Dynamic balance pouring system of double-layer blade thin-wall guider

Abstract

The invention discloses a dynamic balance pouring system of a double-layer blade thin-wall guider. According to the system, a three-dimensional pouring system taking a sprue as a central axis in cooperation with three layers of transverse pouring gates is adopted, firstly, a first flow of molten alloy is guided to the outer ring position through the first layer of transverse pouring gate at the bottom layer so as to fill an outer ring and an outer-layer blade from bottom to top, then a second flow of molten alloy is guided to the inner ring position through the second layer of transverse pouring gate in the middle so as to fill an inner ring and an inner-layer blade, and finally a third flow of molten alloy is guided to the riser position through the third layer of transverse pouring gateat the top layer for filling. According to the system, mold filling is integrally realized from bottom to top and from inside to outside, temperature gradient can be naturally formed to achieve the purpose of sequential solidification, and particularly, the riser is finally filled and solidified, so that the feeding efficiency is favorably improved, the loosening rejection rate is favorably reduced, risks caused by various defects can be effectively balanced and inhibited, and the pouring requirement of the double-layer blade thin-wall guider is well met.

Description

technical field [0001] The invention relates to the technical field of gating system of a double-blade thin-wall guide, in particular, relates to a dynamic balanced gating system of a double-blade thin-wall guide. Background technique [0002] Such as figure 1 with figure 2 As shown, a certain type of guide is composed of double-layer blades and three concentric rings. It has thin blades and large torsion. The corner radius between the rings is small and the thickness changes sharply. Conventional gating systems are likely to cause problems such as under-casting, cold shut, inclusions, porosity, cracks, and dimensional deformation, and various defects are mutually restrained. Specifically, the above-mentioned double-layer blade thin-walled guider There are several problems when pouring: [0003] 1) The thinnest part of the blade is only 0.2mm, the channel is narrow and the filling is not smooth and the cooling speed is fast, which is easy to cause under-casting and cold...
