Process Flow Of Injection Mold

Process flow of injection mold

Template processing details

1) The number should be unified, and the core should be numbered. It should be consistent with the number on the mold base, and the direction should be the same. It is not easy to make mistakes when assembling.

2) A/B board processing (that is, mobile mold base processing).

A, A/B board processing should ensure that the parallelism and perpendicularity of the mold base is 0.02mm;

b. Milling machine processing: screw hole, water hole, thimble hole, machine hole, chamfer

C: fitter: tapping and trimming.

3) Panel processing: Milling machine processing machine nozzle hole or processing nozzle hole.

4) Processing of the thimble fixing plate: milling machine processing: the thimble plate is connected with the B plate and the rear needle, the B plate is upward, and the thimble hole is drilled from top to bottom. The countersunk head of the thimble needs to flip up the ejector plate. After correction, rough machining with a drill bit, and then a milling cutter to process it in place and chamfer it.

5) Floor processing: milling machine processing: marking, correction, boring, chamfering. (Note: Some molds need to pull the top strength forcefully to strengthen the top mechanism, such as adding screw holes on the thimble plate)

Inhibitor

To become a comprehensive mold manufacturing company, you need to purchase a lot of machinery, equipment, instruments, and introduce professional and technical personnel, which requires a lot of capital. The demand for capital scale requires other companies to cross a higher threshold when entering this industry. At the same time, the service objects of precision equipment mold companies are mainly large companies, and the scale of business of large companies is often very large. This requires that mold companies, as an important part of their supply chain, must have a large production scale, only when the production scale can be achieved. Effectively reduce procurement costs and production costs.

Core processing details

1) Coarse and flying six sides: Machining on a milling machine to ensure perpendicularity and parallelism, leaving a grinding allowance of 1.2 mm.

2) Coarse grinding: large water mill processing, first grind the large surface, clamp the small surface in batches, ensure that the perpendicularity and parallelism are within 0.05mm, leaving a margin, and both sides are 0.6-0.8mm.

3) Milling machine processing: firstly calibrate the milling machine head to ensure that it is within 0.02mm, calibrate the pressed workpiece, first process the screw hole, thimble hole, and threaded hole, insert the needle to open the thick, machine nozzle or material nozzle hole, and the flow cone is Chamfer. Red, and then form water holes, grinding out the R angle.

4) Machining: tapping and coding.

5) CNC rough machining: reserve the remaining amount.

6) External heating place HRC48-52.

7) Fine grinding; large-scale water milling is performed on the bottom frame of 0.04mm to ensure that the parallelism and perpendicularity are within 0.02mm.

8) CNC machining.
