通过将熔融材料压入成型模具型腔实现产品成型的成型设备主要包括用于金属成型的压铸机和用于塑料成型的注塑机，通常由合模机构及其液压传动元件、压射机构、电气控制元件等组成。
合模机构是压铸机、注塑机中的主要机构之一，主要由机台、动模板、静模板、尾板、支撑大杠、开合模缸及曲肘、调模机构组成；所述的静模板与机台固定连接，所述的动模板通过开合模缸驱动的机铰在机台导轨上滑动；所述的支撑大杠与所述的机台导轨平行设置，其两端分别位于动模板的前后两侧，并与动模板滑动配合，一端与静模板固定连接，另一端与尾板传动连接。通过开合模缸驱动机铰实现动模板与静模板的分合，从而保证在整个成型过程中型模及其分型面的位置固定；另外，尾板与动模板在调模机构驱动下沿轴向滑动，调节尾板、动模板与静模板之间的最终间距，从而实现对不同厚薄模具的适应。
具体而言，目前压铸机、注塑机最常见的现有合模机构是机铰式或称曲肘式、曲拐式合模机构，它的曲肘均布于尾板与动模板之间。它的合模机构的开合模缸都固定于尾板上，动模板与尾板通过曲肘连接，开合模缸驱动曲肘推动动模板运动，当动模板与静模板完成合模时，曲肘呈伸直状态并机械自锁；其调模机构也安装在尾板上，包括通过调模马达驱动的一个大齿轮、沿大齿轮周向布置的行星齿轮驱动与支撑大杠尾端的调节齿轮螺母实现尾板、动模板及曲肘沿大杠轴向的运动，实现动模板与静模板之间的间距调整。曲肘式合模机构的优点集中体现在曲肘结构上，即开合模速度快、合模实现机械自锁、锁模刚性好等优点。但同时也存在以下缺点，如曲肘各活动关节受力不均衡，各轴销轴套磨损严重，长期使用后相对合模精度大幅度下降。经研究发现，产生上述问题的原因主要是：动模板与静模板之间的平行度、生产厂家安装的模具的平行度、在生产过程中模具出现局部热胀冷缩导致的模具不平行、在加工产品过程中过载胀模造成模板退让不一致的不平行等，造成以上的不平行都会导致曲肘轴销及轴套两者轴线不平行，两轴线不平行导致轴销与轴套产生憋力偏磨转动致轴销轴套快速磨损，甚至轴销承载不 平衡剪切折断。这样下去便会使动模板与静模板平行度误差越来越大甚至合模精度急速下降。当出现上述动模板与静模板的平行度误差值时，制造厂家与使用商家通常采用调整牵拉支撑大杠的方法将尾板、曲肘、动模板调到整体平行于静模板的状态。这样一来动模板与静模板大面是平行了，但反过来又导致了动模板导向轴承轴线与支撑大杠轴线的不平行，加之原本四个调节齿轮螺母与尾板摩擦面保持平衡调模很顺畅，但支撑大杠不一致的调整又导致调模困难，其结果是各调节螺母受力不平衡、调模不畅出现拉伤支撑大杠螺纹的问题。总而言之，产生上述的缺点是，轴套极易磨损、调模不易、合模精度低、使用周期短、维护成本极高等。
为了解决上述曲肘合模机构所存在的不足问题，申请人先后对现有技术进行了一系列的改进，并先提交了申请号为201521040306.6的用于压铸机或注塑机的万向合模机构，该结构虽然弥补了现行的曲肘式压铸机或注塑机全部的不足，同时又保持了现有流行曲肘机型合模快、合模自锁性好等优点、同时还解决了动模板的两个方向的倾斜难题。但上述申请人提交的用于压铸机或注塑机的万向合模机构，在调整动模板与静模板的平行度时需要在设备工作的间隙时间才能进行，这对运行过程中的设备在出现上述的不平行状况时，不能随时进行调整。

具体实施方式
如图1～图15所示是本发明提供的一种能有效的避免模板在运行过程中，合模后动模板与静模板之间出现不一致间隙的用于压铸机或注塑机的自动万向合模机构。所述的自动万向合模机构包括静模板1、动模板2、尾板3、机铰4和机铰复合连接结构5，所述机铰复合连接结构5的一端通过所述的机铰4与所述的尾板3连接，所述机铰复合连接结构5的另一端与所述的动模板2铰接，在机铰驱动力的作用下，所述动模板2通过所述机铰复合连接结构5与所述机铰4的配合相对于所述的静模板1沿合模方向可往复 移动，在所述机铰复合连接结构5的与所述机铰4连接的一端上设置有动模板平行度自动调节装置51，所述机铰复合连接结构5与所述机铰4连接的一端通过所述的动模板平行度自动调节装置51与所述的机铰4活动连接；运行过程中的所述动模板2相对于所述静模板1的平行度通过所述的动模板平行度自动调节装置51在工作过程中自行调整并保持稳定一致。上述通过在所述机铰复合连接结构5的与所述机铰4连接的一端上设置一套动模板平行度自动调节装置51，并使所述机铰复合连接结构5与所述机铰4连接的一端通过所述的动模板平行度自动调节装置51与所述的机铰4活动连接；然后使运行过程中的所述动模板2相对于所述静模板1的平行度，通过所述的动模板平行度自动调节装置51在工作过程中自行调整并保持稳定。这样，在所述的注塑机或压铸机运行的过程中，由于有所述的动模板平行度自动调节装置51的调整，从而使模具合模后动模板2与静模板1之间不会出现不一致的间隙，进而达到产品不出现飞边毛刺的目的。本申请中所述的动模板平行度自动调节装置实质为一种平面连杆浮动顶紧技术。
上述实施方式中，为了既简化所述动模板平行度自动调节装置51结构，同时又能保证实现其自行调整动模板2与静模板1之间的平行度，从而降低生产成本、方便制造安装和后序的维护维修，将所述的机铰复合连接结构5设置为包括复合铰铰杆52和偏心轴53的结构，这样便可以使所述的机铰复合连接结构5通过所述的复合铰铰杆52和所述的偏心轴53与所述的机铰4活动连接；并将所述的动模板平行度自动调节装置51置成包括自动摆臂511和浮摆齿轮512的结构；同时，在所述自动摆臂511的一端设置浮摆齿5111，在所述自动摆臂511的另一端设置安装孔5112；这样，所述的自动摆臂511便可以通过所述的安装孔5112对称的安装在所述机铰4不同侧的偏心轴上53；同时使位于不同侧偏心轴53上的自动摆臂511通过所述浮摆齿5111与所述浮摆齿轮512的配合，沿相反方向联动的扭转对应位置上的偏心轴53以调整所述动模板2相对于静模板1的平行度。此时，为了方便所述浮摆齿轮512的安装，优选的结构为所述的动模板平行度自动调节装置51还包括安装支撑板513，所述的浮摆齿轮512通过所述的安装支撑板513安装在相互对应的一组所述的自动摆臂511之间；在所述的浮摆齿轮512上设置有安装齿柄5121，在所述的安装齿柄5121上设置有沿周向延伸的锁定凹槽5122，在所述的安装支撑板513上设置有齿柄安装孔5131，在所述的齿柄安装孔5131上设置有沿径向的锁定螺纹孔5132，在所述的锁定凹槽5122中布置有摩擦橡胶圈5123；通过所述的安装齿柄5121和所述的齿柄安装孔5131安装在所述安装支撑板513上的浮摆齿轮512，通过所述摩擦橡胶圈5123和旋接在所述锁定螺纹孔5132中的锁紧螺栓5133 调节。
进一步的，为了实现对所述机铰复合连接结构5的预平行调节，保证在所述动模板平行度自动调节装置51自调节前所述的机铰复合连接结构5相对于所述的动模板2是平行的，本申请对所述的机铰复合连接结构5还增设置了自平衡系统54，所述复合铰铰杆52与所述动模板2的相对位置通过所述自平衡系统调整54。此时所述的自平衡系统54可以为包括自平衡弹簧板541和自平衡调节螺柱542的结构，也可以是包括弹性构件543、平衡力调节组件544和安装腔545。当采用前者时，在所述的复合铰铰杆52上设置有安装槽521，所述自平衡弹簧板541的一端插接在所述的安装槽521内，所述平衡弹簧板541的另一端通过固装动模板2上所述的自平衡调节螺柱542顶紧。当采用后者时，所述的安装腔545设置在所述的动模板2上，所述的弹性构件543布置在所述的安装腔545中，所述平衡力调节组件544的一端顶接在所述的弹性构件543上，所述平衡力调节组件544的另一端旋接在机铰复合连接结构5的两侧；同时，将所述的弹性构件543设置为弹性橡胶，所述的平衡力调节组件544包括相互顶接的调节螺柱5441和压板5442，所述平衡力调节组件544的一端通过所述的压板5442顶接在所述的弹性橡胶上，所述平衡力调节组件544的另一端通过所述的调节螺柱5441旋接在所述机铰复合连接结构5的两侧，以上如附图12。
再结合所述机铰复合连接结构5的两端分别与所述的机铰4和所述的动模板2之间均为活动连接而容易出现失稳或损坏状况现象，本申请所述的机铰复合连接结构5还包括复铰稳定铰框55和偏心轴53，所述的机铰复合连接结构5通过所述的复铰稳定铰框55和所述的偏心轴53与所述的机铰4活动连接；所述的动模板平行度自动调节装置51包括自动摆臂511和浮摆齿轮512，在所述自动摆臂511的一端设置有浮摆齿5111，在所述自动摆臂511的另一端设置有安装孔5112；所述的自动摆臂511通过所述的安装孔5112对称的安装在所述机铰4不同侧的偏心轴上53；位于不同侧偏心轴53上的自动摆臂511通过所述浮摆齿5111与所述浮摆齿轮512的配合，沿相反方向联动的扭转对应位置上的偏心轴53以调整所述动模板2相对于静模板1的平行度。再结合本申请所述的自动万向合模机构还包括支撑大杆6的特点，在所述复铰稳定铰框55的四角处分别设置有与所述支撑大杆6的位置和尺寸相适应的支撑孔551，所述的复铰稳定铰框55沿合模方向可往复移动的支撑在所述的支撑大杆6上本申请采用在所述复铰稳定装置55的四角处分别设置与所述支撑大杆6的位置和尺寸相适应的支撑孔551，使所述的复铰稳定装置55通过所述的支撑孔551沿合模方向可往复移动的支撑在所述的支撑大杆6 上，这样，便可以最大限度的防止大吨位下的压铸机或注塑机在工作时出现失稳或损坏状况现象。
同时，为了避免设备在运行中出现大量的漏油现象，在每一个所述支撑孔551的朝向动模板2的一侧还设置有连接限位导筒552，在所述动模板2的相应位置处设置有与所述连接限位导筒552相应配的限位台阶孔21，在所述连接限位导筒552的内侧壁和外侧壁上分别设置有弹性密封衬环7，所述连接限位导筒552的内侧壁与所述支撑大杆6之间的安装间隙以及所述连接限位导筒552的外侧壁与所述限位台阶孔21之间的安装间隙均通过所述的弹性密封衬环7密封。
当所述的机铰复合连接结构5采用复铰稳定铰框55来连接机铰4和动模板2时，为了方便所述的复铰稳定铰框55与所述的动模板2进行铰接，并传递与之相适应的较大吨位的载荷，所述的机铰复合连接结构5还包括圆弧连接销56和铰接耳板57，在所述的动模板2上设置有连接铰耳22，在所述的铰接耳板57和所述的连接铰耳22上分别设置有与所述圆弧连接销56的横截面相适应的铰接孔8，所述的复铰稳定铰框55通过所述铰接耳板57、圆弧连接销56和所述的连接铰耳22与所述的动模板2铰接。其中，在所述复铰稳定铰框55上与所述铰接耳板57形状和位置相适应处还设置有与复铰稳定铰框55一体成型的铰接限位内耳板58。
同样的，针对现有技术中，所述的复合铰铰杆52与动模板2之间的安装较为复杂，不方便加工的缺点，本申请提供了另一种改进后的结构，即在所述的动模板2上设置有凸弧连接铰耳23，在所述的复合铰铰杆52上设置有与所述凸弧连接铰耳23相适配的凹弧连接铰耳521，所述的动模板2与所述的复合铰铰杆52通过所述的凸弧连接铰耳23和所述的凹弧连接铰耳521铰接；而且将所述的凸弧连接铰耳23与所述的动模板2设置为一体成型结构，将所述的凹弧连接铰耳521与所述的复合铰铰杆52也设置为一体成型结构。需要特别说明的一点是，所述的凸弧连接铰耳23与所述的动模板2也可以分体结构。进一步的，结合一套所述的机铰复合连接结构5包括两组所述的复合铰铰杆52，每一组所述的复合铰铰杆52均包括一个基杆522，所述的凹弧连接铰耳521布置在所述的基杆522上，同一套所述机铰复合连接结构5的两组所述的复合铰铰杆52为以所述的基杆522为基础的一体加工裁取结构，如附图15所示。即将两件所述的复合铰铰杆52以所述的基杆522基础整体造型、加工，然后再沿虚线处切开为两件，最后再进行铰轴孔的加工，以上如图12、图14以及图15。
综上所述，通过设置一套包括偏心轴53、自动摆臂511和浮摆齿轮512构成的平面 连杆机构替代其它复杂的调节机构使动模板2沿曲肘伸缩方向的自动调整变得更加方便、更加直接。通过上述的改进将现有曲肘合模技术中“动模板”不具备万向倾斜功能的技术问题再优化，即将先前申请的万向合模机构中的曲肘方调整用的执行机构再创新优化为本申请的偏心铰轴结构形式的平面连杆自动调节机构，使动模板2两个方向都能自由倾斜，这样一来就解决了模板、模具两个方向的平行度问题。本申请所述偏心轴结构形式的平面连杆自动调节机构的创新技术在于即便模板、模具或者其他不确定因素造成的合模不平行都可以通过本创新优化的自动万向技术随时跟踪修正。所述动模板2与所述支撑大杠6之间导向的所述万向调心组件其创新在于提高了二者之间的导向精度，所述的万向调心组件不因所述动模板的倾斜，所述万向调心组件的轴线与所述大杠轴线平行始终保持一致。为了保证所述动模板运行的平稳还设置了一套包括平衡弹簧钢板和平衡调节螺柱的自平衡系统54，当所述动模板与所述静模板之间的自由平行度可通过所述的平衡弹簧钢板和所述的平衡调节螺柱保证。这样一来，动模板运行更平稳，合模精度也更高，即等同于直压式合模精度，本创新在于模板与模板或模具与模具之间的不接触状态下精度高于现行直压式合模技术，从而实现高端产品的开发应用，填补曲肘机不能生产高端产品的空白。
通过本申请的改进后，再进行模板调整时就不再需要牵拉大杠和其它调节机构了，同时换装模具和调模更畅，动模板运行更稳定，合模精度也更高，即等同于直压式合模精度，本创新在于模板与模板或模具与模具之间的不接触状态下精度高于现行直压式合模技术，从而实现高端产品的开发应用，填补曲肘式合模技术不能生产高端产品的空白。
再者，通过在以上所述的动模板自动万向合模机构中设置一套偏心轴平面连杆机构，实现对现有的技术进行再次优化，从而不仅很好的解决了现有技术中存在的难题，还结省了大量的成本，更方便了制作工艺，更科学化。这样，还可以保证本申请所述的动模板自动万向合模机构在现有曲肘合模技术上解决的技术难题，而且，本创新技术在于投入较小的成本替代其它执行机构，使动模板产生机械自动万向，这在曲肘合模技术上是该领域梦寐以求的一种结果，从而本创新技术有可能在该领域引起对曲肘合模技术与直压式合模技术的重新认可。
