Abstract: A mold blocking member is described for use in a vent bore of a mold for the manufacture of rubber products. The mold blocking member has a tubular hollow body having a first end and a second end. The second end is preferably chamfered for easy insertion into the mold. The first end has a spring element positioned thereon. A cap is affixed to a flat portion of the spring element. The bottom surface of the cap may optionally include channels.

Abstract: A mold and mold blocking member is provided for use in a vent bore of a mold for the manufacture of rubber products. The mold blocking member has a tubular hollow body having a first end and a second end, wherein the first end has a cap having an outer dimension greater than the diameter of the tubular body, wherein the cap has at least one undercut forming an opening, wherein the opening is positioned to be adjacent the mold surface.

Abstract: A mold blocking member for use in a vent bore of a mold for the manufacture of rubber products is provided. The mold blocking member has a tubular hollow body having a first end and a second end, wherein the first end has a cap with an inner portion surrounded by a recessed annular portion, wherein the inner portion is connected to the recessed annular portion by a sidewall, wherein the sidewall has one or more slots therein. The slots opening has a width dimension in the range of about 0.1 mm to about 0.6 mm and a thickness in the range of about 0.03 mm to about 0.15 mm. It is preferred that the inner portion is flat and recessed with respect to the outer rim of the first end.

Abstract: A blocking member for use in a vent bore in a mold for the manufacture of technical rubber products, in particular to the manufacture of vehicle tires, wherein each blocking member has a tubular hollow body which can be fixed in force-transmitting manner in the respective bore, the hollow body having a sealing part formed thereon in one piece with it. The sealing part has a plate element disposed at the inner side of the mold which is provided in its plate surface with at least one slot opening and the peripheral rim of the plate element projects at least regionally beyond the bore diameter of the associated vent bore and contacts the inner side of the mold.

Abstract: A vulcanization mold is described for the manufacture of technical rubber products comprising a plurality of vent bores in which a blocking member is mounted which consists of a central body and a sealing part coupled to it which together form at least one angled flow path for air to be dissipated, with the central body being fixed in the vent bores, on the one hand, by clamping ribs provided at the central body and, on the other hand, by blocking elements which are formed at spring limbs of the sealing part.

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.
