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.
Claims15
A blocking member for use in a vent bores of a mold for the manufacture of rubber products, the mold having a wall defining at least a part of a mold cavity and having an inner side adjacent said mold cavity and a vent bore extending through said wall away from said inner side, said blocking member comprising:
- a tubular hollow body a sealing part formed on said hollow body in one piece with it, said sealing part having a plate element, said plate element having a plate surface, at least one slot opening formed in said plate surface and a peripheral rim, said peripheral rim projecting radially in use at least regionally beyond said associated vent bore and contacting said inner side.
A blocking member comprising:
- a tubular hollow body being formed by two half shells which include longitudinal slots between them, a sealing part formed on said hollow body in one piece with it, said sealing part having a plate element, said plate element having a plate surface and said plate element being carried by connecting lugs which start from the half shells, which lie diametrically opposite to one another and merge into said plate surface between cuts provided in a rim of said plate element.
Vulcanization mold for the manufacture of technical rubber products, in particular for the manufacture of vehicle tires, having a plurality of vent bores extending from an inner side of said mold through a side wall thereof and a respective blocking member mounted in each of said vent bores and adapted to at least substantially block the penetration of a molding composition into the associated vent bore and to simultaneously enable an extraction of air, each said blocking member having a tubular hollow body adapted to be fixed in use in force-transmitting manner in said vent bore, and a sealing part formed on said hollow body in one piece with it, said sealing part having a plate element disposed in use at said inner side of the mold, said plate element having a plate surface, at least one slot opening formed in said plate surface and a peripheral rim, said peripheral rim projecting radially in use at least regionally beyond said associated vent bore and contacting said inner side.
A method of venting a mold comprising the steps of:
- placing a blocking member in a vent bore of a mold, the mold having a wall defining at least a part of a mold, cavity and having an inner side adjacent said mold cavity and a vent bore extending through said wall away from said inner side, said blocking member having a tubular hollow body adapted to be fixed in use in force-transmitting manna in said vent bore, and a sealing part formed on said hollow body in one piece with it, said sealing part having a plate element disposed in use at said inner side of the mold, said plate element having a plate surface, at least one slot opening formed in said plate surface and a peripheral rim, said peripheral rim projecting radially in use at least regionally beyond said associated vent bore and contacting said inner side.
