Core fixing ring and method for making soluble core of swirler

Abstract

The invention relates to a tool for a making preciously cast soluble core, and a method thereof, and especially relates to a tool for making the soluble core of a swirler, and a method thereof. The method for making the soluble core of the swirler comprises the following steps: 1, placing a core fixing ring in a soluble core die, compacting according to technological parameters to form the soluble core, slightly wholly taking out the soluble core and the core fixing ring, and allowing the soluble core and the core fixing ring to stand on a flat sponge for a period of time; 2, placing the soluble core with the core fixing ring in a wax die, compacting according to technological parameters to form a wax mold, and allowing the wax mold to stand on the flat sponge for a period of time; and 3, putting the wax mold in a core removing pool, removing the core, taking out the ring fixing ring after the core is completely removed, cleaning, and air-drying the core fixing ring. The fracture phenomenon of the soluble core obviously decreases by adopting the tool, the method and the core fixing ring.

Description

technical field [0001] The invention relates to a precision casting soluble core manufacturing tool and method, in particular to a vortex soluble core manufacturing tool and method. Background technique [0002] The dimensional accuracy of the soluble core of the vortex is relatively high. At present, the soluble core of the vortexer is usually pressed and wax molded by conventional tooling and methods. Because the soluble core of the vortexer is thin and the leaf shape is dense, the soluble core often cracks or even breaks and is scrapped during the pressing process, and fractures and dislocations often occur during the subsequent wax mold pressing process, resulting in the throat size of the vortexer wax mold being out of tolerance , thus causing wax molds and even castings to be scrapped. Contents of the invention [0003] (1) Purpose of the invention [0004] The purpose of the invention is to provide a tooling and method for preventing the soluble core of the vorte...
