Abstract
This invention provides a mold for a gasket, which can render the planar shape of a mold for integral molding of a large-diameter gasket as small as possible to reduce the size of the manufacturing equipment and, at the same time, by virtue of integral molding, does not require labor and time in the manufacture thereof and does not cause a lack of strength in the connecting part. To this end, a mold () for molding an endless-type gasket comprises a plurality of molding parts (), formed by disposing two molding grooves (), in a spiral wound form, in parallel so as to be adjacent to each other. The spiral wound molding grooves () have reversing parts () in their respective inner ends (), and, at the same time, their outer ends () are connected to each other in a rope form.
