ット４ａに孔全形成するためのピンである。As shown in FIG. 9, the segments with through-holes formed in this way are polymerized so that the through-holes coincide, are placed in an injection mold, and are molded by injecting the bracket and fixing resin. , according to FIG. 9, N1-N3
To explain the case of injection molding of a part as an example, through holes 6c, 6d, and 68 for fixing are formed in segments) 2a and 2d, and through holes 5b' for a bracket are formed in segment) 2d.
After forming the molten resin between the cavity mold 7 and the core mold 8, and positioning and fixing with the pin 9, the plate 10 is closed and the molten resin is injected from the runner 11 through the entire gate 12. The cavity space formed by the mold 8 and the segments 2a and 2d is filled with resin to form the bracket 4a, and the fixing resin 6a is formed to form the segment 2a.
, 2d are fixed to form the frame 2. 13 is a pin for forming all the holes in the bracket 4a.

As shown in FIG. 6, the L, -T, and 2 portions may be entirely formed using a bonding resin 3g in which a plurality of through holes are filled with resin and the resin is continuous on both sides of the segment. The fixing material 44 may be used in common with the bracket, as shown in the M and -M2 portions in FIG. That is, in FIG. 7,
- The fixing resin 6N) is provided at the overlapping portion of the segments 2a and 2b and also functions as a bracket.
