1. Processing process arrangement　　

The bottom surface is processed, and the processing volume is guaranteed;
Casting rough reference alignment, 2D and 3D surface allowance inspection;
2D, 3D profile rough machining, non-installation non-working plane machining (including safety platform surface, buffer mounting surface, pressure plate plane, side reference surface);
Before semi-finishing, the side reference plane should be aligned to ensure accuracy;
Semi-finished 2D and 3D surface, finishing all kinds of installation working surfaces (including limit block installation surface and contact surface, insert installation surface and backside, punch installation surface, waste cutter installation surface and backside , Spring mounting surface and contact surface, various stroke limit working surfaces, inclined wedge mounting surface and backside), semi-finishing various guiding surfaces and guiding holes, leaving a margin for finishing process reference holes and height reference surfaces, and recording data;
Inspection and review of processing accuracy;
Fitter inlay process;
Before finishing, align the datum surface of the process datum hole and check the insert margin;
Finishing profile 2D, 3D, side punching profile and hole position, finishing process reference hole and height reference, finishing guide surface and guide hole;
Inspect and review the machining accuracy.

Matters Needing Attention

The process preparation is concise and detailed, and the processing content is expressed as numerically as possible;
The key and difficult points of processing, the craftsmanship should be specially emphasized;
It is necessary to combine processing locations, and the process is clearly expressed;
When the insert needs to be processed separately, pay attention to the process requirements of the processing accuracy;
After the combined processing, the insert parts that need to be processed separately, the process is installed in the combined processing and the benchmark requirements for separate processing;
Springs are the most easily damaged in mold processing, so choose mold springs with long fatigue life.
