意匠性を高めた自動車用内装部品に関する。[Detailed Description of the Invention] (Field of the Invention) This invention relates to an automobile interior part in which a thickening mold pad is installed between a core material and a skin material, and in particular to an automobile interior part with enhanced appearance design. Regarding parts.
（従来技術とその問題点）
自動車用内装部品の代表的なものに自動車用ドアトリム
がある。(Prior art and its problems) Automotive door trims are typical automotive interior parts.
通常、第５図に示すように、自動車用ドアトリム１は、

層を裏打ちしてソフト感を得るようにしている。Usually, as shown in FIG. 5, the automobile door trim 1 is
In order to obtain a desired product shape, it is generally composed of a core material 2 formed into a curved shape and a skin material 3 that is attached to the surface of the core material 2 to provide decorative properties. The core material 2 has appropriate rigidity and shape retention, and the skin material 3 provides a decorative surface for the product and, if desired, is lined with a foam layer to provide a soft feel.
ざらに、例えばドアトリム１のアームレスト部のように
比較的大きなりッション性を必要とする部位には、増厚

る。In general, thickening mold pads 4 are installed in areas that require relatively large cushioning properties, such as the armrest portion of the door trim 1, to satisfy functionality.
第６図は上記自動車用ドアトリム１の製造工程を簡略的
に示すもので、コールドプレス用下型５の型面５ａ上に
芯材２の素材である熱可塑性複合樹脂板を加熱軟化させ
て載置する。FIG. 6 schematically shows the manufacturing process of the above automobile door trim 1, in which a thermoplastic composite resin plate, which is the material of the core material 2, is heated and softened and placed on the mold surface 5a of the lower mold 5 for cold press. place
そして、その上側から所定箇所に増厚用モールドパッド

すると同時に、芯材２と表皮材３とを一体貼着させて、
ドアトリム１の成形を完了する。After positioning the thickening mold pad 4 at a predetermined location from above, the skin material 3 is set from above. Thereafter, the upper mold 6 for cold press is lowered relative to the lower mold 5 for cold press, and the upper and lower molds 5 and 6 for cold press are clamped to form the core material 2 into a desired curved shape. 2 and the skin material 3 are integrally attached,
The molding of door trim 1 is completed.
なお、増厚用モールドパッド４の底面には図中符号７で
示す補強板が固着されている。Note that a reinforcing plate indicated by reference numeral 7 in the figure is fixed to the bottom surface of the thickening mold pad 4.

が芯材内に埋設固定されていることを特徴とする。(Structure and Effects of the Invention) In order to achieve the above object, the present invention provides a core material formed into a desired curved shape and having thickening mold pads attached at appropriate locations, and a core material formed on the surface side of the core material. In an automobile interior part composed of a covering skin material, the thickening mold pad has a porous support member such as a wire mesh or metal lath fixed to the outer peripheral surface in contact with the core material, and the support member A flange that is flush with the mold pad surface is formed at the end edge of the mold pad, and this flange is embedded and fixed within the core material.

場合において、従来のように両者の見切りラインに沿っ
て細溝が形成されることなく、増厚用モールドパッド部
分の見栄えが著しく向上する利点がある。That is, according to the above configuration, a porous support member is fixed to the outer peripheral surface of the mold pad for increasing the thickness, and the flange formed by bending the end edge of the support member is in contact with the mold pad surface. This flange is set to be buried inside the core material, so when the surface of the core material and the thickening mold pad are covered with a skin material, it is not possible to follow the parting line between the two as in the past. This has the advantage that the appearance of the thickening mold pad portion is significantly improved without the formation of narrow grooves.

きる利点がある。Support members used in the present invention include wire mesh,
Using porous material such as metal lath, the edges are approximately 90mm thick.
Since it is equipped with a flange bent at an angle of 100 degrees, when positioning the thickening mold pad with respect to the core material, the support member digs into the core material, so it can be securely positioned and fixed, and after molding, Since the support member and the core material are firmly joined by the anchor effect, there is an advantage that the mold pad can be easily and reliably attached to the core material.
（実施例の説明）
以下、本発明を自動車用ドアトリムに適用した実施例に
ついて添付図面を参照しながら詳細に説明する。(Description of Examples) Hereinafter, examples in which the present invention is applied to an automobile door trim will be described in detail with reference to the accompanying drawings.

構成されている。In FIG. 1, an automobile door trim 10 has an armrest portion and a door waist portion bulging toward the interior of the vehicle,
A core material 11 molded to have a desired curved shape;
A thickening mold pad 12 made of polyurethane foam or the like is attached to the core material 11 to provide cushioning properties to the armrest portion, and a skin material 13 covers the outer surfaces of the core material 11 and the thickening mold pad 12. It consists of
ざらに上記増厚用モールドパッド１２は、第１図ならび

ールドパッド１２の外表面とこのフランジ１５面とが面
一になるように設定されている。As shown in FIGS. 1 and 2, the thickening mold pad 12 has a porous support member 14 such as a wire mesh or metal lath formed in advance during molding along the outer peripheral surface that contacts the core material 11. The support member 14 is bent outward by 90' at its end edge to form a flange 15 along the outer periphery, and is connected to the outer surface of the thickening mold pad 12. It is set so that it is flush with the flange 15 surface.

り、アームレスト部の美観が著しく向上する。Therefore, during press molding of the core material 11, this mold pad 12 can be firmly attached to the core material 11 due to the anchoring effect of the support member 14. When the recesses formed between the thickening mold pad 12 and the core material 11 are removed and the skin material 13 is used to cover them, the thin grooves along the parting line between the two are not formed and the product surface is smooth. This significantly improves the appearance of the armrest.
なお、この実施例では芯材１１として、成形性。In this example, the core material 11 is moldable.

The skin material 13 is extruded into a sheet shape using a die extruder, then heated and softened, and then molded into the curved shape shown in FIG. 1 by cold press molding. It uses a foamed PVC sheet that has a structure that has a good feel, and the cells get larger as they go deeper into the interior, providing appropriate cushioning properties.
次に、第３図、第４図に基づき同自動車用ドアトリム１
０の製造工程について説明する。Next, based on FIG. 3 and FIG. 4, the door trim 1 for the same automobile is
The manufacturing process of 0 will be explained.

をセットする。First, as shown in FIG.
The heated and softened core material 11 is placed on the mold surface 16a, and the thickening mold pad 1 is roughly placed on the armrest portion.
2 is positioned and fixed, and then the skin material 13 is placed from above.
Set.
なお、芯材１１の表皮材１３対向側面には、ホットメル

化が行なわれる。Next, the upper mold 19 for cold press, which is located above the lower mold 16 for cold press and is configured to be able to be raised and lowered by the hydraulic cylinder 18, is lowered, and the upper and lower molds 16 and 19 for cold press are used to create a predetermined gap between the molds. Core material 11 with clearance
The core material 11 and the skin material 13 are formed into a desired curved shape, and the core material 11 and the skin material 13 are integrated with a thickening mold pad 12 interposed therebetween.
このとき、前述したようにサポート部材１４の多孔内に

部材１４により、モールドパッド１２は変形することが
なく、確実かつ精度良く芯材１１に固定される。At this time, as described above, due to the so-called anchor effect in which the core material 11 digs into the pores of the support member 14, the thickening mold pad 12 is firmly bonded to the core material 11, even when a large press pressure is applied. Since a support member 14 is integrally fixed to the outer circumferential surface of the thickening mold pad 12 that contacts the core material 11, the support member 14 prevents the mold pad 12 from being deformed and ensures reliability and precision. It is well fixed to the core material 11.
