The stricter the mold ejector pins processing process, the higher the accuracy

The stricter the mold ejector pins processing process, the higher the accuracy. The following introduces how to improve the accuracy from the processing perspective.

1. The mold core is processed by a high-end machine with an accuracy of 0.02μ;

2. It is best to process the mold core at one time to avoid repeated off the machine, there will be errors each time the lieutenant calibration table is divided;

3. Slow wire for core wire cutting;

4. The core inserts can be processed by a grinder without computer gongs, especially round inserts;

5. The flying mold can not be used with a sanding machine, directly on the flying mold machine;

6. The precision of the mold blank is controlled within 0.02mm, and the normal mold is more than 0.05mm;

7. Three-dimensional full inspection is used for the electrical level of the inner mold steel, and the better computer gongs can be directly inspected on the machine

8. Red copper is used for electrical grade processing, no graphite is used, graphite sparks fast, but it is easy to damage the male, especially thin steel.

The processing accuracy of mold ejector pins requires a complete set of reasonable design and processing flow control to be made, and problems in each link have an impact on the accuracy.
