Kunshan mold processing (M J), all kinds of moulds tools needed for industrial production are obtained by injection molding, blow molding, extrusion, die casting forging, smelting, stamping so on. In short, mold is used to make molding tools. This tool is made up of various parts, different molds are made up of different parts. It mainly realizes the processing of the shape of the articles by changing the physical state of the formed material. Known as the "mother of industry".
Under the action of external force, the billet becomes a tool with specific shape size. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, as well as molding injection molding of engineering plastics, rubber, ceramics other products. The mold has a specific contour inner cavity shape, the shape of the cutting edge can be used to separate the blank the contour line (blanking). The shape of the inner cavity can be used to obtain the corresponding three-dimensional shape of the blank. The mold generally consists of two parts, the movable die the fixed die ( punch concave die), the two parts can be divided into two parts. When separate parts are removed, the blank is injected into the mold cavity to form. Mold is a sophisticated tool, with complex shape, bearing the expansion force of billet, has high requirements for structural strength, rigidity, surface hardness, surface roughness machining accuracy. The development level of mold production is one of the important signs of machinery manufacturing level.
According to the processing object processing technology, it can be divided into:
(1) processing metal mold.
Second, processing non-metal powder metallurgy mold. It includes plastic mould (such as two color mould, pressing mould extrusion die, etc.), rubber mould powder metallurgy mould. According to the structural characteristics, dies can be divided into flat punching dies cavity mold with space. The mold is usually single small batch production.
