If you are good at mechanics, you only need to supplement the forming principle of the mold, the corresponding knowledge of the properties of the processing materials, and the choice of the basic structure of the mold. It's better to look at the papers of students in your school's mold class and study the design steps and ideas with the papers, which is more important! It's almost there.

Generally speaking, molds can be divided into:

1. Hardware mold: processing all kinds of metals, including blanking mold, bending mold and drawing mold.

2. Plastic molds: plastic products can be divided into injection molds, die-casting molds, blow molds (plastic bottles) and so on.

3. Rubber mold: molding rubber products, including plate mold, strip mold, die-casting mold, rubber injection mold, blow mold, circlip mold, etc.

4. Forging die: forming forgings, mainly used for initial pier and initial forging in China, with low precision and simple structure (figuratively speaking, machinery replaces blacksmith).

5. Moulds: large parts of casting, sand casting, knife coins, copper coins, iron pot, aluminum pots, airplanes and ships, and small complex parts as early as thousands of years ago, with high or low accuracy.

6. Wax mold: it is mainly used to finalize the early model when some molds are formed.

7. Cardboard die: Stamping the carton packaging box, which belongs to the punching die.
