    • An apparatus and method for vulcanizing a tire using a pair of split dies which form a tire receiving space between them when the dies are closed. The dies include sealing surfaces within the space and adjacent the axially outer surfaces of the tire beads. The apparatus is mounted within the space and within the inner diameter of the tire, and includes holding means which are radially movable into and out of engagement with the tire beads. The apparatus further includes extruding means which operate in association with the movement of the dies when opening and closing, for moving the holding means toward and away from the tire beads. When the dies are closed, the extruding means move the holding means to press the beads tightly against the sealing surfaces. The interior of the tire is then directly heated and pressurized.
    • 一种用于硫化轮胎的装置和方法,所述一对分割模在模具闭合时在它们之间形成轮胎容纳空间。 模具包括在该空间内并且邻近轮胎胎圈的轴向外表面的密封表面。 该装置安装在该空间内并在轮胎的内径内,并且包括能够径向移动进入和离开轮胎胎圈的保持装置。 该装置还包括挤压装置,其与打开和关闭时的模具的运动相关联地操作,用于使保持装置朝向和远离轮胎珠移动。 当模具关闭时,挤出装置移动保持装置以将珠子紧紧地压靠在密封表面上。 然后将轮胎的内部直接加热和加压。
