Performance Analysis of injection molding machine
Also known as injection molding or injection molding machine maker. It is the use of thermoplastic or thermosetting plastic mold material into various shapes of plastic products the main molding equipment. Injection molding machine according to the arrangement of the injection device and the clamping device can be divided into vertical, horizontal, and vertical and horizontal composite.
Injection molding machine is used in the plastics processing industry the largest processing machinery, only a large number of products available for direct production of injection molding machines, but also the composition of the injection stretch blow molding process of key equipment. China has become the world's superpower presses pieces of production, promote the development of Chinese injection molding machine equipment manufacturing reason is: First, the world's leading enterprises and joint ventures and technical cooperation; Second, Chinese enterprises have gradually adapted to the mechanical parts of the international Bian purchase mode, master Bian shopping channels. Meanwhile, China's injection molding machines, also showing a strong regional characteristics, Ningbo and Dongguan, Guangdong, Zhejiang and other places, and the world has become an important production base of injection molding machines.
Injection molding machine usually consists of the injection system, clamping system, hydraulic drive system, electrical control system, lubrication system, heating and cooling systems, security monitoring systems and other components.
Injection System
Role of the injection system: Injection system is one of the most important components of the injection molding machine, generally have a plunger, screw-type, screw pre-plastic syringe plunger three main forms. Currently the most widely used is the screw. Its role is in a cycle of injection molding machines, after energy within the specified time will be a certain amount of heat plasticized plastic under certain pressure and speed, by the screw will melt the plastic into the mold cavity. After the injection, the injection into the mold cavity melt holding stereotypes.
Composition of the injection system: injection system by the plasticizing device and the power transmitting device.
Plasticizing screw injection molding machine mainly consists of feeding device, a cylinder, a screw, a plastic component nozzle parts. Power transmission means including injection cylinder, injection cylinder and a screw driver seat moving means (melting plastic motor).
