Hardware mold processing process arrangement:

1, bottom processing, processing quantity guarantee;

2. Casting blank datum alignment, 2D and 3D profile allowance check;

3. 2D and 3D surface rough processing, non-installation and non-working surface processing (including safety platform surface, buffer mounting surface, pressure plate plane, side datum surface);

4. Correct precision of side datum surface should be found before semi-finishing;

5, semi-finishing 2D, 3D surface, finishing all kinds of installation face (including limit block installation surface and contact surface, insert installation surface and against the back, punch installation surface, waste cutter installation surface and against the back, spring installation surface and contact surface, all kinds of travel limit working surface, oblique wedge installation surface and against the back), semi-finishing all kinds of guide surface, guide hole, Reserve the finishing process reference hole and height reference surface, and record the data;

6. Check and review the machining accuracy;

7. Fitter inlaying process;

8. Before finishing, straighten the datum surface of the process reference hole and check the allowance of the insert;

9. Finishing surface 2D, 3D, side punching surface and hole position, precision mold processing technology reference hole and height reference, finishing guide surface and guide hole;

10. Check and review the precision of hardware mould processing.

Requirements for precision mold processing:

First, the product specifications are high precision, small dimensional tolerance, both high precision specification limits;

Two, the repeated precision of the product is high, to have a day. Month. Year size reliability;

Three, mold shell material is good, stiffness is sufficient. The dimensional precision of the concave die. High accuracy between smoothness and templates;

Four, choose high precision plastic machine instead of basic plastic machine;

5, the selection of high precision forming processing technology;

Six, the selection of raw materials into high precision forming.
