Abstract
PURPOSE: To manufacture simply and inexpensively a curved pipe of complicated shape made of thermosetting rubber or the like by a method wherein a straight pipe of unvulcanized material is inserted into the cavity of a shape equivalent to the outer shape of a required curved pipe and compressed air is supplied to vulcanize the pipe.
CONSTITUTION: A split mold consists of a lower mold 1a and an upper mold 1b, and a cavity 2 of a shape equivalent to the outer shape of the curved pipe is carved on the their mating surface. On both ends of the cavity are provided opening 21, 22 in the form of a straight pipe necessary to connect the curved pipes after molded to other pipes. The lower mold 1a and the upper mold 1b are clamped with clamps 3a, 3b. The upper mold 1b is separated from the above-said lower mold 1a and the original pipe P is fitted for the curve of the cavity 2 and inserted into the cavity 2. Then, internal pressure is given by supplying compressed air through a pressure plug 4, and the original pipe P is formed after the cavity 2, attached tightly to the inside of the cavity, prevulcanized in an air over for a short time and formed. Then, the prevulcanized curved pipe is taken out and vulcanized finally.
