METAL BELLOWS MOLDING METHOD FOR BULGE PROCESSING, AND METAL BELLOWS MOLDING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a clamp method which is intended for a mechanism configured to open and close a pair of split molds in a lateral direction and to be combined by the clamp method, and which makes it easier to perform fixing to an apparatus body and sure and firm attachment of the split molds.SOLUTION: A mold body is made up of a pair of split molds 25 and 26 that are free to open and close leftward and rightward. A pivot part is disposed at a lower end portion of each of the split molds. The split molds are clamped by a clamp plate at an upper end portion of each of the split molds, and are free to open and close and move forward and backward by being guided leftward and rightward. The split molds are also fixedly connected to the apparatus body.SELECTED DRAWING: Figure 3
