The invention discloses a precise progressive die for forming of plastic-embedded reeds. The precise progressive die comprises a base (1), a lower cushion plate (2) and an upper cushion plate (3). A female die insert A (4) is arranged on the portion, located at one end of the upper cushion plate (3), inside the upper cushion plate (3). The lower end portion of the female die insert A (4) is connected with a pressing head (5). A cavity (6) is formed in the lower cushion plate (2). A protruding rod (7) located under the pressing head (5) is arranged in the cavity (6). A cylinder (8) is fixedly installed at the other end of the upper cushion plate (3). A female die insert B (11) is arranged on the top of the lower cushion plate (2). The top of the female die insert B (11) is connected with an inclined wedge B (12). The precise progressive die has the beneficial effects that the structure is compact, the production efficiency is improved, the labor intensity of workers is lowered, operation is easy, and the machining precision is improved.
