Abstract
PURPOSE:To make repairs in a small number of processes and also to make a part in repair hard to damage by cutting off cracking and fusion-defective parts on lower and upper injection surface plates and by inserting and fixing an extra inserter of the same material as the cut parts to the cut part. CONSTITUTION:To reduce cracking 2 of lower injection surface plate 1 the part is cut off to form concave part 10. Next, inserter 11 for the stopgap of the shape of original surface plate 1 matching with concave part 10 is made of an ingot of the same material as surface plate 1 and several bolt holes 12 are made to an adequate number. Next, screw holes are made in the concave part of surface plate 1 corresponding to bolt holes 12 and inseter 11 is inserted into concave part 10 and then fixed by tightening up bolts. In this method, surface plate 1 has no cracking 2 left and, inconsequence, the advance of cracking is cmpletely prevented, so that inserter 11 will be hard to damage because of expansion as much as surface plate 1.
