EJECTOR GUIDE BLOCK

The outer end of the ejector blade is held in place and guided by the ejector guide block which sets directly back of the flange of the mold disk, and is held by two machine screws passing through each end of the block into the mold slide. This guide holds the blade in position so it will pass squarely through the mold. It also helps the buffer spring to steady the forward motion of the ejector. The point of contact of the ejector block with the ejector blade is made of brass and is held against the blade by spring tension.

The ejector blade guide should be kept free from oil, dirt, and metal shavings, as these impair the free working of the guide. The brass strip should be replaced when worn. Loose screws or a worn brass strip will cause slugs to be thrown out on the floor.

To Change an Ejector Blade

Push in on the starting and stopping lever; let the vise down to first position; back the machine by pushing back on cam No. 1 until the second elevator falls on the safety hook; turn the mold disk until the slot is in front of the blade; push the ejector lever forward; remove the blade by reaching the right-hand in alongside the mold slide and grasp the releasing lever and draw it towards the front. Change the blade for the size wanted, and then let machine come to normal position. Be careful not to get a blade wider than the slug to be cast or there is danger of damaging the liners, or the mold will be damaged. A good plan is always to check up on the ejector blade after changing the liners.
