Abstract
A mold for skin covered foamed plastic molding which utilizes a middle mold to be placed between an upper mold and a lower mold capable of preventing penetration of the liquid foam resin to be poured onto the skin cover, and also capable of improving the efficiency of the manufacturing process. The mold includes a middle mold configured for reducing pressure exerted by the liquid foam resin falling on the skin cover.
