Abstract:
The present invention addresses the problem of providing a casting device with which it is possible for the inside of a cavity to be maintained in a reduced-pressure condition. A casting device (1) is configured such that a cast product is released by causing a pushing-out pin (3) inserted slidably into an insertion hole (29) formed in a die (2) to project into a cavity (20). The die (2) includes cavity surface (2a), and a reduced-pressure space forming body (4) for forming a reduced-pressure space (40) on the reverse side thereof. The reduced-pressure space forming body (4) is capable of maintaining the inside of the cavity (20) in a reduced-pressure condition by covering an opening portion of the insertion hole (29).
