High-temperature alloy mould and casting and demoulding method thereof

Abstract

The invention discloses a high-temperature alloy mould and a casting and demoulding method of the high-temperature alloy mould. The high-temperature alloy mould comprises an ultrasonic controller, wires, a base and a plurality of mould components, wherein each mould component comprises a mould, an upper mould and a lower mould; a bottom fixed seat and an ultrasonic probe are arranged in the mould, the mould is vertically fixed on the upper surface of the base, the ultrasonic probe is connected with the ultrasonic controller through the wire, and fastened on the upper surface of the base, the bottom fixed seat is further fastened on the upper surface of the base and the ultrasonic probe is wrapped inside the bottom fixed seat, and a hole of which the surface area is smaller than that of the ultrasonic probe is opened at the upper part of the ultrasonic probe, the lower mould is vertically inserted into the internal part of the bottom fixed seat through the hole, and the upper mould is arranged above the lower mould and connected with the lower mould through a clamping buckle. According to the invention, the existing process is improved by adopting an ultrasonic assisted high-temperature casting and double-node mould technology, and the high-temperature alloy mould and the casting and demoulding method of the high-temperature alloy mould are low in cost, simple in process and suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of metal materials, and in particular relates to a high-temperature alloy mold and its casting and demoulding methods. Background technique [0002] With the emergence of rapid solidification furnaces, the rapid solidification method is currently adopted in turbo casting in the automotive turbine industry, and the requirements for superalloys are getting higher and higher. On the one hand, good surface quality is required. The traditional way is to reduce the shrinkage cavity problem in the metal center, and low-temperature casting is adopted, resulting in insufficient surface filling, rough surface, and large waste of material surface processing; The requirements are relatively high. The traditional mold is easy to deform at high temperature, and burrs and scratches will be formed on the surface when demoulding. The uneven surface will also damage the mold. The service life of the general mold is only 1-2 t...

Problems solved by technology

On the one hand, good surface quality is required. The traditional method is to reduce the shrinkage cavity problem in the metal center, and low-temperature casting is adopted, resulting in insufficient surface filling, rough surface, and large waste of material surface processing; The requirements are relatively high. The traditional mold is easy to deform at high temperature, and burrs and scratches will be formed on the surface when demoulding. The uneven surface will also damage the mold. The service life of the general mold is only 1-2 times.
