Mold (Mu Ju), industrial production for injection molding, blow molding, extrusion, die casting or forging, forming, smelting, stamping and other methods to get the required products of all kinds of molds and tools. In short, the mold is used to make the tools of molding items, this tool is composed of a variety of parts, different molds by different parts
It is mainly through the physical state of the material to achieve the shape of the processing of goods known as the "mother of industry" title.
Tools that make billets into parts of specific shape and size under the action of external force are widely used in punching die forging, cold heading extrusion, powder metallurgy parts, pressure casting, and engineering plastics, rubber, ceramics and other products, pressure molding or injection molding
Mold with a specific or inner cavity shape, the outline of the application has the edge contour shape can be made according to the outline shape occur separation (blanking) application within the cavity shape can make the blank to get the corresponding three-dimensional shape Mould generally includes moving die and die (or punch and die) two parts, can be divided into two separated can close out parts, folded shape billet injection mold cavity
Mold is a precision tool, the shape is complex, bear billet bulging force, the structural strength stiffness, surface hardness, surface roughness and processing precision have higher requirements, the development level of mold production is one of the important marks of the level of machinery manufacturing
The plastic mould is a coordinated change of the composite mould for emboplastic injection blow and low foaming molding, which can be processed in different shapes of different shapes.
Head mould is the main function of channeling extruder extrusion of plastic materials to mouth parts Will leave extruder screw groove of irregular flow instability of rubber, lead to excessive to stabilize the flow of rubber, made out of the mouth of a stable cross section shape of strip of rubber extruder head mould has two kinds, respectively is cylindrical mold and
