Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is based on the para F E (1 core plate covered with one skin material).
This article [) relates to a method of manufacturing a plate.

Pad material such as polyurethane foam with chloride L' = Back surface of skin material such as resin sheet 1. Interior board made by laminating padding material and skin material adhered to core board is not recommended for automobile interior because it wrinkles and becomes loose. This type of interior board is widely used, but when the end edge of the padded skin material is folded back to the back of the core board at 1P9a and the end edge is processed, the end edge of the core board bulges out. The edges are formed and you cannot get a sharp edge.
This terminal processing adds 7 extra steps! - There was a problem that.

The present invention provides a pad 1411 that solves the above problems.
The interior board has a 4-year-old skin covering the core board! It was completed 1i2 for the purpose of the 1II1 manufacturing method, and the skin material with padding material was placed on the core plate set on the lower part. In the NK~ method of an interior board in which a core plate is covered with a padded skin IJ which is pressurized and bonded and the 'rFi end of the pad material 111 skin material is folded back to the back surface of the core board to perform terminal treatment, When pressurizing and adhering the padded skin material to the core plate using the upper die, the free end of the core band adhesive skin material is attached to a chevron provided on either the upper die or the lower die outside the edge of the core plate. The pad material tr is characterized in that a linear crushed portion is provided by applying pressure with the raised portion, and the free end portion of the band interest-bearing skin material is folded back to the back surface of the core plate using the linear crushed portion as a folding line. There it is,
Hereinafter, embodiments of the present invention will be described in detail with reference to illustrated process diagrams.

(1) is a lower mold with a shape in which the core plate (2) can be set, and the mold part (c) of the core T-type (1) is made of hardboard, insulation board, synthetic resin board, etc. A core plate (2) made of material pre-formed into the required shape is set, (3
1 is a skin material with padding material to be covered by the core plate (2), and the skin material with padding material (3) is made by combining a padding material (4) such as polyurethane foam with a thermoplastic composite such as a vinyl chloride resin sheet. It is laminated on the back side of the resin sheet (5) and then molded into the desired shape using a vacuum forming method so as to apply a slightly larger force than the core plate (2), and if necessary, adhesive is applied to the back side of the pad material (4). The free end portion (2) of the core plate (2) set in the lower mold (1) was coated with
3b) is an upper mold that supports the horizontal surface part (/b) of the lower mold (1), and the upper mold (6) has the lower mold (the mold part (/a)
A chevron-shaped vk@ part (7) is provided so as to be located on the outer side of the edge of the core plate (2) set in the core plate (2). Then, place the skin material with padding material (3) in the above state on the core plate (2) on which the lower mold Q) IC is set, and then place the upper mold (6) f.
Lower it and use this upper die (6) to form the skin material with padding material (3
) to the surface of the core plate (2) under heat and pressure, the pad material (4) of the main body of the skin material with pad material (3) will be adhered to the surface of the core plate (2). However, at the same time, the upper mold (6) has 5 parts located outside the edge of the core plate (2).
) Since the chevron-shaped raised portion (7) is provided, the skin material with pad material (3) has the core plate (2) as shown in FIG.
The pad material (4) corresponding to the outer side of the end edge is crushed into a valley shape to form a linear crushed part (30) at the base of the free end part (3b). ) is lifted and removed from the mold, the pad material crushing part (30) stuck to the surface of the core plate (2) prevents the pad materials from being compressed together in the folded part, making the folding work easier. Moreover, as shown in Fig. 3, thermoplastic synthetic resin sheet ) (5
) has a sharp fold to<3.
Since it will appear as a5, the finish of the terminal part will be fine, and the thermoplastic synthetic resin sheet (
5) Since the sides do not become thinner, there is no possibility of grain running or whitening, and an interior board with excellent decorative effects can be obtained.

Moreover, in front! The forming of the i3 linear crushed portion (3C) can be done simultaneously when the padded skin material (3) is bonded to the core plate (2) under pressure, so the process can be omitted and is suitable for mass production. In addition, on the male side, the chevron-shaped raised part (7) is provided on the upper mold (6), but even if it is provided on the lower mold (1), the pad material (4) is crushed linearly into a trough shape. Part (30)
Therefore, the chevron-shaped raised part (7) only needs to be provided on either the upper mold (6) or the lower mold (1), and the linear crushed part (3C) can be formed in one piece. Alternatively, a plurality of them may be arranged in parallel.

As is clear from the description of the embodiments described above, the present invention includes the following steps:
A chevron-shaped ridge provided on the upper mold or the lower mold when the pad material 41 skin material is pressure-bonded to the core plate at the free end of the padded skin material corresponding to the edge of the core plate. By forming a linear crushed part with the part, the folded part can be easily bent, increasing the work efficiency and achieving a beautiful finish. This work is extremely important in that it contributes to the development of the industry by solving problems in the manufacturing method of interior panels, which are covered with wood as a core board.
