1. Turn on the switch of the mold adjustment device, adjust the thickness of the mold until the two sides of the mold begin to be fixed, and then turn off the switch of the mold adjustment device. 2.

1. Turn on the switch of the mold adjustment device, adjust the thickness of the mold until the two sides of the mold begin to be fixed, and then turn off the switch of the mold adjustment device.

2. Manually operate the mold opening. When the mold opening is finished, start the mold adjustment device to reduce the mold thickness to produce the clamping force, disconnect the mold adjustment device, and slow the mold clamping operation. The reduction of the mold thickness and the clamping force generated However, if the mold thickness is reduced too much, the mold cannot be locked. Therefore, the mold thickness must be reduced in a gradual manner.

3. Repeat the adjustment operation of 2 above until the machine strand and the guide post produce sufficient clamping force. Do not adjust the clamping force too high, as long as it can ensure that the injection molded parts or products do not produce flash during injection molding. Can guarantee the service life of the machine.

4. When adjusting the clamping force operation, the express clamping cannot be used.

5. At the moment when the "low pressure mold clamping termination stroke switch, is released", the mold clamping stroke termination stroke switch is pressed and closed, the pressure gauge will indicate the working pressure value of the mold clamping cylinder during the mold clamping action, and the display time is very short. The reason why the express mode locking cannot be used.

6. The displayed working pressure is generally lower than the real pressure in the clamping cylinder. Therefore, do not use the highest rated working pressure for a long-term clamping operation to extend the service life of the machine. Generally, 80%-85% of the highest rated pressure is suitable for the displayed working pressure. For example, the maximum pressure of 145kgf/cm2 is selected to be 120kgf/cm2.
