Abstract
The invention relates to a vulcanization mold for producing rubber goods, especially vehicle tires. The mold has a number of deairing holes into which blocking mechanisms are introduced. The blocking mechanisms ensure, especially by means of the air duct being bent, that the air can be drained without any disadvantageous flash being produced. In a second embodiment, the blocking mechanisms forms a two-part valve with the central body. In this case, the blocking mechanism has an elastically deformable planar area placed on the inside of the mold which acts at least essentially as a seal in conjunction with the central body when impinged upon by the surface of the blank.
