A lower hot plate 6 is fixed with tightening bolts 7, and an intermediate hot plate 8 is supported by a counter cylinder 9 at the upper part provided with a port for carrying in and out of the molded material, and an upper hot plate 10 is attached to the uppermost part. is fixed by a tightening port 14 to an upper bolster 13 which is thermally insulated by an upper heat insulating plate 11 and connected to the press body 1 by a column 12. This hot press has lower heating plate 6
and intermediate hot plate 8 and between intermediate hot plate 8 and upper hot plate 10, a second
As shown in the figure, a prepreg 16 is sandwiched between printed wiring boards of a molded object 15, and a multilayer printed wiring board formed by upper and lower jig plates 17 and 18 and a plurality of guide pins 19 is formed. At the same time, the heating device 20 applies forming heat energy to each hot plate 6, 8, and 11.
A predetermined hydraulic pressure is supplied to the ram cylinder 2 and the counter cylinder 9 by a hydraulic device 21, and the molded object 15 is bonded under pressure.

upper and lower jig plates 17 for fixing the molded object 15 sandwiched between the upper and lower jig plates 17;
．． 18 is required to have parallelism and flatness of 0.03 x 17 m or less for a length of 500 mm from the viewpoint of accuracy since it directly contacts the molded object 15. However, the upper and lower jig plates 17 and 18 are subject to warping and local wear due to heat cycles during molding, abrasion during transportation, and disassembly work after molding, resulting in uneven pressure distribution during molding, Due to local elongation and the like, variations in the dimensions of the printed circuit board of the multilayer printed wiring board of the molded object 15 become large.

18 periodic accuracy measurements are carried out, and if the accuracy falls outside the control level, it is corrected or re-sharpened. However, the cost of sinking pipes, the cost of manufacturing new jig plates, etc. account for a high proportion of the manufacturing cost of the molded product, and a solution to these problems has been desired.
本発明の目的は上記の点に鑑み原価低域を図るようにし
た多段形ホットプレスを提供することを目的とする。SUMMARY OF THE INVENTION In view of the above points, it is an object of the present invention to provide a multi-stage hot press which is designed to reduce the cost.

た穴２７に嵌入されてｂる。Reference numeral 22 denotes a plurality of positioning guide pins inserted into a plurality of molded objects 15 such as printed wiring boards, and a tapered portion 22a is formed on the tip side of this kite pin 22. 23 is the tapered portion 2 of the kite pin 22 for positioning 6;
This bushing 23 is provided on the upper side of the lower heating plate 6 and the intermediate heating plate 8, for example, as a bushing of the fitting portion 2af. 241''i When the lower hot plate 6 and intermediate hot plate 8 rise due to the stroke of the ram 3 of the ram cylinder 2, this piston 24 presses down the rear end side of the kite pin 22 by the reaction force of the spring 25, and the piston 24 is pulled out. The retaining ring 26 is fitted into a hole 27 formed at the lower side of the intermediate hot plate 8 and the upper hot plate 10.
次に本発明の詳細な説明する。Next, the present invention will be explained in detail.
まず接着準備作業として、被成形物１５及びプリプレグ

する。このようにして被成形物１５を中間熱板８．８の
間に挾持する。First, as a bonding preparation work, taper portions 22 with the same diameter and the same number of holes on the hot plate insertion side are made in the molded object 15 and the prepreg 16.
The molded object 1 is placed on the positioning guide pin 22 provided with a.
5 and the prepreg 16 are alternately made into a multi-Jfii structure, and this is inserted into the tapered hole of the bushing 23 fitted on the hot plate 8. In this way, the object to be formed 15 is held between the intermediate hot plates 8.8.
次に油圧装置１６を駆動し、シリンダー２に油圧を供給

形物１５が加圧される。Next, the hydraulic device 16 is driven to supply hydraulic pressure to the cylinder 2, and the ram 3 raises the lower bolster 4 and the lower heating plate 6, which is thermally sealed by the heat insulating plate 5 on the lower bolter star 4. The object to be formed 15 on the lower hot plate 6 comes into contact with the upper hot plate 10 and the upper hot plate 10 is further raised. The object 15 is pressurized.
この加圧と開時にガイドピン２２の真上の熱板内に設け

２２の加圧機構のばね力によりカイトピン２２を熱板上
のブツシュ２３の精度に倣い正しく位置決めされる。When this pressure is applied and when the guide pin 22 is opened, the spring force of the pressure mechanism of the guide pin 22, which is provided in the heat plate directly above the guide pin 22 and is made up of a spring 25 and a piston 24, moves the kite pin 22 to the precision of the bush 23 on the heat plate. It will be positioned correctly according to the following.
その後加熱冷却制御装置２０の接着条件に従い油圧、温
度が制御され、被成形物１５は成形される。Thereafter, the oil pressure and temperature are controlled according to the bonding conditions of the heating/cooling control device 20, and the molded object 15 is molded.
このように、高剛性のため積度低下しにくい熱板６，８

１の発生がなく、被成形′吻１５の寸法変化のばらつき
が小さい、高精度のものが得られる。In this way, the hot plates 6 and 8 have high rigidity and are difficult to reduce.
If molding is performed directly on the hot press, a uniform pressure distribution and temperature distribution can be obtained, and since the correct position of the molded object 15 is always at the center of the hot press, side loads 1 due to the inclination of the hot plate 6°8 etc. It is possible to obtain a high-precision product in which there is no occurrence of dimensional changes in the proboscis 15 to be formed, and the variation in dimensional changes is small.
ちなみに１、本発明の熱板６．８は、従来の治具板に比
較して約３〜５倍の寿命向上が図れる。Incidentally, 1. The hot plate 6.8 of the present invention can improve the lifespan by about 3 to 5 times compared to the conventional jig plate.
本発明の多段形ホットプレスによれば、被成形物の寸法
変化のばらつきは約３０％低減可能であると共に治工具
費の低減は約６０％に達成可能であるため、大幅な原価
低減が大幅に図れる。According to the multistage hot press of the present invention, it is possible to reduce the variation in dimensional changes of the molded object by about 30%, and it is also possible to reduce jig costs by about 60%, resulting in a significant cost reduction. can be achieved.
したがって、被成形物として多層プリント配線基板など
を用いた場合、被成形物の液溜作業の原価低減に大きな
効果を発揮する。Therefore, when a multilayer printed wiring board or the like is used as the object to be molded, it is highly effective in reducing the cost of liquid collection work for the object to be molded.
