What is the top and bottom die in the mould?
Hello, before you answer your question, I want to tell you that you are just as misguided as any other student. Moulds itself no, under the touch, it's like: two tiles together, we can't say targeted on brick, brick, if there is a mould of lower die on concept, studied physics knows, it is need a reference or a reference point. Two cavity, the most common type of mold is the so-called two mould, is there are two main cavity, you can control open mould, also can open mould, therefore, only under the condition of upper and lower mould work, just have upper die, the meaning of the lower die.
Generally speaking, the upper and lower mould is in punching machine, casting machine, hydraulic press is the most common, and in this case, the upper die also called dynamic model, the model is called a static mode, this is because, when opening the die was mechanical drive dynamic model, complete open mold, so, in the upper die and lower die.
The mold is the production tool that must produce something special! It's usually a part of a machine, or a punching machine. There are many other food products such as moon cakes which will also be used in the mould! So to make a variety of shapes, you need two or two molds to complete the shape of the thing.
