First of all, you should have a macro concept of mechanical design, and then study the knowledge of mold design seriously. Hehe, I am learning. I bought a plastic mold manual and looked at it. I used to study mechanical design, but now I am a vocational school teacher. Because the equipment purchased by the school has the basic ability of mold processing, I want to try to make molds. This thing should not be hard to think about. If a college student is willing to work on it, he should be able to learn it. Prerequisites: Mechanical drawing is solid, and you can't design if you can't read the drawing.

However, judging from what you said, it seems that your factory makes plastic parts, so it is only using molds, not producing molds. Have you studied the operation of injection molding machine? I have seen that thing, but I haven't studied it carefully. I think it is nothing more than setting the clamping pressure, injection pressure, cooling rate, holding time and so on. When the mold leaves the factory, someone else's mold factory will try it out and tell the customer the parameters. If you learn to try the mold, it is mainly experience.

The general process of mold production is to determine the parting mode and the overall mold design direction according to the product requirements or drawings, and then use CAD/CAM software to model the mold parts, and generate the machining program for the parts that need NC machining on the machine tool. Some details can't be processed by cutting, so we have to design electrodes according to the shape of the corresponding parts on the mold, use CNC milling machine or machining center as electrodes, and then EDM the cut mold. These are all done. If necessary, take them to the workers for polishing. Mould bases and the like are all standard parts. What should I do? These are all done. Let the fitter assemble them. Better install them. If it is not installed, continue to repair. Finally, try the mold, and deliver the goods if there is no problem with the mold test. To put it simply: first have a big design direction, then try to meet the requirements one by one, and then assemble and test. After the trial mold is completed, fine polishing can usually be carried out.

Don't worry if you just graduated. What you want to learn depends on whether you are serious or not. When you enter the factory, I suggest you take a small notebook and record any technical problems you encounter. For example: what product, how did the master make it? What problems have you encountered and how did the master deal with them? Even if you are the operator of the machining center, you will gain a lot as long as you carefully record: a certain material, what kind of tools are used, how many blades are used, how the front angle and back angle are, how the cutting speed is, how many knives are eaten, how the effect is, how the tool life is, and so on. No one will be afraid to teach you as long as you are willing to study hard. People who have a heart for one year have learned what lazy people can't learn in 10 years. Careful observation and thinking, coupled with self-study of theoretical knowledge, will be rewarded sooner or later.
