Gating system for casting alloy standard samples and manufacturing method of mold shell

Abstract

The invention is applicable in the technical field of precision casting of metal materials, and provides a gating system for casting alloy standard samples. A sprue cup, a feeding structure connectedwith the sprue cup, a sprue connected with the feeding structure, a cross gate perpendicular to the sprue and multiple ingates connected with the cross gate are arranged, the shapes of the ingates areconsistent with the shapes of prefabricated standard samples, and the sectional areas of the sprue cup, the feeding structure, the sprue and the cross gate are sequentially and progressively decreased, so that when molten metal is poured from the sprue cup, the gravity difference can be generated, stable mold filling can be achieved, the defects of pores and looseness of castings can be overcome,grains can be refined and equiaxed grains can be increased through improvement of a liquid metal temperature field in the solidification process of the molten metal, defects such as segregation are reduced, the standard samples with relatively-uniform structures are obtained, the multiple standard samples can be obtained through one-time pouring, the casting efficiency is greatly improved, and the production and time costs are saved.
