Manufacturing method of oversized wax mould

Abstract

The invention discloses a manufacturing method of an oversized wax mould. The method comprises the following steps: S1, the wax mould is equally divided, specifically, the wax mould is equally divided according to the integral structure of the wax mould, so that the structure and the shape of each part of the wax mould are consistent, and a single wax mould is manufactured; S2, wax mould correction is performed, wherein the manufactured single wax mould is placed in a correction mould, and the single wax mould is precisely corrected; S3, wax mould assembling is performed, specifically, the corrected single wax mould is placed in an assembling tool in an abutting mode and is pressed and fixed; and S4, wax mold repairing is conducted, specifically, a gap between every two adjacent single wax molds is bonded and repaired, the whole wax mold is taken down after the bonding seam is shaped, and then the oversized wax mold meeting the required size requirement is obtained. According to the manufactruring method disclosed by the invention, any oversized wax mold can be produced by adopting conventional mold manufacturing equipment, meanwhile, the size of the wax mold can be flexibly adjusted through the assembling tool, the size of the wax mold is ensured by the tool, the precision is high, the consistency is good, the production cost is reduced, and the market competitiveness is greatly improved.

Description

technical field [0001] The invention relates to the technical field of investment casting, in particular to a method for manufacturing a super-large wax pattern. Background technique [0002] In recent years, with the rapid development of aviation, aerospace and other fields, the requirements for dimensional accuracy of many large parts are getting higher and higher, especially for casing and bearing seat parts, investment casting must be used to meet dimensional accuracy Requirements, but the size of such parts is far beyond the limit of conventional investment casting precision casting equipment, and the outline size is large, it is very difficult to punch the wax mold as a whole, and the surface quality is also difficult to guarantee. The existing precision investment casting Wax casting molds are pressed as a whole, limited by the size of the equipment and the fluidity of the wax material, it is impossible to press the wax molds with a size beyond the limit range of the ...

[0002] In recent years, with the rapid development of aviation, aerospace and other fields, the requirements for dimensional accuracy of many large parts are getting higher and higher, especially for casing and bearing seat parts, investment casting must be used to meet dimensional accuracy Requirements, but the size of such parts is far beyond the limit of conventional investment casting precision casting equipment, and the outline size is large, it is very difficult to punch the wax mold as a whole, and the surface quality is also difficult to guarantee. The existing precision investment casting Casting wax molds are pressed as a whole, limited by the size of the equipment and the fluidity of the wax material, it is impossible to press the wax molds with a size beyond the limit range of the equipment, and when the mold shrinks and is placed incorrectly, the adjustment of the size must be achieved by repairing the mold, which is inefficient
