Abstract

The invention discloses a processing technology for a mold insert. The processing technology includes the following steps that (1) material preparation is carried out, specifically, a blank made of an SKD61 material is prepared; (2) rough machining is conducted, specifically, six surfaces, a bolt hole and a water path are roughly machined through a machining center (M/C), and margins are reserved; (3) heat treatment is conducted, specifically, the material is subjected to heat treatment, and thus the optimal hardness is obtained; (4) grinding is conducted, specifically, the six surfaces are ground, and the shape is formed; (5) wire cutting is conducted, specifically, the head is formed through wire cutting; (6) electrical discharge machining is conducted, specifically, precision discharge is conducted on a rubber position; and (7) electrical discharge machining is conducted, specifically, precision mirror surface discharge is conducted on a gate. The processing technology is reasonable, few workpieces are damaged, the mechanized processing precision is high, production efficiency is improved, errors caused by manual operation are avoided, and the product percent of pass is increased.

Description

technical field [0001] The invention relates to a mechanized and high-precision machining process for mold inserts. Background technique [0002] The 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 cost of production. Different industries, products, and equipment have various requirements for molds. 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 technical problems, the object of the present invention is to propose a mechanized, high-precision mold insert processing technology. [0004] The technical solution of the present invention is achieved in this way: a kind of processing technology of die inserting, it...
