Multi-functional blowing shoe mold

The invention in particular relates to a multi-functional blowing shoe mold, and belongs to the technical field of a shoe making mold. The multi-functional blowing shoe mold comprises mold frames that are opened or closed horizontally, wherein air passages are arranged in the mold frames; a bed die is installed in the middle of each mold frame; a shoe tree is positioned above the bed die and corresponds to the bed die in shape and structure; a feed port is formed in the root part of the bed die, wherein a constant-pressure air cabin is arranged at one side of the mold frame; and the bottom of the shoe tree and the bed die form a sole forming cavity that is communicated with the constant-pressure air cabin by the air passages. The multi-functional blowing shoe mold disclosed by the invention ensures that the bottom surface of a sole has high molecular density and good wear resistance, each middle layer has low density, is soft and has good elasticity, raw materials are saved, and the sole has long service life
