Coaxial fluorescent lamp core structure precision forming die

The utility model relates to a structure precision forming die, the more specifically coaxial fluorescent lamp core structure precision forming die that says so, the location is protruding to make down between die body and the last die body cooperation closely good, and the connecting pin further makes down between die body and the last die body cooperation closely not well, makes fashioned coaxial fluorescent lamp core structure well -formed in the time of plug hole I and plug hole II, the high quality. The die body is passed in the up end of die body and the lower extreme facial features contact of last die body down, connecting pin and the lower extreme and lower die body fixed connection of connecting pin. Two protruding settings respectively in the left and right sides of last die body in location, location arch and the upper end cooperation of die body down. It is connected chamber, tube core structure arch chamber, tube core and ties components are installed chamber and optical device core lumen down to form the tube core structure in proper order from the left hand right side between die body and the last die body. Optical device core pipe die sets up in the inside of optical device core lumen, and components are installed chamber intercommunication, plug hole II and optical device core lumen intercommunication are tied with the tube core to plug hole I.
