PURPOSE:To avert the generation of strain without the influence of the shrinkage on solidification of a lining material on the shell of a mold by applying a mold release agent on the inside surface of the recess in the shell of the mold prior to injecting the lining material therein. CONSTITUTION:A shell 10 of a mold is produced and thereafter a mold release agent is applied on the inside surface in a recess 20. A lining material 22 is injected into the recess 20. Shrinkage on solidification arises as the solidification of the material 22 progresses, and since the mold release agent is applied in the recess, at least a part of the material 22 parts from the shell 10 thus generating a clearance. The shell 10 is therefore kept free from strain. The solidified material 22 is once separated from the shell 10 and the mold release agent sticking to the inside surface of the recess 20 in the shell 10 and the surface of the material 22 is thoroughly removed. An adhesive 24 is filled in the space between the shell 10 and the material 22 to fit again the shell 10 and the material 22, whereby both are fixed to each other and a mold 26 is obtd. |
