PROBLEM TO BE SOLVED: To provide a self-diagonostic mold apparatus which, provided with a self-diagonostic function, can restrain the breakage of a cavity minimally by limiting to the breakage of an angular pin at the worst. SOLUTION: For the angular pin 13 for opening and closing the slide member 12 equipped in the inside of the mold 11 used for injection molding there are provided the thin holes consisting of the non-penetrating vertical hole 16 extending to the pin axial direction and the horizontal hole 17. To the thin holes are connected the regulator 21 that supplies a compressed air from the outside through the mold and the flow rate sensor or pressure sensor 22 that monitors the pressure of the supplied compressed air.
