The technological process of mold manufacturing

Do you know the technological process of injection mold manufacturing?

Let us supplement these information for you.

1. Mold base processing

 1)Numbering

 2)A/B plate processing

 3)Panel processing

 4)Ejector retainer plate processing

 5)Plate processing


2. Mold core processing

 1)Flashing

 2)Rough grinding

 3)Milling machining

 4)Benching

 5)CNC rough processing

 6)Hot treatment

 7)Accurate grinding

 8)CNC finishing processing

 9)EDM

 10)WEDM

 11)Polishing


3.Mold part manufacturing

 1)Slider processing

 2)Compaction block machining

 3)Shunt cone shell machining

 4)Insert processing


4.The detail of mold base processing

 1)The number shall be uniform, and the mold core shall be numbered, which shall be consistent with the number on the mold shelf and in the same direction. It is not easy to make mistakes when assembling

 2)The A/ B plate processing

    A.A/B plate machining shall ensure that the parallelism and perpendicularity of the mold frame shall be 0.02mm

    B.Milling machine: screw holes, water holes, pin holes, nose holes, chamfering

    C.Benching: tapping teeth, trimming the rough edges

 3)Face plate processing: milling machine processing boring machine mouth hole or processing material mouth hole

 4)Thimble fixed plate machining: milling machine machining: the thimble plate and B plate are connected with the return pin, the B plate surface is upward, and the top hole is drilled from top to bottom

 5)Plate processing:  processing: milling machine processing: marking, correction, boring, chamfering


5.Mold core machining details

 1)Rough processing of six - sided: in the milling machine processing, to ensure the vertical and parallel degree, with grinding allowance of 1.2mm

 2)Rough grinding: for large water milling, grind the large surface first, and clip the small surface with the batch to ensure the perpendicularity and smoothness at 0.05mm, and leave a margin of 0.6-0.8mm on both sides

 3) Milling machine head: first, correct the milling machine head within 0.02mm, correct the pressing workpiece, first process the screw hole, pin hole, thread hole, insert pin sink hole, machine mouth or feed mouth hole, split taper hole chamfer and then do water hole, milling R Angle

 4) Benching processing: tapping teeth, typing code

 5) CNC rough processing: remaining margin

 6) Hot treatment: HRC48-52

 7) Finishing grinding;The big water mill is processed to 0.04mm less than the mold frame, and the parallelism and verticality shall be within 0.02mm

 8) CNC finishing processing

 9) EDM

10) Line cutting (slow wire) precision ± 0.005mm

11)Polishing: Ensure smooth finish and control cavity size

12)Generally, the gate and exhaust for processing are 0.3-0.5mm, 0.06-0.1mm, 0.5-1.2mm for aluminum alloy, 0.1-0.2 and 0.01-0.02 for plastic, as wide and thin as possible


6.Slider processing

 1) First milling machine rough processing for six sides

 2) Finishing grinding to size requirement

 3) Milling machine rough machining hanging table

 4) The mounting table is ground to the size requirement and matched with the horizontal sliding of the formwork

 5) Milling machine machining the bevel, ensure that the slope and the compaction block consistent, leaving

 6) Drill water and oblique guide hole, the slant guide column hole is 1 mm larger than the guide column, and chamfer Angle, the slant guide column hole slope should be less than the slider slope 2 degrees of slant guide column hole can fly good die on the die after re-processing with the die frame, according to different conditions
