    • A curing machine for pneumatic tires includes a bladder which is tightly held by upper and lower bladder rings, a vertically movable center post for holding the upper bladder ring, and an outer cylinder arranged on a radially outer side of the center post, for supplying a pressurized heat medium into the interior of a green tire. An upper lock mechanism is associated with the top end portion of the center post and serves to automatically lock the upper bladder ring in place by after the top end portion of the center post has been moved upwards and passed through a center through hole in the upper bladder ring. A lower lock mechanism serves to automatically lock and unlock the lower bladder ring, in which a lock region extending downwards from the lower bladder ring is engaged with, and disengaged from a first lock member secured to the outer cylinder by vertically moving a second lock member in opposite directions. The upper and lower lock mechanisms can be operated simultaneously, so that the exchange of the bladders can be performed highly efficiently, in a simplified and within a minimized time.
    • 一种用于充气轮胎的固化机包括由上下囊圈紧紧地保持的气囊,用于保持上气囊环的可垂直移动的中心柱,以及布置在中心柱的径向外侧上的外筒, 加压的热介质进入生轮胎的内部。 上部锁定机构与中心柱的顶端部分相关联,并且用于通过在中心柱的顶端部分向上移动并穿过上部的中心通孔之后自动将上部气囊环锁定就位 膀胱环 下锁定机构用于自动锁定和解锁下囊状环,其中从下囊状环向下延伸的锁定区域通过垂直移动第二锁定构件而与固定到外筒的第一锁定构件接合并脱离 在相反的方向 上下锁定机构可以同时操作,从而可以在简化的和最小化的时间内高效地执行气囊的交换。

    • A vulcanizing machine for producing pneumatic tires includes an exchangeable segmented mold comprised of tread mold pieces for defining the outer contour of a tire tread portion, and upper and lower side mold members engaged with the tread mold pieces, for defining the outer contours of the sidewall portions. The tread mold pieces are detachably connected to connector segments which are slidably engaged with a container ring so that vertical movement of the container ring causes radial movement of the connector segments relative to the tread mold pieces. After production of tires of a predetermined size has been completed, the mold is removed from the machine by moving the container ring upwards to disconnect the connector segments from the tread mold pieces, and disconnecting the upper side mold member from a top plate of the machine. Another segmented mold for tires of a different size is incorporated into the machine, by placing and centering the mold relative to the machine, moving the container ring downwards to connect the connector segments to the tread mold pieces, and connecting the top plate to the upper side mold member. The mold can be efficiently exchanged with respect to the machine under a high temperature condition, thereby improving the manufacturing productivity of tires.
    • 一种用于生产充气轮胎的硫化机包括一个可更换的分段模具,其包括用于限定轮胎胎面部分的外轮廓的胎面模具件,以及与胎面模具件接合的上下侧模具构件,用于限定侧壁的外轮廓 部分。 胎面模具可拆卸地连接到与容器环可滑动地接合的连接器部分,使得容器环的垂直运动导致连接器部分相对于胎面模具件的径向移动。 在已经完成了预定尺寸的轮胎的生产之后,通过向上移动容器环从模具中取出模具以将连接器段与胎面模具件断开,并将上侧模具构件与机器的顶板断开 。 通过将模具相对于机器放置和对中而将不同尺寸的轮胎的另一个分段模具并入机器中,向下移动容器环以将连接器部分连接到胎面模具件,并将顶板连接到上部 侧模构件。 可以在高温条件下相对于机器有效地更换模具,从而提高轮胎的制造生产率。
