いられている。 Conventionally, soft sheets or foam sheets are laminated on top of a core material of a predetermined shape obtained by injection molding etc. for cosmetic purposes or to provide cushioning properties as automotive interior parts. Many products are used that are covered with soft leather as a skin material.
そして、このような内装部品は、通常、所定形

にて得られている。 Such interior parts are usually made by placing a predetermined soft leather that has been softened by heating on a core material that has been formed into a predetermined shape via an adhesive, and then attaching the leather to the core material in advance. By suctioning and removing the air interposed between the core material and the soft leather through a vacuum hole, the soft leather is pressed to fit the shape of the core material, and then they are bonded with an adhesive. Obtained by vacuum forming method.

う問題があつた。 Therefore, in such a vacuum forming method in which soft leather is applied to a core material, the vacuum hole for air release is formed in the core material in a post-processing process using an electric drill or the like. Alternatively, a pin or the like provided on a fixed or movable mold for molding the core material is provided at the same time as molding, and air is removed during vacuum molding. However, in the former case, there is a problem that the drill is easily damaged because the diameter of the vacuum hole to be formed is small and thin, and in the latter case, it is difficult to remove the product (core material). Holes that are parallel to the direction are easy to mold, but holes that are perpendicular to the direction cannot be molded without using a slide mechanism, etc., which complicates the mold structure and shortens the mold life. There was a problem.
また、従来の真空穴が設けられた樹脂製芯材を

ないという問題があつた。 In addition, when vacuum forming a conventional resin core material with a vacuum hole and soft leather, the soft leather portion located near the vacuum hole is locally sucked into the vacuum hole. Due to the thickness of soft leather, especially when it is a laminated material, even if it is necessary to create a depression on the product surface or have sharp design lines at the corners of the product recess, There was a problem that it was not possible to produce products that were faithful to the design.
ここにおいて、本発明は、かかる事情に鑑みて

成上の問題を悉く解消し得たのである。 The present invention has been made in view of the above circumstances, and the gist thereof is to form a core material by vacuum forming a soft skin material having a heat-softening layer on the back side. When manufacturing a predetermined automobile interior part by crimping the top of the skin material and bonding them together, a foam layer on the back side of the skin material is placed at the corner of the recess of the core material in the direction of the crimping of the skin material. A vacuum groove into which only the skin material can enter is provided along the corner portion, and the vacuum groove is communicated with an air suction mechanism on the back side of the core material to remove air interposed between the skin material and the core material. Therefore, even if the skin material is a thick laminated material,
It is possible to effectively express the sharp design lines required for the corners of product recesses, prevent the occurrence of depressions on the product surface, and solve all the problems in the conventional vacuum hole formation. It is.

Note that the soft leather 2 is usually heated to a heating temperature close to that at which the drawdown phenomenon occurs. Then, this heated and softened soft leather 2
In contrast, as shown in FIG. 2, the base 7 of the vacuum forming machine is raised using a suitable driving means such as a cylinder. At this time, the vacuum forming mold 3 is placed on the base 7 of the vacuum forming machine, and the core material 1 is set in the vacuum forming mold 3, so that the heated and softened leather 2 is heated and softened. The surface of the core material 1 is covered. Next, the air interposed between the soft leather 2 and the core material 1 (see FIG. 2) is activated by the solenoid valve 8.

のである。 By the way, in the conventional vacuum forming process, a phenomenon occurs in which the corner part G of the product recess curves and rises as shown in FIG. Even if a vacuum hole 1'a was provided in the hole 1'a, this problem could not be solved at all, and it was extremely difficult to form an acute design line.
このため、本発明にあつては、第４図に示され

されることとなる。 Therefore, in FIG. 3, when the solenoid valve 8 is activated and air is evacuated using the vacuum pump 9 through the vacuum hole 7s of the vacuum forming machine base 7 and the vacuum hole 3s provided in the vacuum forming mold 3, the result shown in FIG. Vacuum groove 1s shown in FIG. 5 provided in corner part F of core material 1
Also, the vacuum groove 1 that wraps around the back surface of the core material in Figure 7
s' is simultaneously evacuated (aspirated as shown by the arrow in Figure 7), and at this time heating,
Since the softened soft leather 2 is in a plastic state, it takes on the shape of the core material 1, and at the same time, as shown in FIG.
The back surface of the PVC leather 2b enters into the vacuum groove 1s of the core material 1, and accordingly, for example, a force acts on the soft PVC leather 2a as well to try to enter the vacuum groove 1s. And for this, core material 1
The design line (corner line) of the corner G of the product recess corresponding to the corner F of is sharply expressed. In addition, in this way, the corner part F of the core material 1 recess
The size of the vacuum groove 1s formed in the groove 1s will be appropriately determined depending on the material, structure, thickness, etc. of the soft leather 2 to be adhered. For example, in FIG. If the E dimension indicating the vacuum groove width is 1.0 mm, preferably the C dimension indicating the vacuum groove width is 1.0 mm.
The dimension D, which indicates the depth of the vacuum groove, will also be 1.0 mm.
そして、このようにして軟質レザー２と芯材１

得たのである。 As described above, according to the present invention, a mold for forming a vacuum hole can be used, which in the past would only evacuate the vacuum hole and create a depression on the product surface. In contrast, when placing a pin in the corner of the soft skin material 2, problems such as a shortened mold life occurred, but in order to vent air through the vacuum groove 1s provided at the corner of the core material, Since the same suction force is applied and the back surface of the skin material enters the vacuum groove by the same amount, the sharp design line of the recess can be clearly formed, and the vacuum hole can be There is no longer any denting in the corresponding skin material. In addition, since it is only necessary to form the vacuum groove, there is no need to drive pins into either the fixed mold or the movable mold of the mold for molding the core material, and there is no need to grind them together.
Therefore, effects such as a longer life of the mold could also be achieved.
