Embodiment 1

[0037] refer to Figure 1-5 Shown is the preferred embodiment provided by the present invention.

[0038] A high-precision mold production process, specifically comprising the following steps:

[0039] S1. Order material / mold base: preliminarily screen out the mold base material, and perform preliminary processing on the mold base material, and remove the mold base material with large internal particles;

[0040] S2. Rough cutting: process the mold base material with machine tools, and process the general shape of the mold, and leave a margin around the mold;

[0041] S3. Pre-processing: heat treatment is carried out on the mold obtained in S2, after the heat treatment is completed, fine grinding is carried out, and the side wall is measured after the fine grinding is completed to ensure the accuracy;

[0042] S4. Wire cutting process: use the continuously moving electrode wire as the electrode, perform pulse spark discharge on the workpiece to remove metal, cut and shape, a...

Abstract

The invention relates to the technical field of mold production and manufacturing, and discloses a high-precision mold production process. The production process specifically comprises the following steps that S1 material/mold base ordering is conducted, specifically, a mold base material is preliminarily screened out, and is preliminary machined, so that a mold base material internally with largeparticles is removed; and S2, roughing is conducted, specifically, the mold base material is machined through a machine tool, the approximate shape of the mold is machined out, and a margin is reserved on the periphery of the mold. According to the production process, procedures are simple and convenient, used equipment is mostly a numerical control lathe, the machining process is controllable, wire cutting treatment and computerized numerical control machine treatment in the treatment procedures are gathered on the same equipment for treatment, when the numerical control milling machine is used for machining, high-precision machining is conducted by utilizing primary electric spark and intermediate electric spark, technical personnel conduct detection by utilizing 3D scanning detection and 2D detection, so that the size errors of an insert hole and a slide tunnel are minimized.

Description

technical field [0001] The invention relates to the technical field of mold production and manufacturing, in particular to a high-precision mold production process. Background technique [0002] Mold is a kind of various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, stretching, etc. to obtain the required products. Specifically, molds are used to shape articles The tools are composed of various parts, and different types of molds have different structures. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Therefore, the mold is an important tool in industrial production. [0003] Traditional shunt combination mold processing process: blank processing → quenching and tempering → upper and lower mold matching → EDM sleeve machining (rough and fine) → honing and polishing → surface hardening → finished ...
