摘要： According to embodiments of the present invention, there is provided a stripper assembly and a mold stack incorporating same. More specifically, there is provided the stripper assembly (212) for use in a mold stack (202) for forming a preform (210) suitable for blow-molding into a final-shaped container. The stripper assembly (212) comprises a stripper plate (214) connectable, in use, to a stripper plate actuator; neck rings (220) configured to cooperate to define a portion a neck region (226) of the preform (210); a stripper ring (230) configured to define at least a portion of a top sealing surface of the neck region (226) of the preform (210); the stripper plate (214) being configured to actuate the neck rings (220) and the stripper ring (230), in unison, along substantially the whole length of a complete ejection path, which is substantially parallel to a longitudinal axis of the mold stack (202); and wherein the neck rings (220) are configured for movement in a direction substantially perpendicular to the longitudinal axis of the mold stack, over at a portion of the complete ejection path, whereby at a completion of the complete ejection path, the stripper ring (230) and the neck rings (220) render the preform (210) removable from the mold stack (202).

摘要： An injection mold including a connecting structure for separating confronting faces of a slide member and a mold base, respectively, during a movement of the slide member. In accordance with several embodiments of the invention, the connecting structure may include a compressible member such that the slide member is biased away from the mold base, and wherein a positive contact between the confronting surfaces is configurable in response to an applied clamping force between the slide member and the mold base. In accordance with an alternative embodiment of the invention a cam arrangement links the slide member and the mold base enabling a positive contact between the confronting surfaces when the slide member is arranged in the in-mold position, and providing a gap between the confronting surfaces during at least a portion of an interval when the slide member is moving.
