Operation of horizontal
Injection Molding Machine 1. Boot check
Check the power cord before turning on the power supply, confirm that the hydraulic oil is sufficient and check whether the close switch of the safety door is out of order and whether the switch of the safety door is smooth.
2. Install the mould, it must be operated manually
The die is matched to the fixed circle of the fixed plate to close the safety door, and the mold switch is switched to the mold setting adjustment to carry out the die.
Adjust the mold so that the center of the nozzle as far as the nozzle up and down, left and right alignment, after the horse, the mold will be fixed on the fixed plate.
Adjust the stroke and speed of the thimble, the stroke of the thimble may damage the mold when the stroke is overrun. So at first, you have to set it a little shorter.
3. Adjust the safety device of the die.
Manual operation of molding operation
Switch the operation selection switch to the Manual position, and then press the pump enable button.
The safety door on the left should also be closed.
The die switching switch switches to the "die mode", then the action of the die mode begins and the high voltage is completed.
The ejector switches to "forward" and the nozzle contact is completed.
When the ejector switch switches to "eject", the ejection action is carried out, and the pressure is converted from the ejection (primary) pressure to the secondary pressure. Note: turn on the screw drive motor 15 minutes after the temperature of the heating cylinder reaches the set temperature to avoid damage to the screw.
4. Measure the holding time of the pressure.
Switch the screw switch to the "rotating" position and measure it.
Switch the ejector switch and back the ejector to the appropriate position.
After measuring the cooling time, switch the mold switch to "open mode".
Press the ejection switch to measure the finished product.
5. Automatic operation of molding operation
First from the manual operation, so that the molding conditions are stable, and then automatic operation into the molding operation. Before entering the automatic operation, set each timer and convert the operation selection switch to "semi-automatic" when it is to be formed by automatic operation.
After confirming the security for four weeks, close the security door.
When the die is closed, it will be converted from low pressure die to high pressure die on the way.
When the closing pressure is confirmed, the ejector advances.
After the nozzle contact is completed, the ejection begins, and when the ejection time timer is counted, the ejection and pressure holding are carried out.
When the ejection time timer reaches the set time, it begins to cool and measure the injection material. The screw rotates and retreats.
When the injection stops the contact of the proximity switch, the device is stretched out and retreated.
When the cooling time timer arrives, the pressure in the closed mold cylinder drops and then the mode opening action is carried out.
After the close switch contact is stopped, the opening mode action stops.
Then the ejection action is carried out, at which time the finished product is ejected from the thimble and falls on the falling plate of the finished product.
When the finished product is used to drop the plate, the fall of the finished product can be detected and enter the beginning of the next cycle.
In the mechanical operation, if you want to stop urgently, immediately place the "emergency stop buckle" next to the side of the operating disk or anti-operating disk.
6. Stop the machine
When the use of resin is easy to produce thermal decomposition, first stop the supply of materials and shoot out all the resin in the ejection cylinder, in order to avoid the resin left in the ejector cylinder and cause thermal decomposition. At this point, in the next mold operation, the resin hot cylinder temperature must be careful, because sometimes MELTON resin will be scattered.
At the end of the operation and at the end of the operation, in order to ensure safety and protect the electrical devices, please remove the power supply and clean up the machine.
