specific Embodiment approach

[0038] Hereinafter, preferred embodiments not intended to limit the scope of the present invention will be described with reference to the drawings. The drawings are simplified for convenience of description, and the dimensions do not necessarily have to be the same.

[0039] figure 1 (a) shows a rear dome panel 11 as a ribbed vehicle interior part according to an embodiment of the present invention, figure 1 (b) shows the A-A cross-sectional view of the rear shelf panel 11 .

[0040] The tailgate 11 is a cover member covering a trunk portion of a vehicle, and is composed of a tailgate main body 12 and reinforcing ribs 13 ( 13 a , 13 b , 13 c , 13 d , and 13 e ).

[0041] The tailgate main body 12 is formed by laminating a skin material 16 on a sheet-like (thin-plate-like) thermoplastic base material 15 and press-molding, and has a substantially square planar shape and uneven cross-sectional shape.

[0042] The tailgate main body portion 12 is formed by simultaneously press...

Abstract

In order to improve strength and rigidity without increasing sheet thickness, a method for easily forming a rib as a reinforcing material in press moldings and a press molding having a reinforcing rib are provided. This method for manufacturing press moldings with a reinforcing rib is characterized in: comprising a press molding process for simultaneously press-molding a reinforcing rib and a thermoplastic base material sheet that are each disposed in the press molding die; the reinforcing rib being obtained by a thermoplastic rib base material and a fiber sheet material in which multiple fibers have been accumulated and bonded being stacked and integrally molded so as to have a main reinforcing rib portion and a bonding portion for bonding to the thermoplastic base material sheet; the fiber sheet material having voids between the fibers; and some of the heat-softened thermoplastic base material sheet entering the voids of the fiber sheet material located in the bonding portion during the press molding process and being fixed.

Description

technical field [0001] The present invention relates to a press-formed product with reinforcing ribs in which reinforcing ribs are joined during press-molding of molded products such as vehicle interior parts and exterior parts, and a method for manufacturing the same. Background technique [0002] Automotive interior parts such as door trim (door panel), roof panel, trunk rear shelf (rearshelf), trunk trim, and vehicles such as engine under cover (under bracket) and inner fenders The exterior parts are formed by press-molding a base material made of a sheet-like (thin-plate-like) thermoplastic material, so it is a product with a uniform overall thickness. Ensuring a sufficient plate thickness in order to increase the strength and rigidity of such interior parts and exterior parts leads to an increase in weight and material costs. [0003] Therefore, in order to increase the strength and rigidity of the inner and outer parts without increasing the plate thickness, it is con...
