Problems solved by technology

[0006] However, in the conventional door interior trim 1, since the projected area of ​​the resin core material 2 is large, there are problems of high material cost and heavy product weight.
In addition, since the projected area of ​​the resin core material 2 is large, the injection pressure during molding has to be set too high, and a metal mold structure capable of withstanding high injection pressure is required, and the manufacturing cost of the metal mold is expensive. Molten resin cools and solidifies, requiring a longer molding cycle, which is also an important cause of low productivity

Abstract

The invention relates to a method for providing inner decoration part of which comprises layered structure and relative producing method, which can avoid inclined fluff when punching and improve the appearance. The method comprises that the inner decoration is formed by foam resin basic material (21) which is light with form-keeping ability and has a resin rib (22), a layered structure (the upper part of said decoration) whose surface is adhered with additional decoration (23) and a resin monomer element (the lower part of decoration) (30). Wherein, the layered structure (20) can combine the additional decorations (23) which is only processed by low-temperature soft treatment without heating process with the foam resin sheet (S) which is processed by heating soft treatment, to be put into molding metal mould (40), and via low-pressure punching shaping to be integrated. Therefore, the invention can avoid inclined fluff and heat deformation of decoration (23) to confirm better form-keeping ability and reduce the shaping load.

Description

technical field [0001] The present invention relates to automotive interior parts such as door interiors, rear luggage compartment lids, floor interiors, trunk interiors, rear interiors, pillar decorations, roof interiors, and the like, and methods for manufacturing the same. In particular, it relates to automotive interior parts which are light in weight and have good designability and moldability, and a method for producing the same. Background technique [0002] For example, regarding the composition of automotive interior parts, taking the door interior trim as an example, according to Figure 20 , Figure 21 Be explained. The structure of the door trim 1 has shape retention and rigidity for mounting on a vehicle body panel, and a skin 3 with a beautiful surface appearance is laminated on the surface of a resin core material 2 along almost the entire surface of the product surface to make it more attractive. its integration. In addition, reference numeral 2a denotes a...
