Problems solved by technology

It is actually found that the quenched mold often has defects such as deformation, blunt sharp corners or sharp corner bruises on the parting surface, which affects the quality of the connection surface between the half-moulds, and then affects the surface quality of the formed parts

Embodiment 1

[0022] Embodiment 1, a split model is made up of left half-mold and right half-mold, change the digital model and move the left half-mold of split model to the left by 0.2mm, and then move 0.2mm between the left half-mold and the right half-mold The gaps in the gaps are filled with entities to form gaps, which become new digital models. Then according to the overall digital model after the change, the upper material is processed by the numerical control machine tool to process the integral model composed of the left half mold, the gap body and the right half mold. After processing and forming, put the whole mold into the quenching furnace to quench to increase the hardness. After the quenching is completed, the model is cut on the wire cutting machine with molybdenum wire at the position of the gap body, and the two parts separated after cutting are the left half-mold and the right half-mold. Finally, the mold surfaces of the left half mold and the right half mold can be used...

Abstract

The invention belongs to the machining technology and relates to a method for machining split quenched pattern dies. The method is characterized by including steps of modifying multiple dies, machining an integral pattern die according to the modified dies, quenching, cutting the pattern die into halves, and polishing. By the method for machining split quenched pattern dies, defects that connecting burrs, damage and R-angle exist at a profile joint between the die halves of the split pattern die transitionally and parting surface is not flat and the like are reduced, and a method of independently manufacturing and quenching the two die halves of the split pattern die is changed into the technical method of integrally manufacturing, quenching and splitting. Machining accuracy of the die halves of the split pattern die is improved, the problems of many machining links and less proneness to coordination are solved, and forming quality is improved.

Description

technical field [0001] The invention belongs to the aviation machinery processing technology, and relates to a method for processing split quenching molds. Background technique [0002] When forming sheet metal parts, molds are needed. Sometimes due to the particularity of the molded parts, the molds that need to be used for molding are in the form of split parts. Half mold composition. If the molded parts are made of hard materials such as stainless steel, the mold used for molding needs to have higher hardness, and then the mold needs to be quenched. Since the mold is not easy to process after quenching, the normal processing method is to quench the mold after the half mold is processed, and then assemble and deliver it for use. It is actually found that the mold after quenching often has defects such as deformation, blunt sharp corners or sharp corner bruises on the parting surface, which affects the quality of the connection surface between the half-moulds, and then af...
