Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interior material such as an automobile door trim and a method for manufacturing the interior material.

[0002]

2. Description of the Related Art An automobile door trim as shown in FIG.
(1) is composed of a base material (2) formed into a predetermined shape and a skin material (3) adhered to the surface of the base material (2). For example, a decorative member (on the upper side of the armrest part (4) ( 5) is installed. The decorative member (5) is different from the skin material (3) in color, color tone, material, etc., and gives the door trim (1) a decorative property.

Conventionally, as shown in FIG. 6, the decorative member of the base material (1) is mounted on the door trim (1) by attaching the decorative member (5).
(5) A wood-graining method in which the mounting portion is surrounded by a groove (6) and the peripheral edge portion (5A) of the decorative member (5) is wood-grained into the groove (6) through a skin material (3), or a drawing As shown in Fig. 7, a welder method was used in which the periphery of the decorative member (5) was welded to the skin material (3) by high-frequency welding.

[0004]

However, in the above wood-graining method, the groove (6) must be formed at the time of molding the base material (1), and the molding die for the base material (1) has grooves and protrusions for that purpose. Must be provided, resulting in high die cost and easy damage to the groove and the protruding portion. Further, it is necessary to provide a groove and a protrusion corresponding to a vacuum pressure bonding die for pressure-bonding the base material to the skin material and the decorative member, which increases the cost of the die as well as the molding die and is easily damaged. On the other hand, in the welder method, the water content of the base material and the humidity of the atmosphere are greatly affected, and the electrodes are short-circuited to increase the welder failure rate.

[0005]

As a means for solving the above-mentioned conventional problems, the present invention provides an interior material (1) body composed of a base material (2) and a skin material (3) lined with a cushion material. The decorative member (5) is attached to a predetermined place of the decorative member (5), and the skin material (3) around the mounting portion of the decorative member (5) is crushed through the decorative member (5) to provide an interior material (1). , A lower mold (8) and an upper mold (9), and a nesting mold (10) with a pressing portion (10A) protruding around the upper part of the upper mold (9) slides up and down. Vacuum crimp type installed as possible
(7) is used, the formed base material (2) is set in the lower mold (8), and the decorative member (5) is vacuum-adsorbed to the insert mold (10) of the upper mold (9). And insert the skin material (3) in a heat-softened state between the upper mold (9) and the lower mold (8) to perform vacuum forming with the upper mold (9) and The skin material (3) together with the lower mold (8) is pressure-bonded to the base material (2) together with the decorating member (5), and the outer mold material (3) is pressed by the edge of the nesting mold (10) of the upper mold (9) Provided is a method for producing an interior material (1) in which a peripheral edge of a decorative member (5) of the skin material (3) is crushed through the decorative member (5).

[0006]

[Function] In the interior material (1) of the present invention, the decorative member (5)
Since the skin material (3) around the mounting edge is crushed through the decorative member (5), it is not necessary to provide a groove for wood grain in the base material (2), so that the structure of the molding die or the vacuum crimping type can be used. It will be easy.

In order to manufacture such an interior material (1), a base material (2) formed in a predetermined shape is vacuum-pressed (7) to a lower mold (8).
Set it on the top and press the surrounding part at the designated place of the upper mold (9).
(10A) is set by vacuum-adsorbing the decorative member (5) to the insert mold (10) protruding, and the skin softened by heating between the lower mold (8) and the upper mold (9). Insert the material (3) and insert
(3) is vacuum-molded on the upper die (9) surface, and the decorative member (5) is pressure-bonded to the skin material (3), and the skin material (3) is attached to the lower die (8).
The base material (2) is crimped between the upper mold (9) and the upper mold (9).

At this time, the press member (10A) of the insert die (10) is used to decorate the skin material (3) on the decorative member (5).
It is crushed via (5). Decorative member in this way (5)
The interior material (1) with the attachment is manufactured. In the above manufacturing process, since the decorating member (5) is set in the insert mold (10), there is no risk of misalignment.

In the present invention, for example, a resin board, a wood fiber board, a cardboard, a polystyrene foam board or the like is used as the base material (2), and the skin material (3) is the surface material (3A) and the surface material (3A). ) And a foam layer (3B)
Polyvinyl chloride as the (3A), a thermoplastic sheet such as a thermoplastic elastomer (for example, a polyolefin-based thermoplastic elastomer, a polyester-based thermoplastic elastomer), a polyethylene foam as the foam layer (3B),
Polypropylene foam, polyvinyl chloride foam, polyurethane foam, etc. are used.

Further, as the decorative member (5), fiber knitted woven fabric, non-woven fabric, natural leather, synthetic leather or polyvinyl chloride leather is used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in FIGS. 1 to 4. A base material (2) of a door trim (1) molded in a predetermined shape by a molding die as shown in FIG. Type
(7) Set on the lower die (8), while the upper die (9) is attached to the decorative member by a hydraulic cylinder (11) or an air cylinder that is vertically slidably supported. 10) is attached, a pressing portion (10A) is projected on the periphery of the insert mold (10), and further a temperature adjusting presser blade (12) is arranged around the insert mold (10), The decorative member (5) is set in the insert mold (10). Both the upper mold (9) and the insert mold (10) are made of a porous air-permeable electric mold or a ceramic mold.

Lower mold (8) and upper mold (9) of the vacuum crimp mold (7)
The skin material (3) is inserted in the state of being softened by heating, and the skin material (3) is vacuum formed by the upper die (9) and welded to the decorating member (5), and at the same time, the skin Material (3) is lower mold
The base material (2) is pressure-bonded between the (8) and the upper mold (9). And the telescopic die (10) and the temperature control blade (12) are hydraulic cylinders (11).
By the pressing portion (10A) of the insert mold (10), the peripheral edge of the decorative member (5) of the skin material (3) is crushed through the decorative member (5), and the temperature control is performed. Decorative member by the presser blade (12)
The periphery of (5) is also crushed.

Thus, the door trim (1) with a decorative member as shown in FIG. 3 is manufactured. In this embodiment, as shown in FIG. 4, a skin material (5) is attached to the periphery of the mounting portion of the decorative member (5). 3)
And the crushed portions (3C, 5D) are formed on the decorative member (5).

Other than the above examples, the skin material (3) and the decorative member
If the weldability with (5) is low, an adhesive may be used, and if it is not necessary to crush the peripheral edge of the decorative member (5), the temperature control blade (12) is not necessary.

[0015]

As described above, according to the present invention, the structure of the molding die and the vacuum pressure bonding die used for manufacturing the interior material with the decorative member is simplified and is less likely to be damaged, and the die cost is greatly reduced.
