SLIDE ACTION COMPONENTS Slide Retainer Assemblies
The DME Slide Retainer provides a compact and economical means of slide retention, which makes obsolete the cumbersome external spring or hydraulic methods. Its simple and positive operation makes it equally suitable for new tooling design or retrofitting existing molds. Available in three sizes with increasing weight-holding capacities, the Slide Retainers can be used individually or in multiples for larger or heavier slides. Generally mounted behind and below the slide (see drawing at right), the DME Slide Retainer is a compact unit that can be entirely contained within the mold. Interference with machine tie bars or safety gates is no longer a problem. (It can even be installed completely underneath the slide if space is limited.) As the mold opens, the dowel pin installed in the slide positively locks into the retainer until disengaged by the mold’s closing action. The custom-designed spring placed crosswise in the retainer maintains the force required to keep the dowel pin in the jaws when the mold is open. The Slide Retainer is designed with a generous lead-in at the jaw opening so the dowel pin will enter the jaws even if there is a slight misalignment between the retainer and the pin.
