Chinese Plastic Injection Mold Maker Process
Customers around the world are now here we purchase mold behalf mold factory in China to take everyone to understand some of the plastic mold manufacturing process simple, so that we can understand more clearly understand the structure of the plastic mold. Mold making process is as follows: Approval – preparation – processing – moldbase processing – core processing – electrode machining – mold parts processing – Inspection – assembly – fly mode – test mode – Production
A: processing of moldbase: 1 playing No. 2 A / B plate processing, 3 panel processing, thimble fixed plate processing, 5 backplane processing
: Core processing: 1 burrs, rough grinding, 3 milling machine processing, 4 benching, 5CNC roughing, 6 heat treatment, the 7 Jingmo, 8 CNC finishing, EDM, 10 provincial-mode
C: Mold parts processing: 1 sliders processing, 2 clamping block processing, 3 shunt cone gate sets processing, the 4 inserts processing mold base processing details 1 hit No. unified the core but also marked with numbers, should die shelves Number consistent and in the same direction, and the assembly alignment can be less error-prone. 2, A / B board processing (ie, moving and stationary mold frame processing): A / B board processing should guarantee the the mold frame parallelism and verticality 0.02mm b: milling machine: screw holes, carrying water hole, top pinhole, machine Tsui holes, chamfers c: fitter Processing: tapping, repair the burr. 3, panel processing: milling machine boring machine nozzle hole or processing material mouth hole. 4, thimble fixed plate processing: milling machine: ejector plate and B plate with link back to the needle, the B board oriented, top-down drill top pinhole, thimble countersunk head requires ejector plate, in turn, the bottom upward correction, first with drill roughing Use cutters finishing place, chamfer. 5, bottom plate processing: milling machine: crossed correction, boring, chamfering. (Note: some die to be strong to pull strong top plus stronger pull strong top institutions, such as the in thimble board plus drilling screw holes) core processing details 1) roughing fly six sides: machining on a milling machine, to ensure squareness and parallelism, stay grinding margin 1.2mm 2) kibble: water mill processing, grinding Omo clamping grinding facet batch Secretary to ensure squareness and parallelism left margin bilateral 0.05mm, 0.6-0.8mm 3) milling machine: first milling head correction, calibration clamping the workpiece before machining the screw holes within 0.02mm, top pinhole threading hole rough opening the insert needle Shen head, machine the Aguilar or material Tsui hole shunt the the chamfer cone do transport water hole, milling R angle. 4) fitter processing: Tapping, typing code 5) CNC Roughing 6) Hair the outside heat treatment HRC 48-52 7) the fine grinding; big Shuimo processing to specific modulus box minus 0.04 mm, ensure parallelism and verticality 0.02 mm within 8) CNC finishing 9) EDM 10) Provincial mode, to ensure finish control cavity size. 11) processing into the gate, exhaust, zinc alloys, under normal circumstances gate opening 0.3-0.5mm, an exhaust opening 0.06-0.1mm, 0.5-1.2mm aluminum gate opening the exhaust opening 0.1-0.2, plastic Exhaust open 0.01-0.02 as wide as possible, a little thin.
