PROBLEM TO BE SOLVED: To prevent a shape defect of a product tube or the like which is caused by a difference in level between a mold metal and a molding machine base or the like which is generated by a positional adjustment of a mold metal in a tube molding machine.SOLUTION: In a tube molding machine, mold parts 2 and 3 are respectively arranged so as to be opposed to each other up and down as well as right and left and both ends of the tube raw body TR having predetermined length arranged between the mold parts 2 and 3 are positioned and clamped while both end surfaces of the positioned and clamped tube raw body TR are pressed and joined to each other. The mold parts 2 and 3 are equipped with mold metals 15a, molding machine bases 10 for fixing the mold metals 15a in a positionally adjustable manner and arms 20, and the mold metals 15a are fixed to the molding machine bases 10 and the arms 20 in a positionally adjustable manner for the purpose of the positional alignment of both ends of the tube raw body TR and extended in the extending direction of the tube raw body TR and equipped with the mold metal cover pieces 15b for covering the tube raw body opposed surfaces of the molding machine bases 10 and the arms 20. The clamping of the tube raw body TR is performed through the mold metals 15a. |
