Maintenance and upkeep of plastic bearing seat F206 bearing seat

Special attention should be paid to the following points during the use of the bearing seat:

(1) The use of bearing seat cooling system. When used correctly, the cooling water for the bearing seat not only extends its service life, but also improves production efficiency. The material of the bearing seat is generally made of specialized bearing seat steel through various treatments, and even the best bearing seat steel has its limits of use, such as temperature. When the bearing seat is in use, if the mold temperature is too high, it is easy to cause early cracks on the surface of the mold core. Some bearing seats even have large areas of cracks before exceeding 2000 mold cycles. Even the mold core of the bearing seat changes color during production due to the high temperature of the bearing seat. After measurement, it even reaches over 400 degrees Celsius. When exposed to the cold state of the release agent at such temperatures, it is easy to develop cracks, and the produced products are also prone to deformation, strain, and mold sticking. When using cooling water for the bearing seat, the use of release agents can be greatly reduced, so that operators will not use release agents to lower the temperature of the bearing seat. Its benefits lie in effectively extending the life of the bearing seat, saving the die-casting cycle, improving product quality, reducing the occurrence of mold sticking, pulling, and aluminum sticking, and reducing the use of release agents. It can also reduce the loss of the top rod and core caused by overheating of the bearing seat temperature.

(2) During the production process, the bearing seat must be preheated to prevent the occurrence of turtle cracks caused by sudden contact with hot metal liquid in cold bearing seats. For more complex bearing seats, spray lamps and liquefied gas can be used, and for better conditions, mold warmers can be used. For simpler bearing seats, slow injection preheating can be used.

(3) Cleaning the parting surface of the bearing seat is very laborious and easy to overlook. Operators should thoroughly clean the parting surface of the bearing seat with kerosene, which not only prevents the bearing seat from being squeezed, but also opens up the exhaust groove blocked by residual release agent or other dirt on the bearing seat after cleaning, which is conducive to the discharge of gas from the cavity during the injection process and improves product quality.

(4) If the bearing seat is equipped with neutron control, it is absolutely forbidden for the signal line between the die-casting machine and the bearing seat to have a joint phenomenon. The reason is very clear. In daily production, it is difficult to avoid the signal line getting wet or the joint wrapping being easily broken, which can cause a short circuit with the machine tool. If a signal error is caused, it may trigger an alarm and automatically stop the machine, delaying time. In severe cases, the signal may become chaotic and damage the bearing seat. Causing unnecessary losses. Pay attention to waterproofing of the travel switch
