Abstract

The invention discloses a wax mold casting technology and belongs to the technical field of wax mold casting. The technology comprises the following steps that firstly, a wax mold is manufactured, wherein the shape of the wax mold is consistent with that of a casting; secondly, a reinforcing agent is sprayed to the surface of the wax mold; thirdly, the wax mold is put into a large pot containing clean water to be boiled; fourthly, a shell mold is sleeved with a fixing shell, and dry sand is added between the shell mold and the fixing shell for fixing the shell mold; fifthly, the shell mold obtained in the fourth step is dried; and sixthly, smelted molten metal is poured into the shell mold, then cooling and shelling are conducted, and the molded casting is obtained. The surface quality of the casting is good, and the precision is high; a wax mold shell is high in strength and is not likely to be damaged, and the modeling success rate is high; and processes of the wax mold casting technology are simple, and the labor intensity is low.

Description

technical field [0001] The invention belongs to the technical field of wax pattern casting, and in particular relates to a wax pattern casting process. Background technique [0002] Wax patterns are a common casting method. The surface quality of the casting is poor and the precision is low when the existing wax mold is cast; Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a wax mold casting process with high casting quality and high strength of the wax mold shell. [0004] In order to solve the above problems, a wax pattern casting process according to the present invention is composed of the following steps: [0005] (1) Make a wax mold consistent with the shape of the casting; [0006] (2) Apply a strengthening agent on the surface of the wax model, and then dry it at a temperature of 70-90°C, a drying time of 3-5 hours, and a drying wind speed of 1.5-1.9 m / s; [0007] (3) Putting the wax mold in a large p...
