초록 ▼

A nozzle apparatus for use in an injection mold comprising a relatively massive body, having a central passageway extending axially therethrough, and a counterbore connecting therewith, having threads formed therein, and having a nozzle tip member, having threads at one end whereby the same may be threaded into said counterbore, and having a central passageway communicating with the central passageway in the body portion, and having at least one opening at its other end, for ejection of plastic therefrom, said body and said nozzle tip member being formed of a good heat conductive material, and a housing shell adapted to fit around said body portion and at least a portion of said nozzle tip member, and, support means formed integrally with said housing, for supporting said housing and said main body portion and said nozzle tip member therein in position.

대표청구항 ▼

An injection nozzle apparatus for use with a die cavity in a mold assembly and which nozzle assembly comprises: a relatively massive body having a base surface and a forward end and having a high heat conductivity; shoulder means on said body for mounting thereof in said mold assembly; a passageway extending through said body from said base surface to said forward end; threaded attachment means at said forward end around said passageway a nozzle tip member threadedly secured to said body at said threaded attachment means and having a passageway therethrough communicating with said passageway in said body at least one opening for the ejection of molten plastics material therefrom; an outer shell partially enclosing said body and exposing said base surface and at least partially encircling said nozzle tip member; flange means on said shell adapted to engage said shoulder means on said body, said shell being adapted to be secured on such a mold assembly to hold said body in position thereon with said base in heat exchange relation with said mold assembly for the flow of molten pastics material from such assembly, through said nozzle tip member and into a die cavity, and wherein said outer shell is formed of a material having a lower thermal conductivity than that from which said body is formed and, support means formed integrally with said outer shell for supporting said nozzle tip member.
