Mold making process

Author: MULAN –Plastic Molding Manufacturer

The mold making process is as follows: drawing review, material preparation, processing, mold base processing, mold core processing, electrode processing, mold parts processing, inspection, assembly, flying mold, mold testing, production Contact: Mr. Tang. 13825769150A: Mold base processing: 1 type numbering, 2A/B plate processing, 3 panel processing, 4 needle fixed plate processing, 5 bottom plate processing B: Mold core worker: 1 flashing, 2 rough grinding, 3 milling machine processing, 4 fitter Processing, 5CNC rough machining, 6 heat treatment, 7 fine warehouse, 8CNC finishing, 9 electric discharge machining, 10 mold saving C: Mold parts processing: 1 slider processing, 2 compression block processing, 3 split flow gate sleeve processing, 4 Insert processing Mold base processing details 1. The numbering should be uniform, and the mold core should also be numbered. It should be consistent with the number on the mold base and in the same direction. It is easy to make mistakes during assembly. 2. A/B board processing (that is, the processing of movable and fixed mold frames), a: A/B board processing should ensure that the parallelism and verticality of the mold frame are 0.02mm, b: milling machine processing: screw holes, water delivery holes, top Pinhole, machine nozzle hole, chamfer c; fitter processing: tapping, trimming.

3. Panel processing: iron bed processing boring machine nozzle hole or processing material nozzle hole 4. Ejector fixed plate processing: milling machine processing: thimble plate and B plate are connected with back needles, B plate faces upward, and thimble holes are drilled from top to bottom , The countersunk head of the thimble needs to turn the bottom of the thimble plate upside down, correct it, first process it with a drill bit, and then use a milling cutter to finish it in place and chamfer. 5. Bottom plate processing: milling machine processing; scribing, calibration, boring, chamfering, (Note: Some molds need to be strengthened to pull the surface and the top should be strengthened, such as adding holes on the thimble plate) mold core Processing details 1) Gongfei six sides: processed on a milling machine to ensure verticality and parallelism, leaving a grinding allowance of 1.2mm Perpendicularity and parallelism at 0.05mm, leaving a margin of 0.6-0.8mm on both sides Thread the thread hole, set the countersunk head of the needle to make thick, machine nozzle or material nozzle hole, chamfer the taper hole of the shunt, then make the far water hole, and mill the R angle. 4) Fitter processing: tapping, typing code 5) CNC rough processing 6) heat treatment HRC48-527) fine book; large water mill processing to minus 0.04mm than the mold frame, to ensure that the parallelism and verticality are within 0.02mm8 ) CNC finishing 9) EDM 10) Save mold, ensure smoothness, and control cavity size.

11) Process inlet gate, exhaust, zinc alloy under normal circumstances gate opening 0.3-0.5mm, exhaust opening 0.06-0.1mm. aluminum alloy gate opening 0.5-1.2mm exhaust opening 0.1-0.2, plastic cross The exhaust is opened at 0.01-0.02, try to be wider and thinner. Contact 13825769150 Mr. Tang.
