On old style machines the bushings are in the disk, and the studs are in the blocks. On all the new machines the studs are in the disk and each bushing and block is made in one piece. The blocks are held to the vise by the screws and dowel pins that pass through the front of the vise and screw into the blocks. The left-hand stud block on the newer models is loose sidewise, which permits the studs to enter the stud blocks with the minimum amount of wear to the parts.
The stud blocks can be renewed by taking the old ones off one at a time and using the remaining block as a guide.
The studs should be kept lubricated with a little graphite and grease. Too much will collect on the mold and get to the matrices.
EJECTOR SLIDE
The ejector slide is connected to the ejector lever, by means of a link, and is located in the channel cut in the side of the mold slide. It is operated by the ejector cam, which comes in contact with the ejector lever pawl. The cam is held tight to cam No. 9 by means of a screw and dowel pin. After the ejector lever is brought forward, it is pushed back into position by cam No. 10 coming in contact with a projection on the ejector lever. There is a buffer spring placed on the ejector slide which prevents the slide falling forward with a sudden jerk after the ejector lever has passed its center of gravity and the slug has passed the resistance of the trimming knives. The spring works on a rod which banks against the ejector blade guide. If this spring is not functioning, the slug will be thrown out on the floor.
EJECTOR BLADE
The blade is connected to the ejector slide by the pins that pass through the holes in the blade, the pins being operated by the springs, throw-out cam, and lever. The blade pushes the slug out of the mold, between the trimming knives, into the chase channel.
When the ejector blade advances to the ejecting position the front end should come flush with the bracket on the chase or galley. If it advanced beyond, the slug would be pushed out of the galley to the floor. If it does not advance flush, the slug not being pushed all the way out, would be turned to the right by the slug lever. The adjustment is made with the screw that passes through the ejector lever pawl.
If the blade advances beyond the bracket, turn in the pawl screw and raise the pawl. The higher the pawl is raised, the less distance the slug advances.
On machines that have the inclined galley, adjust blade to come flush with the bevel on the knife block liner.
