ABSTRACT:
A closed injection mold for molding liquid resins into molded plastic articles containing at least one vent apparatus having a reciprocating vent pin operative to retract to open the vent opening and extend to close the vent opening. Each vent apparatus is responsive to a full resin level in the mold cavity to close the vent opening. When the vent opening is closed, cleansing fluid is automatically circulated through the debris charge line of the vent apparatus to clear the venting channels prior to the resin debris hardening.
