摘要

PURPOSE: A multi-mold, an injection molding system therewith, an injection mold for forming a part of the multi-mold, and a hot mold system of the injection mold are provided to reduce mold and production costs by molding different materials using one multi-mold. CONSTITUTION: A multi-mold(1) comprises a moving unit(10), a fixed unit(20), and a middle part(30). The moving unit comprises a movable mounting plate(11) and a first male mold block(15). The fixed unit comprises a fixed mounting plate(21), a fixed sprue bush(22), and a second male mold block(25). The fixed mounting plate is installed to be opposite to the movable mounting plate. The second male mold block is coupled to the fixed mounting plate. The middle part comprises first and second female mold blocks(31,32) and a first middle sprue bush(42). A first cavity(C1) for molding a first product is formed between the first male and female blocks. A second cavity(C2) for molding a second product is formed between the second male and female blocks.
