Camshaft pouring system

The invention provides a camshaft pouring system which comprises a pouring cup, flow gates and camshaft cavities. The pouring cup is directly connected with the flow gates, and fiber filter screens are arranged at connectors between the flow gates and the camshaft cavities. According for further improvement, a foam ceramic filter screen is arranged at the pouring cup. The fiber filter screens are arranged at the combination positions of the flow gates and the camshaft cavities, after pouring is completed, inclusions are formed between the flow gates and castings after molten iron is solidified, then the castings are broken at the positions of the inclusions, sprues can be peeled off with small force, and therefore camshafts are effectively prevented from being damaged when a pouring system is removed and are completely prevented from being broken. Two-stage filtering is achieved through foam ceramic and the fiber filter screens, so that the purity of molten iron is guaranteed. 本发明提出了凸轮轴浇注系统，包括浇口杯、内浇口、凸轮轴型腔，浇口
