Key statement: Provided are: a tire mold including a bead portion molding surface
for molding the bead portion of the tire, the bead portion molding surface
having a ridge molding part including a recessed groove extending in the mold radial direction, the ridge molding part being formed in a flange contact portion molding region for molding a rim-flange contact portion of the tire; and a pneumatic tire, in which a bead filler has the tire radial direction outer end positioned more inward in the tire radial direction relative to the rim line position, and a ridge forming portion including a ridge extending in the tire radial direction is formed on the outer surface of the bead portion, the ridge forming portion being positioned in the rim flange contact portion.
For efficient process control, the mold must be equipped with thermocouples that are close to the molding surface
to monitor temperature.
The local texture of the molding surface
of the cavity and also the processing conditions affected the gloss of the corresponding surface of the molded parts.
That will give us uniform heat transfer tram the molding surface
. The copper layer will vary in thickness across the mold.
This torus shape keeps the channels 3.18 mm from the molding surface
along the entire perimeter of the cavity.
A stencil plate for molding the projecting marking is made of a thin metallic plate whose thickness is 0.2 to 0.8 mm and mounted in a recess formed in a sidewall molding surface
of the tire vulcanization mold.
This molding element has a molding surface
adapted to mold part of the tire tread surface and a blade adapted to mold a sipe or a groove in the tread.
The tool is enclosed in a box of wood or other material so that the molding surface
can be entirely covered with loose plastic powder or granules.
The molding element having a molding surface
intended to mold part of the tire tread surface and a blade intended to mold a sipe or a groove in the tread.
The mold element comprises a molding surface
able to mold all or part of the tread surface of this tread.
Thereafter, the molten metal is poured onto the surface of the gypsum mold in such a way that the tubular body is buried in the mold while the slit is exposed on a tire molding surface
of the mold.
Key statement: A tire vulcanization mold cleaning method for cleaning a molding surface
of a sector of the tire vulcanization mold for molding a tread portion of a pneumatic tire by using plasma created in an atmosphere of a reaction gas which chemically reacts with dirt attached to the molding surface
of the sector.
