The importance of the mould:
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. Mold with specific outline or inner cavity shape, has the edge contour shape can be made according to the outline shape separation, namely for blanking; Inner cavity shape can make to get the corresponding three-dimensional shape, mold generally divided into two parts: moving mould and die, or punch and die, which can be divided into us. Separated into blank or remove parts, closed when the separated parts and block or take shape. In blanking, stamping forming, die forging, cold heading, pressing and molding process, separation or by mold forming the external forces applied on the blank; In the process of extrusion, die-casting and plastic injection, external force by the pressure, piston, punch, such as imposed on the blank, the mold is under billet bulging force. Mould besides itself, also need to die, die frame, guide and parts of the device, etc., these parts are generally made universal, suitable for a range of different mould. The application of the mold is very extensive, mass production of mechanical and electronic products, such as cars, bicycles, sewing machines, cameras, motors, electrical appliances, instruments, etc, as well as the manufacture of household utensils are used a lot of mold. Mold is basically a single production, its shape is complex, the structure strength, stiffness, surface hardness, surface roughness and machining accuracy have very high requirements, so the mold production needs to have a high technical level. Mould timely supply and its quality, directly affects the quality of the product, cost, and new product development.
