1. Processing technology of inclined top guide block
1) Wire cutting processing: cut the shape quickly by wire, leaving a grinding machine.

2) Grinding machine processing: grind the hexagon square to ensure accurate outer dimensions.

3) Milling machine processing: threading holes and screw holes.

4) Wire cutting processing: fast wire cutting of inclined top guide holes.

2. Slider seat processing technology
1) Prepare materials.

2) Grinding machine processing: grind the hexagon square to ensure accurate outer dimensions.

3) Milling machine processing: drilling wire holes, drilling and tapping screw holes.

4) Wire cutting processing: fast wire processing of inclined guide post holes.

5) CNC finishing: the dimensions of the forming area are milled accurately.

3. Briquetting process
1) Prepare materials.

2) Milling machine processing: drill screw holes and roughen the forming area (reserve 0.3-0.5 on one side, grinder).

3) Grinding machine processing: grind the hexagon square, grind the outer dimensions accurately, and shape it.

4. Locking block processing technology
1) Prepare materials.

2) Grinding machine processing: grind the hexagon square to ensure accurate outer dimensions.

3) Wire cutting processing: fast wire forming.

4) Milling machine processing: drilling and tapping screw holes.

5. Principles of ejector hole processing
The ejector holes above Φ3 (including Φ3, Φ4, Φ5, Φ6) are processed by milling machine drilling and reaming, the ejector holes below Φ3 or non-standard ejector holes are processed by wire cutting, and the bottom is avoided.

6. Principles of thread hole processing
When various holes require wire cutting and the inner wall circumference is larger than Φ3 (including Φ3), wire holes must be drilled.

7. Trademark processing and molds that require mirror polishing
1) Leave a margin at the trademark after CNC fine milling of the mold core.

2) Wire cutting wire processing: trademark insert hole.

3) Electric discharge processing: the depth of the hanging table is accurate.

4) Equipped with brand core and installation fixture.

5) The margin pulse at the trademark is connected to level.

6) Polishing.

8. Mold base processing technology
1) Milling machine processing: chamfering of the inner frame, drilling of screw holes, ejector pin holes, waterway holes, sprue cup through holes, and inclined top hole through holes.

2) CNC processing: milling of the sprue cup counterbore, inclined top seat hole, guide block hole, row slot, hot runner mold a plate requires CNC processing, and mold foot engraving processing.

9. Rear mold processing technology for mounting brackets with grid-like ribs
The processing of mold ribs behind this type of mounting bracket requires different processing techniques according to different mold categories.

1) For the first type of mold, we directly use integral electrodes to ensure the uniformity of the product.

2) When selecting the processing technology for non-Class I molds, it can be adjusted according to the actual processing volume. The electrode can be made into separate parts or as a whole. If the rib is a through-groove, it can be cut into rough lines first, and then finely trimmed with a grinder.

10. Parts that require wire cutting fixtures or electrodes and batch pulses
For some workpieces (such as the core of a multi-functional two-pin socket), wire cutting fixtures or electrodes are required. The processing flow of batch pulsed workpieces is as follows:

1) CNC produces ranking chart.

2) Cut the wire cutting drawing to process the fixture or electrode according to the size.

3) After the wire cutting process is completed, if the electrode still needs CNC processing, hand the electrode to the CNC and hand the clamp to the fitter.

4) CNC machine the electrodes and produce discharge diagrams.

5) Pulse processing.

6) Polishing.

11. Calculation of support column height
The support column height of the mold base below 3030 is 0.08-0.1mm higher than the mold foot, 3030 is 0.1mm higher, 3535 is 0.1-0.12mm higher, and above 3535 is 0.12-0.15mm higher.

12. Ejection pin processing technology
For ejector pins of Φ2 and above, the cutting length should be left with a grinder, and the grinder will grind the length to the correct size (the fitter will process it by himself), for ejector pins below Φ2 and wire-cut, the dimensions will be accurate. The flat ejector pin and cylinder are cut by wire cutting and the length is left with a grinder, the grinder is used to process and the length and size are ground accurately.
