What is extrusion die?
Extrusion die belongs to a kind of molding die, but its discharging way is to realize the phenomenon by extruding this action. It is widely used in aluminum special-shaped structure and plastic parts. At the front end of the extruder, it is used to make pipes or profiles. The extrusion die can be described as a metaphor: pick up a hollow with the shape of a ruler on the bottom plate of the air cylinder, block the air outlet, pull out the piston, install yellow mud in the cylinder, insert the piston to suspend air to pump air, and then an extruded triangular iron can be obtained.
This pump is the extrusion die. In fact, the extrusion die is similar to this one, with high strength. It uses powder metallurgy cemented carbide as the bottom plate and uses hydraulic press to pump air. Mold: various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging molding, smelting, stamping, stretching and other methods to obtain the required products. Introduction: in short, the mold is a tool used to shape objects. This tool is made up of various parts. Different molds are made up of different parts. It is mainly through the change of the physical state of the formed material to achieve the processing of the object shape. Simple classification: according to the different materials, the mold can be divided into metal mold and non-metal mold. Metal mold is divided into: casting mold (non-ferrous metal die casting, steel casting), and forging mold; non-metallic mold is also divided into: plastic mold and inorganic non-metallic mold. According to the different materials of the mold itself, the mold can be divided into: sand mold, metal mold, vacuum mold, paraffin mold and so on.
Among them, with the rapid development of polymer plastics, plastic mold is closely related to people's life. Plastic mold can be generally divided into: injection molding mold, extrusion molding mold, gas assisted molding mold and so on. Large scale production of non sheet metal steel parts cold heading, die forging, metal mold and other sheet metal discharging hot rolling, cold rolling, hot rolling, cold rolling sheet metal processing drawing, expanding, bending, punching, blanking non-ferrous metal die casting, powder metallurgy plastic parts injection molding, blow molding (plastic bottles), extrusion (pipe fittings) mold other categories: alloy mold sheet metal mold plastic mold stamping mold casting Die making extrusion die.
