Abstract
PURPOSE:To cause cracks not to be generated in the process in which a molded object is taken out from a mold after molding by a method in which a ridge is formed on the position corresponding to the mating part of the mutual mold pieces of a split mond on the surface of a molded object, and a recessed groove is formed in the mating part of each mold piece of the split mold. CONSTITUTION:A molded object 5 has a cylindrical shape as a whole, and has ridges 6 integrally formed respectively along the axial split lines of this cylindrical body on its peripheral surface. The ridge 6 is provided with the angle-shape in cross-section with the vertical angle of about 90 deg.. The vertical angle of the ridge 6 is preferably 90-150 deg., and its height is preferably about 1-5mm. A split mold 7 is composed of the outer mold made of the combination of two arcuate mold pieces 8, an almost columnar inner mold 9 and the bottom mold 11 closing the bottom end of a vertical and cylindrical molding cavity 10. When two mold pieces 8 are assembled into a cylindrical body by using a tightening band 13, on the molding surface 8b of the outer periphery of the molding cavity the recessed groove 14 of V-shape extending to the side of the molding cavity along the mating part 8a of the adjacent mold pieces, is formed.
