本発明は表面に高低差のあるエンボス模様と複
雑な凹凸形状を有する表皮材の成形法に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical field to which the invention pertains] The present invention relates to a method for molding a skin material having an embossed pattern with height differences and a complicated uneven shape on the surface.

Automotive instrument pads are a typical product that consists of a skin with an embossed pattern with different heights on the surface and a cushion material such as foam.

ートを加熱軟化させ、エンボス模様を刻設しため
す型を使つて真空成形し、成形と同時に型表面の
エンボス模様を転写する方法である。 As a conventional method for forming such a skin, there is a female vacuum forming method. This method involves heating and softening a thermoplastic sheet with a smooth surface, vacuum forming it using a test mold with an embossed pattern, and simultaneously transferring the embossed pattern on the surface of the mold.
しかしこの方法では形状の成形と模様の成形が
同時であるため表面に高低差のあるエンボス模様
を転写させる場合には普通の真空成形法よりシー
トの加熱温度を高くする必要がある。 However, in this method, the shape and pattern are formed at the same time, so if an embossed pattern with different heights is to be transferred to the surface, it is necessary to heat the sheet at a higher temperature than in a normal vacuum forming method.
しかしシートの加熱温度が高すぎると成形時に
シートが局部的に薄肉になり、低すぎると逆に模
様の転写性が不充分となる相反する現象が発生し
製品の歩留りが悪いといつた問題があつた。 However, if the heating temperature of the sheet is too high, the sheet will become locally thin during molding, and if it is too low, the pattern transferability will be insufficient, which is a contradictory phenomenon, resulting in poor product yield. It was hot.
本発明はかゝる状況に鑑みなされたものであつ
て高低差のあるエンボス模様の再現性にすぐれた
表皮材の成形法を提供せんとするものである。
The present invention was made in view of the above situation, and it is an object of the present invention to provide a method for molding a skin material with excellent reproducibility of an embossed pattern with differences in height.

According to the present invention, the present invention provides a method for manufacturing a vacuum-formed skin for an automobile instrument pad, which has an embossed pattern with different heights on its surface. This is achieved by vacuum forming the skin sheet and then further heating the sheet while vacuum suction is applied.

目４は表われない。 The present invention will be described below with reference to drawings showing embodiments. Figure 1 shows a cross section of the main part of an instrument pad, and the surface of the skin 1 has a shallow leather grain pattern 2 and a large height difference. It has a stitch pattern 3, and the stitches also show the twist 4 of the thread. To make this skin 1, first, a female drawing vacuum forming mold 5 as shown in FIG. 2 is used.
The surface of this vacuum mold has contradictory patterns 2', 3', and 4' of unevenness on the skin 1, and small vacuum suction holes 6 are opened in the surface of the mold. First, the sheet 7 with a smooth surface is heated to the normal vacuum forming temperature and vacuum formed (Figure 3).
However, since the temperature of the sheet is low, about 2 leather grains are transferred, but the thread twist 4 of the stitch 3 is not visible.

もよい。 Next, while the vacuum is being applied, the sheet containing the stitches 3 is heated from the back side of the skin 1 to near its melting point, as shown in FIG. At this time, twist 4 of the thread is transferred.
The vacuum forming mold 5 used at this time preferably has a porous structure throughout. The sheet heating temperature during molding is determined appropriately depending on the material and thickness of the sheet, but for sheets with a thickness of 0.5 to 1.0 t made of ABS resin modified polyvinyl chloride, a temperature of approximately 140 to 180 degrees Celsius is recommended.
The sheet reheating temperature in the next process is 200-230℃
This reheating method may be any method such as blowing hot air with a hot jet gun or instantaneously heating with a flame such as a burner.
