Description

子午线轮胎活络模具胎侧板 技术领域
本发明涉及一种子午线轮胎活络模具胎侧板， 具体地说是一种其工作面镶嵌有同心圆环 的子午线轮胎活络模具胎侧板。
背景技术
子午线轮胎的外轮廓是由活络模具中的花纹圈与组合在花紋圈上下两侧的胎侧板模压成 形的。 花紋圈由若干个花纹块沿圆周分布形成， 花紋块的内表面带有花紋， 能够模压出轮胎 的胎冠花紋。 胎侧板用于模压轮胎胎侧的形状、 商标、 图案和文字标识。 通常情况下， 除了 对胎侧板的形状、 尺寸和工作面 （即模压轮胎胎侧的表面， 下同）光洁度有较高要求外， 还 要求胎侧板便于制造、 更换胎侧商标、 图案和文字标识容易且排气性能良好等。
轮胎工厂往往需要在同一副模具上硫化出相同规格但带有不同商标、 图案和文字标识的 轮胎。 这就需要在模具胎侧板工作面上设置活块， 再把不同的商标、 图案和文字标识刻在多 套活块上， 更换活块就能硫化出同规格但不同商标、 图案和文字标识的轮胎。 活块的形状一 般设计成一段圆弧。 与活块相对应的胎侧板工作面上设置圆弧形凹槽， 活块固定安装在凹槽 内。 一付侧板上通常要设置不同大小和不同位置的多个活块， 对应上述不同大小和不同位置 的多个活块在胎侧板工作面上的相应位置要加工出同样大小和数量的圆弧形凹槽。 这种结构 的问题是， 对活块和凹槽的配合要求相当严格， 否则就要在配合处出现缝隙， 使硫化出的轮 胎胎侧留有凸起的胶片。 为了保证不同大小和不同位置的多个活块与相应大小和位置的圆弧 形凹槽的精密配合并有互换性， 需要用高精密的加工中心进行铣削加工， 导致胎侧板制造难 度加大， 提高了制造成本。
硫化轮胎时， 活络模具在合模过程中要把胎胚与模腔之间的气体排出， 这些气体一部分 存在于胎冠部位， 另一部分存在于两边的胎侧部位。 要把存在于两边胎侧部位的气体排出， 长期以来的办法是在胎侧板上设置排气孔， 但是排气孔在排出气体的同时也有一些橡胶随之 流出， 在硫化出的轮胎胎侧表面形成很多小胶柱。设置排气孔的胎侧板存在以下问题； 1、硫 化出的轮胎外观不美观， 轮胎出厂前需要对这些小胶柱进行修剪， 浪费人力， 而且修剪后还 会在轮胎表面留下明显的痕迹； 2、 修剪下来的胶柱只能作为废料处理， 浪费橡胶等原材料； 3、排气孔容易堵塞， 为了保证硫化正常进行， 要定期停产对排气孔进行疏通， 降低了轮胎的 生产效率。 另外一种排气方法是先在胎侧板的工作面上钻出一些台阶孔， 台阶孔的细孔部分 沟通胎侧板的另一面（非工作面， 下同）， 再 ί主工作面上的粗孔中塞入排气柱（一种带有微孔 的材料），硫化时轮胎胎侧与侧板之间的气体从排气柱中的微孔中排出。这种排气方法的好处 是不会在轮胎侧面留下胶柱， 但疏松的微孔材料会在轮胎胎侧表面留下斑痕而影响外观， 并 且微孔材料的排气量较小， 为了使轮胎胎侧与侧板之间的气体充分排出， 就要增多台阶孔的 个数， 这不但常常会与商标、 图案和文字标识的布局发生矛盾， 而且会在轮胎胎侧表面留下 更多的斑痕。
除上述问题之外， 现有结构的胎侧板不同大小和不同位置的多个活块在胎侧板工作面上 的布置经常会与排气孔或排气柱的布置发生干涉。
发明内容
本发明的目的在于克服现有的轮胎模具胎侧板存在的上述缺陷， 提出了一种新结构的子 午线轮胎活络模具胎侧板， 其制造简单且易于更换胎侧商标、 图案和文字标识， 在不设置排 气孔或排气柱的情况下仍具有较好的排气功能， 另外不存在不同大小和不同位置的多个活块 在胎侧板工作面上的布置与排气孔或排气柱的布置发生干涉的问题。
本发明是采用以下技术方案实现的： 一种子午线轮胎活络模具胎侧板， 包括基板， 其中， 所述基板的工作面上镶嵌有不少于一个的同心圆环， 同心圆环的表面与基板的表面共同构成 胎侧板模压轮胎胎侧形状的表面， 基板与同心圆环之间和各相邻的同心圆环之间沿半径方向 均设有环型缝隙。 胎侧商标、 图案和文字标识可全部或部分刻在同心圆环上。
本发明中， 所述的基板工作面设有至少一个环形凹槽， 同心圆环镶嵌在环形凹槽内。 所 述的环形凹槽之间的间距为 0〜50醒。 同一片胎侧板可以对应有一套或一套以上的同心圆环， 每一套中至少包括一个同心圆环， 且各套均可互换性地安装在基板的凹槽内。 需要更换胎侧 商标、 图案和文字标识时， 可将一套同心圆环换成另一套同心圆环， 每套同心圆环中圆环的 个数一般根据轮胎模具的尺寸和胎侧商标、 图案和文字标识的排列情况来确定。
基板与同心圆环之间和各相邻的同心圆环之间沿半径方向均设置 0. 02〜0. 08麵 的环型 缝隙， 该缝隙能够起到排气作用， 同时保证胶料不会从中流出。 在与所述的环型缝隙相对应 处的基板上设有环形集气槽， 该环形集气槽通过其底部的若干个通孔与胎侧板的非工作面相 连通。 在基板的一个环形凹槽内既可以设置一个同心圆环， 也可以设置多个同心圆环。 所述 的同心圆环的厚度为 20〜30腿， 其材料与基板材料相同， 一般为钢环。 硫化合模时， 胎胚侧 面与胎侧板之间的气体首先通过基板、 同心圆环之间的环型缝隙进入基板的环形集气槽内， 然后沿着环形集气槽底部与胎侧板非工作面之间设置的若干个通孔从模具中排出。
该种结构胎侧板的加工方法是， 先将基板的环形凹槽与同心圆环相互的配合面在车床上 加工好， 再把同心圆环与基板进行装配并用螺钉固定， 然后在车床上一次性加工出胎侧板的 工作面。 由于是在车床上加工出基板凹槽和同心圆环的精密配合面， 所以比在高精度的铣削 加工中心上加工容易， 效率高， 大大降低了胎侧板的制造成本。 本发明的有益效果是： 该结构的子午线轮胎活络模具胎侧板由带环形凹槽的基板和不少 于一个的同心圆环组成， 同心圆环镶嵌在基板的环形凹槽中， 由固定螺钉从非工作面一侧与 基板固定在一起， 与现有的活络模具胎侧板相比， （1 ) 该结构的胎侧板容易制造； （2 ) 易于 更换胎侧商标、 图案和文字标识； （3 ) 既能够保证将模具中的气体充分排出， 又不会在硫化 后的轮胎胎侧表面上形成胶柱或斑痕， 使得硫化成型后的轮胎外形整洁美观； （4 ) 无需对胶 柱进行修剪， 节省了人力和胶料； （5 ) 不会存在排气孔堵塞问题， 提高了轮胎的生产效率；
( 6 )不存在不同大小和不同位置的多个活块在胎侧板工作面上的布置与排气孔或排气柱的布 置发生干涉的问题。
