水平造型线给定直浇道的浇注系统设计

多数水平造型线有着固定尺寸的直浇道、浇口杯、砂型高度,需要在这些参数固定的情况下设计适用于不同浇注重量的浇注系统。基于大孔出流理论,对其中的公式进行了推导。提出了一种浇注系统设计方法,并对该方法的适用范围进行了探讨。结果表明,该方法在一定范围内可以满足设计要求,内浇道出流速度合理,浇注过程中浇道呈充满状态。

Design of Gating System for the Given Sprue of the Horizontal Molding Line

In most horizontal molding lines,each of sprue,pouring cup and sand mold height has its own fixed size.In actual production.Often it is needed to design pouring system for different pouring weights under these fixed parameters.Based on the large orifice discharge theory,a new method was proposed and discussed.Results show that the method can meet design requirement within certain range,the flow velocity of inner gates is reasonable and runner is full during pouring.
