ABSTRACT:
A mold for manufacturing a skin covered foamed plastic article in which the middle mold is to be attached to the upper mold so as to eliminate the attaching and removing of the middle mold for every manufacturing cycle, without creating a danger of damaging the manufactured skin covered foamed plastic article in taking it out of the mold. The mold includes a middle mold to be attached to the upper mold such that when the upper mold is lifted upwards in order to be disassembled from the lower mold, the middle mold also moves upwards and the skin covered foamed plastic article is taken out from the lower mold by the upper mold and the middle mold; and a protrusion for making a hole in the skin covered foamed plastic article to be manufactured, to be attached to the molding surface of the lower mold, which is freely detachable from the lower mold such that when the upper mold is disassembled from the lower mold, the protrusion is taken off the lower mold along with the skin covered foamed plastic article.
