Injection molding machine is a new way to unlock mold force

It can be said that the use of injection molding machines is the preferred method in most enterprises. The reason for using injection molding machines is mainly due to the advantages of injection molding machines. As a professional manufacturer of injection molding machines, we have a very comprehensive understanding of injection molding machines. Today, let’s explain in detail how injection molding machines unlock the mold force, The specific analysis is detailed below.

● close the mold adjusting device switch, adjust the thickness of the mold until both sides of the mold begin to be fixed, and then disconnect the mold adjusting device switch.

● manually operate the mold opening. Until the mold opening is completed, start the mold adjusting device to reduce the mold thickness and generate the mold locking force. Disconnect the mold adjusting device and operate the mold locking slowly. The reduction of the mold thickness is proportional to the generated mold locking force. However, if the mold thickness is reduced too much, the mold cannot be locked. Therefore, the mold thickness should be reduced in a gradual way.

● repeat the adjustment operation in 2) above until the machine twist and guide post generate enough clamping force. The clamping force shall not be adjusted too high, as long as it can ensure that the injection molded parts or products do not produce flash during injection molding, so as to ensure the service life of the machine.

● when adjusting the mold locking force, the express mold locking cannot be used.

● stop travel switch at “low voltage mode locking”; At the moment when the “released” mode locking stroke end stroke switch is pressed, the pressure gauge will indicate the working pressure value of the mode locking cylinder during mode locking action, and the display time is very short, which is also the reason why express mode locking cannot be used.

● the displayed working pressure is generally lower than the real pressure in the mold locking cylinder, so do not use the high rated working pressure for mold locking operation for a long time, so as to prolong the service life of the machine. Generally, the displayed working pressure should reach 80% – 85% of the high rated pressure, such as the high pressure of 145kgf / cm2, and the service pressure of 120kgf / cm2 is more appropriate.

● adjustment of low-voltage clamping force. In order to maintain the sensitivity of low-pressure mold locking, when adjusting the low-pressure mold locking force, it should be set from the numerical control value 00 of low-pressure mold locking, so that the low-pressure mold locking force is slightly higher than the resistance encountered during mold locking, and can start the high-pressure mold locking action at the same time.

● ordinary or express mold locking operation can be selected, and relevant travel switches shall be readjusted to make mold opening and mold locking operate smoothly.

This is how the injection molding machine unlocks the mold force. Of course, if you have other questions about the use of the injection molding machine, you might as well contact us directly, and we will answer any of your questions at the first time.
