Molds, various molds and tools used in industrial production for injection molding, molding, extrusion, casting or forging, melting, baking, etc. To obtain the desired product. In short, a mold is a tool used to create a shaping article. The tool consists of different parts, and different molds consist of different parts. Generally it processes the shape of an article by changing the physical state of the formed material. Known as the "mother of industry" title.
It is emptied in a tool of a particular shape and size under the influence of external force. Widely used for removing, forging, molding, extrusion, pressing powder metallurgy, casting pressure, as well as pressing or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific shape or shape of the cavity, and the application of the shape of the contour with the blade allows the gap to be separated (drilled) in the form of a contour.
The application of the inner cavity shape allows a blind experiment to obtain the corresponding three-dimensional shape. The mold generally includes two parts, a movable mold and a fixed mold (or convex mold and concave mold) which can be split and combined. When parts are separated, parts are performed, and when the pieces are closed, gaps are injected into the cavity of the mold to form. Mold is a precision tool with a complex shape and carries an expansive dust force. It has high demands on structural strength, stiffness, surface hardness, surface roughness and precision of processing. The development level of mold production is one of the important signs of mechanical production.
