る内部応力が生ずる。 Now, when insert-molding a metal part, for example, a metal screw member as mentioned above, into a plastic molded product, for example, a ferrous metal is plated, or brass or the like is used as the metal. Disadvantages of this method include thermal stress due to the difference in linear expansion coefficient between the metal insert and the plastic being molded, and furthermore, when the resin solidifies from a molten state, the difference in heat conduction causes problems between the insert periphery and the main body. Internal stresses arise due to differences in cooling rates.
この内部応力を有するプラスチツク成形品は第
６図示の如く時間の経過によつて、更に温度の高
低の繰返しの影響を受けてインサートを包むボス
部に割れ、亀裂等が発生する。 As shown in FIG. 6, the plastic molded product having this internal stress is further affected by repeated temperature fluctuations over time, causing cracks and cracks to occur in the boss surrounding the insert.
一般的に割れ又は亀裂の発生し易い合成樹脂材

ABS、スチロール、アクリル等がある。結晶性
樹脂、例えばナイロン、ポリアセタール、PP、

裂の発生は少ない。 Synthetic resin materials that are generally prone to cracking or cracking include amorphous resin polycarbonate,
There are ABS, styrene, acrylic, etc. Crystalline resins such as nylon, polyacetal, PP,
In the case of PE, etc., cracks and cracks occur less often than in non-crystalline resins.

図示の例では金属ねじとしたが他の金属部材の場
合も同様である。 However, in the case of the appearance-oriented parts shown in FIG. 4, amorphous resins are often used because they are excellent in terms of appearance, rigidity, dimensional accuracy, etc. Further, the shrinkage rate of the crystalline resin is 18/1000 to 22/1000, while that of the amorphous resin is 4/1000 to 6/1000. Incidentally, crystalline resins have many drawbacks such as shrinkage during molding, and the cost is about twice as high. For this reason, the appearance-oriented parts shown in Fig. 4,
Amorphous resin is suitable for the main body of both the mechanical parts shown in FIG. Note that although a metal screw is used as the metal insert in the illustrated example, the same applies to other metal members.
本発明の目的は、上述の欠点をなくし、金属製

成形の際に生ずる応力のない高強度の合成樹脂又

供することにある。 The purpose of the present invention is to eliminate the above-mentioned drawbacks, to eliminate the use of metal parts connecting members, and to reinforce the metal interface with high-strength synthetic resin or reinforcing members that do not cause stress during molding. An object of the present invention is to provide a plastic molded product into which a synthetic resin component connecting member is inserted.
すなわち、上述の目的を達するための本発明に
よる高強度の部品連結用部材をインサートしたプ
ラスチツク成形品は、上記高強度の部品連結用部
材を非金属高強度材料製とする。 That is, in the plastic molded product into which a high-strength component connecting member is inserted according to the present invention to achieve the above-mentioned object, the high-strength component connecting member is made of a non-metallic high-strength material.
また、上記の高強度の部品連結用部材は単体又
は補強材入りの合成樹脂製とするのが好適であ

要がない。割れを生じないため、既知のボスより
も小さな寸法で十分であり、例えばねじ部品の場
合に締付けトルクのみに耐えれば十分である。 According to the present invention, by not using a metal component connecting member, there is no metal interface, and therefore stress that may cause cracking or the like does not occur.
Since the component connecting member has almost the same dimensions as the metal member, there is no need to increase the size of the boss of the plastic molded product. In order to avoid cracking, smaller dimensions than known bosses are sufficient, for example in the case of threaded parts it is sufficient to withstand only the tightening torque.

FIG. 7 shows an internally threaded member 22, FIG. 8 shows a completely embedded internally threaded member 23, and FIG. 9 shows an externally threaded member 24. Each member 22, 23,
There is an annular groove 2 on the outer peripheral surface of one end of 24 to prevent it from coming off.
5 and a rotation stopper 26 in the form of serrations. In addition, although the retaining groove 25 of each member is a square groove in the illustrated example, it may be a semicircular groove, and does not need to be the entire circumference, and may be a convex portion.
The detent 26 may also be polygonal and does not need to have a full circumference.

The component connecting member 32 shown in the figure is a shaft member, and the component connecting member 33 shown in FIG. 12 is a stopper member having a plate-like main portion and a circular cross section in a portion having a stepped portion 34. Since torque acts on the parts connecting members 31 and 32 shown in FIGS. 10 and 11, they require grooves 25 for preventing slippage and serrations 26 for preventing rotation. Torque does not act on the component connecting member 33 shown in FIG. 12, and it is sufficient to prevent it from coming off by the stepped portion 34.

As the molding materials of 31, 32, and 33, high-strength synthetic resin such as strong nylon can be used alone, and reinforced synthetic resin materials reinforced with reinforcing materials such as glass fiber or carbon fiber can be used. Molded in one piece depending on the material. Furthermore, it is also possible to select and use synthetic resin-impregnated compression molded materials having the required strength. Through experiments, we have found that it is sufficiently practical to use reinforced synthetic resins for both crystalline and amorphous synthetic resins.
