この発明は各部材間が特別の固定具なしに一体化された

にしたものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing an instrument panel in which each member is integrated without special fixing devices and in which pad material is partially formed. This makes it possible to obtain a high-quality instrument panel.
従来この種のクラッシュパッドをインストルメントパネ

該キャビティ内へ半硬質ウレタンフオームを注入するこ
とによって一体成形していた。Conventionally, when installing this type of crash pad on an instrument panel, a semi-rigid urethane foam pad material with a PVC skin separately molded on a frame material made of sheet metal, acrylic-styrene graft copolymer, ABS resin, etc. was used. A cavity is formed by attaching or preforming a PVC skin and a frame material using a vacuum forming method,
It was integrally molded by injecting semi-rigid urethane foam into the cavity.

ならず、やはり工程数や部品数が増えるという欠点を免
れなかった。However, the former method has the disadvantage that it must be mechanically attached using bolts or nuts, which requires a separate process, and the latter method requires a folded surface material to be formed at the end of the frame when forming a full-surface pad. However, when forming a partial pad, it is necessary to install a blind to treat the ends of the epidermis, which inevitably increases the number of steps and parts.

ルメントパネルの製造方法である。The method of manufacturing an instrument panel partially formed with padding material according to the present invention eliminates the above-mentioned drawbacks of the conventional example, and is characterized in that a step is provided at the periphery of the area where padding is required, and the instrument panel other than the padding area is A frame material whose parts have been subjected to mold release treatment and a skin material which has been previously formed into a predetermined shape are placed in a mold with a cavity formed so as to close it leaving only the part that requires padding. This method of manufacturing an instrument panel with a partial pad is characterized by injecting and foaming urethane foam into a cavity formed between the frame material and the skin material.

くはシートとしてはシボ付き塩ビフィルム等が好ましく

表的である。In the present invention, the plastic film or sheet serving as the skin material is preferably a textured vinyl chloride film, and the frame material that has adhesive properties therewith is typically the acrylic-styrene graft copolymer or ABS resin.

成形時に施した外部離型剤を、パッド部分に相当する以
外の箇所を残し、付着した離型剤を拭き取るか、別途所
定箇所に外部離型剤を塗布する等の手段がある。In addition, as for the mold release treatment applied to the frame material, the external mold release agent applied during molding of the frame material is left in areas other than the pad area and the adhering mold release agent is wiped off, or the external mold release agent applied to the frame material is wiped off in designated areas. There are methods such as applying a molding agent.
以下本発明の一実施例を図面を用いて説明する。An embodiment of the present invention will be described below with reference to the drawings.

れたキャビティにウレタンフオーム５を注入発泡したと
ころを示すものである。In FIG. 1, a skin material 1 preformed into the external shape of a partial pad by vacuum forming is set on a lower mold 2, and a step 10 is provided on the peripheral edge of the portion where a pad is required from above, and the mold is released. A treated ABS resin frame material 3 is placed and fixed with an upper mold 4, and urethane foam 5 is injected and foamed into the cavity formed by the skin material 1 and this frame material 3.
このとき接着性を有するＡＢＳ樹脂製フレーム材と表皮
材とは、段差部分１０で離型剤を介して接触している。At this time, the ABS resin frame material having adhesive properties and the skin material are in contact with each other at the stepped portion 10 via a mold release agent.
７はその接触面である。次に第２図に示したように、部

ーム材３から剥離する。7 is its contact surface. Next, as shown in FIG. 2, the frame material on which the padding material has been partially formed is taken out of the mold and the unnecessary part of the skin material is cut out along the step 10 with the cutter 8. It is easily peeled off from the frame material 3.
なおフレーム材の、パッド端部に対応する位置に、予め
多数の小孔を穿っておくと、ウレタンフオーム５の注入

るアンカー９となる。Note that if a large number of small holes are drilled in advance in the frame material at positions corresponding to the pad ends, the injected urethane foam will protrude from the back side of the frame material when the urethane foam 5 is injected, and the pad material will become attached to the frame material. This results in an anchor 9 that is firmly fixed.
