CONSTITUTION: In a fixed mold 32 and a movable mold 33 which form a cavity 31 between them and a fitting hole 50 provided on the wall face of one of the molds forming the cavity 31, a sleeve 49 to be fitted from the cavity 31, a stamper 39 whose inner periphery is to be engaged with an engaging flange 51 to be formed at the end of the cavity 31, and a closely connecting means for attaching the stamper 39 along the wall face of the cavity 31 are provided. The closely connecting means has a peripheral groove 52 provided on the side face of the sleeve 49 and an engaging pin 56 to be inserted from a direction to cross the axial line of the sleeve 49. The engaging pin 56 is inserted into the peripheral groove 52 of the sleeve 49 to be arranged in the fitting hole 50 so as to stop the movement of the sleeve 49 in the axial direction and closely connect the stamper 39 to the wall face of the cavity 31 assuredly. |
