Background

The mould is used for producing various moulds and tools of the needed products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods in industry. In short, a mold is a tool for molding an article, which is composed of various parts, and different molds are composed of different parts. The processing of the appearance of the article is realized mainly by changing the physical state of the formed material. The term "industrial master" refers to a tool that, under the action of an external force, makes a blank into a part of a specific shape and size. The method is widely used for blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting and the molding processing of compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The die has a specific contour or cavity shape, and the blank can be separated (blanked) according to the contour shape by using the contour shape with the cutting edge. The blank can obtain a corresponding three-dimensional shape by using the shape of the inner cavity. The mold generally comprises a movable mold and a fixed mold (or a male mold and a female mold), which can be separated and combined. And taking out the workpiece when the workpiece is separated, and injecting the blank into the die cavity for forming when the workpiece is closed. The die is a precise tool, has a complex shape, bears the expansion force of a blank, has higher requirements on structural strength, rigidity, surface hardness, surface roughness and machining precision, and is one of important marks of the mechanical manufacturing level.
