Plastic mold processing, electronic products about the classification of injection mold what?
The shapes and classification methods of injection mould for electronic products are various. According to the equipment method of the injection molding machine, it can be divided into mobile (vertical injection machine only) and fixed injection mold. According to the type of syringe used, can be divided into horizontal or vertical syringe syringe syringe mold and angle syringe syringe syringe mold.
In addition, according to the different mold, the mold cavity can be divided into one-way cavity and multi-cavity injection mold, according to the size of molding products can be divided into large, medium and small injection mold.
According to the overall structure of the injection mold, it can be divided into a single parting surface injection mold and double parting surface injection mold. Single parting surface injection mold, also known as two (double) plate injection mold, is a commonly used standard structure.
The die has simple structure and reliable operation, and is especially suitable for the production of large box and shell products. A double parting die for electronics means that the casting system and the product are removed from the different parting surfaces. It adds a movable center plate, as opposed to a single parting die, the die consists of a fixed runner plate and a moving template with parts.
Injection mold is widely used in the production of plastic products, can form a number of complex structure, size precision, internal quality of good plastic parts. However, the design and manufacture process of injection mold is complex and influenced by many factors. The gating system is an important part of injection mold structure design, which directly affects the rheological behavior and filling effect of polymer melt in the mold channel, and finally affects the molding quality of plastic parts. Many defects in the molding process of plastic parts, such as jet flow, warping deformation, weld marks and under-injection, are closely related to the design of gating system.
The application of injection mold not only plays an important role in the manufacture of electronic products, but also is widely used in other industries. By understanding the classification and characteristics of injection mold, we can better choose the mold for specific production needs, improve production efficiency, reduce production costs and promote industrial development.
