Abstract

PURPOSE: To mold a cushion body with an excellent performance having a slit and a through hole inside by injecting a raw liquid for urethane foam in a specified procedure employing a special die having a rib inside.
CONSTITUTION: A cushion body integrating a surface materil 5, an adhesive cover 12 and a urethane foam is molded provided with a slit 3 extending deep to the middle of an urethane foam 7 from the surface material 5 and a hole throughly piercing. In this process, the surface material 5 cut out to the shape of the die is inserted into a mold which has a rib 14 with a pin at the tip thereof inside the lower die 13. The mold is formed in the same shape as the slit 3 with a height equal to the thickness of the surface material 5. An adhesive cover is solidly applied on the material 5 and a baffle bar 18 is fitted into the pin 15. Thereafter, an urethane raw liquid 16 is poured over the cover to mold.
