TACTICAL VENTING

A method of venting a rotational mold (2) at a predetermined condition by actuating an actuating venting assembly (10) wich pierces the shell of the molded article (4) and introduces a passageway to relieve pressure during the molding cycle. The actuating venting assembly enables a tactical methodol...

Beschreibung
Zusammenfassung:	A method of venting a rotational mold (2) at a predetermined condition by actuating an actuating venting assembly (10) wich pierces the shell of the molded article (4) and introduces a passageway to relieve pressure during the molding cycle. The actuating venting assembly enables a tactical methodology for venting such molds. La présente invention a trait à un procédé de mise à l'air libre d'un moule rotatif sous une condition prédéterminée par l'actionnement d'un ensemble de mise à l'air libre entraînant la perforation de la coquille de l'article moulé et l'introduction d'un passage pour la décharge de pression lors du cycle de moulage. L'actionnement de l'ensemble de mise à l'air libre permet une méthodologie tactique pour la mise à l'air libre de tels moules.
