A mold assembly is provided to improve operating reliability of the mold assembly by preventing an angular pin and a slide core from being pushed in a direction that the angular pin and slide core get away from an article. A mold assembly comprises a first disk(12) which is installed on a fixed plate(10) and has a first main core(15) having a shape corresponding to that of an article(M), a second main core(45) which is installed on a moving plate(30) and selectively adhered closely with the first disk, and cooperates with the first main core to form a cavity, a second disk(40) having a recessed placing groove(43) formed on a top side thereof facing the first disk, a slide core(50) which forms an undercut(M') shape on the article, and into which an angular hole(52) is penetrated, and an angular pin(20) which is selectively inserted into the angular hole to move the slide core, and of which a front end is inserted into the placing groove when the first and second disks are closely adhered to each other.
