Problems solved by technology

The size of the plastic or wax core support is processed in place at one time. If the size needs to be adjusted, the mold needs to be modified and remanufactured, which is not only costly but also inefficient.

Abstract

The invention discloses a positioning mold and a positioning method for adjusting engine blade ceramic cores, comprising a wax mold upper mold, a wax mold lower mold, and a ceramic core, wherein a wax mold is formed between the wax mold upper mold and the wax mold lower mold chamber, the ceramic core is installed in the wax mold cavity, and the upper mold of the wax mold includes a wax injection port, four width positioning holes, two length positioning holes, and two first height positioning holes; the wax The lower mold is provided with four second height positioning holes; one of the length positioning holes, two width positioning holes on the same side of the wax mold cavity, and one side of the four second height positioning holes are all provided with Lock the bolts. The invention is widely used on hollow turbine blade castings of aviation and aerospace engines, and the effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of investment precision casting, in particular to a positioning mold and a positioning method for adjusting a ceramic core of an engine blade. Background technique [0002] With the increase of the thrust-to-weight ratio of aviation and aerospace engines, the temperature at the front inlet of the turbine continues to increase at an average annual rate of 30°C to 50°C, which makes the temperature and load on the hot-end parts of the engine also continue to increase. Temperature and performance put forward higher requirements. Hollow turbine blades can be produced by investment casting, and air cooling technology is used to increase the working temperature of the blades, so that the blades can work at the melting point of the superalloy. However, the inner cavity of the hollow turbine blade has a complex shape and narrow space (partially below 1mm), and metal molds cannot be used for parting in the investment...
