■ Features of the assist rod type
■ Features of the assist rod type • The assist rod is installed in the ejector space parallel to the inclined pin, and the load on the inclined pin is reduced by having the assist rod bear the operating resistance of the inclined pin holder.
• Supports the cases where a large load is applied by the inclined pin • Supports steeper inclined pins • Supports steeper undercut angles • Supports smaller inclined cores and thinner inclined pins
