- and
- a clamping-force receiving portion shaped and arranged to allow the roll-type decorating film to pass entirely and continuously through the passing region between said mold members when said mold members are in a joined position, said clamping-force receiving portion arranged around said mounting face substantially symmetrical with respect to a center line of said first one of said mold members along a passing direction of the decorating film, so as to be outside of the passing region of the decorating film;
- wherein one of said dieset and said cavity-forming block includes an engagement recess portion, and the other one of said dieset and said cavity-forming block includes an engagement protruding portion, said engagement protruding portion and said engagement recess portion being shaped and arranged to engage each other so as to position said cavity-forming block at said mounting face of said dieset and mount said cavity-forming block on said dieset.
