The turntable bearing seat has a compact structure, sensitive rotation, and easy maintenance of the equipment. Compared with ordinary bearing seats, the turntable bearing seat should pay special attention to the following points during use:

(1) The use of bearing seat cooling system. When used correctly, the cooling water of the bearing seat not only extends the service life of the bearing seat, but also improves production efficiency. The bearing seat material is generally made of specialized bearing seat steel through various treatments, and even the best bearing seat steel has its usage limit, such as temperature. In the use state of the bearing seat, if the mold temperature is too high, it is easy for early cracks to appear on the surface of the mold core. Some bearing seats even have large cracks before 2000 mold cycles. Even in the production of bearing seats, the color of the mold core changes due to the high temperature of the bearing seat, and even reaches over 400 degrees after measurement. At this temperature, the release agent is prone to cracking when cooled, and the product is prone to deformation, tearing, and sticking to the mold. The use of cooling water for the bearing seat can greatly reduce the use of release agents, preventing operators from using release agents to lower the temperature of the bearing seat. Its advantages are that it can effectively extend the service life of the bearing seat, save the die-casting cycle, improve product quality, reduce mold sticking, pulling and aluminum sticking, and reduce the use of release agents. It can also reduce the loss of 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, attention should be paid to prohibiting the signal line between the die-casting machine and the bearing seat from having a joint phenomenon. The reason is very clear. In daily production, it is difficult to avoid the signal line from getting wet, or the joint wrapping is easy to break, resulting in a short circuit with the machine tool. If the signal is incorrect, it may cause an alarm and automatic shutdown, delaying time. In severe cases, the signal may become chaotic and damage the bearing seat. Causing unnecessary losses. Pay attention to waterproofing for the travel switch.
