Abstract
A vulcanizing apparatus having penetrating passages connected and communicated with a jacket portion of a mold member. An upper open end portion of one of the penetrating passages is connected to a steam inlet pipe while an upper open end portion of the other penetrating passage is connected to a steam outlet pipe. The connections and communications of the jacket portion with the steam inlet and outlet pipes can be simultaneously and efficiently completed in a single operation. Inner tubes are slidably disposed along the penetrating passages and pressed against the connecting surface of the mold, and appropriate pressure is applied on the seal packing member on the connecting surface independent from the clamping force of the upper mold in order to ensure reliable sealing.
