Mold processing flow
Process flow arrangement
1. Bottom surface processing and processing quantity guarantee;
2. Casting blank datum alignment, 2D and 3D profile allowance inspection;
3. Rough machining of 2D and 3D profiles, machining of non installation and non working planes (including safety platform surface, buffer mounting surface, pressing plate plane and side datum plane);
4. Before semi finishing, the side reference surface shall be correctly located to ensure accuracy;
5. Semi finish 2D and 3D profiles, finish all kinds of installation working surfaces (including the installation surface and contact surface of the limit block, the installation surface and back side of the insert, the installation surface of the punch, the installation surface and back side of the waste cutter, the installation surface and contact surface of the spring, all kinds of travel limit working surfaces, the installation surface and back side of the wedge), semi finish all kinds of guide surfaces and guide holes, leave margin for finishing the process reference holes and height reference surfaces, and record the data;
6. Inspect and recheck the machining accuracy;
7. Bench worker inlaying process;
8. Before finishing, align the datum plane of the process datum hole and check the allowance of the insert;
9. Finish machining profile 2D and 3D, side punching profile and hole location, finish machining process datum hole and height datum, finish machining guide surface and guide hole;
10. Check and recheck the machining accuracy.
