【実施例】以下、本発明の実施例を図面に沿って詳細に
説明する。Embodiments of the present invention will now be described in detail with reference to the drawings.
【０００９】本発明方法によって製造されるドアトリム
は、基材の表面に表皮材が装着されてなり、取付部品例
えばスピ−カグリルが装着されてなる。The door trim manufactured by the method of the present invention comprises a base material having a skin material attached to the surface thereof, and an attachment component such as a speaker grill attached thereto.
【００１０】その製造方法について、具体的に説明す
る。The manufacturing method will be specifically described.
【００１１】まず、図１に示すように、スピ−カグリル
１（例えばポリプロピレン製）の周縁部を環状の支持部
２によって支持した上型３と、上記支持部２に対応して
押圧凸部４が形成された下型５との間に、ドアトリム６
を構成する表皮材７を配置する。First, as shown in FIG. 1, an upper die 3 which supports a peripheral portion of a speaker grill 1 (made of polypropylene, for example) by an annular supporting portion 2 and a pressing convex portion 4 corresponding to the supporting portion 2. The door trim 6 is provided between the lower mold 5 and
The skin material 7 constituting the above is arranged.
【００１２】スピ−カグリル１は、基部１ａの周縁より
該基部１ａに対して略鉛直方向に延びる周縁部１ｂと、
基部１ａより立設され周縁部１ｂより長さの長い取付ボ
ス部１ｃとを有する。The speaker grill 1 has a peripheral edge portion 1b extending from the peripheral edge of the base portion 1a in a substantially vertical direction with respect to the base portion 1a.
It has a mounting boss portion 1c which is erected from the base portion 1a and is longer than the peripheral edge portion 1b.
【００１３】押圧凸部４は、先端周縁が、表皮材７をス
ピ−カグリル１に対応した円形状に切断する切刃４ａと
なっている。The pressing convex portion 4 has a cutting edge 4a having a tip peripheral edge for cutting the skin material 7 into a circular shape corresponding to the speaker grill 1.
【００１４】そして、下型５の上に基材８となる溶融状

の一部７ａをスピ−カグリル１に対応して円形状に切断
する。また、押圧凸部４によって、溶融した樹脂（基材
８）の流れが止められる。Then, after the molten resin serving as the base material 8 is filled on the lower mold 5, the upper mold 3 is lowered to mold the door trim 6. At that time, when the upper mold 3 is lowered, the skin material 7 is pulled downward by the speaker grill 1, while it is pulled upward by the pressing convex portion 4, and a large tension acts on the skin material 7. The boss portion 1c penetrates through the skin material 7, and then the cutting edge 4a is used to cut the skin material 7
A part 7a of the above is cut into a circular shape corresponding to the speaker grill 1. Moreover, the flow of the molten resin (base material 8) is stopped by the pressing convex portion 4.
【００１５】そして、スピ−カグリル１の表面が、表皮

通した取付ボス部１ｃは樹脂の固化によりドアドリム８
（基材８）に固着される。The surface of the speaker grill 1 is pressed so that it is substantially flush with the surface of the skin material 7, and the mounting boss portion 1c penetrating the skin material 7 is solidified by the resin so that the door rim 8 is pressed.
It is fixed to the (base material 8).

ピ−カグリル１の周縁の見栄えがよくなる。At this time, the supporting portion 2 and the skin material 7 and the spine
It is located between the peripheral portion 1b of the crawl 1 and the skin material 7 is in a compressed state. Therefore, when the upper die 3 is lifted after the molding is completed, the skin material 7 is restored and the spine is spun.
Since the gap between the grille 1 and the peripheral portion 1b is filled, the appearance of the peripheral edge of the speaker grill 1 is improved.
