PURPOSE: A hidden-parting mold is provided to prevent the damage of a cavity stopper even in malfunction by elastically varying the whole length of a stopper block. CONSTITUTION: In a hidden-parting mold including a couple of stopper blocks(30), one end of the stopper block is elastically varied perpendicular to the lifting direction of a mobile holder(13) while the mobile holder moves up/down. One end of the stopper block is fit into a coupling groove(14b) formed at a cavity stopper(14). The stopper block includes a block housing member coupled to a fixed plate(21) and having a hollow groove, a block protrusion member fixed to the block housing member, and an elastic member elastically moving the block housing member.
