Abstract

The invention relates to the technical field of wax injection molds for precision investment casting, in particular to an inner wall multi-boss large cylindrical shell wax mold integrated forming mold which comprises a lower mold, an upper mold, a first end frame, a second end frame, a first core support, a second core support, a sealing ring assembly, a fastening screw, a first cross beam, a second cross beam and a core strip assembly. According to the wax mold integrated forming mold for the large cylindrical shell with the multiple bosses on the inner wall, the large cylindrical shell with the multiple bosses on the inner wall is horizontally placed to prepare the wax mold, an outer mold is divided into an upper mold body and a lower mold body, automatic mold opening of the outer mold body is achieved through lifting of an upper mold plate of a wax injection machine, and rapid cooling of a thick and large end frame is achieved through an end frame and a cooling water channel on the end frame; rapid drawing of the chaplet is achieved through the chaplet and the draft angle of the chaplet, integrated forming of the large cylindrical shell wax mold with the multiple bosses on the inner wall can be achieved, and the size precision and the preparation efficiency of the wax mold are improved.

Description

technical field [0001] The invention relates to the technical field of wax injection molds for investment precision casting, in particular to an integrated wax mold forming mold for a large cylindrical shell with multiple inner walls and multiple bosses. Background technique [0002] With the continuous improvement of China's industrial manufacturing capacity, aerospace vehicles continue to develop in the direction of hypersonic speed. The size of the cylindrical shell castings is continuously increased, and the inner wall of the cylindrical shell assembly bosses require integrated forming. At the same time, in order to ensure the cylindrical shell The surface finish and dimensional accuracy of the non-machined area of ​​the inner wall of the shell are mainly used in domestic production of cylindrical shell castings. [0003] Due to the large size of the existing cylindrical shell, the wax mold preparation method is mostly used in sections. The cylindrical casting is divided...
