What are the safety protections of the Quick Mold Change System （Ⅰ）
When we talking about the Quick Mold Change System, everyone thinks of the advantages of time-saving, labor-saving, convenient..., etc. About the safety protection, we think that few people may notice this part. Now, let us instruction on the safety protections of the Quick Mold Change System.
First, let’s instruction on the hydraulic of safety protections:
-
● Each hydraulic circuit has the function of check and avoiding oil leaking：
When there is no air pressure or electricity and no oil leakage in the outer tubes. The system pressure can be keeps more than one week (Non-leak valve made by SANDSUN that can be hold the pressure more than 3 years)
-
● This system can add pressure automatically when the pressure reduction:
The hydraulic pump is driven by air. Once the hydraulic pressure reaches the pressure setting, it stops pumping which is energy saving. Meanwhile, if the working pressure reduces, the pump would supply pressure automatically to keep working pressure continuously.
-
● Each hydraulic circuit has the function of inspection pressure and can be interlocked with the machine:
Each hydraulic pressure has a pressure switch. When the pressure is lower than the setting of the pressure switch. The signal will be sent to the machine to stop the machine to prevent accidental occurrence.
-
● It adopts the intersecting direction to clamp the mold:
One of the circuit is abnormal of the hydraulic pressure, the diagonal die clamp will still clamped the mold, and then match the pressure switch, when the pressure is lower than the pressure switch setting. The signal will be sent to the machine to stop working.
-
● When the power is cut off, the die clamp will automatic clamping the mold:
This system adopts the design of automatic clamping the mold when the power is cut off. If the power cut off suddenly, the die clamp will is still clamping the mold and it does clamped the mold.
