The utility model content
Technical problem to be solved in the utility model is, provides a kind of and can bring into play pushing off the slag, scavenging action, and can reduce the apparatus for pouring of casting main shaft casts of stators in the wind-driven generator that shrinkage cavity, shrinkage porosite form probability.
For solving the problems of the technologies described above, the apparatus for pouring of casting main shaft casts of stators in the wind-driven generator that the utility model provides, comprise and be provided with the into sprue of iron liquid end, cross gate and ingate, described sprue communicates with cross gate, described cross gate communicates with ingate, described ingate comprises a circular cross-runner and a plurality of vertical transition running channel, described circular cross-runner is positioned at the periphery at maximum gauge place, casting main shaft casts of stators die cavity lower end, and communicate with die cavity by a plurality of radially running channels identical with vertical transition running channel quantity, described circular cross-runner communicates with sprue; Described vertical transition running channel one end communicates with running channel radially, and the other end communicates with the die cavity at major diameter place, casting main shaft casts of stators middle part.
After adopting this structure, compared with prior art, it has following advantage: because this apparatus for pouring is to have adopted bottom gating, structure by circular cross-runner and a plurality of vertical transition running channels, make balanced each place that arrives die cavity of molten iron energy, can prevent the sand washing defective, and help the come-up of slag class impurity and bubble in the molten iron.
The cross section of described circular cross-runner is trapezoidal.In other words, this ring runner is tubaeform, and is thin and wide, helps weakening high temperature liquid iron to the washing away of casting mold, and can prevent the sand washing defective, also is beneficial to pushing off the slag.
Described sprue comprises first sprue and second sprue, and described cross gate communicates between first sprue and second sprue and with both; Described circular cross-runner communicates with second sprue.After adopting this structure, can change the position of sprue, make the design of running channel more reasonable according to the needs of actual conditions.
Described cross gate comprises cross gate and following cross gate, and described going up between cross gate and the following cross gate is provided with filter.
The junction of described second sprue and circular cross-runner is provided with filter.
Described each radially be equipped with filter block in the running channel.
Adopt the above this structure that increased filter block or filter, help stopping slag class impurity.
