Abstract
A length adjustable extension bar for connecting a mold ejector plate to a press ejector plate comprises a rotatable member threadingly secured on one end of a threaded stud. An opposite end of the threaded stud is connected to the press ejector plate and a distal end or head of the rotatable member is connected to the mold ejector plate. Rotation of the rotatable member relative to the threaded stud increases or decreases the overall length of the extension bar. A locking assembly comprising a locking sleeve biased by a spring into engagement with a locking nut is mounted on the extension bar to prevent adjustments in the length of the extension bar without first advancing the locking sleeve out of engagement with the locking nut. The locking sleeve is slidably mounted on the rotatable member shaft but is prevented from rotating relative to the shaft by a pin extending through the rotatable member shaft and aligned slots formed on opposite sides of the locking sleeve. The spring is positioned on the rotatable member shaft between the rotatable member head and the sleeve to bias the sleeve toward and into engagement with the locking nut.
