发明名称 MOLD AND MOLDING METHOD FOR PLASTIC SUBSTANCES MOLDING TO ELBOW
摘要 A tune tolerance synthetic resin forming metal mold and a molding method using the same for removing the mold element of the curved pipe are provided to facilitate the separation of the walls from the curved pipe and rotate the walls by a hydraulic cylinder. A tune tolerance synthetic resin forming metal mold includes two flange press units and bending pipe units. The flange press assembly comprises the straight pipe unit, a flange unit, an inner circumference connecting unit, resin gates, air exhaust holes of cylindrical. The inner circumference connecting unit is extended from the straight segment. The inner circumference connecting unit is formed in both ends of each wall. The first wall gathers together with the hydraulic cylinder connected to the inner side of the first wall. A hydraulic cylinder(28) is connected to the inner side and the second wall gathers together with the fluid pressure. The bond and separation are possible with the inner circumference connecting part of the flange press assembly.
