なるという不具合が生ずる。However, when the plastic molded article having the standing pieces formed as in the above-mentioned publication is molded from a so-called glass mat thermoplastic in which long glass fibers are mixed in a mat shape, the standing pieces are formed. Since the glass long fibers are also mixed, the glass long fibers hinder the welding, that is, the resin content of the welded portion is reduced by the amount of the mixed glass long fibers, and the welding with the partner component becomes insufficient. The problem described above occurs.

る。As described above, in order to form the tip welding portion 23 with a resin in which the glass long fibers 11, 11,... Are less mixed, data on the flow characteristics of the glass long fibers 11 during molding as shown in FIG. What is necessary is just to determine based on. This data is obtained by modeling a standing piece 15 having a shape as shown in FIG. 5. In FIG. 5, a hatched portion h1 indicated by a solid line indicates that the glass long fibers 11 are densely formed so as to obtain sufficient rigidity. The hatched portion h2 indicated by a broken line indicates that the glass fiber 11 is mixed (the glass long fiber 11 is included by about 40% by weight). h3 is such that the glass long fiber 11 is less mixed (less than 8% by weight) so that sufficient welding strength can be obtained.
1 is included). According to the data of FIG. 4, it can be seen that as the width W of the upright pieces 15 becomes narrower, the glass long fibers 11 become more difficult to move with respect to the upright pieces 15. Therefore, in consideration of the flow characteristics of the long glass fiber 11 at the time of such molding, the width W of the upright piece 15 and the width W of the upright piece 15 are adjusted so that the long glass fiber 11 does not sufficiently reach the distal end welding portion 23 of the upright piece 15. What is necessary is just to set the relationship with the height H. It should be noted that the data shown in FIG. 4 is an example, and the flow shape of the long glass fiber 11 is changed depending on the molding conditions such as the whole shape of the standing piece 15 being changed, the radius of the base 17 being formed, and the mold temperature. The curve retains the above tendency, but is slightly different.

The resin of the tip welding portion 23 can be sufficiently ensured, and the lid outer panel 1 (standing piece 15) can be firmly welded to the lid inner panel 3 without being disturbed by the long glass fiber 11.

9, the front end welding portion 2 of the front end portion 19 is formed.
Long glass fibers 11 is less likely to migrate to 3, the tip weld portion 2
3 can be carried out quite sure that the small resin with long glass fibers 11. Also, the base end side of the standing piece 15 (the base 1
In 7), since the lateral width is wide, the glass long fiber 11 is easily transferred, and the glass long fiber 11 can be transferred to the base 17 without fail to secure the strength and rigidity.

It is a matter of course that the upright pieces 15 with less contamination are formed on both molded products.

樹脂部品と溶着される起立片の先端溶着部を基部に比べ
幅狭に形成しかつ該基部に比べガラス長繊維の混入が少
ない樹脂にて構成したので、溶着部の樹脂分を十分に確
保できて上記樹脂部品との溶着をガラス長繊維に邪魔さ
れずに強固にすることができる。As described above, according to the present invention,
The tip weld of the standing piece that is welded to the resin part is compared to the base.
Since it is formed of a resin having a narrow width and a small amount of glass long fibers compared to the base portion, it is possible to secure a sufficient amount of resin in the welded portion and to prevent the welding with the resin component from being disturbed by the glass long fibers. Can be strong.
