Urethane foam molded article, manufacturing method thereof, and magnetic induction foam molding apparatus

摘要

A magnetic induction foam molding apparatus comprising: a pair of electromagnet parts (2u,2D), each of which has a core part composed of a ferromagnet and a coil part placed on the outer circumference surface of the core part, and that are placed so as to face each other and depart from each other with a predetermined distance in the axis direction of the core part; a foaming mold (4) interposed between the pair of electromagnet parts (2u,2D), inside which a cavity (41) is defined; and a yoke part (3) connecting back surfaces of the respective core parts of the pair of the electromagnet parts (2u,2D) so as to form a magnetic path between a pair of the back surfaces. In the cavity (41) of the foaming mold (4), a uniform magnetic field is formed.
