Adjustment of Mold Slide and Disk.
Adjustment of the mold slide is done by means of two set screws, which adjusts the gib on which it slides. This gib should be adjusted so that the slide has .007 play. This will allow it to work freely.
The mold disk is held in position for casting and trimming the slug by means of pins attached to the vise, called mold disk locking studs. The studs are located in relation to the mold disk locking bushings at the factory so as to give perfect alignment of the matrices. They are dowelled in place and should never be changed.
Should the bushings or studs become badly worn at any time, renew them and thus keep the alignment perfect.
The forward motion is imparted to the mold slide by means of a roller which runs in a groove in the mold cam and driving gear. This roller is connected with the mold slide lever by means of an eccentric pin that has a pin attached, which serves as a handle with which to adjust it.
To adjust the slide, loosen the screw which holds the eccentric pin with the T or a small monkey wrench, and turn the handle so that the slide will come forward until the face of the mold is within .01 inch of the vise movable jaw at the time when the line in first elevator is to be justified. If pin is set so as to throw the disk too far forward it would bind the spacebands and matrices and prevent the justification levers from driving up the bands sufficient to space the line, which would cause an indention of the line. On the other hand, if the mold disk does not come forward far enough, it will not give a good lockup, owing to the metal pot having to spring the disk too far in making the final lockup.
