PURPOSE: A vinyl molding die for a vinyl air bubble sheet is provided to be used in a narrow place and to minimize power energy loss by extruding two vinyl films at the same time. CONSTITUTION: A vinyl molding die for a vinyl air bubble sheet forms an inlet channel(21a) connected to an extruder(11) inside a body(21) and forms a forward and a rear branch channel(21b,21c) in the lower portion of the inlet channel. The forward and the rear branch channel form a forward and a rear extruding channel(21d,21e) in the length direction of the body. The forward and the rear extruding channel form a forward and a rear outlet channel(21f,21g) to extrude the certain thickness of a vinyl film. The body installs a heater(24) outside and molten material adjusters(22,23) are placed in the forward and the rear branch channel to adjust the inlet amount of the vinyl film. The rear outlet channel is a little more downward than the forward outlet channel.
