Injection molding machines are also called injection molding machines or injection molding machines. There are vertical, horizontal, and vertical-horizontal compound types. So what should we do if our high-quality injection molding machine fails semi-automatically?
The semi-automatic operation of the high-quality injection molding machine is by opening the safety door, closing the stroke switch, and sending a signal to start the semi-automatic action of the machine, and then closing the mold. After encountering the SQ4 stroke switch, the mold closing ends and the injection starts at the same time. The injection time relay starts timing and the injection time When the time is up, the pre-molding starts, and when it touches the limit switch that has finished pre-molding, it starts to prevent flow. When it touches the anti-flow limit switch, the cooling time relay starts timing. After the time is up, the mold opens, and then the mold opens.
After the mold opening terminates the stroke switch, perform the ejection action. After the ejection termination stroke switch is touched, the ejection action is performed. After the ejection termination stroke is encountered, the safety door is waited to open, so that the work is repeated. It can be seen from the above that if the manual operation is normal, it is usually caused by the trip switch and time relay not sending a signal. According to the failure of the semi-automatic action in the mechanical cycle, compare the electrical appliances and the hydraulic schematic diagram to find out the corresponding control components, and check to solve them.More about:Injection Molding Machine
