Problems solved by technology

EDM has two fatal disadvantages: one is that EDM belongs to electrical discharge machining, and its tool electrodes are lossy. In order to ensure the accuracy of the mold cavity, it is necessary to use multiple tool electrodes to process the same cavity, that is, It is time-consuming and doubles the cost, and it is difficult to guarantee the processing accuracy; second, the processing speed of EDM is very slow, so cutting processing (including cutting processing by five-coordinate linkage CNC machining center) has to be used in the mold blank Before quenching, remove most of the allowance first, then harden and then conduct electric discharge machining to improve production efficiency

Abstract

The invention discloses a method for processing a steel mold cavity, which comprises four steps of utilizing the selective laser sintering and forming technology for manufacturing an electrolytic cathode, constructing an electrolytic machining device, constructing an electrolyte system and forming the steel mold cavity. The invention has the beneficial effects that the method uses a rapid prototyping method for manufacturing the electrolytic cathode, compared with the traditional method for manufacturing an electrical discharge machining tool electrode or the electrolytic cathode, the method has the advantages of high efficiency, low cost, high precision and good surface quality; the production efficiency of electrolytic machining is high, which is about 5-10 times of that of the electrical discharge machining and even higher than the production efficiency of cutting machining, and the machining productivity is not limited by the machining precision and the surface roughness; and the method can achieve good surface roughness and machining precision.

Description

technical field [0001] The invention relates to the field of cavity mold processing, in particular to a processing method for a steel mold cavity. Background technique [0002] In today's manufacturing industry, molds (including stamping molds, plastic molds, forging molds, casting molds, metal die-casting molds, powder metallurgy molds, etc.) are important process equipment and an indispensable part to ensure product manufacturing. [0003] Among all kinds of molds, cavity molds of steel (including various special tool steels, alloy steels, and even hard alloys, etc.) are the most difficult to manufacture. With the rapid development of the manufacturing industry, in order to manufacture product parts with complex shapes, high hardness, high strength and strong toughness, the requirements for the precision and surface finish of the mold are getting higher and higher, and the life of the mold is required to be longer and longer. The production cycle is getting shorter and sh...
