Diffuser type gate structure of the hot water cover in the casting die of the battery pole pillar for industry

摘要

(57) Abstract Topic With casting die of battery pole pillar for common industryThe hole for the said gate at the most in regard to the gate structure of the hot water cover, 3At the same time it becomes excessive because, when casting, the casting hot water gate percolationOccasion, to cause overflow phenomenon, for the sake of, the metal texture of the pseudo shift rear grain conversionWith growth occurring frequently of the blow hole, to cause mechanical strength insufficiency, enduranceQuality performance problem such that it is lacking in Characteristic existing, it stayed. Solutions Casting the battery pole pillar (B.P) for industryIn the die (C.V), the hot water cover (M: C) it Perforating facilities it does, multi-Several gates (G))To in regard, the battery for the said, industryEach cavity center of pole pillar (B.P) (C)To make standard, at the same time consecutively, concentric circular suitable number (n), suitablenessGate (G) of ru size (d)Multiple borehole forma facilities seAs though it depends on closing and the , it waters with the sprinkler,Diffuser type ge of the hot water cover where the casting can accomplishIt makes to structure (D.G.S).
