摘要

Mold system for multicomponent injection molding of toothbrush bases (4) comprises mold halves (1, 1') which enclose a mold cavity (2) into which a first molding component is injected around a premolding (3). A conversion component (6) is then lowered in a T- or L-shaped guide (7) to change the shape of the cavity and allow a second component to be injected.
