Unlocking the mold is the most likely to produce vibration, and the vibration has a greater impact on the life and stability of the machine, so pay attention to the following matters when adjusting the mold: slow mold opening speed is the speed of the mold start, so the speed is Below medium speed, slow medium pressure is generally used, because the template has a certain amount of deformation to generate the clamping force, so the starting pressure can be appropriately larger, generally about 50%, and the slow position depends on the model, generally When the mold is opened to a little bit, the mold is quickly opened to reduce the mold opening time.
The rapid mold opening speed pressure can be appropriately increased to reduce the mold opening time, but the quick mold opening position and the deceleration mold opening position must be properly distanced, because the impact and inertia at the time of rapid mold opening is relatively large, and it must be a distance to eliminate The effect of inertia on the end of die opening.
However, if the separation distance is too long, the mold opening time will be prolonged, and the pressure of the deceleration mold opening speed can be adjusted to be very small, generally about 10 to 20 as long as it can support the template to overcome the minimum force of resistance. When the mold is terminated, try not to impact the rebound phenomenon. Because the acceleration at the moment of rebound is very large, the wear on the machine hinge is also very large, and the end position of the mold opening cannot be stabilized within a small range.
The rapid mode-locking speed can be appropriately large to reduce the time for moving the mold, but the pressure does not need to be too large. The quick-locking position is greater than the thickness of the product, and the position to reach the product thickness is to switch to low-pressure mode-locking. The low pressure mode-locking speed is generally controlled within 30%, the pressure is generally 0, and the special mold must also be controlled to minimize the resistance after counteracting the resistance of the mold spring/slider, etc. to achieve the purpose of low-voltage protection.
