PURPOSE: To prevent an engagement part for a projecting part and a recessed part facing a cavity from being damaged, in a die device which molds the case half of MFD. CONSTITUTION: Each cavity core 28 of the fixed half 21 of a die and each core 33 of the movable half 22 have an engagement part for a projecting part and a recessed part facing a cavity 23 on account of the shape of a finished product. Each core 33 which forms each cavity 23 is movable independently of the other core in an orthogonal direction to a die opening direction. A positioning projecting part 42 is provided outside the cavity 23 by each core 33. Each core 33 has a corresponding positioning recessed part 44. If the die is closed, the positioning projecting part 42 becomes engaged with the positioning recessed part 44, so that the corresponding cores 33 can be aligned using each cavity core 28 as a reference. Thus the damage by the interference of the engagement part can be prevented from occurring. |
