Abstract

The invention provides a spiral upper cone casting mold and process, and belongs to the technical field of casting. The spiral upper cone casting mold comprises a mold core forming portion used for manufacturing blade mold cores, and a wax mold forming portion used for accommodating a plurality of wax cores and used for manufacturing a spiral upper cone wax mold. According to the spiral upper conecasting mold, the spiral upper cone wax mold is divided into a plurality of equal portions, then the blade mold cores with the upper portions provided with forming grooves matched with spiral upper cone blades in shape are manufactured through the mold core forming portion, the blade mold cores are placed in the wax mold forming portion according to the shape of a spiral upper cone, then wax liquid is injected into the wax mold forming portion, and the spiral upper cone wax mold is formed through one-time injection molding. The circumstance that the spiral upper cone is divided into multipleportions, and then all portions of the wax mold are spliced to form a complete spiral upper cone wax mold is avoided, the size precision between all the portions of the spiral upper cone is more accurate, and meanwhile, the deformation amount of the wax mold is reduced.

Description

technical field [0001] The invention belongs to the technical field of casting, and more specifically relates to a spiral upper cone casting mold and technology. Background technique [0002] The spiral upper cone is an important component of the vacuum pump, which is mainly composed of an upper sleeve and a lower sleeve, and a plurality of spiral blades arranged between the upper sleeve and the lower sleeve and arranged at intervals from each other. The diameters of the upper sleeve and the lower sleeve are different, and the helical blades are arranged obliquely in the axial direction of the upper sleeve and the lower sleeve, so that the helical upper cone has a conical cylindrical shape as a whole. In the casting process of the spiral upper cone, it is usually necessary to make a wax mold with the same shape as the spiral upper cone. Because the structure of the spiral upper cone is relatively complicated, the existing spiral upper cone wax mold is usually made of a spira...
