What are the debugging methods for low-pressure protection of injection molding machine? Many factories now require injection molding machine For low-voltage protection and commissioning, in fact, most technicians can not quickly and properly adjust; In this link of low voltage regulation, the machine adjustment time can be greatly saved, providing better support for production performance. Let's take a look at the low-pressure protection and debugging methods of Liansheng 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 clamping pressure, first straighten the crank and adjust the thickness of the injection molding machine mold until the clamping pressure on the pressure gauge reaches 120KG, then proceed to the next step.

2、 The mold opening distance should not be too far, and the principle is to take out the product without contacting the product; Note that when setting the mold opening buffer, the length of the buffer must be determined according to the mold opening speed. The faster the speed is, the farther the buffer area will be.

3、 The first stage of slow mold opening is generally set according to the low-voltage starting position; Note that if there is central pulling, alignment, etc., it is better to add 5MM according to the mold closing position.

4、 The quick clamping position generally turns into quick clamping action after the clamping section is started, and the size of the quick tail position is determined according to the precision of the injection molding machine; The higher the precision, the smaller the position. It is generally set 20-40MM before the start of low voltage position.

5、 First, set the high-pressure pressurization speed of the mold closing to 0, then manually close the mold, and set the number according to the position of the injection molding machine mold fully fitting the front mold. For example, the matching position of the front and rear dies is 1.3MM, and the setting position is generally 1.4MM. When the set position is the same as the actual position, it is easy to make false alarm, and too many will lose the low-voltage protection.

6、 Restore high voltage and high speed, restore to normal, complete the whole low-voltage protection setting, and test with white paper after completion; Put the white paper on the mold of the injection molding machine. After the mold is closed, slightly lower the low-pressure position or speed and pressure. The whole commissioning period shall not exceed 5 minutes.

That's it Large injection molding machine Do you understand the instructions on how to debug the low-voltage protection? I hope it will help you.
