How to maintain the cast iron pillow block bearing?

(1) Use of cast iron pillow block bearing cooling system. Cast iron pillow block bearing cooling water not only prolongs the service life of cast iron pillow block bearing, but also improves production efficiency when used correctly. The materials of cast iron pillow block bearings are generally made of special materials through various treatments, and even the best bearing seat steels have their limitations, such as temperature. When the cast iron pillow block bearing is in use, if the mold temperature is too high, it is easy to cause cracks on the surface of the mold core. Some cast iron pillow block bearings have large areas of cracks even before more than 2000 mold times appear. Even cast iron pillow block bearing in production because the bearing seat temperature is too high, the mold core has changed color, and even reached more than 400 degrees after measurement, such a temperature is prone to cracks when the release agent is chilled. Lines, the products produced are also prone to deformation, strain, mold sticking, etc. The use of mold release agent can be greatly reduced in the case of using the cooling water of the bearing seat, so that the operator will not use the mold release agent to reduce the temperature of the bearing seat. Its advantages are to effectively prolong the life of the bearing seat, save the die-casting cycle, improve the product quality, reduce the occurrence of mold sticking, strain and aluminum sticking, and reduce the use of mold release agents. It can also reduce the loss of the ejector pin and core due to overheating of the bearing seat.

(2) The cast iron pillow block bearing must preheat the bearing seat during the production process to prevent the occurrence of cracks caused by the sudden encounter with the hot metal liquid in the cold cast iron pillow block bearing. The iron pillow block bearing can use a blowtorch, liquefied gas, and a mold temperature machine in good conditions. The relatively simple cast iron pillow block bearing can be preheated by slow injection.

(3) The cleaning of the parting surface of the cast iron pillow block bearing is very troublesome and easy to ignore. The operator should thoroughly clean the parting surface of the bearing seat with kerosene, which can not only prevent the bearing seat from being damaged. Squeeze injury, and after cleaning, it can open the exhaust groove blocked by the residue of mold release agent or other dirt on the cast iron pillow block bearing, which is conducive to the discharge of gas in the cavity during the injection process and improves the quality of the product.
