Dynamic balanced gating system for thin-wall guider with double-layer blades

Abstract

The invention discloses a dynamic balanced pouring system of a double-layer blade thin-walled guider. By adopting a three-dimensional pouring system with a sprue as the central axis and a three-layer runner, first passing through the first runner of the bottom layer Drain the first molten alloy liquid to the outer ring to fill the outer ring and the outer blades from bottom to top, and then drain the second molten alloy liquid to the inner ring through the second runner in the middle to fill the inner ring. Filling with the inner blade, and finally draining the third alloy liquid to the riser for filling through the third runner on the top layer, realizing the overall filling from bottom to top, from inside to outside , which is conducive to the natural formation of a temperature gradient to achieve the purpose of sequential solidification, especially the final filling and solidification of the riser, which is conducive to improving the feeding efficiency and reducing the loose and scrap rate, and can effectively balance and suppress the risks of various defects, which is very good It meets the pouring requirements of the thin-walled guide for double-layer blades.

Description

technical field [0001] The present invention relates to the technical field of casting systems for thin-walled guides with double-layer blades, in particular, to a dynamic balanced casting system for thin-walled guides with double-layered blades. Background technique [0002] like figure 1 and figure 2 As shown, a certain type of guide is composed of double-layer blades and three concentric rings, with thin blades and large torsion. The corner radius between the rings is small, the thickness is thin, and the sudden change is sharp. Conventional gating systems are prone to problems such as under-casting, cold separation, inclusions, looseness, cracks, dimensional deformation, etc., and various defects are mutually restrained and gamed. 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 isolation; ...
