molds are divided into three categories according to the different materials they are molded. Hardware mold, plastic mold and its special mold.
Hardware dies are divided into: stamping dies (such as blanking dies, bending dies, drawing dies, hole-turning dies, hole-shrinking dies, undulating dies, bulging dies, shaping dies, etc.), forging dies (such as forging dies, upsetting dies, etc.), extrusion dies, die-casting dies, forging dies, etc. Non-metallic molds are divided into plastic molds and inorganic non-metallic molds.
According to the different materials of molds, molds can be divided into sand molds, metal molds, vacuum molds, paraffin molds 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 mold, extrusion molding mold, gas-assisted molding mold and so on.
meaning of mold: various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting and stamping. In short, a mold is a tool used to make molded articles. This 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 through the change of the physical state of the molded material. Known as the "mother of industry".
Extended data:
The template size should be larger than the work area, and the standard template size should be selected. The position of the template locking screw is related to the mold type and template size. Among them, locking screws are most commonly used in the four corners of single engineering molds, and the most standard working areas can be widely used. Long molds and continuous molds are most often arranged at four corners and middle positions with locking screws.
the selection of the thickness of the template is absolutely related to the structure of the mold, the types of stamping, the processing power of stamping and the precision of stamping. It is difficult to determine the thickness of the die according to theoretical calculation, which is generally obtained by experience. The types of die thickness used in design should be as few as possible, and the die height and clamping height should be standardized to facilitate procurement and inventory management.
the cutting edge of the die must be ground after long-term use, and the ground cutting edge surface must be demagnetized without magnetism, otherwise it is easy to block the material. Mold users should make detailed records and statistics on their use, care (lubrication, cleaning and rust prevention) and damage.
During the use of the die, the punch is prone to break, bend and gnaw, and the punch sleeve is generally gnawed. The damage of punch and punch sleeve is generally replaced with parts of the same specification. The parameters of punch mainly include working part size, installation part size, length size and so on.
