Internal mixing type spraying device

The utility model relates to an internal mixing type spraying device which is mainly applied to automatic forging equipment. The internal mixing type spraying device comprises a support 1, an atomizing unit 2 used for atomizing a release agent and a cavity 3 used for flowing of the atomized release agent are arranged in the support 1, an inlet of the atomizing unit 2 is communicated with a compressed air pipeline 7 and a release agent pipeline 8 in the support 1, and an outlet of the atomizing unit 2 is communicated with the cavity 3 arranged in the support 1. One end of the support 1 is connected with a spraying plate 4, an atomizing pipeline 5 is arranged in the spraying plate 4, a plurality of small holes 6 are formed in the spraying plate 4, an inlet of the atomizing pipeline 5 is communicated with the cavity 3, and an outlet of the atomizing pipeline 5 is communicated with the small holes 6. The internal mixing type spraying device is simple in structure, low in cost and good in atomization performance,
