PURPOSE:To improve the general-purpose property of the same mold device by removing the inter-mediate cavity member constituting the part in depth direction and replacing it by the cavity member having different width in depth direction in the flow molding of the hollow body such as the cell tank of a tetragonal shape having the size different in clamping direction. CONSTITUTION:In the right side-mold device 2 of left and right symmetrical mold device, an inner side wall member 7 is movable in clamping direction. In the auxiliary member 12, a plurality of auxiliary wall surface 13 with different width (d) are provided, and the cavity of a prescribed depth D is obtained by replacing the auxiliary member 12 or removing said member. The left and right mold devices are closed in the state where the front end of a parison hangs down, and the step part 27 of the inner side wall member 7 is engaged with the end surface of the inner side-lower frames 24, 24 of left and right lower side wall surfaces 4d, 4d, and then left and right base holders 22 are elevated. The auxiliary member 12 and an auxiliary frame 25 are replaced or removed, whereby the width in clamping direction of front and rear side wall surfaces 4a, 4b and the lower side wall surface 4d may be changed. |
