Process control of mold finishing

The general guiding idea for the processing of precision mold parts is to carry out adaptive processing for different mold parts, different materials, different shapes and different technical requirements. There are many selective solutions. However, achieving the best processing effect and economy through control of the processing process is our focus. According to the appearance and shape of precision mold parts, the parts can be mainly divided into three categories: shafts, discs, plates and molded heterogeneous parts. The process of these three types of parts is generally: rough machining-semi-finishing-(quenching, conditioning)-precision grinding-electrical machining-fitter trimming-assembly processing.

1. Heat treatment of precision mold parts

2. Precision mold parts grinding and processing

3. Electric processing of precision mold parts

4. Surface treatment of precision mold parts

The contents of molding surface treatment include no pores on the steel surface, uniform hardness, small differences in anisotropic properties, low inclusions, and places where stress concentration such as knife marks and grinding marks are left on the surface of the part during processing. Therefore, after the processing is completed, the surface of the parts needs to be strengthened, and hidden dangers in processing can be dealt with through mechanical polishing, bench grinding, and polishing. Blunt unnecessary edges, sharp corners, and openings of the workpiece. Generally, there will be a modified hardened layer of about 6 to 10 μm on the electrically machined surface, which is gray-white in color. This layer is brittle and contains residual stress. The hardened layer must be fully eliminated before use. The method is to polish the surface and remove the hardened layer. To obtain high-quality polishing effects, the material, shape, hardness of the workpiece and the surface quality of the cutting process must be fully considered. High-quality polishing tools, high-quality polishing materials, correct polishing procedures, and rigorous personnel are necessary. Quality, good clean environment.

5. Assembly of precision mold parts

During the grinding and electrical machining processes, the workpiece will be magnetized to a certain extent and has weak magnetic force, which can easily absorb some small debris. Therefore, before assembly, the workpiece must be fully demagnetized and the surface cleaned with ethyl acetate.

During assembly:

(1) First understand the assembly drawing and assemble various parts; 

(2) List the assembly sequence of each component; 

(3) Check the dimensional accuracy of each component and clarify the coordination requirements; 

(4) ) Get the required tools, and then start assembling the mold;

(5) First install the guide pillars, guide sleeves, and cavity forming block components of the mold base; (6) Combine the template with the punch and concave mold, and add a trace amount Adjust the position of each plate; 

(7) Open and close the mold to check whether the mold action is reliable.

What should we pay attention to in the process flow of hardware precision mold processing?

1. Bottom surface processing, processing volume guaranteed;

2. Casting blank benchmark alignment, 2D and 3D profile margin inspection;

3. Rough machining of 2D and 3D profiles, and machining of non-installation and non-working planes (including safety platform surface, buffer installation surface, pressure plate plane, and side reference plane);

4. Before semi-finishing, the correct accuracy of the side reference plane must be found;

5. Semi-finishing of 2D and 3D profiles, and finishing of various installation working surfaces (including limit block installation surface and contact surface, insert block installation surface and backrest surface, punch installation surface, scrap cutter installation surface and backrest surface , spring mounting surface and contact surface, various stroke limit working surfaces, wedge mounting surface and backrest surface), semi-finishing various guide surfaces and guide holes, leaving a margin for finishing the process reference hole and height reference surface, and recording data;

6. Inspect and review the processing accuracy;

7. Fitter and inlaying process;

8. Before finishing, align the datum plane of the process datum hole and check the insert allowance;

9. Finishing 2D and 3D profiles, side punching profiles and hole locations, precision mold processing technology reference holes and height benchmarks, finishing guide surfaces and guide holes;

10. Inspect and review the processing accuracy of hardware molds.

Things to note:

1. The process preparation should be concise and detailed, and the processing content should be expressed numerically as much as possible;

2. Special emphasis should be placed on the key and difficult points of processing;

3. The processing parts need to be combined and the process clearly expressed;

4. When the insert needs to be processed separately, pay attention to the process requirements for processing accuracy;

5. For the insert parts that need to be processed separately after combined processing, the benchmark requirements for separate processing of process installation during combined processing;

Spring is the most easily damaged in precision mold processing, so it is necessary to choose mold springs with long fatigue life.
