Abstract

A dipping mold comprises a shell and a nozzle borne on the shell. The shell comprises an inner processing chamber and extruding and pulling opening holes. The nozzle comprises an opening. The opening is provided with an inlet end, an outlet end and a center axis. The inlet end is communicated with the processing chamber through the extruding and pulling opening holes. The dipping mold is characterized in that the opening comprises a first conical part adjacent to the inlet end, a first straight part arranged on the downstream part of the first conical part, a second conical part arranged on the downstream part of the first straight part, and a second straight part which is arranged on the downstream part of the second conical part and is adjacent to the outlet end.
