The upper end open of described outer die casing and opening part envelope are provided with outer die casing opens the upper end cover being connected, and described plug activity is installed between upper end cover and outer die casing bottom, and described sprue gate is arranged on upper end cover.
On described upper end cover, the removable gate pad that is installed with, offers upper hole on the upper surface of described gate pad, offers the lower plug hole corresponding with upper hole on the upper surface of described upper end cover, and described sprue gate is coordinated and formed by the upper and lower plug hole of correspondence.
The removable increased pressure board that is installed with in upper end of described gate pad, offer the annular gas tank corresponding with upper hole, and increased pressure board has the air inlet being connected with air drain on the lower surface of increased pressure board.
Described gate pad has an airtight cooling chamber, and gate pad is provided with the water inlet being communicated with cooling chamber.
Described sprue gate has two, and two sprue gates are the arcuate socket circumferentially extending along outer die casing.
The upper end of described each plug protrudes upward upper end cover, and extension has thrust step surface, that coordinate with upper end cover block down.
Described outer die casing lower ending opening, and lower ending opening place envelope is provided with and the removable bottom end cover being connected of outer die casing.
Adopt the capacitor tube casting mold of said structure, be flared end owing to pouring into the upper port of die cavity, and sprue gate is arranged on the top of mould, like this by increasing the diameter of gate end, technique feeding when having ensured to be injected into the castable that pours in die cavity and solidifying, can easily the capacitor tube goods after solidifying be extracted out by gate end, be convenient in demoulding, and not be prone to cracking and the phenomenon of colliding with.
Further, by increasing air inlet, after being poured, by air inlet injecting compressed air, further ensure the technique feeding of castable.
Further, increase cooling chamber, inject cooling water by water inlet in cooling chamber, the bubble being beneficial in castable overflows in solidification process, avoids producing defect.
