeding the resin plates P between the opposed surfaces 20, 22, 24 of the heat-formed plates 21, 23, 25, respectively. Yes. The resin plate loading mechanism is fixed to the upper part of the fixed platen 13. In the resin plate loading mechanism, ten loading ports 47 are formed at positions above the gap formed between the opposing surfaces 20, 22, and 24 when the mold is opened. The inlet 47 is provided in parallel with the opposing surfaces 20, 22, 24, and the two guide plates 40, 40 are gradually narrowed toward the gap formed between the opposing surfaces 20, 22, 24. The upper tie bar 16 is composed of two guide plates 39, 39 whose intervals are gradually narrowed downward. In addition, even if the interval between the opposing surfaces 20, 22, and 24 is 4 mm, the insertion port 47 can insert the resin plate P between them and perform accurate positioning. The resin plate loading mechanism can eliminate the guide plate as long as it is a gripping mechanism that holds each resin plate in line with the center-to-center spacing between the thermoformed plates when the mold is opened and can be positioned accurately. Can be changed.

  A molded product receiving mechanism for receiving the molded product S released by the molded product release mechanism is disposed below the thermoformed plates 21, 23, 25. In the present embodiment, a receiving plate 42 that is lifted and lowered by a lifting cylinder device 41 is disposed as a molded product receiving mechanism. On the upper surface of the receiving plate 42, holding portions 43 are formed at 10 locations corresponding to positions below the gap formed between the opposing surfaces 20, 22, 24 when the mold is opened. . And the holding | maintenance part 43 can receive the released molded product S, without making it contact with the other molded product S in the standing state. Further, a hole is formed in the receiving plate 42, and the guide bar 44 is inserted to prevent the receiving plate 42 from being displaced in the lateral direction. The molded product receiving mechanism may be configured such that the molded product is conveyed as it is by a conveyor, and other appropriate changes are possible.

  Next, molding of the fuel cell separator by the press device 11 of the present embodiment will be described. The resin plate P used in the present embodiment contains 70% carbon and contains a thermoplastic resin as a binder. The carbon content is preferably 50 to 90%, and the binder may be a thermosetting resin. The outer dimension of the resin plate P is formed slightly larger than the outer dimension of the separator molding portion 28, and the plate thickness is 1 mm. The thickness of the resin plate P is preferably 0.5 to 2.0 mm. First, as shown in FIG. 1, when the resin plate P is introduced, the thermoformed plates 21, 23, 25 are opened, and the positioning plate 34 is inserted into the insertion hole of each thermoformed plate 21, 23, 25. Done in state. As shown in FIG. 3, when the resin plate P is introduced through the resin plate introduction mechanism, the resin plate P is guided to the guide groove portions 31 such as the guide plates 39 and 40 of the resin plate introduction mechanism and the thermoforming plate 25. Then, it falls onto the positioning plate 34 and is positioned with respect to the molding surface 27. The resin plates P may be charged all at the same time or sequentially. In the present embodiment, the outer dimension of the resin plate P is formed slightly larger than the outer dimension of the separator molding part 28, and the surplus part molding part 29 is provided around the separator molding part 28. Even if the resin plate P introduced from the insertion port 47 is slightly displaced due to an impact when it collides with the positioning plate 34, the formation of the fuel cell separator S1 by the separator forming portion 28 is not affected.

  When the resin plate P is inserted between the opposing surfaces 20, 22, 24 of the thermoformed plates 21, 23, 25, as shown in FIG. 4, the hydraulic cylinder device 15 is operated to close the mold in the horizontal direction. . At that time, after the resin plate P is sandwiched between the protruding portions 30 at the boundary between the separator molding portion 28 and the surplus portion molding portion 29, the rod 37 of the moving cylinder device 36 is contracted to form the thermoforming plates 21, 23, 25. Then, the positioning plate 34 is retracted and removed. Then, the positioning plate 34 is extracted, and the insertion holes 35 are opened in the thermoformed plates 21, 23, 25. However, the thickness of the resin plate P is 0.5 to 2.0 mm as described above. Since the surplus part S2 is formed through the thin part formed by the protruding part 30, the behavior of the resin in the separator molding part 28 is not affected, and a large amount of resin enters the insertion hole 35. There is nothing. Further, even if the temperature of the portion of the insertion hole 35 of the thermoformed plates 21, 23, 25 is lowered, it does not reach the separator molding portion 28.

  Then, the mold is further clamped in the horizontal direction by the hydraulic cylinder device 15, and when the resin plate P is heated and pressurized via the thermoformed plate, the surface of the resin plate P is melted, and the melted resin Is filled to every corner of the uneven surface of the separator molding portion 28. In addition, the melted resin other than that filled in the separator molding portion 28 is extended in the surplus portion molding portion 29 to such an extent that the entire surplus portion molding portion 29 is not filled.

  Immediately before the completion of heating / pressurization, the lifting / lowering cylinder device 41 of the molded product receiving mechanism is operated, and the receiving plate 42 is raised toward the heated molded plates 21, 23, 25. Next, when the hydraulic cylinder device 15 is actuated to release the clamping force, as shown in FIG. 5, the space between the thermoformed plates 21, 23, 25 is 4 mm due to the elastic force of the disc spring 33 of the mold interval maintaining mechanism. Opened at intervals. Therefore, in this embodiment, the molds of the thermoformed plates 21, 23, 25 can be opened by a simple mechanism. The mold opening movement of the movable platen 19 by the hydraulic cylinder device 15 is performed and stopped until the movable platen 19 is detected by the limit switch 45. Then, after completion of the mold opening movement, air is ejected from the air outlet 32 of the thermoformed plates 21, 23, 25 toward the surplus portion S2 of the molded product S, and from the molding surface 27 of the thermoformed plates 21, 23, 25. The molded product S is released and falls. The dropped molded product S is received in a standing state such that the molded products S do not contact each holding portion 43 of the receiving plate 42 of the molded product receiving mechanism. Then, the raising / lowering cylinder device 41 is lowered and the molded product S is completely taken out from between the thermoformed plates 21, 23, 25. Next, the taken-out molded product S is taken out to the next process, and the fuel cell separator S1 and the surplus portion S2 are separated.

  Next, maintenance of the press device 11 will be described. In the molding of the fuel cell separator, a part of the resin may adhere to the molding surface 27, and the molding surface 27 needs to be maintained at that time. However, in the press device 11, the distance between the thermoformed plates 21, 23, 25 opened and held by the disc spring 33 is 4 mm as described above, so that the thermoformed plates 21, 23, 25 are formed as they are. It is difficult to perform maintenance such as cleaning of the surface 27. Therefore, the press device 11 uses a booster type hydraulic cylinder device 15 that can take a long mold opening stroke so that the distance between the thermoformed plates 21, 23, 25 can be widened during maintenance. Bolt holes 46 are formed at the same height on the side surfaces of the thermoformed plates 21, 23, 25, the fixed platen 13, and the movable platen 19. In addition, an inspection bar (not shown) having a predetermined length and having holes at predetermined intervals is separately prepared for maintenance.

  When the molding surface 27 to be maintained at the time of mold opening at the time of molding is a surface directed to one side (surface on the fixed platen 13 side), the thermoforming plate 25 having the molding surface 27 and the movable platen 19 Fix the gap to the inspection bar. For fixing the inspection bar, a bolt inserted into the hole on the other side of the inspection bar is screwed into the bolt hole 46 of the movable platen 19 and a bolt inserted into the hole on one side of the inspection bar is inserted into the thermoforming plate 25. This is done by screwing into the bolt hole 46. When the inspection bar is fixed, the hydraulic cylinder device 15 is operated in the mold opening direction, and the thermoformed plate 25 fixed together with the movable platen 19 is moved. When the molding surface 27 to be maintained is a surface facing the other side (surface on the movable platen 19 side), check between the thermoformed plate 25 on the side facing the molding surface 27 and the movable platen 19. Fixing by the bar, the hydraulic cylinder device 15 is operated in the mold opening direction, and the thermoformed plate 25 fixed together with the movable platen 19 is moved. Thus, a wide inspection space can be secured between the molding surface 27 to be maintained and the other thermoformed plate 25 facing the molding surface 27 or the like. Further, when performing maintenance on the molding surface 27 of the thermoforming plate 23 fixed to the movable platen 19 or the molding surface 27 of the thermoforming plate 25 opposed thereto, only the movable platen 19 is moved to open the mold without attaching an inspection bar. . When maintenance of the molding surface 27 directed to the other side of the thermoforming plate 25 is performed, the maintenance of the molding surface 27 is further improved by fixing the space between the fixed platen 13 and the thermoforming plate 25 to be maintained with an inspection bar. It can be done reliably.

  Further, the present invention is not enumerated one by one, but is not limited to that of the above-described embodiment, and it goes without saying that the present invention can be applied to those modified by a person skilled in the art based on the gist of the present invention. That is.
