Abstract
PURPOSE: To easily reproduce a wood pattern having reached its service limit and save the cost of manufacturing patterns by making a mold with said pattern, removing the inner side surface of the pattern and injecting a reinforcing coating agent in the clearance of the mold thereby repairing the same.
CONSTITUTION: Molding sand is packed in a pattern 1 made of wood which has worn and become dimensionally inaccurate upon longterm use, whereby a mold 2 is made. Thence, this mold 2 is taken out from the wood pattern 2, and the thickness 4 nearly constant over the entire surface of the inside surface 3 is removed by using woodworking tools or the like, whereby a corrected pattern 1' is made. On the other hand, a release agent is coated on the entire outside surface 5 of the mold 2 and the pattern is again fitted into the cavity in the corrected pattern 1', then the space 4' of nearly uniform thickness is formed between the removed inside surface 3' of the corrected pattern 1' and the outside surface 5 of the mold 2. Next, a reinforcing coating agent 6 prepared by adding a hardener to a molten synthetic resin is injected into the space 4' and the pattern 2 is taken out after it has solidified. Hence, the corrected pattern 1' assumes the state that the reinforcing coating film has stuck over the entire surface of its inside surface, thus the repaired pattern of an accurate size is obtained.
