Multi-cavity extrusion die

The utility model relates to a multi-cavity extrusion die in the technical field of forming dies, which comprises a screw connecting plate, a splitter plate, a supporting plate and a pipe wall thickness adjusting sheet which are sequentially arranged along the flowing direction of rubber materials, and the tail end of an inclined hole is communicated with a forming flow guide die core plate. The two sides of the top face of the supporting plate are each provided with three positioning holes in threaded connection with the screws, a transverse runner communicating with the bottom end of the inclined hole is formed in the center of the upper surface of the forming flow guide mold core plate, the bottom end of the inclined hole is attached to an opening of the transverse runner, and three branch runners are sequentially formed in the opening of the transverse runner from front to back. And glue injection openings are formed in the two ends of each sub-runner. Through the forming flow guide mold core plate which
