横浇道

该系统包括压铸模浇注系统的直浇道、横浇道、内浇口、溢流槽和排气槽。

The system includes sprue , runner , gate , overflow launder , venting launder .

直浇道、横浇道和内浇道截面比为1∶3∶5，并配合带缓冲结构的合理缝隙，可保证型腔内液面上升平稳，减少铸件内部二次氧化夹杂和混入性气体；

The 1 ∶ 3 ∶ 5 cross sectional area ratio of the sprue , runner and gate and the rational fissure with cushion structure make the molten metal fill stably in the mould cavity , that reduce the secondary oxide inclusion and the invading gas ;
