How to set the low pressure protection of the injection molding machine?

Many injection molding machine manufacturers pay attention to low-voltage protection and debugging. Most of the technicians can't do the low-pressure adjustment quickly and well, so how to set the low-pressure protection of the injection molding machine?

1. Adjust the clamping pressure to the required pressure, which can be seen from the pressure gauge. For example, if we need 120KG mold clamping pressure, first straighten the crank arm and adjust the mold thickness until the mold clamping pressure reaches 120KG on the pressure gauge and then go to the next step.

2. Set the mold opening distance The mold opening distance is not as far as possible, and the principle is to take out the product without touching it. Note that setting the mold opening buffer must be based on the mold opening speed to determine the length of the buffer. The faster the speed, the farther the buffer will be. 3. The first stage of the mold opening slow speed is generally set according to the low pressure starting position. Note that if there is a pull-out, row position, etc., it is better to increase 5MM according to the mold clamping position.
 
4. The quick position of the mold clamping is generally switched to the quick clamping action when the clamping is started. The size of the quick end position is determined according to the accuracy of the injection molding machine. The higher the accuracy, the smaller the position. It is generally set 20---40MM before the start of the low pressure position.
 
5. Set the clamping high pressure speed to 0 first, and then manually lock the mold. Set as much as you want to see where the mold is completely attached to the front mold. For example, the front and rear mold bonding position is 1.3MM, and the setting position is generally 1.4MM. If the set position is the same as the actual position, it is easy to alarm by mistake. If it is too much, the low-voltage protection function will be lost.
 
6. Restore high pressure and speed.
Needless to say this action. Reply is OK. The entire low pressure protection setting is completed. After completion, test with white paper. If the white paper does not close the mold, it is OK. After closing the mold, reduce the low pressure position a bit or reduce the speed and pressure. The entire debugging cycle does not exceed 6 minutes.

If the low pressure adjustment of the injection molding machine is completed, it can greatly save the adjustment time and provide better support for the production of the injection molding machine.
