Multi-connected long blade precision casting wax mold combination correction tool

Abstract

The invention discloses a multi-connected long blade precision casting wax mold combination correction tool which comprises a lower plate body and an upper plate body, the upper plate body and the lower plate body are fixedly connected through a stand column, a blade supporting piece is installed on the top face of the upper plate body, a blade wax mold is placed on the blade supporting piece, a through groove is formed in the upper plate body, and a translation seat is slidably connected to the lower plate body; a six-point positioning assembly is mounted on the translation seat and penetrates through the through groove to position and support the blade wax mold; the blade wax molds are supported, corrected and positioned by matching the blade supporting piece with the six-point positioning assembly, the blade wax molds at different positions are supported by sliding the translation seat on the lower plate body, accurate combination of single blade wax molds is facilitated, deformation of the blade wax molds is corrected, meanwhile, secondary deformation of the blade wax molds is avoided, and the production efficiency is improved. The size of the multi-connected blade casting is effectively controlled, the size precision and the qualified rate of the casting are improved, and the production period of the casting is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of investment mold precision casting, in particular to a wax mold combination correction tool for multi-joint long-blade precision castings. Background technique [0002] Medium-sized gas turbine and aero-engine blade parts are generally cast by investment casting. The dimensions of the multi-connected long-blade parts require high precision, and the multi-connected blades are volatile. Due to the complex structure of the parts, the high cost of the overall mold opening, and the difficulty in taking the mold, a single-leaf mold is usually designed, and multiple blades are spliced ​​and combined by tooling. Due to the different structure of each part of the parts, the length of the blade body is too long, and the size and thickness are not uniform, so the blade wax parts will shrink and deform after the mold taking process. Combination, this method takes a long time to combine, the combination efficiency is...

AI Technical Summary

Problems solved by technology

Due to the different structure of each part, the length of the blade body is too long, and the thickness of the size is uneven, so the wax parts of the blade will shrink and deform after the process of taking the mold. Generally, the wax parts must be calibrated by the calibration tool before being processed by the combined tool. Combination, this method takes a long time to combine, the combination efficiency is low, and the straightness of the exhaust side is not easy to control, and secondary deformation is easy to occur, which reduces the assembly accuracy of the wax mold, thereby affecting the dimensional accuracy of the casting, reducing the pass rate of the casting, and increasing The production cycle of castings is shortened, and the production efficiency of enterprises is reduced
