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 please 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 a certain amount of deformation of the stencil during clamping is used to generate the clamping force. Therefore, the starting pressure may be appropriately larger, generally about 50%, and the slow position may depend on the model. When the mold is opened to a little bit of position, the mold is quickly opened to reduce the mold opening time.
The speed of the quick mold opening can be appropriately increased to reduce the mold opening time. However, the mold opening position and deceleration mold opening position must be properly distanced. Because the impact and inertia during rapid mold opening are relatively large, a certain distance must be used to eliminate the mold opening time. The effect of inertia on the position of the die termination.
However, if the separation distance is too long, the mold opening time will be prolonged, and the deceleration mold opening speed pressure can be adjusted to be very small, generally around 10-20 as long as it can support the template to overcome the minimum resistance force. Do not have a 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 die opening position cannot be stabilized within a small range.
The rapid mold clamping 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 mold clamping position is greater than the product thickness, and the position to reach the product thickness is to switch to low pressure mold clamping. The low pressure mold clamping speed is generally controlled. In 30% or less, 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 and so on, so as to achieve the purpose of low voltage protection.
