Precision mold processing process is to enter the measurement stage, people need to record each size clearly according to customer requirements, and these sizes are marked out through the design drawing, so that they can enter the next step process, in the process of processing these molds, people need to complete different goals step by step, in order to produce a precision mold. The following Xiaobian share precision mold processing process and common problem solving content, welcome to read!

Precision mold processing process:

1. Bottom surface processing, processing quantity is guaranteed.

2. Benchmark the casting blank and check the 2D margin and 3D profile.

3.23D surface rough processing, non-installation and non-working surface processing (including safety platform surface, bumper mounting surface, platen surface, side datum surface).

4. Align side datum to ensure accuracy before semi-finishing.

5. Semi-finishing 2D and 3D profiles, finishing all kinds of mounting surfaces (including stopper mounting surface and contact surface, blade mounting surface and back, punch mounting surface, scraper mounting surface and back, spring mounting surface and contact surface, various travel limit working surface, wedge mounting surface and back), semi-finishing all kinds of guide surface and guide hole, Reserve allowance for finishing process reference hole and height reference surface and record data.

6. Check and recheck the machining accuracy.

7. Fitter insertion process.

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

9. Finishing 2D profile and 3D profile, side punching profile and hole position, precision die machining process reference hole and height reference, finishing guide surface and guide hole.

10. Check and recheck machining accuracy.

What are the common problems of precision mold processing?

Precision stamping deformation, burr, etc.; Cracks, warps, surface abrasions, angular deformation, etc.; Flange wrinkle, deep drawing wall wrinkle, deep drawing wall damage, crack, etc. Flanging crack, swelling uneven, etc. Are often encountered in the processing of precision mold problems. So how should these problems be solved?

Firstly, mold design should have reasonable gap value, fillet radius and machining accuracy. When designing the bending die, effective measures should be taken to reduce the springback and subtract the springback amount from the die. Reasonable rounded corners are designed to prevent bending and cracking. In deep drawing, the holder ring is used to prevent wrinkling, and the pressure should be moderate; Reduce drawing resistance with appropriate lubrication to prevent the mold from sticking or making the workpiece pull through; Use professional stamping oil in line with process requirements.
