It is common to use However, the structure of the composite material manufactured by such a method is a flat plate material in which a resin layer is simply formed between metal plates, and does not realize various shapes such as punching and drawing. Therefore,
In order to form such a composite material into a shape that matches the target object, it is necessary to perform secondary processing such as punching and bending on a flat plate-shaped sandwich steel plate, and the work becomes extremely complicated. I was

る。Also, as another manufacturing method for manufacturing sandwich steel plates,
There is a manufacturing method proposed by the present inventors, that is, a manufacturing method in which composite materials of various shapes are manufactured by combining sheet metal pressing and resin injection processing (Japanese Patent Application Nos. 61-224223 and 62-1987).
211322). Specifically, two metal plates to be formed are placed in a state of being stacked between a movable die having a concave and convex portion such as a pair of press working punches and dies and a fixed die, and the movable die is moved. First, press working is performed, and then, while holding the metal plates one by one in each die, the movable die is moved in the direction of releasing the mold, and a cavity having a predetermined width is provided between the two metal plates. Alternatively, a cavity is formed outside the metal plate through a hole formed by press working, and a molten resin is injected and injected into the cavity to form a resin layer. And
The composite material molded product is taken out after the resin layer is solidified.

昭63−11873号）。In addition, the inventors of the present application have further improved the above-mentioned manufacturing method, and have performed different press workings on each of two molded plates among three molds that can be simultaneously clamped to remove an intermediate mold. A method is also proposed in which a cavity is formed between the plates to be molded and then filled with a synthetic resin (Japanese Patent Application No. 63-11873).

It became possible.

材の側端部に合成樹脂や金属等からなるヒンジを固定す

場合においても同様である。[Problems to be Solved by the Invention] By the way, as a method of connecting the two members so that they can be bent and displaced (for example, the connection relationship between the box and the lid), a synthetic resin, metal, or the like is attached to the side end of each member. Is generally fixed, and the same applies to the case where the above-mentioned sandwich steel plates are connected.

倒なものとなっている。However, when fixing the hinge, it is necessary to perform fixing work such as screwing or bonding, and in particular, when fixing by screwing, it is necessary to make a hole in the metal plate covering the resin layer in advance, so that fixing The work is very troublesome.

一方、樹脂成形品においては、射出成形によって屈曲
変位可能なヒンジ部を設けることが可能であり、別部材
としてのヒンジを必要としないので、多くの樹脂製品に
この手法が多用されている。On the other hand, in a resin molded product, a hinge portion that can be bent and displaced can be provided by injection molding, and a hinge as a separate member is not required. Therefore, this method is frequently used for many resin products.

が煩雑となり、その生産性の向上に限界がある。However, in a sandwich steel plate, since the surface of the resin layer is covered by bonding a metal plate, it is necessary to process the metal plate in order to provide a hinge portion made of the synthetic resin. Therefore, in a method of manufacturing a sandwich steel sheet in which a metal plate is bonded to an injection-molded synthetic resin, a processing operation is complicated, and there is a limit to improvement in productivity.

To provide a mold.
