摘要

PROBLEM TO BE SOLVED: To improve a shell mold joining device which can prevent waving and distortion of a flange parts in the upper and the lower shell molds by supporting the upper and the lower shell molds with sufficient force without accompanied with a complicated constitution and also, affecting the unevenness of thickness in the mold. ;SOLUTION: In either one of mold 13 in the upper and the lower molds 36, 13, a through-hole 16 penetrated from the back surface side thereof to the mating surface 37, with the other side of mold 36, is arranged. A supporting means 47 inserted in the throughhole 16 from the back surface side of the one side of mold 13 and abutting on the mating surface 37 of the other side of mold 36, first pressing means 68, 69 for abutting on the back surface side of the other side of mold 36 and pressing the other side of mold 36 and interposing the other side of mold 36 together with the supporting means 47 and a second pressing means 56 for supporting the back surface of the one side of mold 13, are provided. Then, the pressing timing of the first pressing means 68 corresponding to the supporting means 47 is set at earlier than that of the first pressing means 69 corresponding to the second pressing means 56.;COPYRIGHT: (C)1998,JPO
