この発明は、装飾性の優れた自動車用ドアトリム等の内
装部品を、簡易に製作できるようにした内装部品の製造
方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of the Invention) The present invention relates to a method for manufacturing interior parts, which makes it possible to easily manufacture interior parts such as automobile door trims with excellent decorative properties.
（従来技術とその問題点）
例えば、自動車用ドアトリム等の内装部品は、車体パネ

フオーム等のパッド材を介して表皮材を被覆して構成す
るのが一般的でおる。(Prior art and its problems) For example, interior parts such as automobile door trims are made by covering the surface of a core material molded to approximately match the shape of the vehicle body panel with a skin material through a pad material such as urethane foam. It is common to configure
そして、最近では製品外観を向上させるために、上記表
皮材として、ＰＶＣシートとクロス材、ＰＶＣシートと
カーペット等のように異なる材質のものを組合せた複合
表皮材を使用して、意匠性の向上を図るようにしたもの
がある。Recently, in order to improve the appearance of the product, composite skin materials that combine different materials such as PVC sheet and cloth material, PVC sheet and carpet, etc. are used as the skin material to improve the design. There is something designed to do this.
このように、異種材料の表皮材を用いた場合、両者の接
合には、ミシン縫いによる方法、あるいは高周波、溶着
等の方法がとられるが、多大な工数を必要とする難がお
る。In this way, when skin materials made of different materials are used, methods such as machine stitching, high frequency welding, and welding are used to join the two, but these methods require a large number of man-hours.
この点、最近では実開昭６０−３４４３７号公報に示さ

れ程簡略化されるものとはいえなかった。Although the process is simpler than the high-frequency welding method, two steps are required since the skin material is usually attached to the core material and then painted in the next step, so the workability is much simpler. It could not be said that it was something that would be done.

われず、製品外観上の好ましいものではなかった。In addition, since the paint is applied to the surface of the skin material, it has been pointed out that the surface texture and feel of the painted surface may be impaired.Also, when applying the paint, masking jigs, etc. are usually used to remove the border between the two. (hereinafter referred to as a parting line), however, due to leakage from the end of the masking or unevenness in paint particles, this parting line was not clearly visible, which was not desirable in terms of product appearance.

からな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 shape, a parting line attached to the surface of the core material, and a parting line having an external appearance such as color or pattern. In a method for manufacturing an automobile interior part made of skin materials made of different materials, a predetermined parting line formed on the skin material bonded and molded on the surface of the core material is cut off before molding. , a process of plotting a parting line at the time of development on the skin material in a sheet state, and setting a parting line at the time of development in advance on the skin material, and a process of different colors,
It is characterized by comprising the following steps: a step of printing a pattern, etc., and a step of heating and softening the printed skin material and then adhering it to the surface of a preformed core material by vacuum or press molding. shall be.
すなわち、前記構成によれば、芯材の形状に沿って３次

着一体化すれば簡易、かつ廉価に表面外観を相違させた
表皮材仕様の内装部品が製造でき、作業性が大幅に簡略
化される利点がおる。That is, according to the above configuration, the parting line provided on the skin material formed in a three-dimensional shape along the shape of the core material is plotted in a developed shape, and the parting line provided on the skin material in a sheet state before molding is plotted in advance when developed. Since the separation line of the material is set as a border, if the surface material is printed with different appearances such as colors and patterns at the separation line at the time of development, this printed surface material can be used as a core material. If it is integrated with the surface of the material, it is possible to easily and inexpensively manufacture interior parts with skin material specifications that have different surface appearances, which has the advantage of greatly simplifying workability.
さらに、予め表皮材に展開時の見切りラインを境にして

次に第２図ないし第６図に基づき上記自動車用ドアトリ
ム１の製造方法について説明する。Next, a method for manufacturing the above automobile door trim 1 will be explained based on FIGS. 2 to 6.
本発明方法は以下の工程に大別される。The method of the present invention is roughly divided into the following steps.
（１）表皮材に展開時の見切りラインを設定する工程。(1) The process of setting a parting line for the skin material when it is developed.
（２）展開時の見切りラインに沿って表皮材にプリント
加工を施す工程。(2) A process of printing on the skin material along the parting line during development.
（３）プリント加工を施された表皮材を芯材に貼着一体
化する工程。(3) The process of bonding and integrating the printed skin material to the core material.
（１）展開時の見切りライン設定工程 まず、第２図に示すように表皮材３と同一材質。(1) Separation line setting process during development First, as shown in FIG. 2, it is made of the same material as the skin material 3.
同一厚みに設定された表皮材３のモデル９に１０ｍｍ間
隔の格子状ライン１０を形成する。Grid-like lines 10 are formed at 10 mm intervals on a model 9 of the skin material 3 set to the same thickness.
そしてこのモデル９を加熱軟化させた後、所要形状に予

皮材モデル９の表面に所定の見切りライン６を線引きす
る（第３図参照）。After this model 9 is heated and softened, a seal is integrally pasted on the surface of the core material 2 that has been preformed into a desired shape, and a predetermined parting line 6 is drawn on the surface of the skin material model 9 (Fig. 3). reference).
そして第３図に示す３次元形状に描いた見切りライン６
を、成形前のシート状態におる表皮材に展開時の見切り
ライン１１としてモデル９にプロットする（第４図参照
）。Then, the parting line 6 drawn in the three-dimensional shape shown in Fig. 3
is plotted on the model 9 as a parting line 11 at the time of development on the skin material in a sheet state before molding (see FIG. 4).
このとき、表皮材のモデル９は、１０ｍｍ間隔の格子状
ライン１０が縦横に設定されているため、各部位の伸張
の度合が正確に把握でき、展開時の見切りライン１１に
容易に変換することができる。At this time, since the skin material model 9 has lattice-like lines 10 set vertically and horizontally at 10 mm intervals, the degree of elongation of each part can be accurately grasped, and it can be easily converted to parting lines 11 at the time of development. I can do it.
（２）プリント加工工程

良い。(2) Printing process Next, as shown in FIG. 5, the skin material 3 is printed with different patterns, a leather drawing pattern 7 and a striped pattern 8, with the parting line 11 at the time of development as the boundary. By the way, in this case, it is also possible to make the two colors different.
（３）表皮材と芯材との貼着一体化工程第６図において

３が芯材２の表面に沿って忠実に貼着され、両者が一体
化される。Then, the vacuum forming mold 12 is raised by the driving of a lifting means (not shown), and the core material 2 and the skin material 3 are brought into close contact with each other, and the air between them is pumped through the vacuum hole 2a formed in the core material 2.
The skin material 3 is then removed to the outside by a vacuum suction means (not shown) through the vacuum suction hole 12a of the vacuum forming mold 12, and the skin material 3 is adhered faithfully along the surface of the core material 2, thereby integrating the two.
そして、一体化された半製品を真空成形用金型１２から

しても良いことは勿論でおる。Then, the integrated semi-finished product is taken out from the vacuum forming mold 12, and the peripheral end 3a of the skin material 3 is rolled and fixed onto the back side of the core material 2, completing the assembly of the door trim 1 shown in FIG. . Incidentally, although vacuum forming was used in the above embodiment, it goes without saying that the skin material 3 and the core material 2 may be integrated by press forming.

する。As described above, if the method of the present invention is used and the skin material is printed in advance, interior parts such as automobile door trims can be easily manufactured by simply pasting the skin material and the core material, resulting in improved workability. In addition, since the parting line is formed in advance by printing as mentioned above, the parting line that appears on the final product looks much better than when using painting methods, etc., and the appearance design is significantly improved. .
