How to set low pressure protection for Standard Injection Molding Machine



In the first stage, adjust the clamp pressure of Standard Injection Molding Machine to the required pressure, which can be seen in the pressure gauge. For example, we need 120 kg clamping pressure. First straighten the bent arm and adjust the thickness of the mold until the clamping pressure reaches 120 kg on the pressure gauge, and then continue to the next step.

  In the second stage, the open distance is set, the open distance is not far, and the principle is to take out the product. When setting the open buffer, the length of the buffer must be determined according to the opening speed. The faster the speed, the further the buffer zone.
  In the third stage, the first stage of slow opening is usually set according to the low pressure start position. If there is HART, wire position, etc., it is recommended to increase 5 mm according to the mold clamping position.
  In the fourth stage, the fast clamping position is usually switched from the beginning of the clamping section to the fast clamping movement, and the size of the fast end position is determined according to the accuracy of the machine. The higher the accuracy, the smaller the position. It is usually set to 20-40 mm before the low pressure position starts.
In the fifth stage, first set the high pressure pressure speed of the fixture to 0, and then use the manual fixture to confirm the position where the mold is completely attached to the front mold. For example, the front and rear mold assembly position is 1.3MM, and the setting position is usually 1.4MM. If the position is set to be the same as the actual position, it will be prone to error alarms. If it is too much, the low-voltage protection function will be lost.
In the sixth stage, the high pressure and speed are restored.

  Needless to say this action. The reply is OK. After the entire low-pressure protection setting is completed, test with white paper. The white paper is not suitable or OK, and then reduce the low-pressure position or reduce the speed pressure again. Low-voltage protection, low-voltage protection settings, the entire commissioning cycle does not exceed 5 minutes.
