Problems solved by technology

[0004] The purpose of the present invention is to provide a high-precision mold production process, which has a simple process, and the equipment used is mostly a numerical control lathe, and the processing process is controllable, and the wire cutting processing and computer processing in the processing process are gathered in the same equipment On the CNC milling machine, the primary EDM and the final EDM are used for high-precision machining, and the technicians use 3D scanning detection and 2D detection to determine the size of the insert hole and the row tunnel. The advantage of reducing the error to the minimum solves the problem that the processing of the shunt composite mold is greatly affected by the machining accuracy of the electrode, the positioning accuracy of the sleeve punching process, and the control of the translational amount. The problem of poor control of parameters

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 present invention relates to the technical field of mold production and manufacturing, and discloses a high-precision mold production process, which specifically includes the following steps: S1. Mold base material with large particles; 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. The process of the present invention is simple and convenient, and the equipment used is mostly a numerical control lathe, the processing process is controllable, and the wire cutting processing and the computer gong processing in the processing process are gathered on the same equipment for processing. EDM and final EDM are used for high-precision machining, and technicians use 3D scanning inspection and 2D inspection to minimize the dimensional error of insert holes and row tunnels.

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 ...
