In today's society, precision molds have been widely used in people's life, work and other corners, so do you know how precision molds are classified? Today NJPE will answer this question for you. Precision molds can generally be classified according to the following main features: first, precision molds can be classified according to process properties: a. A die that separates materials along closed or open contour lines. Such as blanking die, punching die, cutting die, cutting die, cutting die, cutting die, etc. B. The bending die causes the blank or other blank to follow a straight line (Curved line) Produce bending deformation, thus obtaining a certain angle and shape of the workpiece mold. c. Drawing die is a die that makes a blank sheet into an open hollow part or further changes the shape and size of the hollow part. d. Forming die is a die that directly replicates and forms blank or semi-finished workpieces according to the shapes of convex and concave dies in the figure, while the material itself only produces local plastic deformation. Such as bulging die, necking die, flaring die, undulating forming die, flanging die, shaping die, etc. Second, precision molds can also be classified according to the degree of process combination: a. The single process die only completes one stamping process in one stroke of the press. B. The compound die has only one station. In one stroke of the press, two or more stamping processes are completed at the same station. c. Progressive Die (Also known as continuous mold) In the feeding direction of the blank, there are two or more stations. In one stroke of the press, two or more stamping processes are successively completed at different stations. Third, the precision mold can also be classified according to the processing method of the product: according to the different processing methods of the product, the mold can be divided into five categories: punching and shearing mold, bending mold, drawing mold, forming mold and compression mold. a. Punching die: it is completed by shearing. The common forms include cutting die, blanking die, punching die, trimming die, whole edge die, drawing die and punching die. B. Bending die: it is to bend the flat blank into an angular shape. Depending on the shape, precision and quantity of parts, there are many different forms of dies, such as ordinary bending die, Cam bending die, crimping die, arc bending die, bending punching die and twisting die, etc. c. Pumping mold: the pumping mold is to make a flat wool embryo into a bottom seamless container. d. Forming die: refers to changing the shape of the hair embryo by various local deformation methods, its forms include bulging forming die, winding edge forming die, necking forming die, hole Flange forming die and round edge forming die. e. Compression die: it uses strong pressure to make the metal wool embryo flow and deform to become the required shape. Its types include extrusion die, embossing die, embossing die and end pressing die.
