Abstract
A plastic injection mold is disclosed which is particularly suitable for molding plastic objects such as containers. The mold has a core assembly and a mating cavity assembly which define the shape of the object to be molded therein. Movable collets are located in the mold to define the shape of a portion of the object, such as a peripheral flange or rim. The collets are slidably guided by cam pins, so that upon opening of the mold, the collets can be lifted by actuators to separate and release the molded object. A collet lifting ring is located between the collets and the actuators to ensure that all of the collets separate simultaneously.
