Bearing divided: Split bearing, sliding bearing, bearing seat, bearing, spherical bearing, etc. with flange. Bearing points should pay special attention in the course of the following: (1) the use of the bearing cooling system. Bearing cooling water in case of proper use of not only prolong the life of the bearing, and improve production efficiency. Bearing materials are generally dedicated bearing steel produced by various processes, even the best bearing steel also have their limits on the use of, like on temperature. Bearing in use, if the mold temperature is too high, it's easy to make the mandrel surface crack turtle appear early, some even bearing no more than 2,000 die times Tortoise on a large area. Even bearing in production bearing temperature is too high because the core has changed color, after measuring even reached four hundred degrees, so the temperature of the release agent chilling encounter under state is very prone to crack turtle, production The products are easy to deformation, strain, sticky mold such a situation. In the case of the bearing cooling water can be greatly reduced use of release agent, so the operator does not use a release agent to lower the temperature of the bearing. The advantage is that prolong bearing life, saving die-casting cycle, improve product quality, reduce strain and sticky mold and aluminum sticky situation occurs, reduce the use of release agent. But also to reduce the bearing temperature overheat and cause ejector and core losses.
