Abstract: Apparatus for spacing and moving parts, as in a hydraulically operated molding press, arranged for relative movement in which there are means for engaging with and disengaging from the parts at predetermined positions. In a molding press, the apparatus is fitted internally and operates to separate the two mold cavity plates from the fixed clamp plate, positioning the three plates in a spaced relationship. The apparatus also provides for an early return of the ejector plate to in effect withdraw the ejector pins from the mold cavities before the mold closes after the molded piece has been ejected.
