Abstract
A conduction member having conduction path for injecting molten molding material within a mold space is fitted to one of a pair of mold bodies which form the disc-shaped mold space. A first heat suppressing member for suppressing heat within the conduction path from being transmitted to the one of the mold bodies is disposed between the conduction member and the one of the mold bodies. Further, a second heat suppressing member is disposed at a position opposite to the first heat suppressing member at the time of mold-clamping the pair of the mold bodies.
