1. Extrusion mold knowledge
1: Definition
The extrusion mold is a kind of forming mold, but its discharging method is achieved through the action of extrusion. It is widely used in aluminum special-shaped structures and is also used in plastic parts. At the front end of the extruder, it is used to make pipes or profiles. In short, the mold is a tool used to mold an item, which is composed of various parts, and different molds are composed of different parts, which mainly realizes the processing of the shape of the item through the change of the physical state of the molded material.
According to the different materials formed, molds can be divided into metal molds and non-metal molds.
2: Classification
Metal molds are further divided into:
Casting molds (non-ferrous metal die-casting, steel casting), and forging molds, etc.;
Non-metallic molds are also divided into: plastic molds and inorganic non-metallic molds.
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 molds are closely related to people's lives.
Plastic molds can generally be divided into: injection molding molds, extrusion molding molds, gas-assisted molding molds and so on.
2. What are the types of molds?
1. Cold extrusion die
Cold extrusion die refers to the mold in which the metal blank is put into the cold state, and the metal is forced to be extruded from the mold cavity under the action of strong pressure and a certain speed in the cavity, so as to obtain the required shape, size and extrusion with certain mechanical properties.
2. Extrusion mold
Extrusion die is a type of molding mold, but the discharge method is achieved through the action of extrusion. It is widely used in aluminum special-shaped structures and is also used in plastic parts. At the front end of the extruder, it is used to make pipes or profiles.
3. Die-casting mold
Die casting mold is a tool for casting metal parts, a tool to complete the die casting process on a special die casting die forging machine.
4. Plastic mold
Plastic mold is an abbreviation for a combination mold used for compression, extrusion, injection, blow molding and low foaming molding. The coordinated change of the mold convex, concave die and auxiliary molding system can process a series of plastic parts of different shapes and sizes.
