  • Patent number: 5538067
    Abstract: A holding member (22) which can hold a predetermined axial-length laminated core member by pressing down both axial end faces thereof is used to hold a short laminated core member (24) and a spacing element (48) having a thickness generally equal to the difference between the axial lengths of those laminated core members. The spacing element is disposed at a position between one axial end face of the laminated core member (24) and a lid element (32) of the holding member (22). The laminated core member (24) and the spacing element (48) are both held by the holding member (22) and are introduced into the mold (20) to form a conductor portion integrally with a predetermined axial-length laminated core member held by the holding member (22). In this state, molten metal is poured into slots (38) of the laminated core member (24) and annular cavities (44, 46), and thus a conductor portion is formed integrally with the laminated core member (24) when the molten metal is set.

  • Patent number: 5078202
    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.
