Computer-based medical equipment mold opening

This is a common problem of Haitian machines. If you have consulted Haitian after-sales, you will know that 1 all machines have tolerances, but the tolerance of Haitian machines is the largest among all the machines I have used. When in use, no matter how the recoil pressure, speed and the position of the penultimate engine change, whether it is automatic or manual, it will exceed or be less than the set value. At the same time, it depends on the size of the mold, and the tolerance is generally about 5 mm, which is a brake system problem in the machine. It is a temporary problem of Haitian hydraulic press. It might be better if Haitian servo machine is used (I have never used Haitian servo injection molding machine).

Hello. I have never used Haitian servo. I consulted engineer Liu of Shanghai Haitian after-sales maintenance department today. He said that apart from the process, its mold opening is controlled by computer, so it is not easy to check from the circuit and there is no mechanical problem.

what do you think? Do three mold opening experiments with empty machine (no mold) and ordinary mold, and show me the actual position of mold opening for your reference. In addition, I have used Sumitomo's servo, which often doesn't open in place, and there is metal friction. That's because the screw and shaft sleeve of the crank arm are broken, because the bearing outside the shaft sleeve has not been oiled for a long time. You can refer to it
