Problems solved by technology

[0009] However, when the end treatment is performed on a laminated material having a complex curved shape, when the method disclosed in this Patent Document 1 is used, in the part having a complicated curved shape, the bent portion of the bend occurs. large creases, so the bend cannot be brought into good contact with the side end of the laminated blank
That is, in the above-mentioned end treatment method, there is a problem that the shape of the laminated material is restricted.

Abstract

Provided are a technique for realizing a laminated plate capable of improving the appearances of end portions and the degree of shaping freedom, and a terminal treating method for a laminated material. When a cooling-press upper mold (80) drops, a design forming protrusion (82) pushes both a portion of a surface member laminated material (1d) on the inner side of a deposited portion (6a) and an inclined end portion (6b) downward. On the other hand, the untreated portion of the surface member laminated material (1d) is pushed to a forming face (72) of a lower face (81). Both the portion of the surface member laminated material (1d) on the inner side of the deposited portion (6a) and the inclined end portion (6b) are crushed by a design forming face (73) of a cooling-press lower mold (70) and the design forming protrusion (82) of the cooling-press upper mold (80), so that they are pressed into desired shapes.

Description

technical field [0001] The present invention relates to a laminated sheet and a laminated material end treatment method, for example, relates to a laminated sheet material and a laminated material end treatment method used as interior materials for automobiles and the like. Background technique [0002] In automobiles, resin molded products have conventionally been used as interior materials such as trunk panels and door trims. Furthermore, in recent years, more attention has been paid to the two features of "lightweight" and "complicable to complex shapes", which are characteristics of resin molded products. [0003] The structure of the resin molded product includes, for example, a highly rigid hollow structure, a lightweight and highly rigid sandwich structure, etc., and it is selected according to the required strength, shape, and function. [0004] Conventionally, as a laminated material of a sandwich structure, for example, a structure in which cover plates are lamina...
