PURPOSE:To replace a stamper by removing a mirror board by using an inner peripheral ring with a stamper fitting into its center and an outer ring fitting on the outer periphery and fitting the inner peripheral ring in a guide component to accommodate the mirror board in a recessed section and fitting said unit in an insert die integrally. CONSTITUTION:The mold surface side of an insert die 5 to be accommodated in the center of a base mold 3 is formed on a round recessed section 7 and a guide component 11 of short cylindrical shape is provided projectingly on the center of the recessed section, and a mirror board 16 which is mounted on the mold surface by means of an inner peripheral ring 18 fitted with a stamper 21 fitted in its center and an outer peripheral ring 20 fitted on the periphery, is fitted in the recessed section 7 by fitting the inner peripheral ring 18 in the guide component 11 and fixed in the insert die 5 integrally. Thus, the stamper 21 can be replaced by using the insert die 5 removed from a base mold 3 as a supporting bed, and if necessary, the mirror bed 16 is released from the insert die 5 together with the stamper 21 for the replacement of the stamper. The replacement of the stamper 21 can be carried out easily simply by removing the mirror board 16 in said arrangement. |
