BRANCHING CORE-PIN ASSEMBLY, SYSTEM FOR FORMING BRANCHING CHANNELS AND MOLDED|WORK-PIECE

摘要

A core-pin assembly (10,200) composed of a primary core-pin (12) and at least one secondary core-pin (14). The primary core-pin (12) has a primary core-pin body (20) defining at least one element (22) for coupling with a mating end (24) of at least one secondary core- pin (14). The secondary core-pin (14) has a mating end (24) and a secondary core-pin body (28). The mating end (24) is configured to fit with the element (22) defined in the primary core-pin body (20) such that the primary core-pin and the secondary core-pin(s) reversibly join together to form a branching structure. The assembly (10,200) may further include at least one tertiary core-pin (30) and the secondary core-pin body (28) may define at least one element (22) for coupling with a mating end (34) of at least one tertiary core-pin. The mating end (32) of the tertiary core pin (30) is configured to fit with the secondary core-pin body (28) such that the primary core-pin (12), secondary (14) and tertiary core-pin(s) (30) reversibly join together forming a branching structure.
