PROBLEM TO BE SOLVED: To provide a method for changing cartridge system heating barrel, regarding a screw and a heating barrel as one set, in which a heating barrel with an inserted screw is dismounted from an injection unit to be replaced with another heating barrel with an inserted screw. SOLUTION: In the method of changing the heating barrel with the inserted screw of an electric injection molding machine which executes advancement of the screw at injection by the rotation of a ball screw provided behind the screw, a U-groove, which the heating barrel can pass through from the surface of a fixing plate in the axis direction of the barrel, is provided on the fixing plate which is cantilevered with the heating barrel, and a block is provided which fits to the U-groove and presses the heating barrel against the bottom surface of the U-groove. In order to change the heating barrel with the inserted screw, the block fitted to the U-groove is dismounted and then the heating barrel is taken out along the U-groove. COPYRIGHT: (C)2010,JPO&INPIT
