jig

Abstract

The present invention provides a jig that facilitates the alignment of the nozzle injection holes in a molding machine with the locating holes in a die plate. [Solution] The jig is used to align the injection hole of a nozzle provided in a molding machine with the locating hole of a die plate. The jig comprises a first outer surface corresponding to the inner surface of the locating hole, and a projection or first through hole provided coaxially with the first outer surface. The projection has an outer surface corresponding to the inner surface of the injection hole. The first through hole has an inner surface corresponding to the outer surface of the nozzle.
