Abstract

The invention discloses a titanium alloy open-type impeller investment casting method, which comprises the following steps: designing a pouring system wax mold, designing a combined wax mold group, making a mold shell, dewaxing and demolding treatment, pouring molding and post-processing steps , the present invention solves the deformation problem in the investment casting production process of the titanium alloy open impeller by adding support columns to the combined wax mold set and repeatedly flipping the combined wax mold set during the mold shell preparation.

Description

technical field [0001] The invention relates to the field of titanium and titanium alloy investment precision casting, in particular to a titanium alloy open impeller investment precision casting method. Background technique [0002] The titanium alloy impeller includes a disc, a hub and blades. The blades are evenly distributed on the surface of the disc around the axis of the disc. According to its structure, it can be divided into three types: open type, semi-closed type and closed type. The blades of the titanium alloy open impeller are in the shape of a spiral and a curved surface that gradually increases along the arc surface. Usually, investment casting is used. The schematic diagram of the combined wax mold set used in the preparation process is shown in figure 1 , the disc of the impeller is perpendicular to the hook 1 and placed horizontally, the sprue 2 is connected to the runner 5, the inrunner I4 is connected to the hub, and the two inrunners II 3 are connected ...
