No matter how complex the mold is, in general, the process flow of mold manufacturing is basically: drawing review → material preparation → processing → mold base processing → mold core processing → electrode processing → mold parts processing → inspection → assembly → flying mold → trial mold → Production.
1. Mold base processing Numbering A/B board processing Panel processing Thimble fixing plate processing Bottom plate processing
2. Mold core processing Flash Coarse grinding Milling machine processing Fitter processing CNC rough machining Heat treatment Fine grinding CNC finishing EDM Wire cutting (slow wire walking) Provincial mode
3. Mold parts processing Slider processing Pressing block processing Split taper sprue bushing processing Inlay processing Mould base processing details
1) The numbering must be unified, and the mold core must also be numbered. It should 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 board processing (ie, moving and fixed mold frame processing). A. A/B board processing should ensure that the parallelism and perpendicularity of the mold frame is 0.02mm; B. Milling machine processing: screw hole, water hole, thimble hole, nozzle hole, chamfer C: fitter processing: tapping, trimming burrs.
3) Panel processing: milling machine processing boring machine nozzle hole or processing material nozzle hole.
4) Processing of thimble fixing plate: Milling machine processing: the thimble plate and the B plate are connected with a backtack, the B plate is facing up, and the thimble hole is drilled from top to bottom. The countersunk head of the thimble needs to be turned up and the bottom of the thimble plate is reversed. The drill is roughed, and then finished with a milling cutter to chamfer.
5) Bottom plate processing: milling machine processing: marking, correction, boring, chamfering. (Note: For some molds that require strong tensile force, a strong tensile force mechanism must be added, such as drilling screw holes on the thimble plate)
