Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, to solve the problem of insufficient pouring of the metal solution in the core when processing such small and long parts such as blades of turbine engines, it is easy to generate pores on the surface of the parts, affecting the The overall strength and service life of the parts, thus seriously reducing the processing quality of the parts, the invention proposes an investment casting core

Abstract

The invention relates to the technical field of investment casting machining, in particular to an investment casting core. The investment casting core comprises a shell, a transmission unit and mold units. The transmission unit is mounted in the shell. The transmission unit comprises a motor, a conveying belt, a transmission wheel and a fixing rod. The mold units comprise outer molds and cores. Apouring unit is arranged at the position of a sprue gate. The pouring unit comprises a sealing magnetic strip, a guide pipe and a pouring head. Through the cooperation of the shell, the transmission unit and the mold units, the core swing is achieved, and therefore flow of a metal solution in the cores is accelerated. The cores can be fully filled with the metal solution before the metal solutionis cooled, thus, the situation that the metal solution starts to be cooled before reaching a designated position as the internal structures of the cores are too long is effectively avoided, the problems of air holes and bubbles existing in the surfaces of parts in the investment casting machining process are reduced, and therefore the machining quality of the parts is effectively improved.

Description

technical field [0001] The invention relates to the technical field of investment casting processing, in particular to an investment casting core. Background technique [0002] Investment casting, also known as lost wax casting, includes processes such as wax pressing, wax repairing, tree formation, dipping, melting wax, casting molten metal and post-processing. Lost wax casting is to use wax to make a wax mold of the part to be cast, and then coat the wax mold with mud, which is the mud mold. After the clay mold dries, it is placed in hot water to melt the inner wax mold. Take out the clay mold that has melted the wax mold and bake it into a pottery mold. Once roasted. Generally, when the mud mold is made, the sprue is left, and then the molten metal is poured into the sprue, and after cooling, the required parts are made. The types of alloys that can be produced by investment casting include carbon steel, alloy steel, heat-resistant alloy, stainless steel, precision al...
