本发明的工作原理为：
如图1和图2所示，
1、两个夹持机构在对应砂型输送线上面。一个夹持机构夹持套箱或(和)压铁位于第一列砂型输送线71上方时，砂型移动车在轨道73上，夹持机构2下降卸下套箱或(和)压铁，夹持机构空载上升复位，完成对砂型压实；同时另一个夹持机构夹持套箱或(和)压铁位于清砂机构上方，夹持机构下降卸下套箱或(和)压铁，卸下套箱或(和)压铁的过程完成套箱清砂，压铁安放平稳后， 移动刷42往复清扫压铁61工作面上的残砂，夹持机构2空载上升复位，整个过程完成套箱62或(和)压铁的清理。
2、两个夹持机构2在对应砂型输送线7上面。一个夹持机构2空载位于第二列砂型输送线72上方时，夹持机构下降，抓取第二列砂型输送线上的套箱62或(和)压铁，夹持机构上升，完成第二列砂型输送线72上的套箱或(和)压铁的拆卸；同时另一个夹持机构2空载状态下位于清砂座41上方，夹持机构下降，夹持承托清砂座41上已分别完成残砂清理的套箱或(和)压铁，夹持机构上升，预备下一步套箱或(和)压铁的安装。
3、夹持机构执行上述第2项工作后，接着执行第1项工作。
4、又如图1、图3所示，夹持机构为两组两个在对应砂型输送线7上面工作，仍然按照上述第1)、2)、3)项执行工作，连续循环完成套箱62或(和)压铁61的安装、残砂清理和拆除工作。
或者，夹持机构为两组两个在对应砂型输送线7上，一组两个夹持机构2夹持承载套箱62依次完成套箱62的安装、残砂清理和拆除工作；另一组两个夹持机构2夹持承载压铁依次完成压铁61的安装、残砂清理和拆除。
5、显而易见，夹持机构可以为1组2个或多组2个在对应的砂型输送线7上，夹持机构的组数不受具体限制；1组2个或多组2个夹持机构完成套箱62或(和)压铁61的安装、残砂清理和拆除工作。
另外，夹持机构2可以为仅夹持承载套箱62工作；或者夹持机构2可以为仅夹持承载压铁61工作；或者夹持机构2可以为同时夹持承载套箱62、压铁(61)工作。
本发明中如图3及上述所述，生产线中可设有多组2个夹持机构2。如上述，其可实现1个夹持机构同时夹持承托套箱62和压铁61工作。而设有多组夹持机构可实现分别对应夹持承托多组套箱62或(和)压铁61工作。或者多组夹持机构2分别夹持压铁工作；或者多组夹持机构2分别夹持套箱62工作。
如图3，设有2组夹持机构2，一组夹持机构用以夹持承托压铁62工作，另一组夹持机构用以夹持承托套箱61工作。多组夹持机构2的具体工作方法可根据实际选定，不受严格限制。
如图7为一种套箱62压紧无箱铸造砂型63的示意简图，无箱铸造砂型63被仿形的套箱62圈套压紧，套箱对应上砂型631和下砂型632结合处，浇注时可防止出现抬箱或错箱，保障安全生产并提高铸件产品合格率。又如图8所示，为进一步避免浇注出现抬箱现象，可在无箱铸造砂型63上面加压压铁61，压铁对应砂型设置有浇注口614。
再结合图9、图10，可看出，安装了套箱62和压铁61的无箱铸造砂型通过砂型移动车74承载在砂型输送线7上运行；套箱62和压铁61可通过定位销611和定位槽625配合，以防止套箱62、压铁61的安装、拆除过程出现跑偏等意外情况的发生，而且夹持机构只需夹持承托套箱62的套箱托板Ⅰ621、套箱托板Ⅱ622、套箱托板Ⅲ623以及套箱托板Ⅳ624便可同时完成套箱62、压铁61的安装、拆除等；套箱62的套箱托板使得夹持机构2夹持承托套箱6过程方便、快捷。
结合图1、图2所示，夹持机构为2个并列设置，夹持机构2位移的起点或终点分别与砂型输送线7对应。
再结合图1、图3所示，夹持机构2为2个或多个并列设置，夹持机构2位移的起点或终点分别与砂型输送线7对应。
夹持机构2可以共用一个夹持机构移动车3工作；或者夹持机构2分组对应 与1个夹持机构移动车连接工作；或者1个夹持机构2对应连接1个夹持机构移动车工作。
如图2、图3、图12、图13所示，支座Ⅰ15用以放置压铁61，以便清理压铁61表面附着的残砂。压铁61可安放在支座Ⅰ上，支座Ⅰ15设在机架1上；支座Ⅰ15数量可以为2个或4个等设为一组；支座Ⅰ上可设有导板Ⅰ151和导板Ⅱ152。安放压铁时可避免压铁61跑偏而影响工作；支座设有调节螺栓154，以便适当调整支座的高度或支座15组的高度一致性。
如图1、图2、图3、图11所示，清砂机构4主要包括清砂座41和移动刷42。清砂座41清除套箱62内壁附着的残砂；移动刷42清除压铁61表面附着的残砂。
如图11，清砂座41的形体为套箱内腔的仿形结构形式；清砂座41主要包括座体411、固定座412、刷板座413以及板刷414；清砂座41通过刷板座413固定在清砂座基座11上；清砂座基座11设在机架1上处于支座Ⅰ15的下方，固定座通过螺栓Ⅲ416固定。
清砂座41上部的四周通过板刷座413固定有板刷414，用以清扫套箱62内壁附着的残砂。板刷414可通过螺栓Ⅱ415调节与套箱内壁的距离；板刷414也可通过固定螺栓153实现快速更换。
如图2和图3，移动刷42设置在支座Ⅰ15下方合理高度位置；移动刷42固定在移动刷往复驱动结构56的端部，移动刷往复驱动结构为往复缸；往复缸可通过缸座14固定在机架1上；往复缸56通过导杆55平稳工作。移动刷42可调节与压铁61下表面的距离；移动刷42可实现快速更换。
上述仅为对本发明较佳的实施例说明，上述技术特征可以任意组合形成多个本发明的实施例方案。
上面结合附图对本实用新型进行了示例性描述，显然本实用新型具体实现并不受上述方式的限制，只要采用了本实用新型的构思和技术方案进行的各种非实质性的改进，或未经改进将本实用新型的构思和技术方案直接应用于其它场合的，均在本实用新型的保护范围之内。
