PROBLEM TO BE SOLVED: To provide a die for producing a resin molding having a good appearance without generation of burr, etc. on outer spherical line parts of a plane projecting drawing in a clamping direction of the synthetic resin molding.;SOLUTION: In a die for producing a synthetic resin molding, one die and a part of or a whole of the outer spherical surface are provided with a movable moving die, another die capable of bringing its parting surface in contact with an upper part of the outer spherical surface and a mechanical clamping mechanism jointing mechanically the outer spherical part of the moving die to the other die, and the mechanical clamp comprises a clamp having a U shape, wherein a ditch or inserting hole is provided at predetermined positions of the other die and the moving die in such a way as to be capable of inserting the both ends of the clamp into the ditch or the inserting hole, the moving direction of the moving die 2 is the same with the opening/closing direction of both of one die and the other die, and the one die and the other die are disposed in such a way that the moving surfaces of the one die and the other die are positioned inside of the outer spherical lines of the plane projecting drawing in opening/closing direction of the die for producing the synthetic resin molding.;COPYRIGHT: (C)2007,JPO&INPIT
