What is the purpose of the mould
If you haven't seen it, one or two words are not clear, and the man above has given the standard answer. If you still don't understand, you would think so, such as shoes, if you want to shoe shape, inside a shoe last to the shoe, and then the shoe last is mould. For example, the brick that builds a house, all use a square box to do, this four box also is the mold. The clay POTS used in the neolithic people were also made of molds. For example, buckets, lunch boxes, water cups, home appliances, cars, etc. All you see and use are made of molds. It can be said that if there were no moulds, there would be no civilization! Modern westerners to die is the origin of the rules for German (ancient former German emperor ruled by the Swedish region) invented by the shoemaker, this is in order to prove that westerners are smarter than the east.
The mould is the most widely used in the industrial production, the die industry is the basic industry of the national economy. Widely used in modern industrial production, product parts forming, extrusion forming, stamping, die-casting, forging forming, plastic injection, or other forming method, and the forming mould, make the billet forming parts to meet the requirements of the product. The development of many industries, such as electromechanical, automobile, light industrial, electrical appliance, communication, weapons, etc., depends on the development of the technology of the mould industry.
Mould is in blanking, stamping forming, forging, cold heading, extrusion, powder metallurgy parts suppression, pressure casting, as well as engineering plastics, rubber, ceramics and other products of compression or injection forming, the action of external force to make blank into a specific shape and size of the stamping tools. The mold has certain contour or inner cavity shape, the shape of the blade can be separated by the shape of the outline, which is the blanking of the die. The inner cavity shape enables the billet to obtain the corresponding solid shape. (add, foreign divided into two categories: the DIE cut of the MOLD and DIE. MOLD means "MOLD, MOLD cavity", refers to such as MOLD, casting MOLD, DIE mean "metal MOLD, stamping DIE, DIE, forging DIE. Respectively is simple: one is the material after heating melting into the cavity, one is to use external force pressed materials into the required shape.)
