Problems solved by technology

[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. 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.

Embodiment Construction

[0017] The processing technology of a kind of mold insert of the present invention, its processing step is as follows:

[0018] (1) Material preparation: prepare the blank of SKD61 material;

[0019] (2) Rough machining: M / C rough machining of six sides, screw holes, waterways, leaving margin;

[0020] (3) Heat treatment: the heat treatment material reaches the optimum hardness; the heat treatment is quenched first: the first stage preheating: 500-550°C, the second stage preheating: 750-800°C, quenching temperature 1000-1050°C, blowing cooling or High-pressure gas cooling; the heat treatment is tempered after quenching: preheating: 300-350 ° C, tempering heating: 550-680 ° C, air cooling to room temperature, tempering three times; the optimal hardness is 50-55HRC;

[0021] (4) Grinding: Grinding and processing six sides, shape forming;

[0022] (5) Wire cutting: wire cutting head forming;

[0023] (6) EDM: precision discharge glue position;

[0024] (7) Electrical discharg...

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
