摘要： Disclosed is a mold attaching/detaching apparatus in a tire vulcanizer, having locking/unlocking means configured so as to perform an engagement and disengagement by utilizing the relative movement between a top plate and bottom plate of the tire vulcanizer in a horizontal direction, and capable of being inexpensively constructed by simplifying the structure and operation of the locking/unlocking means. In the tire vulcanizer configured so that a segmental mold 3 is held between the top plate 1 and the bottom plate 2 to perform vulcanization, and opened and closed while expanding and contracting the segments by raising and lowering the top plate and operating an expansion/contraction device 4, in an engaged state of the locking/unlocking means 50 and 61, the locking/unlocking means is engaged in a state where the center of the top plate and the center of the bottom plate coincide with each other at a vulcanizing position M by the relative movement between the top plate and the bottom plate in the horizontal direction, and is disengaged at an offset position N shifted from the vulcanizing position in the horizontal direction.

摘要： With a split-type vulcanizing mold, a proper clamping force of the mold is obtained without carrying out shim adjustment. A lower washer (16), disc springs (17), and an upper washer (18) are inserted into each of a plurality of cylindrical holes (15) defined on the circumference of a spacer ring (14). A spacer ring (14) provides an outer ring (8) with a pre-load so as to be tightened up by a bolt (12), so that the outer ring (8) can be smoothly moved without backlash in the axial direction thereof all the time. Selection is made on the disc springs (17) having a load such that a proper clamping force is obtained when a deflection of the disc springs (17) is equivalent to half a deflection at the time of the maximum load of the disc springs (17), and regardless of whether variation in dimensions, at the time of fabricating the mold, is on the plus side or minus side, the variation in dimensions is absorbed to thereby clamp the respective sector molds (6) with a proper clamping force. As the sector molds (6) are caused to undergo reduction in diameter, the spacer ring (14) is pushed down by the bolster plate (9) to thereby descend, causing the disc springs (17) to undergo gradual deflection, so that the clamping force applied to the sector molds (6) is increased.

摘要： The present invention differs fundamentally from prior art because it provides for machining a substantial number of relatively thin annular tooling plates (10), fitting them together side-by-side in two opposed mold sides, and engraving the tread pattern into the interior face of the assembled plates in two or more complementary mold parts to form a unique tire mold (12). In one form of the disclosed construction two halves are built up and internally engraved to form a two-piece clamshell mold. This building up of annular plates (10) applies also to the construction of segmented molds, wherein there are multiple complementary mold sections which are joined to provide a complete circumferential mold. Thus, the invention applies to both two-piece clamshell molds and segmented molds. The invention encompasses an all engraved mold and all venting (22) in the circumferential direction.

摘要： An apparatus for transferring heat into a product, such as a tire, formed at least in part by molding is provided. The apparatus includes a mold that has a central axis with a forming surface disposed radially outward from the central axis. A heating conduit is included and is at least partially located radially outward from the forming surface of the mold. The heating conduit is configured for use with a gas, such as saturated steam, in order to effect heat transfer to the forming surface of the mold. The heating conduit extends helically with respect to the central axis in order to allow condensation formed in the heating conduit to be drained therefrom via the force of gravity. A drainage connector may be in communication with the exit of the heating conduit and have a lower longitudinal axis than the heating conduit to allow condensation to drain more easily therefrom.
