On the other hand, the left and right sides portion in the bottom of the rear surface 12b of frame main part 12 is not formed with sidepiece reinforced wall portion 17.As shown in Fig. 4, Fig. 6, this sidepiece reinforced wall portion 17 is formed as to link between rear surface 12b and the outer peripheral face of installation portion 11 of frame main part 12.Before and after this sidepiece reinforced wall portion 17, the size in direction becomes larger towards downside, therefore, sidepiece reinforced wall portion 17 oliquely downward tilts from the rear surface 12b of frame main part 12 and extends to the outer peripheral face of installation portion 11, direction central part before and after the outer peripheral face of the lower end arrival installation portion 11 of sidepiece reinforced wall portion 17.It addition, as it is shown on figure 3, along pole insert hole 13 centrage 13a observe from rear backsight observation time, sidepiece reinforced wall portion 17 is formed as lengthwise and more tends to upside i.e. further away from installation portion 11, then width becomes the narrowest, more tend to downside i.e. closer to installation portion 11, then width becomes the widest.The length of the above-below direction of sidepiece reinforced wall portion 17 is arbitrary, but in the present embodiment, extends to the position of the left and right sides of ring pilot hole 10 from the outer peripheral face of installation portion 11, and its upper end 17a arrives the height at the center of ring pilot hole 10.As described above, frame main part 12 has inverted cone portion 15, and the upper end in this inverted cone portion 15 is the height at the center of ring pilot hole 10.It is therefore preferable that the height of the upper end 17a of sidepiece reinforced wall portion 17 is set to the height of the upper end in inverted cone portion 15, sidepiece reinforced wall portion 17 is integrally formed throughout inverted cone portion 15.It should be noted that above-mentioned thinning part 14 is formed at the position between the sidepiece reinforced wall portion 17 of left and right, the most continuous with the side of the inner side of sidepiece reinforced wall portion 17.
The lead-frame 3 of structure as above is made up of the plastic component formed by injection moulding.The material of lead-frame 3 can be adapted for the various thermoplastic resins of injection moulding, particularly preferably the synthetic resin of the chopped fiber being mixed into a length of below 1mm is carried out injection moulding and the material that formed.The length of chopped fiber is especially preferably below 0.5mm.It should be noted that as chopped fiber, it is also possible to it is carbon fiber etc..Pole is inserted hole 13 and is formed by injection moulding, and ring pilot hole 10 is formed not by injection moulding, and is formed by the semi-finished product after shaping are carried out hole machined.
Being further illustrated the injection moulding of lead-frame 3, as shown in Fig. 7 (a), mould 51 injection moulding of the mould 50 and cavity side that front and back configure core side go out lead-frame 3.Either one of the mould 51 of the mould 50 of core side and cavity side can be arranged on front side, but in the present embodiment, the mould 50 of core side is set in front side, the mould 51 of cavity side is set at rear side.It should be noted that in Fig. 7 (a), represent die joint (PL) by reference P.And, the position of cast gate 52 be arranged at shaping after in order to form ring pilot hole 10 and removed part.Specifically, the technique projection 53 of specific length is set along the direction (along fore-and-aft direction) of the centrage 13a in pole insertion hole 13 towards rear from the core of ring pilot hole 10, and the rear end of this technique projection 53 is set to cast gate 52.Therefore, when injection moulding, resin flows into the core of the part forming ring pilot hole 10 via technique protruding 53 from cast gate 52.It should be noted that the form of cast gate 52 is arbitrary, for example, it is also possible to be tunnel gate, film gate, pin gate etc..
The flowing of resin is shown in fig. 8 by arrow.The resin flowed into via technique protruding 53 spreads with radial line from the core of the part becoming ring pilot hole 10, flows to installation portion 11 from the bottom of frame main part 12.Being formed with pole at installation portion 11 and insert hole 13, therefore resin downward effluent in the way of pole insertion hole 13 is walked around in left and right moves, and converges in the bottom of installation portion 11.Showing weld bond 54 with wave molding in Fig. 8, even if producing weld bond 54 like this, its generating unit is also at the bottom of installation portion 11.
After injection moulding, die sinking and the semi-finished product of the lead-frame 3 as formed products are taken out.Fig. 7 (b) shows the semi-finished product of the lead-frame 3 after taking-up, the semi-finished product of the lead-frame 3 after just shaping do not form ring pilot hole 10, it addition, remain technique projection 53 yet.In the present embodiment, being formed with technique projection 53, therefore the rear end of this technique projection 53 becomes gate vestiges.Then, the semi-finished product of lead-frame 3 are carried out the hole machined of ring pilot hole 10 as post-treatment, remove technique protruding 53 the most in the lump and complete to be formed with as shown in Figure 6 the lead-frame 3 of the final form of ring pilot hole 10.Afterwards, guided rings 2 is assemblied in lead-frame 3.
In the fishline guiding piece of the lead-frame 3 having as above, by injection moulding, lead-frame 3 is formed, and be made up of a component, therefore can easily manufacture compared with the structure that the frame the two component of metallic plate is constituted by cylindrical body with lead-frame 3 as in the past.And, additionally it is possible to readily insure that the parts precision of lead-frame 3, particularly, additionally it is possible to form the angle of inclination that frame main part 12 forward side tilts accurately.Therefore it is also easy to guarantee intensity it addition, lead-frame 3 formed, particularly, uses the synthetic resin being mixed into chopped fiber, therefore, it is possible to readily insure that bigger intensity.Being additionally, since is chopped fiber, even the trickleest shape also is able to easily and highly accurately be formed.Particularly, can the frame main part 12 of installation portion 11 and tabular of easy tubular formed integrally, even additionally image side portion reinforced wall portion 17, alleviate and also be able to be readily formed with trickle concaveconvex shape as recess 16, thinning part 14, as a result of which it is, the position needed sufficiently can be strengthened and realized lightweight.
It addition, arrange cast gate 52 in the part forming ring pilot hole 10, and to carry out hole machined after injection moulding to form ring pilot hole 10 in the way of gate vestiges being removed together with technique projection 53, thus gate vestiges will not be remained in lead-frame 3 in the completed.Therefore, the situation that fishline is wrapped in gate vestiges will not occur.Even if it addition, ring pilot hole 10 tilts, it is also possible to be readily formed by post-treatment, it is possible to make the structure of mould 50,51 simplify.Additionally, the radius of curvature of the curved surface 12e between the upper surface 12c and rear surface 12b of frame main part 12 radius of curvature than the curved surface 12d between the upper surface 12c of frame main part 12 and front surface 12a is little, the structure that therefore even frame main part 12 is plate-shaped and forward side is toppled over, without the curved surface 12e of rear side is carried out undercutting, it is possible to make the lead-frame 3 easily demoulding.
Even if in addition, it is assumed that create weld bond 54, its generating unit also is located at installation portion 11, the periphery of ring pilot hole 10, particularly, does not produce weld bond 54 in the upper end of frame main part 12.It is thus possible to enough prevent the intensity caused because of the generation of weld bond 54 from reducing.In the case of installation portion 11 is tubular and frame main part 12 is tabular, the intensity of installation portion 11 can be readily insured that, on the other hand, the intensity of frame main part 12 is easily little than the intensity of installation portion 11, but on frame main part 12, do not produce weld bond 54, even if the most frame main part 12 is not arranged blocked up also being able to readily insures that intensity.Additionally, the upper end of frame main part 12 is the peripheral part of ring pilot hole 10, and be to be applied with the position of stress because stone guided rings 2 is pressed into ring pilot hole 10, additionally, the most in use act on via guided rings 2 from fishline and have the position of bigger power, but do not produce weld bond 54 in the upper end of frame main part 12, therefore without thickening frame main part 12, it is possible to make lead-frame 3 lightweight.
