A mold assembly includes a collapsible mount for releasably holding an inse rt within a mold cavity of the assembly in order to integrally form the insert with a molded article such as a tank liner. The collapsible mount includes a number of fingers secured to the mount and capable of being inserted through and expanded to engage th e insert. The fingers are expanded after insertion through the insert by a core engageable with the fingers in order to securely hold the insert in position on the fingers of t he mount and within the mold cavity. After formation of the article around the insert, th e core can be disengaged from the fingers, which then move to a collapsed position such th at the mount can be quickly withdrawn from within the insert and the mold cavity.
