題等があげられる。 By the way, there are many problems in producing the above-mentioned eyeglass frames as actual products. For example, it is difficult to stabilize the position of reinforcing fibers embedded in the synthetic resin, and the thickness of the synthetic resin is uneven, making frame members such as front frames or temples that require thinness. In this case, there is a problem that the strength after forming is not stable, and some of the reinforcing fibers protrude from the outer surface of the frame member during molding or polishing during finishing. Furthermore, since the color and pattern of the frame member are determined by the method of coloring the synthetic resin in which the reinforcing fibers are embedded, there is another problem that the frame member must be simple.

る。 Next, a method of forming the front frame 1 will be explained. That is, as shown in FIG. 3, the first molding lower mold 9 is used to form the first front frame body 1a having a smaller shape than the desired shape of the front frame 1, The reinforcing fibers 8 are arranged along the line. On the other hand, as shown in FIG. 4, a groove 12 is formed in the first molding upper die 11 in the shape of the first front frame body 1a, and a hole 18 is formed in the right end of the groove 12, and a hole 18 is formed in the right end of the groove 12. A hole 14 is formed deeper than the groove 12 in the end portion, a hole 15 in the right pad portion, and a hole 16 in the left pad portion. Then, hinge parts on the front frame side constituting the hinge are respectively inserted into the holes 13 and 14 so that the mounting bases (not shown) of the hinge parts are in the groove 12, and the holes 15 and The pads 6 and 7 are respectively inserted into the groove 16 such that the mounting bases (not shown) of the pads 6 and 7 are located within the groove 12.

を形成する。 In this way, after placing each member in the lower mold 9 and upper mold 11 for the first molding, the lower mold 9 and the upper mold 11 are placed in the groove 1.
After aligning the molds so that 0 and 12 match and further clamping the molds, a synthetic resin such as polyurethane, epoxy or polyamide is injected into the grooves 10 and 12, impregnated into the reinforcing fibers 8, and the synthetic resin is cured. However, as described above, the first front frame body 1a has a smaller shape than the desired shape of the front frame 1.

トフレーム１を形成する。 Next, the first front frame body 1a is inserted into the groove 18 formed in the second lower mold 17. This groove 18 is formed so as to form the shape of the front frame 1 of a desired size.
As shown in the figure, the inner side of the lens attachment part 1b of the front frame body 1a is joined to the inner wall 18a of the groove 18, and the groove 18 has holes 19, 20, 21, 22 into which the hinge members and pads are inserted.
, so that the front frame body 1a can be positioned with respect to the groove 18. In this state, an upper mold (not shown) is placed on the lower mold 17, and a synthetic resin such as polyurethane, epoxy or polyamide is injected into the groove 18 in the same manner as in the first molding, and the first front frame body 1a is formed. A synthetic resin layer is formed on the outer periphery, and the synthetic resin is cured to form the front frame 1 of a desired size.

ンプルを成形するのである。 The front frame 1 is formed as described above, and the temples 2 and 3 are formed in the same manner. That is, although not shown in the drawings, a temple body having a smaller shape than the desired shape is attached to the temple side hinge part and molded from fiber-reinforced synthetic resin in advance in a first molding process, and then in a second molding process. A temple of a desired size is molded by placing the first temple into a mold and providing a synthetic resin layer around the outer periphery of the first temple.
尚、上記実施例では、強化繊維として長繊維を
