Abstract

A mold for manufacturing a skin covered foamed plastic seat capable of effectively dealing with the variations in shape and position of the trim ends. The mold includes stopper means for fastening the trim ends attached to the edges of the skin cover, located between the upper mold and lower mold separately from a space into which a liquid foam resin is to be poured, each of the stopper means having a slit through which one trim end is inserted, and a top face portion to which both ends of the trim end are to be hooked.

Claims

1. A mold for manufacturing a skin covered foamed plastic article using a skin cover having edges and trim ends attached to the edges, comprising:

an upper mold;

a lower mold to be assembled with the upper mold to form a cavity into which a liquid foam resin is to be poured over the skin cover when placed on the lower mold, the lower mold having at least one edge portion located outside of the cavity formed by assembling the lower mold and the upper mold; and

at least one stopper means located on the edge portion of the lower mold, for fastening the trim ends attached to the edges of the skin cover, each stopper means having a slit through which a trim end is inserted and a top face portion to which edges of the inserted trim end are hooked when the skin cover is placed on the lower mold.

2. The mold of claim 1, wherein the upper mold has at least one concavity to form at least one space in conjunction with the edge portion of the lower mold, the stopper means being contained inside the space when the upper mold and the lower mold are assembled.
