Method for adjusting clamping force of strap injection machine

11-01-2020

Strap injection machine is one of the common equipment in injection molding machine. In practical applications, it is mainly widely used in plastic products industry. However, when the strap injection machine is in use, it will encounter the problem of adjusting the clamping force. This is not only related to the normal production of the machine and whether the products produced meet the requirements. It is more important to properly adjust the clamping force of the machine. Extend the life of the machine. So, how to adjust the clamping force of the strap injection machine? Let's take a look at it together.


  1. Close the switch of the mold adjustment device of the strap injection machine, adjust the thickness of the mold holder until both sides of the mold begin to be fixed, and then turn off the switch of the mold adjustment device.


  2. Manually open the mold. Until the mold is opened, start the mold adjustment device to reduce the mold clamping force, and disconnect the mold adjustment device to slow the mold clamping operation. The reduction in mold thickness and the generated clamping force Proportional, but if the mold thickness is reduced too much, the mold cannot be locked, so the mold thickness should be reduced in a gradual manner.


  3. When adjusting the clamping force of the strap injection machine, you cannot use express clamping.


  4. In the strap injection machine, the "low pressure clamping termination stroke switch; when released" the mold clamping stroke termination stroke switch is pressed, the pressure gauge will indicate the working pressure value of the clamping cylinder when the clamping action is performed, and the time will be displayed. Very short, which is why you cannot use express clamping.


  5. Adjustment of low-pressure clamping force In order to maintain the sensitivity of low-pressure clamping, when setting the low-pressure clamping force, the numerical value 00 of the low-pressure clamping should be set to make the low-pressure clamping force slightly higher than that encountered during clamping. Resistance, and at the same time can achieve the start of high-pressure mold clamping action.


  6. Ordinary or express clamping operation can be selected. Relevant stroke switches should be readjusted so that the mold opening and clamping operation can be performed smoothly.


  The above is the introduction of the clamping force adjustment method of the strap injection machine. I hope that everyone will be helpful after understanding the clamping force adjustment method of the strap injection machine.
