What is a mold, and what is a mold
Under external force, the material is made into a special shape and dimension. Widely used in cutting, forging, cold heading, extrusion, powder metallurgy parts suppression, pressure casting, as well as engineering plastics, rubber, ceramics and other products of the molding or injection forming. The mold has a certain contour or inner cavity shape, and the shape of the blade can be separated by the shape of the outline. The inner cavity shape can be used to obtain the corresponding solid shape. The mould usually includes two parts: the moving model and the mold (or the punch and the concave), which can be divided into two parts. When apart, take out the pieces and put them into the mold cavity forming. Mold is a precision tool, complex shape, bear the expansion force of billet, the structural strength, stiffness, surface hardness, surface roughness and machining accuracy have higher request, the development level of mold production is one of the important symbol of the levels of mechanical manufacturing. There are many kinds of molds, according to the processing object and the processing technique can be divided into: the mould of processing the metal. The mould of non-metal and powder metallurgy. Including plastic mold (such as injection mould, die mold and extrusion die), rubber mould and powder metallurgy mold etc. According to the structural characteristics, the mould can be divided into flat blanking modes and spatial modes. The mould is usually single, small batch production.
The television, all the electrical appliances before production should have a model like his model can be made by machine, which is the die! -
A mold is a tool, a set of molds is a set of tools. A set of upper and lower boxes that used to be used to make Popsicle can be called a mold.
Mould industry in China is only about 50 years, mould simple said is the mother of industry, economic benefit, is the amplifier from daily necessities to the aerospace, transportation, electronics, transportation and other industries of national economy is inseparable from the mould, in short, we have encountered heard 90% of all kinds of items are mold production and processing. The mould includes various kinds, such as plastic mould, stamping die, hardware mould, powder metallurgy, casting and so on. The concept of a mold is relatively general, but there must be a few aspects, 1, 2 independent process molding function, complete the process of molding process 3, finished parts removed. This is an essential aspect.
