    • A breach lock mechanism in a tire vulcanizing machine for clamping upper and lower metal molds under pressure is improved so as to reduce a number or parts, simplify a structure and lower a cost. The tire vulcanizing machine comprises a lower metal mold supported on a base, an upper metal mold supported from a bolster and adapted to be placed on the lower metal mold, an upper ring rotatably fitted around an outer circumferential portion of the bolster and having claws at its lower end, a lower ring supported from the base in a vertically movable manner and having claws at its upper end, first drive means for rotating the upper ring, and second drive means for vertically moving the lower ring. The claws of the upper ring and the claws of the upper ring are adapted to be engaged with or disengaged from each other as a result of rotation of the upper ring, and the upper and lower metal molds are pressurized by lowering the lower ring when the claws of the upper ring and the claws of the lower ring are engaged with each other. Preferably, either or both of the claws of the upper ring and the claws of the lower ring are formed at a plurality of levels so that the engaging position between the upper and lower rings can be adjusted depending upon a total height of the upper and lower metal molds.
    • 用于在压力下夹紧上下金属模具的轮胎硫化机中的破裂锁定机构被改善,以减少数量或部件,简化结构并降低成本。 轮胎硫化机包括支撑在基座上的下金属模具,从垫子支撑并适于放置在下金属模具上的上金属模具,上环,其可旋转地装配在所述摇枕的外圆周部分上并且具有爪 其下端,以可垂直移动的方式从底座支撑的下环,并且在其上端具有爪,用于旋转上环的第一驱动装置和用于垂直移动下环的第二驱动装置。 上环的爪和上环的爪适合于由于上环的旋转而彼此接合或分离,并且当上环和下金属模通过下环时,通过降低下环来加压 上环的爪和下环的爪彼此接合。 优选地,上环的爪和下环的爪中的任一个或两个都形成为多个水平,使得可以根据上下的总高度来调节上下环之间的接合位置 金属模具。

    • The known tire vulcanizing machine of the type in which upper and lower bolsters are disposed within a frame, upper and lower metal molds are respectively fixedly secured to the upper and lower bolsters, and a press mechanism for bringing the upper and lower metal molds into tight contact with each other under a pressure is disposed between the frame and either one of the bolsters, is improved so that a green tire loaded in the machine can be visually inspected up until just before the upper and lower metal molds come into tight contact with each other. In one preferred embodiment, a vertically movable pressure-receiving plate having a polygonal shape is rotatable between short-sized position in which it can vertically pass through a space between upper beams and a long-sized position in which it cannot vertically pass through the same. A rotary drive is provided for rotating the pressure-receiving plate about its center. In another preferred embodiment, a cylindrical body is provided on the upper bolster, an adjust screw is threadedly engaged with the cylindrical body, and a pressure-receiving plate having a polygonal shape is coupled to the adjust screw via guide rods. In both embodiments, a clearance between the pressure-receiving plate and the upper beams is made adjustable.
    • 已知的轮胎硫化机,其中上,下垫板配置在框架内,上下金属模具分别牢固地固定在上下垫片上,以及用于使上金属模具和下金属模具紧固的压力机构 在框架和任一个垫圈之间设置彼此接触的压力被改善,使得装载在机器中的生胎可以被目视检查,直到上下金属模与每个之间紧密接触 其他。 在一个优选实施例中,具有多边形形状的可垂直移动的受压板可在短尺寸位置之间旋转,在该位置中,垂直方向可垂直通过上梁之间的空间和不能垂直穿过其的长尺寸位置 。 提供旋转驱动器用于围绕其中心旋转受压板。 在另一个优选实施例中,在上垫板上设有圆柱体,调节螺丝与圆柱体螺纹接合,并且具有多边形形状的压力接收板通过导杆联接到调节螺钉。 在两个实施例中,压力接收板和上梁之间的间隙是可调节的。
