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 processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. The element has the name 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 blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting and the forming processing of 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 (blanked) 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 blank is closed, the blank is injected into the die cavity for forming. 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 processing precision, and the development level of die production is one of important marks of the mechanical manufacturing level.
In the production process of the injection mold, because the heated liquid plastic is in a specific production environment with high temperature, high pressure and high speed, the liquid plastic and the mold generate friction to enable the outer surface of the plastic to be partially degraded, most of the degraded plastic is converted into gas to be discharged out of the mold, a small amount of oily, corrosive and heavy metal mineral components can be attached to the surface of the mold, and oil-containing mineral scale and rust marks are generated on the surface of the mold in a long-term accumulation manner.
