Mold Insert Stack for Use in an Injection Mold and a Coupler Thereof

Abstract

There is disclosed a mold insert stack for use in an injection mold and a coupler thereof. The mold insert stack for use in an injection mold is provided and comprises a core assembly that includes: a core insert that includes: a core body; an inner molding surface that is defined on the core body, the inner molding surface provides, in use, an inner portion of a molding cavity that is shaped to mold a preform; a core-coupler interface that is defined on the core body; a support member that includes: a support body; a support-sliding interface that is defined on the support body; a coupler member that includes: a coupler body; a coupler-core interface that is defined on the coupler body; a coupler-insert interface that is defined on the coupler body; and a complementary sliding interface that is defined on at least one of the coupler body and the core body; the coupler-core interface and the core-coupler interface being configured to cooperate, in use, to mutually locate the coupler body with the core body; the coupler-insert interface being configured to cooperate, in use, with a complementary interface defined on a further mold insert; the support-sliding interface and the complementary sliding interface being configured to cooperate, in use, to establish a slidable coupling that is able to accommodate, in use, a lateral move (S1) between the support-sliding interface and the complementary sliding interface and connect a load path between the support body with at least one of the core body with the coupler body.
