How to adjust the vertical injection molding machine clamping force

When the vertical Injection Molding Machine, when used, will encounter problems adjusting clamping force, which is not only related to whether the normal production and machinery to produce products to meet the requirements, the more important is the right adjust the mechanical clamping force can prolong machinery life.

So, how to adjust the Vertical Injection Molding Machine clamping force? Here the specific analysis:

1, co-regulated switch-mode device, mold thickness adjustment capacity on both sides of the mold until the beginning of the fixed date, then disconnect the device transfer mode switch.

2, manually operated model, to make the mold open until the start transfer mode means reducing mold clamping force generated thick, disconnect the device transfer mode, slow mode-locked operation mode to reduce the thickness of the clamping force generated proportional, but if the mold thickness decrease too much, it can not clamping, therefore, we should take a progressive approach to reduce mold thick.

3. Repeat the above 2) adjusting operation until the machine twisted and guide post to generate sufficient clamping force until the clamping force is not so high, as long as the guarantee for injection molding injection molded parts or products can not produce flash, this ensures that the service life of the machine.

4, adjusting the clamping force to operate, you can not use express mode locking.

5, in the "low-pressure clamping termination limit switch; is released" Clamping stroke termination limit switch is pressed together at the moment, the pressure gauge will indicate clamping action clamping cylinder working pressure, the display time is very short, but also Express clamping reason can not be used.

6, showing the working pressure is generally more than the true pressure inside the lower clamping cylinder, it is not long-term use of the maximum rated working pressure clamping operation, to extend the life of the machine. The operating pressure generally exhibit the highest rated pressure 80% -85% is appropriate, such as maximum pressure 145kgf / cm2 have selected to 120kgf / cm2 pressure is more appropriate.

7, low clamping force is adjusted in order to maintain a low pressure clamping sensitivity, low pressure when adjusting the clamping force, low pressure should begin clamping numerical value 00 is set so that the clamping force is slightly higher than the low-pressure clamping encounter resistance, while starting to reach high pressure clamping operation.

8, can use an ordinary or express clamping operation to re-adjust the relevant limit switch for use with a mold clamping operation so smoothly.
