Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method and a mold for molding interior materials, etc. More specifically, the present invention relates to a molding method and a mold for interior materials, etc. More specifically, the present invention relates to a molding method and a mold for interior materials, etc. The present invention relates to a method for molding an interior material, etc., and a mold, which are arranged to form appropriate uneven portions on the interior material, etc. by matching a lower mold and an upper mold.

[Conventional technology]

2. Description of the Related Art Conventionally, there have been methods and molds for press-molding interior materials such as vehicle interior materials, such as floor carpets, to correspond to a desired floor shape. As shown in FIGS. 7 and 8, this mold 1 consists of a lower mold 2 and an upper mold 3. Concave portions 4, 4 are formed on both sides of the lower mold 2, and a floor is formed in the center. Convex portions 5 are formed corresponding to the shape, and convex portions 6, 6 that can fit into the concave portions 4, 4 are provided on both sides of the upper die 3.
A concave portion 7 into which the convex portion 5 of the lower mold 2 can fit is formed in the center. Furthermore, mold matching parts 2a and 3a are formed between the lower mold 2 and the upper mold 3, respectively.

Then, the raw floor carpet 11 is placed between the lower mold 2 and the upper mold 3, and the end portion of the raw floor carpet 11 is placed so as to give an appropriate tension to the raw floor carpet 11. 11a is held by a clamp 13, and in this holding state, the lower mold 2 and the upper mold 3 are brought together to form a floor carpet 12 having uneven parts as an interior material. In addition, the original fabric of the floor carpet 1
1 is formed from a carpet layer 14 on the front side and a backing material 15 on the back side.

[Problem that the invention seeks to solve]

However, when molding the floor carpet 12 as an interior material using the conventional mold 1,
An original fabric 11 of the floor carpet is pressed between the edge 2b of the lower mold 2 on the side of the mold matching part 2a and the outer edge 3b of the tips of the convex parts 6, 6 of the upper mold 3. ,
The original fabric 11 of the floor carpet is placed in the concave portion 4 of the lower mold 2.
There is a risk that the backing material 15 on the back side of the original fabric 11 of the floor carpet may be damaged or scraped off during the molding process, and the sound insulation and shape retention properties of the floor carpet 12 after molding may be reduced. In addition, it has the drawback that the fibers of the carpet layer 14 on the surface side may come off or be damaged, and various troubles are likely to occur, work efficiency may deteriorate, and the cushioning properties and appearance may also deteriorate. It had

An object of the present invention is to improve the efficiency of molding work for interior materials, etc., and to prevent the back side or front side of the interior materials, etc. from being damaged or scraped off during molding, and to make the interior materials suitable for use as interior materials.

For example, it can be applied to various interior materials such as molded ceilings, back garnishes, and door linings. The original fabric 11 of this floor carpet is formed from a carpet layer 14 on the front side and a backing material 15 on the back side, and the backing material 15 is formed from a felt layer etc. formed by mixing thermoplastic resin etc. .

In this embodiment, either the edge 42 of the lower mold 32 on the mold matching part 41 side or the outer edge 43 of the tip of the convex part 36 of the upper mold 33, the lower mold 3
The rotating member 4 is attached to the end edge 42 on the side of the mold matching part 41 of 2.
5 are arranged. This rotating member 45 is activated when the floor carpet original fabric 11 is pressed against the concave portion 34 of the lower mold 32 and the convex portion 36 of the upper mold 33.
In the initial stage of insertion, the lower mold 3 that comes into contact
It is formed in a straight line on the end edge portion 42 of No. 2.

The rotating member 45 is formed of a roller 46 formed along the longitudinal direction of the edge portion 42, as shown in FIGS. It is rotatably supported in a bearing hole 47 formed in the portion 42 . still,
As shown in FIG. 4, both ends 46a of the roller 46
may be pivotally supported via a bearing 48.
Alternatively, the roller 46 may be formed as a rotating shaft, and a coil spring, a rotating ring, or the like may be rotatably fitted around the outer periphery of the roller 46.

FIG. 5 shows a different embodiment of a mold for interior materials, etc. according to the present invention, and parts corresponding to those in the above-mentioned embodiment are given the same reference numerals, and further detailed explanation will be omitted. Although omitted, the cleaning brush 51 of the roller 46 is attached to the edge 42 of the lower mold 32 so that its tip abuts against the roller 46 serving as the rotating member 45, and the cleaning brush 51 of the roller 46 is attached to the edge 42 of the lower mold 32, and the cleaning brush 51 of the roller 46 is attached to the edge 42 of the lower die 32 so that the cleaning brush 51 of the roller 46 contacts the roller 46 as the rotating member 45. It is designed to be able to remove deposits such as dust and the like.

In addition, a discharge port 52 is connected to the lower mold 3 so that the dust and other deposits removed by the cleaning brush 51 do not fall on the molding surface side of the lower mold 32 to the outside of the lower mold 32.
2, an air suction pump is connected to this discharge port 52 via an air pipe (not shown),
It is configured such that deposits such as dust can be discharged from the discharge port 52.

Incidentally, the diameter of the roller 46 of the rotating member 45 is formed to correspond to the curvature of the etch shape of the end edge 42 of the lower mold 32 of the mold 31. Further, in this embodiment, a case has been described in which the rotating member 45 is provided on the edge portion 42 of the lower mold 32, but the rotation member 45 similar to that described above is provided on the outer edge portion 43 of the convex portion 36 of the upper mold 33. A member 45 may also be provided.

Next, an embodiment of the method for molding interior materials and the like according to the present invention will be described.

First, as shown in FIG. 6, an original fabric 11 of a floor carpet as an interior material is placed between a lower mold 32 and an upper mold 33. The end portion 11a of the original floor carpet 11 is held by a movable clamp 57, and the original floor carpet 11 is held under an appropriate tension. At this time, the backing material 15 side of the floor carpet original fabric 11 is arranged so as to face the lower die 32.

Next, the lower mold 32 and the upper mold 32 are matched in the usual manner. As the convex portion 36 of the upper mold 33 presses the original floor carpet 11 against the concave portion 34 of the lower mold 32, the movable clamp 57 moves the lower mold 3
While being pulled and moved toward the end edge 42 side of 2,
The original floor carpet 11 is inserted into the concave portion 34 of the lower mold 32. At this time, the raw material 11 of the floor carpet comes into contact with the rotating member 45 of the edge portion 42 of the lower die 32, and is pressed and inserted into the concave portion 34 while contacting this rotating member 45. That is, the roller 46 of the rotating member 45 rotates.
