What if the injection molding machine can't open the mold?

The mold opening force of injection molding machine is far less than the mold locking force, so the ultimate reason for mold opening failure is that the mold opening resistance is greater than the mold opening force. In actual operation, the mold can't be opened in the following situations: \x0d\ 1. The mechanical origin of mold locking of injection molding machine is not properly adjusted at the factory. Too advanced, causing tissue to get stuck. If you can't open the mold often, you should doubt this and find the manufacturer to set it up. \x0d\ Second: The mechanism is still stuck. This is not the first case for the old machine, so we should doubt this situation. Generally, the clamping force is adjusted too much, such as 1700 kg, and other habits are not good, such as not opening the mold for a long time and the system degenerates. This problem comes down to the adjustment habits and parameters of technicians. The solution is very troublesome, and it is necessary to remove or loosen the fixing nuts on the cross bar. \x0d\ Thirdly, the oil seal of the mold locking cylinder is damaged and leaks oil, which leads to the failure of the actual mold opening pressure. For this reason, it is useless to look at the pressure gauge, and the cylinder should be disassembled for inspection. \x0d\ Fourth: the valve core of the mold opening solenoid valve moves badly, or is stuck, and the valve core is not in place. The solution is to remove the solenoid valve for inspection. \x0d\ Fifth: See whether the parameter design is appropriate and the pressure is enough. \x0d\ Sixth: There may be a problem with the lubrication of the mode-locking system. Inspection and maintenance.
