ABSTRACT:
This disclosure concerns dies for die casting machines having a stationary or cover die and a movable or ejector die which has a movable slide mounted thereon. A tapered trough is provided across the slide and into opposite sides of the movable die, and the cover die is provided with a floating wedge that fits into the full length of this trough for positioning and locking the slide with respect to the movable die on which this slide is mounted. The floating wedge may be held in the cover die by flanges on the wedge which loosely fit in grooves in the cover die. The tapers on the wedge and the sides of the trough are complimentary for locking the movable die parts together when all the die parts are closed for filling the cavity formed by the die parts with molten metal.
