Abstract

The invention discloses a bottom gating system for a guider. The bottom gating system comprises a sprue cup, wherein the lower end of the sprue cup communicates with a sprue which is vertically arranged; the bottom end of the sprue communicates with a cross gate assembly which is horizontally arranged; the cross gate assembly is used for carrying out diversion and slag stopping on mold filling liquid filled by the sprue in order to remain slag inclusion mixed in the mold filling liquid in the cross gate assembly; and the cross gate assembly is further used for rectifying the mold filling liquid in order to enable the mold filling liquid to be injected stably. The cross gate assembly communicates with mold filling pouring gate assemblies; the mold filling pouring gate assemblies are arranged above the cross gate assembly; and each mold filling pouring gate assembly is separately arranged on the inner side of an inner ring mold shell and the outer side of an outer ring mold shell of a guider mold shell and respectively communicates with the inner ring mold shell and the outer ring mold shell, so that the mold filling liquid after slag stopping and rectifying in the cross gate assembly is stably injected into the inner ring mold shell and the outer ring mold shell through the mold filling pouring gate assembly.

Description

technical field [0001] The invention relates to the technical field of precision casting, in particular to a guider bottom pour type pouring system. Background technique [0002] Most of the existing pouring systems for precision casting guides use top injection or top side injection (such as the pouring system of the patent 201710103137.3 integral casting guide) or top-bottom hybrid (such as the bottom injection of the patent 201810663928.6 blade vertical guide pouring system and pouring method), the high-temperature filling liquid fills the mold from top to bottom, and directly flushes the mold shell of the guide casting. [0003] Since the transition R between the inner ring and the airfoil of the casting mold shell and the transition R between the outer ring and the airfoil are weak areas of the shell, they are directly washed by the filling liquid, and it is easy to generate slag inclusions, and these slag inclusions After the filling liquid is filled, it is mostly con...
