(Note: Some molds need to be strong pull top to do strong pull top mechanism, such as on the Thimble board with drilling screws hole) die core processing details 1) Roughing flying Six sides: Machining on the milling machine, to ensure the verticality and parallelism, leave the grinding allowance of 1.2mm 2) Coarse grinding: Large-scale grinding machine, first milling large surface, with a batch of clamps to tighten the facet, to ensure that the verticality and parallelism in 0.05mm, left margin of bilateral 0.6-6.8mm
3) Milling machine: First, the milling Machine Head correction, to ensure that in 0.02mm, the correction of pressing workpiece, first processing screw hole, thimble hole, threading hole, insert needle countersunk head Open, machine tsui or material nozzle hole, shunt cone hole chamfer to do water hole, milling r angle. 4 Fitter Processing: Tapping the teeth, typing code 5) CNC roughing 6 external heat Treatment Hrc48-52 7) fine grinding; The large mill is machined to a ratio of 0.04mm, ensuring parallelism and verticality within 0.02mm 8) CNC finishing 9 EDM 10) province mold, to ensure smooth finish, control the cavity size. 11) Processing gate, exhaust, zinc alloy in general case Gate open 0.3-0.5mm, vent 0.06-0.1mm, aluminum alloy gate open 0. $number. 2mm exhaust 0.1-0.2, plastic vent 0.01-0.02, as wide as possible, thin. slider machining process 1, first milling roughing six face 2 grinding six surface to size requirements 3 milling machine roughing hanging table 4 hanging table fine grinding to size requirements and with the die-mounted slide with 5 milling machine processing cant, ensure that the slope is consistent with the pressing block, leaving the residual fly Mode 6 drilling water and inclined guide hole, the Inclined Guide column hole is 1 mm larger than the guide pillar, and chamfer angle, the Oblique guide column hole inclination should be less than 2 degree of the slope of the slider. The inclined-guide cylinder can also be machined with the die holder after flying a good die, depending on the different conditions.
