A pressing device for a vulcanizer mold is provided to prevent occurrence of extruded rubber in vulcanizing a tire and to reduce process time by installing a check valve supplying air selectively to a main or an auxiliary squeezing unit installed in parallel, and checking an air amount necessary in a process of the vulcanizer mold and pressurizing in advance. A pressing device for a vulcanizer mold comprises an air pipe(100) flowing air inside, an air supplying unit(110) supplying air to the pipe, a cross valve(120) opened and closed to flow the air supplied from the air supplying unit selectively, a main squeezing unit(130) pressurizing and storing the air supplied from the cross valve, and an auxiliary squeezing unit(140) pressurizing and storing the air supplied from the cross valve when the main squeezing unit is not in operation. The main squeezing unit comprises a main booster pump(132) compressing air to a certain amount and flowing the air in the pipe, a main tank(134) storing the compressed air flowed from the main booster pump, and a main pressure valve(136) opened and closed to flow the compressed air stored in the main tank selectively.
