Abstract: A friction puller (100) for an injection mold is disclosed. The friction puller has a bolt (110) with a head portion (105) and a threaded portion (120). The friction puller has first and/or second first substantially- hemispherical wedges (130) having a first and/or second passages (150) running through them for the bolt and allow lateral float about the bolt. The friction puller also has a deformable jacket (160) having a third passage (190) running through is for the bolt and first and second substantially hemispherical cups (180) for receiving the first and second substantially hemispherical wedges. The first hemispherical wedge can have a vent relief notch (140) disposed in a top surface of the first hemispherical wedge. The deformable jacket (160) can have a jacket vent notch (140) disposed in a top surface of the deformable jacket. The bolt head and the jacket can have alignment indicator marks thereon. The bolt threads can have a variable pitch diameter.

Abstract: The present invention includes an improved ejector sleeve (5) having thinner side-walls than prior sleeves. The sleeves generally include a ring (31) for mounting the sleeve, a central bore (42) for receiving a core pin (1), a tube portion extending from the ring to a tube end portion. The side-walls defining the tube end portion have a thickness of less than forty thousandths, and preferably thirty thousandths of an inch. Preferably, the coated ejector sleeve is provided in which a thin, lubricous coating of nickel, chromium or alloys of chromium or nickel is applied to at least a portion of the sleeve. The coating is applied in thickness of less than .0001 inch which improves the wear characteristics of the pins and sleeves as well as allowing the coated pins and sleeves to be stocked and used as nominal thickness parts.
