Mold manufacturing design processing process

the 1. mold manufacturing process is as follows:

-drawing review-material preparation-processing-mold base processing-mold core processing-electrode processing-mold part processing-inspection-assembly-flying mold-mold test-production.

(1) mold base processing:(2) mold core processing (3) mold parts processing and numbering A/B plate processing panel processing thimble fixed plate processing bottom plate processing flash rough grinding milling machine processing fitter processing CNC rough processing heat treatment fine grinding CNC finishing EDM mold slider processing compression block processing shunt cone sprue sleeve processing insert processing

(1) The numbering shall be unified, and the mold core shall also be numbered, which shall be consistent with the number on the mold base and in the same direction. It is not easy to make mistakes when aligning during assembly.

(2)A/B plate processing (I .e. dynamic fixed mold frame processing) A/B plate processing shall ensure that the parallelism and verticality of the mold frame are 0.02mm milling machine processing: screw hole, water transport hole, top pinhole, machine nozzle hole, chamfering fitter processing: tapping, burr trimming

(3) panel processing: milling machine processing boring machine nozzle hole or processing material nozzle hole.

(4) Processing of thimble fixing plate: milling machine processing: thimble plate and plate B are connected with return needle, plate B faces upward, and the top needle hole is drilled from top to bottom. The thimble countersunk head needs to turn the thimble plate upside down and correct it. Rough machining with a drill bit first, then finish machining in place and chamfer with a milling cutter.

(5) bottom plate processing: milling machine processing: scribing, correction, boring, chamfering. (Note: For some molds that need strong pulling and strong pushing, a strong pulling and strong pushing mechanism should be added, such as drilling screw holes on the thimble plate)

the 3. core processing details rough machining fly six sides:

is processed on a milling machine to ensure verticality and parallelism, leaving a grinding allowance of 1.2mm for coarse grinding: large water mill processing, grinding the large surface first, clamping the grinding small surface with a batch of companies, ensuring verticality and parallelism at 0.05mm, leaving a margin of bilateral 0.6-0.8mm.

milling machine processing: first calibrate the head of the milling machine to ensure that it is within 0.02mm, calibrate and compress the workpiece, first process the screw hole, top needle hole, thread hole, insert needle countersunk head, machine nozzle or material nozzle hole, shunt cone hole chamfer and then water transport hole, milling r angle fitter processing: tapping, typing code CNC rough machining, external heat treatment HRC48-52 grinding; Large water mill processing to minus 0.04mm than mold frame, ensure parallelism and verticality within 0.02mm CNC finishing EDM mold saving, ensure smoothness, control cavity size processing gate, exhaust, zinc alloy 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 exhaust opening 0.01-0.02, as wide as possible, a little thinner

First, the milling machine roughs the six sides and grinds the six sides to the size requirements. The milling machine roughs the hanging table and grinds the inclined plane with the milling machine to ensure that the inclination is consistent with the pressing block. The allowance is left for the flying die to drill water and the inclined guide hole. The inclined guide post hole is 1mm larger than the guide post and chamfered. The inclination of the inclined guide post hole should be 2 degrees smaller than the inclined slide block. The inclined guide post hole can also be reprocessed together with the mold base after the mold is closed and mounted, depending on different situations.
