A mold assembly tool for a single blade wax mold of a turbine guide

Abstract

The invention discloses a mold-assembling tooling for a turbine guider single-blade wax mold, which comprises a wax mold fitted between an inner positioning block and an outer positioning block, the inner positioning block and the outer positioning block are installed on a track base, And it can move horizontally relative to the track base to clamp, position and release the wax mold; the non-clamping ends of the inner and outer positioning blocks are connected with the elastic mechanism to realize the inner and outer positioning blocks The elastic clamping and reset of the track base; the lower end of the track base is equipped with a rotating handle, which can rotate around the axis; the track base is equipped with an ejection structure that can move up and down. The structure is in contact with the inner positioning block and the outer positioning block in the form of an inclined surface, and the ejection structure and the rotating handle are in contact with a helical surface, and the ejecting structure moves up and down under the rotation of the rotating handle. The mold set tool can accurately and efficiently combine a group of individual blade wax patterns into a full ring guide wax pattern.

Description

technical field [0001] The invention relates to the fields of aerodynamic devices and gas turbine guides, in particular to a tool for forming a single-blade wax model of a turbine guide. Background technique [0002] Turbine guide is an important high-temperature part of aerodynamic power plant and gas turbine. It is located behind the combustion chamber and before the turbines at all levels to withstand the impact of high-temperature and high-pressure gas. [0003] At present, the turbine guide is composed of an inner ring, an outer ring and multiple blades, and is produced by precision investment casting. The initial process of the casting process is to make a wax mold module. Now the wax mold manufacturing generally includes the overall mold opening and a single blade. Mold. [0004] For the form of integral mold opening, the design is difficult, the gap between the blades is small, the mold parts between the blades are too small, and there are many sharp edges, which wi...

Problems solved by technology

[0004] For the form of integral mold opening, the design is difficult, the gap between the blades is small, the mold parts between the blades are too small, and there are many sharp edges, which will cause the mold to be damaged quickly and the mold maintenance cost is high later.

At the same time, for guides with cavities, there is a high probability of breaking the ceramic core during the process of wax pressing. However, for guides used in the whole ring, any breakage of the ceramic core will cause the whole ring to be scrapped, and the overall mold opening cost is too high
