What are the applications and advantages of the rapid mold change system?

The rapid mold change system is a process improvement method aimed at reducing mold change time, production start-up time, or adjustment time, with the aim of significantly reducing the time required for machine installation and mold change settings. This method has been applied in the field of injection molding machines for at least 30 years and is mainly used on large tonnage injection molding machines. The advantages of the rapid mold change system include complete openness around the mold, but the weakness is that a unified clamping mechanism needs to be installed on the back plate of the mold, which is characterized by clamping at the center of the back of the mold. ‌

The application background of the rapid mold changing system reflects the intensification of market competition and the acceleration of plastic product updates, especially in the automotive industry, which requires parallel, complete, and timely products for different vehicle models. Therefore, the interval between mold replacements is becoming shorter and the frequency is increasing, resulting in increased downtime of injection molding machines and seriously affecting production efficiency and machine utilization. In order to solve this problem, industrialized countries in Europe and America have adopted rapid mold changing systems and achieved significant results.

The implementation methods of rapid mold changing systems include mechanical rotary pull, hydraulic pressure plate, and magnetic suction cup. For example, the electronic control permanent magnet rapid mold changing system utilizes a new magnetic force replacement mold system with electric pulse switch magnetic force, which controls and converts the distribution of internal magnetic circuits through the electronic control system to achieve mold clamping and replacement.

The rapid mold replacement system is not only suitable for traditional injection molding machines, punching machines, and mold closing machines, but also can achieve rapid mold replacement through simple demagnetization actions, greatly improving production efficiency and machine utilization.
