HIGH-VACUUM DIE-CASTING DIE DEVICE DISCHARGABLE LIQUID BY VACUUM PRESSURE

摘要

The present invention relates to a high-vacuum die-casting die device having a sealing body which surrounds and seals a space in which an eject plate is arranged. According to the present invention, the high-vacuum die-casting die device has a sealing body coupled to a rear surface side of an operation die to surround the eject plate and one end portion of the eject pin, comprising: a discharge port to discharge a liquid such as a release agent, moisture, or the like which flows into a sealed space in the sealing body to stagnate from a cavity side to the outside of the sealed space; and a valve to open and close the discharge port. As such, a liquid stagnating within the sealed space is able to easily be discharged to the outside.
