Abstract
A saw guide bearing casting machine includes a pair of mold plates selectively movable by a cylinder between a closed operative position defining a mold cavity for receiving molten babbitt material and forming material into a saw guide bearing. The first mold plate includes a flat planar portion of the mold cavity. The second mold plate includes the remainder of the mold cavity, for forming the sides and face portions of the bearing. The second late slides on guide rods while the first plate is held stationary. Ejection pins and hole forming plugs and studs are provided on the second plate. The ejection pins slide within the second plate and through a stationary stop plate. Abutments are mounted on the ejection pins on opposite sides of the stop plate. Inward abutments strike the stop plate as the second plate is retracted, to force the cast bearing to drop from the mold. Outward abutments strike the stop plate as the second plate is closed to position headed ends of the ejection pins into complimentary depressions in the second mold plate such that flat ends of the pins are coextensive with the adjacent surfaces of the mold cavity. The studs and plugs are axially adjustable, as in a removable section of the second plate to allow for selective adjustment of the bearing thickness.
