PURPOSE:To surely and easily load/unload an inner diameter stamper presser. CONSTITUTION:A stationary mold 41 consists of a first mold member 46 and a second mold member 47 which can be opened/closed. An inner diameter stamper presser 73 and a rotating fixture 87 for fixing it are embedded in the first mold member 46. When a stamper 71 is to be replaced, firstly both the mold members 46, 47 are opened, and the rotating fixture 87 is rotated by a rotating jig 132 while an inner diameter stamper presser 73 is pressed by an extraction jig 131. In this manner, an engaging projection 90 of the rotating fixture 87 is disengaged from a receiving projection 84 of the inner diameter stamper presser 73, and in this state the inner diameter stamper presser 73 is extracted. An inner diameter stamper presser 73 is again mounted by conducting the procedure in a reverse order. The inner diameter stamper presser 13 is fixed by hooking the engaging projection 90 on the receiving projection 84 from a cavity side. |
