It pours the system to use the side runner, the trapezoidal minute flowchannel, the sufficient mold speed quick, safe is reliable. The mold used the slantingguide pillar in the structure to pull out the core organization, reduced the workergreatly the labor intensity, caused the mold to hold in the production process doesconveniently.Key words: Casts the mold Minute profile Pours the system The slanting guidepillar pulls out the core organization Side runner
