Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the manufacturing method of an interior panel having four deep sections at required locations, such as the interior panel of an automobile door.

An interior material that covers the surface of the base material by bonding a skin material covering the recesses and a skin material different from the skin material to the surface of the base material that has four deep parts at required locations has an excellent decorative effect. Therefore, it is widely used for automobile interior panels, etc., but in order to manufacture this type of interior panel, four parts are pre-formed, small suction holes are provided in the base material, and a thermoplastic synthetic resin sheet is attached to this. equipped,
Under heating conditions, suction pressure is applied through the small suction holes to make it follow the surface of the base material, and then unnecessary parts on the periphery of the four parts are cut off and this part is covered with a different type of skin material. Since it is manufactured normally, there is a problem in that there are many unnecessary cuts 17, which increases the product cost.

The present invention was completed with the aim of producing an interior panel manufacturing method that solves the above-mentioned problems.One mold having a convex part and the other mold having a concave part are brought into contact and separated from each other in a manner F. A skin material previously formed into a shape to fit into the convex part of one of the molds is placed in contact with the convex part and held under suction, and the other mold is A base material that has been previously formed with four parts to be fitted into the concave part is set by fitting the four parts into the concave part, and the convex part is molded to form a skin material on the part of the base material that includes the four parts between the two parts. The method is characterized in that it is bonded using an intervening adhesive, and embodiments of the present invention will be described in detail below with reference to process diagrams shown in the drawings.

(1) a) A thermoplastic synthetic resin sheet of the vinyl chloride resin sheet is molded using a vacuum forming method to estimate the shrinkage rate in advance.1. This is the skin material side that was vacuum formed with a holder. The material is subjected to an I-ming process and separated into individual skin materials (2) as shown in FIG. (3) and (4) are a pair of molds which are provided facing each other and have a convex portion (3a).One mold (3) has a large number of small suction holes (5). ), and a part of the dk type (3) including the convex part (38) does not correspond to the convex part (30). Place the processed skin side (2) on the convex part (3→
The il side is brought into contact and suction is held and the skin +4' (6) of a different type from the skin material (2) is also suctioned and held on the other part (31+) of the mold (3). Skin material (
A molding material (7) is interposed between 2) and (6) as necessary. Furthermore, the other mold (4) has the convex portion (3).
A concave part (lB) corresponding to a) is provided in the other mold (4), d, a concave part σa fitted into the concave part (p a), a base material (8) made of a resin plate, etc. 1 part of the four τ (
Fit and set the four parts σa) to l/, a). When the preparation is completed in this way, one mold (3) is molded to the other mold (4) and the recess ωa of the base material (8) is
) to the part containing the skin material (2) with the adhesive (9) interposed between them, and to the other part of the base material (8) a skin side (2) of a different type from the skin material (2). 6) with the adhesive (9) interposed between them, and at the same time glue both skin materials (
If the joints of 2) and (6) are connected with the molding material (7), the interior panels covered with different types of skin materials (2) and (6) will form both types (3) and (4). Since it can be obtained in a short period of time, it can be made into a product by subjecting it to terminal treatment after demolding. In addition,
In the above embodiment, the two skin materials (2) and (6) are bonded to the base material 1 [8] at the same time, but they may be bonded separately, or both skin materials ( 2), (6)
The seam between the two may be directly connected in advance by means such as high frequency welding, and it goes without saying that the skin material (2) may have a batt material laminated on the back surface. The interior side that was waiting in this way has a pre-formed skin material ('l) glued to a part of the base material that includes the deep recess σ~, so small holes for suction are arranged. Compared to the case where the skin material is formed by suction using the I-based base d and 12 pieces are attached at the same time, the 11M shrinkage stress that occurs after the skin material is formed is relieved, so that the adhesion is strong over time. The surface material will not peel off and the surface material will float, giving it a beautiful appearance.
y11! There are various advantages such as a reduction in unnecessary cut-off parts when carving the skin material ``jc'' compared to the '14 G plastic sheet, so that the product cost can be lowered.

Therefore, the present invention if: (1-): The present invention solves the problems of the conventional manufacturing method of this type of interior material, and contributes to the development of the industry in a very significant manner.

Claims (1)

[Claims] One mold having a convex part and the other mold having a concave part are made to face each other so as to be able to come into contact with each other, and the skin is pre-formed into a shape that fits into the convex part of one mold. A is brought into contact with the convex part with its surface side and held under suction, and the other mold is filled with a base material on which the four parts to be fitted into the concave part have been previously formed, and the concave part is fitted into the concave part. A method for manufacturing an interior board, characterized in that the outer skin material is adhered to a portion including the four parts of a p base month with an adhesive interposed between the two molds by setting the two molds together.
