1. Mold opening, pressure, speed, position, and setting confirmation. The starting voltage of the opening and closing directional valve is normal, and there is no blockage in the valve core.
2. If the injection pressure is too high or the mold produces a vacuum phenomenon, causing the inability to open the mold, adjust the opening speed and pressure to the maximum value; Make sure to check the mold pressure plate and re lock it. Lock the mold first and then open it. After opening the mold, modify the exhaust of the mold and adjust the pressure and speed back to the standard values.
After the molten plastic is injected into the mold cavity and cooled, the mold is opened and the product is removed. The mold making process is also divided into three stages. The first stage is to slowly open the mold to prevent the workpiece from tearing inside the mold cavity. The second stage is to quickly open the mold to shorten the mold opening time. The third stage is to slowly open the mold to reduce the impact and vibration caused by mold inertia.
