What kind of mold manufacturing process do you know?

In general, the production process of mold production is as follows:

Drawing review -- material preparation -- processing -- mold embryo processing -- mold kernel processing -- electrical processing -- mold parts processing -- testing -- installation -- flying mold -- test piece -- production and manufacturing

One. Mold embryo processing

(1) Processing steps

1. Number;

2.A/B plate processing;

3. Control panel processing;

4. Thimble fixed plate processing;

5. Bottom plate processing.

(2) Key points of processing

1. The serial number should be unified, and the mold should be numbered, which should be consistent with the serial number of the mold embryo and the same orientation, pointing to the installation can be, not easy to fail.

2.A/B plate processing (i.e., dynamic fixed mold frame processing) : A/B plate processing, should ensure that the flatness and flatness of the mold frame is 0.02mm.

3 Control panel processing: milling machine processing, boring into the rubber mouth sleeve hole or processing nozzle hole.

4 thimble fixed plate processing: milling machine processing, thimble plate and B plate with back needle connected to each other, B plate toward the top, top-down drilling pinhole, thimble countersunk head to the opposite bottom end of the thimble plate, calibration, first rough with twist drill, then car knife finishing in time, chamfering.

5. Base plate processing: milling machine processing, line drawing, calibration, milling, chamfering.

(Note: For some molds that need to be strongly pulled and strongly pushed, it is necessary to steadily develop the organization of pulling and strongly pushed, such as adding screw holes on the thimble board)

Two. Mold processing

(1) Processing steps

1. Raw edges;

2. Fine grinding;

3. Milling machine processing;

4. Milling;

5.CNC roughing;

6. Heat treatment process;

7. Fine throwing;

8.CNC finishing;

9. Spark discharge processing;

10. Line cutting (slow wire walking);

11. Save mold.

(2) Key points of processing

1. Rough machining flying six sides: machining on CNC lathe to ensure flatness and flatness, leaving grinding capacity 1.2mm.

2. Fine grinding: large terrazzo processing, grinding a large number of first, with the batch division clamping grinding Chongqing small surface, to ensure the flatness and flatness at 0.05mm, reserving capacity, multilateral 0.6-0.8mm.

3. Milling machine processing: First calibrate the CNC lathe engine to ensure that it is within 0.02mm, calibrate the clamping product workpiece, first process the screw hole, top pin hole, thread hole, insert pin countersunk head open rough hole, machine nozzle or material nozzle hole, separate the cone hole chamfering and then do the drainage port, milling R Angle.

4 milling processing: tapping, play word code.

5.CNC roughing: retain capacity.

6. HRC48-52 for external perm.

7. Finishing: large terrazzo processing to the specific mold frame negative 0.04mm, to ensure the flatness and flatness within 0.02mm.

8.CNC finishing.

9. Spark discharge machining.

10 line cutting (slow wire) precision ±0.005, generally cut a repair.

11. Save the mold, ensure the smoothness, control the mold specification.

12. Processing rubber inlet and exhaust pipe. Under normal conditions, the rubber inlet of zinc alloy material is opened 0.3-0.5 mm, and the exhaust pipe is opened 0.06-0. Millimetre; Aluminum alloy profile opening 0.5-1.2mm, exhaust pipe opening 0.1-0.2; Open the plastic exhaust pipe 0.01-0.02, as wide and as thin as possible.

Three. Mold parts processing

(1) Processing steps

1. Processing of guide slide block;

2. Clamping block processing;

3. Processing of separating cone-feeding rubber sleeve;

4. Insert processing.

(2) Processing technology of guide slide block

1. CNC lathe roughing six sides;

2. Fine throw six sides to the specification;

3. CNC lathe roughing hanging platform;

4. Hang the table fine to the specification, and with the mold line position;

5. The milling machine processes the slope to ensure that the inclination is consistent with the clamping block, leaving the capacity of the flying die;

6. Drill water and diagonal guide holes. The inclined guide hole is 1 mm larger than the dowel pin and chamfered. The inclination of the inclined guide hole should be 2 degrees less than the slope of the guide slide. The inclined guide post hole can also be reprocessed with the die embryo after the die is flown and closed, depending on the different conditions.
