MOLD CAVITY STRUCTURE

摘要

The invention relates to a mold cavity for the production of hollow molded parts. Said mold cavity forms a molding chamber (5) and comprises a cavity ( 1) whose inner contour matches the outer contour of the molded part that is to be produced in at least some sections thereof, a core (2) whose outer contour matches the inner contour of the molded part that is to be produced in at least some sections thereof, and a supporting ring (3) which at least partially surrounds the core (2) at least when the mold cavity is closed. Sa id supporting ring (3) is provided with an inner cone (9) while the core (2) is provided with a corresponding outer cone (8). Said cones (8, 9) are configur ed such that the inner cone (9) of the supporting ring (3) enters in contact wi th the outer cone (8) of the core (2) at least when the mold cavity is closed. In order to provide a mold cavity or a core and a supporting ring which can easily be adjusted to different molded parts while being easy to produce, neither the inner cone (9) of the supporting ring nor the outer cone (8) of the core (2) is located directly adjacent to the molding chamber (5).
