How to Absorb the Center Offset of Ejector Rod
The Ejector Coupler has no ﬂoating function, so it is required to provide the ﬂoating
function in order to absorb the center oﬀset of the ejector rods.

Floating on the Mold SideThe method to provide ﬂoating margin on themold side that absorbs the center oﬀset. Wheninstalling the Ejector Couplers on existing molds,
the molds need to be modiﬁed.

Notes :
※1. Design the ejector rod with a gap (0 ~ 0.5mm) between the ejector plate and socket at the ejector plate backward positionin order to prevent the load applied on the connecting part of the manual ejector coupler.
Make sure to install return pins since the ejector pin cannot be fully moved backward due to the gap.
※2. Insufficient tightening torque causes looseness and breakage.
