What Is The Mold

Moulds (m ú j ù) are various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. In short, a mold is a tool used to make molded articles. This tool is composed of various parts, and different molds are composed of different parts. It mainly processes the shape of the object by changing the physical state of the formed material. Known as the "mother of industry".
A tool used to make the blank into a workpiece with a specific shape and size under the action of external forces. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, as well as the molding and processing of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or inner cavity shape. Applying the contour shape with a blade can make the blank separate (blanking) according to the contour shape. Applying the inner cavity shape can make the blank obtain the corresponding three-dimensional shape. The mold generally includes two parts: moving mold and fixed mold (or male mold and female mold), which can be divided and combined. Take out the parts when separating, and inject the blank into the mold cavity when closing. Mold is a precision tool with complex shape and bears the expansion force of the blank. It has high requirements for structural strength, rigidity, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important indicators of the level of mechanical manufacturing.
