Quick Mold Change System

It is an era for making high frequency mol d change with multiple patterns and smalI quantity. In order to save t ime for the mold change and ensure the safety of the operation, it is just in time to apply quick Mold Change System. Safety function of system

Each hydraulic circuit has the function of checking and avoiding oil leakage.
Each hydraulic circuit has the function of inspecting pressure and can be interlocked with the machine.
It adopts the intersecting direction to clamp the mold.
There are several functions to avoid operation errors.

Control Operation Panel

Machine will be stopped automatically in case of operational errors.
Mold change for single side is functioned with two-way operation only for avoiding operational errors.
It is equipped with key switch to prevent operational errors.
During mold changing, it will check the following steps automatically: Injection unit backward, Ejector backward, Manual mode, and Mold close as signal requirement for unclamping. It can avoid operation errors and possible damages.
When changing molds or malfunction, it will send signals to stop machine opening/closing the mold.
