Pay special attention to the following points during using the bearing seat:

(1) Use of bearing seat cooling system. When the bearing seat cooling water is used correctly, it not only prolongs the service life of the bearing seat, but also improves production efficiency. The material of the bearing seat is generally made of special 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 tortoise cracks on the surface of the mold core early. In some bearing seats, the tortoise cracks appear on a large scale even before more than 2000 molds. Even in the production of the bearing seat, the color of the mold core was changed due to the too high temperature of the bearing seat. After measurement, it even reached more than 400 degrees. This temperature is prone to cracks when it is quenched by the release agent. The products are also prone to deformation, strain, and mold sticking. In the case of using the bearing seat cooling water, the use of release agent can be greatly reduced, so that the operator will not use the release agent to reduce the temperature of the bearing seat. The advantage is to effectively extend the life of the bearing seat, save the die-casting cycle, improve product quality, reduce mold sticking, strain and aluminum sticking, and reduce the use of mold release agents. It can also reduce the loss of ejector rod and core caused by overheating of the bearing seat.

(2) The bearing seat must be preheated during the start of production to prevent the occurrence of turtle cracks when the cold bearing seat suddenly encounters hot molten metal. The more complicated bearing seat can be liquefied by a blowtorch. If the condition is good, use a mold temperature machine, and the relatively simple bearing seat can be preheated by slow injection.

(3) Cleaning the parting surface of the bearing seat is very troublesome and easy to overlook. The operator should thoroughly clean the parting surface of the bearing seat with kerosene, which not only prevents the bearing seat from being crushed, but also Moreover, after cleaning, the exhaust grooves on the bearing seat that are blocked by the residue of the release agent or other dirt can be opened, which is beneficial to the discharge of the gas in the cavity during the injection process and improves the product quality.

(4) If the bearing seat is equipped with neutron control, it is absolutely forbidden to connect the signal line between the die casting machine and the bearing seat. The reason is clear. In daily production, it is difficult to avoid water on the signal line or The place where the joint is wrapped is easy to break, resulting in short-circuit with the machine tool. If the signal is wrong, the alarm will automatically stop and delay the time, and the signal will be disordered and the bearing housing will be damaged. Cause unnecessary losses. Pay attention to waterproof of travel switch.
