The working principle is as follows: during working, a worker places a mold to be repaired on the top of the placing plate 2017, and then rotates the two groups of screws 2018 respectively to drive the two clamping plates 2019 to move towards the approaching direction until the mold is clamped.

Then, according to the damaged position of the mold, the first hydraulic cylinder 2006 is started to drive the two hinge rods 2007 to rotate, the hinge rods 2007 drive the two bottom rods 2005 to rotate, the connecting block 2003, the second spring 2004, the supporting plate 2008, the second hydraulic cylinder 2009 and the third spring 2011 are matched to drive the T-shaped slider 2010 to move, so that the rotating plate 2013 and the clamping plate 2019 are driven by the fixing frame 2002 to move up and down, the two sets of second hydraulic cylinders 2009 are matched to extend or shorten simultaneously to change the up and down position of the mold accurately, then the two electric telescopic rods 22 are started to push the positioning mechanism 2 to slide back and forth by matching with the slider and the sliding groove on the top of the base 1, so as to change the front and back position of the mold, then the two second hydraulic cylinders 2009 in the same starting direction are extended or shortened simultaneously, and by matching with the T-shaped sliding groove, the third spring 2011 and the T-shaped slider 2010, the rotating plate, the second motor 2015 is started to drive the big gear 2014 to rotate through the small gear 2016, the big gear 2014 drives the rotating plate 2013 and the clamping plate 2019 to rotate left and right through the rotating shaft 2012, so that the mold rotates left and right, the first motor 6 is matched to drive the lead screw 7 to rotate, the lead screw 7 drives the welding wire 18 to move left and right through the sliding sleeve 8 and the fixing plate 9, and the welding wire 18 is aligned to the damaged part of the mold.

Start aspirator pump 21 and send into nozzle 15 through the carbon dioxide gas in trachea 20 with carbon dioxide gas pitcher 3, and through the fumarole blowout of air cock 15 bottom, start welding power 10 after that, thereby make between welding wire 18 and the mould form electric arc in carbon dioxide protective gas, carry out the build-up welding to the mould and restore, start wire feeding motor 19 simultaneously, cooperation tensioning roller 13 and wire feeding wheel 17 with the stable follow unwrapping wire roller 11 above-mentioned transport to restoration department of welding wire 18, and first motor 6 drives the left-right removal of welding wire 18, the mould position is adjusted to cooperation positioning mechanism 2, thereby accomplish the repair work of mould damaged department.

The electrical components presented in the document are all electrically connected with an external master controller and 220V mains, and the master controller can be a conventional known device controlled by a computer or the like.
