Abstract
A cavity die ( ) has a flange part ( ), a body ( ), and a cavity surface ( ). An annular groove ( ) is formed on a periphery of the body ( ). A region surrounded with the annular groove ( ) and a retaining plate forms a boundary flow path. An inner flow path ( ) is formed inside the body ( ). The inner flow path ( ) is linear. Both ends of the inner flow path ( ) are open on a peripheral surface of the body ( ) to form openings ( ) thereon. A heating medium flows into the boundary flow path and the inner flow path ( ) through a flow path formed on the retaining plate. Thereby, the temperature of the cavity die ( ) is adjusted.
