What are the advantages of vertical disc injection machines

Image
Vertical turntable injection molding machine is also called disk injection molding machine and multi-station injection molding machine. Its function is more than twice that of vertical injection molding machine. It can improve production efficiency through one machine with multiple molds (one set of upper mold, three sets of lower mold, More can be done) Vertical mold clamping, vertical injection, easy to pick up products; Qingdao injection molding machine's high-efficiency disc gear transmission is carried by plane self-lubricating wear-resistant plates, and the cooling water uses a central synchronous water transport device (water pipe can Simultaneous 360-degree rotation or 180-degree forward and reverse water supply device, complete cooling mold solution) Fast and accurate positioning of rotation, positioning cylinder positioning, high positioning accuracy, high safety performance, final positioning is not close to the mold, to protect the normal use of the mold. This model...

About the control problem of the injection molding machine

Image
Modern plastic injection molding machine is a typical system integrating machine, electricity and liquid. Because of its characteristics of complex molding, less processing, and many types of plastics processed, it has developed extremely rapidly since its inception. More than 80% of the world's engineering plastic products are processed by injection molding machines. Conventional injection molding machines generally use simple open-loop control, which is controlled according to preset values. In the manufacturing process of the device, parameter values ​​such as clamping force, cycle time, temperature, etc. are preset in advance, and are maintained by the machine during the production process. For example, the mold temperature can be maintained by controlling the temperature of the heating fluid, which can be maintained by controlling the power of the external heating device. This control method has a simple structure, but the anti-interference ability is poor, and the contro...
