Molding mechanism for the in-mold formation and assembly of an actuator- overcap and an insert nozzle and method for using such mechanism

摘要

A molding mechanism and method of using that mechanism for simultaneously forming, by injection molding, two molded parts intended to be interference fit together and then, while the two molded parts are still within the molding mechanism, repositioning them and fitting them together. The sequenced interplay of the moving parts of the molding mechanism which accomplishes this process may be controlled by either a two-part or a single-part camming mechanism. The two molded parts may be an actuator-overcap and a spray nozzle insert.
