Abstract
The invention discloses a step type gating system for pipeline castings without branch pipes. The step type gating system for the pipeline castings without the branch pipes overcomes the shortcomings that because the pipeline castings are long and the design of existing gating systems is unreasonable, temperature distribution in cavities is not uniform and shrinkage cavities, shrinkage porosities, cold shut or incomplete gating exists because gas is not discharged completely. The step type gating system for the pipeline castings without the branch pipes comprises a sprue, a pipeline casting cavity and at least two inner gates, wherein the center axis of the sprue and the center axis of the pipeline casting cavity are vertical, the inner gates are sequentially arranged between the pipeline casting cavity and the sprue from top to bottom, and the two ends of each inner gate communicate with the sprue and the pipeline casting cavity respectively. The step type gating system for the pipeline castings without the branch pipes has the beneficial effects that the shortcomings such as shrinkage cavities, shrinkage porosities, cold shut and incomplete gating of the pipeline castings can be reduced.
