Mould opening is more prone to vibration, and the service life of the machine has a great impact on vibration and stability, so when adjusting the locking mode, please pay attention to the following points: Slow die opening is the beginning of the speed of the mould, so the speed is in the middle speed, generally the use of moderate pressure is slow, because when the clamping template has a certain deformation, it produces clamping force, so the starting pressure can be appropriately larger, generally. At about 50%, the slow position depends on the model, usually at a point in the die, in order to reduce time and rapid die opening.
Fast speed die distance can increase and decrease die hole properly, but the position of rapid die hole and speed-up die hole must reduce the opening time properly, because the influence of rapid die hole and inertia is relatively large, a certain distance must be taken to eliminate inertia affecting the position and termination of die hole.
However, if the interval distance is too large, the opening time will be prolonged, and the speed and pressure of decelerating the opening can be adjusted to a very small level, generally around 10-20, so long as the minimum power can support the die to overcome resistance. As far as possible, there should be no impact rebound at the bottom of the die. Because the instantaneous acceleration of springback is very large, the wear of machine hinges is also very large, and the position of opening and terminating can not be stabilized in a small range.
Fast clamping speed can be properly increased to reduce die changing time, but it does not need too high pressure. Fast clamping position should be larger than product thickness, and low pressure clamping position should be changed to reach product thickness. Low-pressure clamping speed is generally controlled within 30%, pressure is generally 0, and special die is controlled to minimize the resistance of die spring/slider, so as to achieve the purpose of low-pressure protection.
