Background

The mould is used for obtaining various moulds and tools of required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The method realizes the processing of the shape of an article mainly through the change of the physical state of a formed material. Plain has the designation of "industrial mother". The blank is formed into a tool with a specific shape and size under the action of external force. The method is widely applied to the forming processing of blanking, die forging, cold heading, extrusion, piece pressing, pressure casting, and compression molding or injection molding of products such as engineering plastics, rubber, ceramics and the like. The die has a specific contour or cavity shape, and the blank can be separated (punched) according to the contour shape by applying 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 or combined. When the two parts are separated, the part is taken out, and when the two parts are folded, the blank is injected into the cavity of the mold for forming.
