Type and classification of molds
Mold, industrial production of various molds and tools for injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, etc. to obtain the desired product. In short, a mold is a tool for making a shaped article, and the tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article by changing the physical state of the formed material. Known as the "mother of industry" title.
The blank is made into a tool of a specific shape and size under the action of an external force. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, as well as compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or cavity shape, and the application of the contour shape with the cutting edge allows the blank to be separated (punched) in the shape of the contour. Applying the inner cavity shape allows the blank to obtain a corresponding three-dimensional shape. The mold generally includes two parts, a movable mold and a fixed mold (or a convex mold and a female mold), which can be divided and combined. When the parts are separated, the parts are taken out, and when they are closed, the blanks are injected into the mold cavity to form. The mold is a precision tool with complex shape and bearing the expansion force of the blank. It has high requirements on structural strength, stiffness, surface hardness, surface roughness and processing accuracy. The development level of mold production is one of the important signs of mechanical manufacturing level.
Types
There are many types of molds
According to the processing object and processing technology can be divided into:
1 processing metal mold.
2 Processing non-metal and powder metallurgy molds. Including plastic molds (such as two-color molds, compression molds and extrusion molds, etc.), rubber molds and powder metallurgy molds. According to the structural characteristics, the mold can be further divided into a flat punching die and a cavity die having a space. The mold is generally single piece and produced in small batches.
classification
Depending on the material being formed
Hardware molds, plastic molds, and their special molds.
Hardware molds are divided into: including stamping dies (such as punching dies, bending dies, deep drawing dies, boring die, shrink hole dies, undulating dies, bulging dies, shaping dies, etc.), forging dies (such as die forging dies,upsetting die, etc.), extrusion die, extrusion die, die-casting die, forging die, etc.;
Non-metal molds are divided into: plastic molds, inorganic non-metal molds, sand molds, vacuum molds and paraffin molds.
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 the like.
