Abstract
The present invention relates to a metal mold for producing a synthetic resin molded product in a compression-molding method, which is comprises a pair of male and female molds which are allowed to mutually slide over a contact face, with the outer circumferential face of the male mold and the inner circumferential face of the female mold serving as sliding portions at the time of mold-clamping, characterized in that either the male mold or the female mold or both of the molds is constituted by a mold main body and a sliding member. The sliding member forms a portion of the metal mold over the entire sliding portions or on a portion thereof, and is removably attached to the mold main body. The same metal mold may be used for production of a non-laminated synthetic resin molded product and a laminated product having the same design by replacing only the sliding member, without the need for using different molding devices corresponding to the respective production processes.
