Machining process of mold core

Abstract

The invention discloses a machining process of a mold core. The machining process of the mold core comprises the following steps of material preparation, specifically, a blank made of an SKD61 material is prepared; rough machining, specifically, six faces are machined roughly through a milling machine, allowances are reserved, and a screw hole and a water way are machined; M / C rough machining, specifically, a molding station is roughly formed and an allowance is reserved; thermal treatment, specifically, the material is subjected to thermal treatment to achieve the optimal hardness; grinding, specifically, the six faces are ground until the shape is molded; wire-electrode cutting, specifically, a middle through frame is subjected to wire-electrode cutting; fine machining, specifically, M / C fine machining is conducted; electric discharge machining, specifically, electric discharge machining is conducted and 0.03-0.035 mm is reserved at the glue position; polishing, specifically, mirror polishing is conducted on the glue position; and texturing, specifically, texturing is conducted in the position with the special requirement of the glue face. The machining process is reasonable, few workpieces are damaged, the mechanical machining precision is high, the production efficiency is improved, errors caused by manual operation are avoided, and the product percent of pass is improved.

Description

technical field [0001] The invention relates to a mechanized high-precision mold core processing technology. Background technique [0002] Existing mechanized production is gradually improving, but mechanized gas needs the support of various molds, so the processing requirements for molds are also constantly improving. The processing efficiency, precision, and pass rate of molds will affect the production cost. Due to different industries, products and equipment, the requirements for molds are also various. Therefore, the follow-up processing of most molds often relies on manual labor, which has certain deficiencies in precision and efficiency. Contents of the invention [0003] In view of the above-mentioned existing technical problems, the object of the present invention is to propose a mechanized high-precision mold core processing technology. [0004] The technical solution of the present invention is realized like this: a kind of processing technology of mold core, i...
