The invention relates to an upper die core structure equipped with an inner die core. The upper die core structure equipped with the inner die core comprises an upper die core, the inner die core anda die cavity groove, wherein the inner die core is embedded into the middle part of the upper end surface of the upper die core; the die cavity groove is formed in the middle part of the inner die core; the side edge of the inner die core is higher than the lower end surface of the upper die core and forms a boundary side edge; the front end of the inner die core is rectangular and penetrates thefront side of the upper die core; the rear left corner of the inner die core is of a gap structure; the rear left corner of the die cavity groove is arranged in the upper end surface of the upper diecore; and the front part of the upper die core is vertically equipped with a sprue bush which penetrates the front parts of the upper die core and the inner die core. The upper die core structure equipped with the inner die core has the characteristics that the die cost is decreased; the height of two core pull-out oil cylinders is controlled, so that the two oil cylinders cannot interfere each other; the upper oil cylinder and the lower oil cylinder are capable of continuously pulling out cores, and thus the product production efficiency and quality can be improved.
