ABSTRACT:
A mold structure for press molding, including an upper mold member and a lower mold member in a sleeve member in longitudinally slidable manner. The mold includes a member for limiting the movement of the lower mold member with respect to the sleeve member in a direction in which the lower mold member is separated from the upper mold member, and a ring member mounted on the upper end face of the sleeve member. The ring member is provided, in the longitudinal direction of the sleeve member, with at least three penetrating holes in which pins with same length are detachably inserted, and the upper mold member has an impinging face to be brought into contact with the pins in the pressing operation, thus determining the thickness of the molded article.
