Abstract
A porous spacer incorporates a vaporizable corrosion inhibitor. The spacer is designed to be placed on a leader pin between the members of a mold or die set. The spacer is compressed between the members when the latter are stored. The spacer releases the inhibitor, which prevents corrosion during the storage period. The spacer serves to maintain a vapor flow space between the members.
Claims14
Apparatus for protecting metallic surfaces of first and second die members interconnected for storage by at least one leader pin which comprises:
- at least one porous spacer mounted on said leader pin between said first and second die members, said spacer being impregnated with a vaporizable corrosion inhibitor.
Apparatus for protecting metallic surfaces of first and second die members interconnected for storage by at least one leader pin which comprises:
- at least one porous spacer body telescopingly mounted on said leader pin between said first and second die members, said spacer body being impregnated with a vaporizable corrosion inhibitor, said body having at least one edge and means defining an opening positioned near said edge to receive and embrace said leader pin.
