<p>In a fixed side and movable side disk cavity plates (19,20) aligning and guiding apparatus for disk injection molding metal dies capable of minimizing the damage of information transferred from a stamper plate, the wear of dies and the like when the dies are opened, there are disposed a plurality of pairs of parallel grooves (21,22) which are formed to the same cross sectional shape and the parallel grooves (21,22) have groove surfaces which coincide with the common outside diameter surface of a fixed side disk cavity plate (19) and a movable side disk cavity plate (20) in parallel with the center line of the dies when they form a cavity space. Each of guide blocks (23) is secured to one of the each pair of the parallel grooves (21,22) and precisely engaged with the other of the parallel grooves. The disk cavity plate (20) of the movable side metal die is mounted to a movable side mounting plate (25) through a self-aligning means for holding the disk cavity plate (20) on a plane in intimate contact therewith under pressure as well as slidably supporting the same, the plane being perpendicular to the axis of the disk cavity plate of the movable side die. <IMAGE></p> |
