Automotive interior component and method for manufacturing the same

An automotive interior component comprising an interior trim main body consisting of a foamed resin base material, which is formed into a required shape and has a light weight and shape holding properties;

• a resin mold portion, which is integrated with a part of the back surface of the foamed resin base material;
• and a functional component, which is mounted on an interior trim main body, wherein
• the functional component is housed and fixed in a mounting opening in the interior trim main body, and a resin rib substantially intersecting with an edge line of a corner edge of the functional component is formed on the inside surface side of the foamed resin base material so as to correspond to the corner edge.

• the functional component is housed and fixed in a mounting opening in the interior trim main body, and a thin reinforcing flash portion that receives an edge line of a corner edge of the functional component is formed on the inside surface side of the foamed resin base material so as to correspond to the corner edge by intentionally and forcedly exposing molten resin (M) to the outside.

A method for manufacturing an automotive interior component comprising an interior trim main body consisting of a foamed resin base material, which is formed into a required shape and has a light weight and shape holding properties, and a resin mold portion, which is integrated with a part of the back surface of the foamed resin base material, wherein

• a raw material sheet (S), which is a raw material for the foamed resin base material, is provided between molding upper and lower dies in an open state after being softened by heat, and the molding upper and lower dies is clamped to mold the foamed resin base material into a required shape along a cavity shape;
• molten resin (M) is injection charged into a concave portion in the molding upper and lower dies just before the molding upper and lower dies is closed or after the molding upper and lower dies has been closed to integrate the resin mold portion with the inside surface of the foamed resin base material;
• and the molten resin (M) is leaked to the outside intentionally and forcedly to form a thin plate shaped reinforcing flash portion at least in a part around the resin mold portion in connect with the base part of the resin mold portion.
