摘要

A traverse is mounted above a mold for movement vertically toward and away from the same. It carries plungers which can enter into the mold, and a hydraulic unit which can be operated to press the traverse and plungers downwardly against the mold. A mobile abutment is mounted on a stationary support and travels with the traverse to provide a mobile reaction point for the hydraulic unit when the latter with the traverse has reached a lowered position in which the transmission of pressure from the unit to the traverse is required.
