Description

[根据细则37.2由ISA制定的发明名称]　一种液压轮胎硫化机 技术领域
本发明属于机械制造技术领域，具体地说，涉及一种液压轮胎硫化机。
背景技术
目前，制造工程轮胎使用的轮胎硫化机，因工程轮胎较大，制造模具大，加热不均匀，导致有加热死角，硫化效果并不好。
其中，CN202174675U，公开了一种液压轮胎硫化机，其结构是：包括上盖、机座和液压缸，机座下部的内腔作为液压缸的缸筒，活塞的下部与机座下部的缸筒相互配合组成液压缸；上盖与机座之间具有锁定装置。上盖上具有用于通入加热介质的第一腔室，活塞上具有用于通入加热介质的第二腔室。机座下部为环形的内腔，环形的内腔作为液压缸的缸筒；活塞的下部为环形圈，环形圈与环形的内腔相互配合。在该专利技术中的上盖即为模具上模，活塞即为模具下模。使用时，向上盖的第一腔室和活塞的第二腔室中通入蒸汽，向中心机构的胶囊和机座的内腔中通入压强相等的高压过热水。胶囊膨胀充满轮胎胚胎的内腔，机座的内腔中的高压过热水驱动活塞向上移动，对模具提供合模力，此时开始对轮胎胚胎进行加热加压硫化。上述技术实现了模具和硫化机的一体化；既可以在上盖和活塞的内表面上直接加工出轮胎的花纹，也可以在上盖与活塞之间的内腔中安装活络模具或者其他模具；具有使用广泛、构造简化、成本降低和操作简单的特点。但是，该技术存在以下问题：其一：由于该技术中用于通入蒸汽的腔室为热板式，分为第一腔室和第二腔室，上盖上具有若干与第一锁定齿对应的第二锁定齿，机座外侧具有与锁定圈对应的环形锁定槽，故上蒸汽腔壁的下端位于第二锁齿的上部，下蒸汽腔壁的上端与环形锁定槽持平，这就造成上盖(模具上模)与活塞(模具下模)连接处、垂直高度上与从环形锁定槽至第二锁齿一致的部位，被排除在第一腔室和第二腔室之外，构成加热死角。加热加压硫化过程中，蒸汽能够包围位于第一、第二腔室内部的模具部分，不能涉及到位于第一、第二腔室外部的模具部分，因此在第一、第二腔室内、外的这两部分模具其加热硫化程度明显不均匀，严重影响硫化机的硫化效果。其二：机座下部为环形的内腔，环形的内腔作为液压缸的缸筒；活塞的下部为环形圈，环形圈与环形的内腔相互配合。其实际上，内腔由下蒸汽腔壁的下端、活塞下部的环形圈、机座与下蒸汽腔壁的下端相平行的部分构成，因此当向机座的内腔中通入高压过热水驱动活塞向上移动时，实际上是高压过热水首先驱动下蒸汽腔壁向上移动，进而驱动与其相连的活塞向上移动。 由于下蒸汽腔壁的水平方向与垂直方向、下蒸汽腔壁与环形圈、机座与下蒸汽腔壁的下端相平行的部分与下蒸汽腔壁和环形圈的连接方式为焊接式，即整个环形内腔为焊接连接，长时间通入高压热水后，易被腐蚀、损坏，进而使高压热水进入硫化的其他空间内如第二腔室内，严重破环轮胎的硫化过程，不能完成硫化。
根据存在的上述问题，发明人改进了该技术，并申请了专利CN201410140003.5，其公开了一种液压轮胎硫化机，其结构是：包括模具上模、模具下模、机座，还包括顶盖，所述模具上模与模具下模密封连接，构成模具；顶盖与机座密封连接，构成外壳；在模具外部与外壳内部之间形成连贯的蒸汽腔室。在顶盖与模具上模采用螺栓固定，在模具上模和模具下模靠近中心机构的两端设置模具密封圈。该技术解决了CN202174675U中的存在加热死角、硫化效果不好，但是，由于密封件易老化，其仍然存在高压热水容易进入蒸汽腔室，导致因加热温度下降造成的轮胎报废的技术问题。
发明内容
为解决上述技术问题，本发明提出了一种结构简单、硫化效果好的液压轮胎硫化机。
本发明的技术方案是：一种液压轮胎硫化机，包括外壳和模具；外壳包括顶盖和机座，顶盖设置于机座上方，两者通过锁定装置连接；模具包括上模和下模，上模和下模密封连接；下模位于机座上方，上模位于顶盖下方，顶盖与上模固定连接；模具外部与外壳内部之间设有闭合的内蒸锅，模具与内蒸锅之间形成的空腔为蒸汽腔室。内蒸锅可以保证蒸汽腔室内保持稳定的温度，从而使模具各部分加热均匀一致，优化硫化效果。
所述内蒸锅底部设有活塞，活塞与内蒸锅为一体式结构，活塞与下模之间形成的空腔为内腔室。
所述机座上设有油缸，油缸包括柱塞和缸筒，缸筒底部设有进油口。
所述机座上设有活塞，活塞与内蒸锅固定连接，活塞与下模之间形成的空腔为内腔室。
所述活塞两端设有活塞密封圈。
所述机座两端分别设置与蒸汽腔室连通的排气孔和进气孔。用于通过高温蒸汽，加热模具。
所述机座两端、排气孔和进气孔下方分别设有排水口和进水口。
所述锁定装置为锁环，锁环上设有第一锁定齿，顶盖上设有与所述第一锁定齿匹配的第二锁定齿；所述锁环底部与机座卡接，锁环上的第一锁定齿与顶盖上的第二锁定齿卡接。
顶盖与上模的固定连接方式优选为通过螺栓固定连接。
使用时，将轮胎胎胚装入模具内，将上模与下模完成合模。将顶盖、上模与内蒸锅通过 螺栓固定，将机座与顶盖通过锁环锁定连接，使锁环上的第一锁定齿与顶盖上对应的第二锁定齿卡接。通过进气孔向模具与内蒸锅之间形成的蒸汽腔室中通入蒸汽，通过进水口向内腔室中通入高压过热水，内腔室中的高压热水驱动模具向上移动，提供合模力。此时，对轮胎胎胚进行加热加压硫化。轮胎胎胚定型硫化后，停止通高压过热水和蒸汽。冷却后，转动锁环使第一锁定齿与顶盖上的第二锁定齿脱离，然后向上移动顶盖和模具上模，打开模具，取出轮胎。
本发明的有益效果在于：
1、本发明在模具与外壳之间形成连贯的蒸汽腔室，消除了现有技术中的加热死角，加热加压硫化过程中，蒸汽能够充满蒸汽腔室，包围模具外部，从而使模具各部分加热均匀一致，优化硫化效果。
1、本发明通过向活塞和下模之间形成的内腔室中通入高压过热水来提供合模力；避免了焊接式的结构，从而起到抗腐蚀、防泄漏的作用，进而避免了高压热水进入蒸汽腔室内，保证了轮胎的硫化过程的顺利完成。
2、本发明通过设置内蒸锅，提高了蒸汽内腔的固定性能和密封性，通过设置活塞密封圈提高了内腔的密封性，有利于硫化过程的顺利进行。
3、本发明通过设置顶盖，并在顶盖与机座之间采用锁定装置连接，构成外壳，省略了上蒸汽腔壁和下蒸汽腔壁，结构简单。
4、本发明能够使模具和硫化机实现一体化；既可以在模具的内表面上直接加工出轮胎的花纹，也可以在模具之间的内腔中安装活络模具或者其他模具；具有使用广泛、构造简化、成本降低和操作简单的特点。
