Abstract
The utility model discloses a gating system for a full slice joint flash ingate, which belongs to the field of casting technology, and solves the problems that the conventional gating system is not suitable for casting large-scale casts and has high rejection rate. The gating system comprises a main downsprue, a cross gate, a branch downsprue and a cavity, and is characterized in that the branch downsprue is communicated with the cavity through the full slice joint flash ingate. In the gating system, molten metal is led into the cavity through the full slice joint flash ingate, and the total sectional area of the full slice joint flash ingate is large enough to be 2 to 4 times of that of the downsprues, so that speed of the molten metal passing through the full slice joint flash ingate is greatly reduced, the flow rate of the molten metal entering the cavity is greatly increased, and the molten metal can achieve steady and fast mold filling, so as to achieve the purpose of large-flow low-speed mold filling, accordingly, the quality of casts is guaranteed. The gating system is suitable for casting various large-scale casts.
