INJECTION FOAMING MOLDED ARTICLE, INJECTION FOAMING MOLD, AND MANUFACTURING METHOD OF INJECTION FOAMING MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide an injection foaming molded article composed to be easily and surely molded to have good appearance of end edges with simple configuration, and an injection foaming mold and a manufacturing method of the injection foaming molded article with good appearance of the end edges. SOLUTION: A base material 1 having a protrusion 5 at the corner part of the surface 1a of an end part is molded, a cavity 18 is formed by a second mold 12 and a third mold 13 holding the base material 1, and materials of a facing and a foaming material 4 are injected and filled into the cavity at given pressure. Part of the materials of the facing and foaming material 4 in contact with the third mold 13 is solidified to form a facing layer 2 and the third mold 13 is subjected to core-back to form a foaming layer 3 to the integrated part 4b. A winding part 4a is molded relatively thin only by the facing layer 2. Thus, the winding part 4a can be wound and joined to an end part rear face 1b of the base material 1 with good appearance.
