How to deal with the abnormality of the injection molding machine?

No matter how high-quality injection molding machines are used for a long time, abnormal phenomena will occur, and abnormalities will occur in the following parts, such as gas lines, lack of material, and so on. In the presence of gas marks, the measures that need to be taken are to increase the temperature of the mold, increase the temperature of the barrel, or reduce the shooting speed and injection pressure at the gate location. In the case of a shortage of materials, it is first necessary to check whether the dosage of the product is sufficient. If there is a lack of material in the thick part of the product, the temperature of the back mold will be too high, resulting in poor exhaust. The measures that can be taken for this phenomenon are to reduce the temperature of the mold and increase the injection rate. However, when the product is short of materials due to the encapsulation position, what is needed is to improve the exhaust environment and reduce the rate of fire. When there is a shortage of material in the product, check the nozzle to see if there is any leakage, blockage, and whether the temperature of the material tube is abnormal. What should I do if a high-quality injection molding machine fails semi-automatically? The semi-automatic operation of 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 anti-flow. When it touches the anti-flow limit switch, the cooling time relay starts timing. When the time is up, the mold opens, and then the mold is opened. After the mold-opening termination travel switch, perform the ejection action. After the ejection termination travel switch is encountered, perform the ejection action. After the ejection termination travel switch is encountered, wait for the safety door to be opened. In this way, 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. www.highsun-machinery.com
