Mold production process flow

Drawing review - material preparation - processing - mold base processing - mold core processing - electrode processing - the first mock examination eye parts processing - inspection - assembly - flying mold - trial mold - production
A: Mold base processing: 1 dozen numbering, 2A/B board processing, 3 panel processing, 4 needle fixed board processing, 5 base plate processing
B: Mold core worker: 1 flash, 2 rough grinding, 3 milling machine processing, 4 bench worker processing, 5 CNC rough machining, 6 heat treatment, 7 fine warehouse, 8 CNC finish machining, 9 Electrical discharge machining, 10 die saving
C: Mold parts processing: 1. Slider processing, 2. Pressing block processing, 3. Diversion dimension gate bushing processing, 4. Insert processing mold base processing details. 1. Numbering should be unified, and the mold core should also be numbered, which should be consistent with the number on the mold base and in the same direction. Alignment during assembly can prevent errors.
2. A/B board processing (i.e. dynamic and fixed mold frame processing), a: A/B board processing should ensure that the parallelism and perpendicularity of the mold frame are 0.02mm, b: milling machine processing: screw holes, water holes, top needle holes, machine nozzle holes, chamfer c; Fitter
Processing: Tapping teeth, trimming edges.
3. Panel processing: Iron machine processing, boring machine nozzle hole or material nozzle hole processing
4. Processing of the top needle fixing plate: Milling machine processing: The top needle plate is connected to the B plate with a return needle, and the B plate is facing upwards and drilled with a top needle hole from top to bottom. The countersunk head of the top needle needs to turn the bottom of the top needle plate upside down and make corrections. First, use a drill bit for machining,
Finish machining in place with a milling cutter and chamfer.
5. Bottom plate processing: milling machine processing; Marking, correction, boring, chamfering,
(Note: For some molds that need to strengthen the top of the Lamian Noodles, strengthen the top pulling mechanism, such as adding a thread hole on the ejector plate) Details of mold core processing
1) Gongfei hexagonal: processed on a milling machine to ensure verticality and parallelism, with a grinding allowance of 1.2mm
2) Coarse grinding: Large water grinding processing, first grinding the large surface, using a screwdriver to clamp and grind the small surface, ensuring that the perpendicularity and parallelism are within
0.05mm, with allowance of 0.6-0.8mm on both sides
3) Milling machine processing: First, the washing machine head needs to be calibrated to ensure it is within 0.02mm. Then, the workpiece needs to be calibrated and compressed. First, screw holes, top needle holes, threading holes, embedded needle countersunk heads need to be roughened, machine or material nozzle holes need to be drilled. Then, the diversion cone hole needs to be chamfered before making a distant water hole and milling the R angle.
4) Fitter processing: tapping, typing codes
5) CNC rough machining
6) External heat treatment HRC48-52
7) Jingji; Grind with large water until it is 0.04mm negative than the mold frame, ensuring parallelism and verticality are within 0.02mm
8) CNC precision machining
9) Electrical discharge machining
10) Save mold, ensure smoothness, and control the size of the mold cavity.
11) Processing the gate, exhaust, and zinc alloy. Generally, the gate is open 0.3-0.5mm, and the exhaust is open 0.06-0.1mm. The aluminum alloy gate is open 0.5-1.2mm, and the exhaust is open 0.1-0.2, and the plastic joint exhaust is open 0.01-0.02. Try to be wider and thinner.
