The utility model relates to an improved runner system used for an automobile timing sprocket shell die casting die. Its characteristic is that the runner system is arranged in a mold cavity on one side of the sprocket suspension position, including a straight runner, two groups of cross cast-in-place channels formed at the end of the straight runner, and three transverse sections on a set of cast-in-place channels. Four cast-in-place branches are drawn out on the other set of cast-in-place channels. The two cast-in-place branches near the inside of the four cast-in-place branches are connected by a gate to the corresponding cavities of the sprocket suspension. The branch of the four cast-in-place branch near the outside is connected by the gate to the corresponding end of the mold cavity. . The improved runner system solves the problem of air holes on the mounting part of the timing chain wheel housing.

用于汽车正时链轮壳压铸模具上的改进型浇道系统
本技术属于汽车正时链轮壳浇铸
,特别涉及一种用于汽车正时链轮壳压铸模具上的改进型浇道系统。
技术介绍
现有用于汽车正时链轮壳压铸模具上的浇道系统整体设置于正时链轮壳上悬置部位的相对侧,参见图2,浇道系统具体由直浇道和与直浇道连接的两组横浇道构成,一组横浇道上引出两个横浇道分支,另一组横浇道上引出三个横浇道分支,五个横浇道分支各通过一浇口与模具型腔的对应侧不同部位连通。使用上述浇道系统浇铸生产的正时链轮壳在悬置部位气孔现象较严重,从而很难保证铸件的品质。
