The second sealing ring being adjacent to the bottom wall of lower opening is provided with second annular groove.
By using above-mentioned technical proposal, due to capillary phenomenon, flow downwardly in relief hole, in some instances it may even be possible to flow into cast gate
Place, causes damage of product；By setting the second sealing ring, current can be obstructed in fortune water jacket bottom wall, prevent current flow into from allowing
In the hole of position, yield rate is improved.
Further, the hot nozzle includes nozzle core, and the outer coaxial sleeve of the nozzle core, which is equipped with, to be extended downward into outside hot nozzle
Pressing sleeve, the outer circle wall that the pressing sleeve is located at outside hot nozzle is coaxially arranged with to offset with fortune water jacket inner wall, and will transport water jacket stretching
Pushing out ring on lower opening inner wall.
By using above-mentioned technical proposal, during installation, first fortune water jacket is installed in stepped hole, then loads pressing sleeve,
By interference fit, make pushing out ring be caught in fortune water jacket you, and support greatly, make fortune water jacket and the connection of lower opening inner wall closer, into
And the first sealing ring is further compressed, increase sealing effect；Pressing sleeve can also carry out location and installation to nozzle core.
Further, the locating piece is connected by bolt with solid plate, and fortune water jacket is pushed against downwards to the bottom of lower opening
Wall.
By using above-mentioned technical proposal, locating piece is connected with solid plate by bolt, it is downward for water jacket will be transported
Push against, and the second sealing ring of fortune water jacket bottom is further compressed, so as to increase sealing effect.
Further, the locating piece side is provided with positioning plane, and the upper hole profile is consistent with locating piece profile.
By using above-mentioned technical proposal, plane is positioned by setting, will fortune water jacket load in stepped hole when, for pair
Locating piece is positioned, and is aligned easy to screw hole, positions plane in addition and also has rotation stop effect.
In conclusion the utility model has the advantages that：
1st, by setting spiral helicine sink on fortune water jacket, there is good cooling effect, fortune water jacket processing is simple, adds
Work cost is low；
2nd, by setting the first sealing ring and the second sealing ring, it can keep good sealing effectiveness, avoid leak；
3rd, by setting pressing sleeve further to increase leakproofness.
