Pressurizing device and vulcanizing machine

The invention belongs to the technical field of vulcanizing equipment, and discloses a pressurizing device and a vulcanizing machine, the pressurizing device is used for providing mold clamping force for a mold, and the pressurizing device comprises a base, a plurality of lower pull rods, a plurality of upper pull rods, a cross beam and a nitrogen supply assembly. According to the pressurizing device provided by the invention, the pressure is applied to the upper side of the mold through the moving part, so that the mold closing force is provided for the mold, and compared with a mode of applying pressure to the lower side of the mold upwards by adopting a stress application oil cylinder in the prior art, the gravity of the mold and related parts does not need to be overcome, so that the performance requirement on the parts for providing the pressure can be reduced; and the use cost can be reduced. According to the pressurizing device, driving force is provided through the nitrogen supply assembly, a traditio
