METHOD AND APPARATUS FOR PRODUCING WAX MODEL CONTAINING PRECISION CASTING CORES

摘要

Disclosed are a method and a device for manufacturing a wax model which is used in a precision casting process and includes a core. According to one embodiment of the present invention, the method for manufacturing the wax model including the core for precision casting comprises: a rubber mold manufacturing step of manufacturing a rubber mold made of a rubber material and having a wax model molding space corresponding to a shape of a target object therein; a core manufacturing step of manufacturing a core using a three-dimensional printing equipment; a wax injection step of injecting molten wax after fixing the core manufactured in the core manufacturing step to a designated location inside the rubber mold manufactured in the rubber mold manufacturing step; and wax model extraction step of extracting the wax model with the core inserted in the rubber mold when the wax is solidified.
