The working procedure of injection molding has been determined by the line itself

Generally, Dalian injection molding can be operated manually, semi-automatic and fully automatic. Manual operation is in a production cycle, each action is realized by the operator turning the operation switch. Generally, it is only selected when commissioning and mold adjustment; During semi-automatic operation, the machine can automatically complete the action of one working cycle, but after each production cycle, the operator must open the safety door, remove the workpiece, and then close the safety door before the machine can continue the production of the next cycle.


During fully automatic operation, the injection molding machine can automatically enter the next working cycle after completing the action of one working cycle. The semi-automatic and full-automatic working procedures have been determined by the line itself. The operator only needs to change the speed and pressure, the length of time, the number of thimbles, etc. on the electric cabinet, so as not to confuse the working procedures due to the operator's wrong key adjustment.


Before each action in a cycle is not adjusted properly, select manual operation first, and then select semi-automatic or full-automatic operation after confirming that each action is normal. According to whether the injection seat retreats before and after pre plastic feeding, that is, whether the nozzle leaves the mold, the injection molding machine is generally equipped with three options. After the injection, the injection seat retreats, the nozzle leaves the mold, and then the injection seat advances after the pre molding.


This action is suitable for processing plastics with particularly narrow molding temperature. Due to the short contact time between the nozzle and the mold, the loss of heat and the solidification of molten material in the nozzle hole are avoided. After the injection is completed and the cooling timer is timed, the pre molding action starts. The screw rotates to melt and squeeze the plastic in front of the screw head.


When the screw moves backward to press the stop switch, the backward retraction stops. Then the injection seat began to retreat. When the injection seat retreats to press the stop switch, the injection seat stops retreating. If fixed feeding mode is adopted, pay attention to adjust the position of travel switch. Generally, fixed feeding mode is adopted in production to save the operation time of injection seat advance and retreat and speed up the production cycle.
