Description

この発明は、自動車の車体側部に設けられたサイドシルに車体前後方向に延びるように取り付けられ、該サイドシルの側部を覆う樹脂製のサイドシルプロテクタの改良に関し、特に成形時のヒケ対策に関するものである。 The present invention relates to an improvement in a resin side sill protector that is attached to a side sill provided on a side part of a vehicle body so as to extend in the longitudinal direction of the vehicle body and covers the side part of the side sill, and particularly relates to measures against sink marks at the time of molding. is there.

一般に、上述の如きサイドシルプロテクタは、例えば特許文献１に開示されているように、略垂直方向に広がる側壁部と、該側壁部下端縁に一体に連続して略水平方向に広がる底壁部とを備え、自動車の車体側部に設けられたサイドシルに車体前後方向に延びるように取り付けられた状態で、上記サイドシルとの間に空間部が形成されている。 In general, the side sill protector as described above includes, for example, a side wall portion that extends in a substantially vertical direction and a bottom wall portion that extends in a substantially horizontal direction integrally with the lower end edge of the side wall portion as disclosed in Patent Document 1. And a space portion is formed between the side sill and the side sill provided on the side of the vehicle body so as to extend in the longitudinal direction of the vehicle body.

その取付け構造は、上記特許文献１では、サイドシルプロテクタの側壁部裏面に取付部の上下両端を一体に連結して、該取付部を側壁部裏面に該側壁部裏面から距離を隔てるように一体に突設し、サイドシル側のブラケットに形成された支持部を上記取付部に係合させることで、サイドシルプロテクタをサイドシルに取り付けている。
特開２００５−３１３８６０号公報（第５頁、第６頁、図２〜図５） In the above-mentioned Patent Document 1, the mounting structure is such that the upper and lower ends of the mounting portion are integrally connected to the back surface of the side wall portion of the side sill protector, and the mounting portion is integrated with the back surface of the side wall portion so as to be separated from the back surface of the side wall portion.

JP-A-2005-313860 (5th page, 6th page, FIGS. 2 to 5)

しかし、上記特許文献１では、取付部の上下両端に対応するサイドシルプロテクタの板厚がその周りの板厚よりも厚くなっているため、上記取付部の上下両端に対応するサイドシルプロテクタの表面に成形時における樹脂固化速度の遅速によりヒケが発生し、サイドシルプロテクタの外観見栄えが悪くなる。 However, in Patent Document 1, since the plate thickness of the side sill protector corresponding to the upper and lower ends of the attachment portion is thicker than the thickness of the surrounding portion, it is formed on the surface of the side sill protector corresponding to the upper and lower ends of the attachment portion. Sinking occurs due to the slow resin solidification rate, and the appearance of the side sill protector deteriorates.

さらに、上記特許文献１では、取付部の上下両端が側壁部裏面に一体に連結されて、両者間に車体前後方向に開放された閉断面形状の空洞が形成されているため、サイドシルプロテクタを成形した後に脱型する際、上記取付座がアンダーカット部となってこのままでは脱型できず、上記空洞対応箇所にスライド型を配置することになり、成形型の型構造が複雑になる。 Further, in Patent Document 1, the upper and lower ends of the attachment portion are integrally connected to the back surface of the side wall portion, and a cavity with a closed cross-sectional shape opened in the longitudinal direction of the vehicle body is formed between the two. Then, when removing the mold, the mounting seat becomes an undercut portion, and the mold cannot be removed as it is, and a slide mold is disposed at the cavity-corresponding portion, which complicates the mold structure of the mold.

また、上記空洞の断面積を小さくしようとすると、これに伴ってスライド型の厚みも薄くする必要があるが、使用に耐え得るスライド型の厚みには限界があるため、上記空洞の断面積を小さくするにも自ずと限界がある。したがって、サイドシルプロテクタをサイドシルに接近させて両者間の空間部を小さくするのに限界があり、サイドシルからの突出量が少なくて車幅方向の厚みが薄いサイドシルプロテクタを得ることができない。 In addition, if the cross-sectional area of the cavity is to be reduced, the thickness of the slide mold needs to be reduced accordingly.However, since there is a limit to the thickness of the slide mold that can withstand use, the cross-sectional area of the cavity is reduced. There is a limit to make it smaller. Therefore, there is a limit in reducing the space between the side sill protector and the side sill protector, and it is impossible to obtain a side sill protector with a small amount of protrusion from the side sill and a small thickness in the vehicle width direction.

この発明はかかる点に鑑みてなされたものであり、その目的とするところは、外観表面にヒケが生じず、しかも車幅方向の厚みが薄いサイドシルプロテクタを型構造が簡素な成形型で成形できるようにすることである。 The present invention has been made in view of the above points, and an object of the present invention is to form a side sill protector having a thin thickness in the vehicle width direction with a molding die having a simple mold structure without causing any sink marks on the outer surface.
