Injection molding technology is widely used. I hope this article can give some inspiration to friends who want to understand this knowledge.——-Vito.
First, the principle of hollow blow molding machine
Plastic blow molding machine is a liquid spray out, after using the machine to blow out of the wind, blowing plastic body attached to a certain shape of the cavity, plastic parison strike put in split cavity, mold closing immediately after ventilation with compressed air within the parison, make plastic parison swell and clingy wall in the mold, the cooling mold release, the products have all kinds of hollow. It is often used for blowing PE and other hollow products of various materials, such as barrels, drums, beer preservation containers, tool boxes, lampshades, etc.
Two, the structure of the hollow blow molding machine
The hollow blow molding machine is mainly composed of extruder, head, hydraulic system, die closing system, electrical control system, inflation system, automatic clamping and other parts. The basic structure is mainly composed of the power part and the heating part. The power part is mainly composed of frequency converter and power output motor, which is the main working part of energy transmission and wind power output. The heating part is composed of an electromagnetic heater and a bracket part, which can be used to heat the plastic that needs to be blown into shape, so as to maintain its long-term softening characteristics.
