下面结合附图详细说明本发明的优选实施方式。
实施例 1
如图 1所示， 本实施例中的轮胎硫化机包括机架 1、 横梁机构以 及模型机构（模型机构图中未示出）， 机架 1包括多根支撑柱 11， 支 撑柱 11 的数量一般应根据具体结构设计进行调整， 如拉杆数量为两 根， 则支撑柱 11 可以设置为两根， 以足够对部件进行支撑； 横梁机 构包括上横梁 21和下横梁 22， 下横梁 22都与机架 1连接， 具体为水 平架设于机架 1的支撑柱 11之间， 上横梁 21通过开合模导向系统与 下横梁 22导向连接（图中未示出） ； 模型机构设置于上述上横梁 21 和下横梁 22之间， 其上下端部分别与上横梁 21和下横梁 22 固定连 接； 本实施例中的轮胎硫化机还包括拉杆机构， 该拉杆机构包括四组 拉杆以及与拉杆数量相等的锁模机构 4和液压油缸 6; 拉杆包括可拆 卸连接的上拉杆 31和下拉杆 32 , 上拉杆 31与上横梁 21固定连接， 下拉杆 32穿过下横梁 22和液压油缸 6， 锁模机构 4固定连接于下拉 杆 32的下端部或中部， 每个锁模机构 4包括一个驱动装置 41、 一个 摆杆 45、 多个连接件以及一个球头销座 44， 上述驱动装置 41、 摆杆 45、 连接件以及球头销座 44相互进行连接， 拉杆的数量可以为三才艮 或者多于三根来进行设置。如图 4所示，上述的轮胎硫化机还包括上、 下拉杆连接位置检测装置， 包括碰块 51和极限开关 52， 上述碰块 51 设置于上述上拉杆上， 上述极限开关 52设置于上述下拉杆上并电连 接至外部控制系统； 上拉杆 31与下拉杆 32为间隙配合， 轴向和侧边 都留出了一定的间隙（如图 1所示）， 以为开关调整的误差作出预留， 使得调整和松闭锁动作非常可靠； 外部控制系统可以为计算机等设 备， 以实现自动化控制。
上述的模型机构是由上半模和下半模组成， 一般被称为上模和下 模， 上模被固定在上横梁 21上， 下模被固定在下横梁 22上。
上述的拉杆机构还可以包括至少一个连杆 43， 该连杆 43连接于 两个摆杆 45之间， 这样就可以把原先多个分设于多个下拉杆 32上的 锁模机构练成一整体， 可以省去另外几个锁模机构上的驱动装置 41， 仅以一边的驱动装置 41提供驱动力， 再通过连杆 43的作用驱动另一 边的锁模机构。 连杆 43的数量应该^ ^据下拉杆 32上的摆杆 45和相 应的使用需要来决定，例如本实施例中设置了四根下拉杆 32 , 其上也 设置有四个摆杆 45，相邻两个摆杆 45之间通过连杆 43做连接， 则可 以设置三根连杆 43， 其中两个摆杆 45之间空出不设连杆 43， 在空出 的这两个摆杆 45中的其中一个摆杆 45通过驱动装置 41施加驱动力， 再通过连杆 43的作用驱动其他几个摆杆 45。 当只需要连接两个摆杆 45的情况下， 则应该设置一个。
如图 1所示， 上述的连杆 43还设计成折弯形状， 以为其他部件 的安装腾出空间， 相对于直杆更为节省空间。
如图 2所示， 上述的四根拉杆沿着模型机构的外围均匀分布， 这 样的排布可以保证模型受力均匀。
如图 1-2所示， 上拉杆 31的下端部设有多个相对于上拉杆 31的 轴心线均匀分布的凸块 35，该凸块 35在上拉杆 31的下端部分别横向 延伸形成连接头 33， 下拉杆 32的上端部对应上拉杆 31的凸块 35设 有多个相对于下拉杆 32的轴心线均匀分布的凹槽 36，该凹槽 36在下 拉杆 32的上端部的内部横向延伸形成连接槽 34,上拉杆 31和下拉杆 32通过上述凸块 35和凹槽 36的配合，即连接头 33和连接槽 34的配 合进行可拆卸连接， 其中连接槽 34在轴向和四周都比连接头 33要略 大， 为准确可靠进行松闭锁提供保障。
如图 1所示， 上述的液压油缸 6的活塞杆 61的内部为空心结构， 活塞杆 61与下拉杆 32进行套接并轴向固定， 该液压油缸 6的缸筒固 定连接在下横梁 22 的下平面上。 保留下拉杆转动自由度， 用以实现 与所述上、 下拉杆的断开和连接（松闭锁） 。
如图 2-3所示， 上述的锁模机构 4连接于下拉杆 32的下端部或 者中部， 同时上述锁模机构 4的一端部还连接至上述支撑柱 11或上 述下横梁 22。
如图 3所示， 四个摆杆 45分别与四个下拉杆 32的底部或中部固 定连接， 各个摆杆 45还与球头销座 44固定连接。 也可以采用驱动装 置 41直接驱动摆杆 45的形式实现同样功能， 相应的， 驱动装置 41 两端需要采用球头销轴连接， 每根拉杆需配置一组驱动装置 41。
如图 1-3所示， 上述的连接件包括销接件 422和铰接件 421 ; 球 头销座 44包括销座 442以及设置上述销座 442内的球头 441，与上述 销座 442的开口相对的另一端部与摆件 45固定连接。
如图 1-3所示， 上述的驱动装置 41的一端部与上述支撑柱 11通 过铰接件 441转动连接， 具体为通过角支座 46进行连接， 角支座 46 与锁模机构 4之间又通过铰接件 441进行转动连接， 驱动装置 41的 另一端部即活塞杆 411通过插入上述球头销座 44的球头 441与上述 球头销座 44连接。
如图 1-3所示， 上述的连杆 43的一端部与一摆杆 45转动连接， 另一端部与一销接件 422连接， 上述销接件 422还与另一摆杆 45转 动连接。
上述的驱动装置 41优选地可采用气虹 41进行实施。
上述的固定连接方式可以采用螺接等固定连接方式， 转动连接方 式可以采用铰接等固转动连接方式。
由于轮胎硫化机一般由两套硫化机单元并排构成， 因此可以将驱 动装 41连接于两套硫化机单元之间共用的支撑柱 11上， 利用一端活 塞杆的运动而带来的回力来带动另外一边的运动， 这样只需要使用一 个驱动装置 41来对两边的锁模机构 4进行驱动。
实施例 2
其他与实施例 1所述内容相同， 不同之处在于： 上拉杆 31的下 端部设有多个相对于上拉杆 31 的轴心线均句分布的凹槽， 该凹槽在 上拉杆 31的下端部的内部分别横向延伸形成连接槽， 下拉杆 32的上 端部对应上拉杆 31的凹槽设有多个相对于下拉杆 32的轴心线均匀分 布的凸块，该凸块在下拉杆 32的上端部横向延伸形成连接槽 34,其中 连接槽 34在轴向和四周同样都比连接头 33要略大， 为松锁的精确提 供保障。
下面介绍本发明的工作原理：
施加锁模力时， 套设于下拉杆 32上的液压油缸 6提供驱动力给 予下拉杆 32， 已与下拉杆 32连接的上拉杆 31， 带动上横梁 21对模 型向下施加锁模力； 锁模机构 4的驱动装置 41向前推动与其连接的 球头销座 44， 由于活塞杆 411插入于球头 441中， 通过球头 441的作 用即可以实现锁模机构 4 自适应功能， 从而带动下拉杆的旋转， 从而 实现上、 下拉杆间的连接或松开。 只有在上下拉杆连接状态下才可以 施加锁模力。 锁模机构 4 上还设置有多个铰接件和 /或销接件， 可以 自适应下拉杆端由于施加锁模力时的上下运动； 设置于上拉杆上的碰 块与设置于下拉杆上的极限开关配合进行开关的开合， 通过该开关的 作用来对上、 下拉杆的连接间隙进行判断。
采用以上技术方案的有益效果在于：
1.本发明将加压托板去掉， 而将液压油缸直接套设于下拉杆上， 液压油缸的驱动力直接通过下拉杆驱动上拉杆和上横梁达到施加锁 模力的目的， 相较于传统的安装加压托板的轮胎硫化机， 重量得到了 减轻， 零件精度要求得到降低， 制造成本也得到节约；
2.本发明在下拉杆的下端部或中部设置连接了锁模机构， 该锁模 机构包括相互连接的驱动装置、 连接件、 连杆以及球头销座， 通过连 接件、 连杆以及球头销座的作用使得连杆可以在 XYZ三轴上自适应下 拉杆的上下运动， 从而进一步地提高上下拉杆松闭锁的可靠性； 3.本发明进一步的方案中， 还设置了上、 下拉杆连接检测装置， 包括碰块和极限开关， 碰块设置于上拉杆上， 极限开关设置于下拉杆 上， 通过该开关的作用来对上、 下拉杆的连接间隙进行自适应调节， 从而为调模增加一自适应调模的功能。
以上所述的仅是本发明的优选实施方式， 应当指出， 对于本领域 的普通技术人员来说， 在不脱离本发明创造构思的前提下， 还可以做 出若千变形和改进， 这些都属于本发明的保护范围。
