PURPOSE: A 2-cavity mold for large size frame for injection molding is provided to simplify a molded product and improve the productivity of the product by shortening a cycle time. CONSTITUTION: A mold part(10) includes two cavities(12a,12b) formed toward the front side of the mold part in the same direction. A hot runner part(11) roles as the path for injecting a resin into the cavities, and is formed in an assembly shape in which a main block(15) is combined with a sub block(16). Plural nozzles(18) are formed between the hot runner part and the mold part. A main resin path is formed in the main block to induce the smooth flow of the resin.
