Do you know how to operate a horizontal plastic injection molding machine?

1、 Startup inspection
The operator needs to check the power cord for leakage before turning on the switch of the horizontal plastic injection molding machine. In addition, it is also necessary to acknowledge whether the hydraulic oil level is sufficient and check if the proximity switch of the safety door is malfunctioning.
2、 Mold installation
1. The mold must be installed manually, and the safety door shall be closed with the centering of the fixed plate, and then the equipment shall be adjusted to close the mold.
2. When adjusting the mold, ensure that the nozzle is in the center position of the gate sleeve, align it up, down, left, and right, and then fix the mold on the fixed plate.
3. Adjust the travel and speed of the ejector pin as short as possible. If the travel of the ejector pin does not comply with relevant regulations, mold damage may occur.
4. Adjust the mold closing safety equipment.
3、 Manual operation process of horizontal plastic injection molding machine
1. Switch the operating switch to the "manual" position, and then press the pump start button.
2. Close the safety door, switch the mold switch to the "mold closing" position, and start the mold closing action.
3. Switch the ejection device to the "travel" position and complete the nozzle touch.
4. Switch the ejection device to the "ejection" position, and then perform the ejection action, converting the pressure from the ejection pressure (i.e. primary pressure) to secondary pressure. Attention: To avoid screw damage, it is necessary to start the screw drive motor 15 minutes after the heating cylinder reaches the set temperature.

5. Measure the pressure holding time.
6. Switch the screw switch to the "rotation" position for metering.
7. Switch the ejection device switch and the ejection device will retreat to the appropriate position.
8. After measuring the cooling time, switch the mold switch to "mold opening".
9. End by pressing the 'Eject' button.
4、 Active operation process of horizontal plastic injection molding machine
1. Before entering active operation, set the timer and switch the operation selection switch to "semi active".
2. After acknowledging the safety of the operating environment, close the safety door.
3. Switch from low pressure mold closing to high pressure mold closing during mold closing.
4. When the clamping pressure rises, the injection equipment will move forward and the injection nozzle will start after touching the end.
5. When the timer of the ejection device reaches the set time, cooling and material will begin to be measured, and the screw will also rotate while retreating.
6. Reduce the pressure inside the closed mold cylinder and then proceed with the mold opening action.
7. After the mold opening action stops, perform the ejection action. At this moment, the product is ejected by the ejector pin and falls onto the product falling board.
During the operation of the horizontal plastic injection molding machine, if urgent shutdown is required, the "Emergency Stop Button" on the operation panel should be immediately pressed. End, after the operation, turn off the power supply and clean the machine to ensure the safety of the equipment.
