Bearing seat in the course of the following should pay particular attention to:(1) the use of the bearing housing cooling system. Chock cooling water in the proper use of the case not only to extend the service life of the bearing, and improve production efficiency. The chock Steel bearing materials are generally dedicated by various treatment produced, no matter how good the bearing seat steel also have their limit, such as temperature. The bearing seat in the state of use, and if the mold temperature is too high, it is easy it will make the surface of the mold core early turtle cracks, some bearing seat is not more than 2000 die times crack turtle even on a large area. Even chock chock temperature is too high mold core has changed color or even reach more than 400 degrees, after measuring this temperature release agent chilling encounter in production can easily crack turtle production The products are also easy to deformation, strain, stick mold situation. In the case of using the cooling water of the bearing seat, the use of the release agent can be greatly reduced, so that the operator would not use the releasing agent to the temperature of the lower bearing seat. The benefit is to extend the effective life of the bearing housing, to save die casting cycle, improve product quality, reduce the occurrence of the sticky mold and strain and sticky aluminum, reduce the use of mold release agents. Can reduce the temperature of the bearing seat overheating caused by the loss of the plunger and the core.(2) chock begin production process must be chock preheating to prevent cold bearing suddenly encountered hot liquid metal and lead to the emergence of crack turtle, complex bearing with a blowtorch, liquefied gas, the conditions are good, with the die temperature, relatively simple bearing can take advantage of the slow shot preheat.(3) of the bearing block parting surface cleanup, it is very cumbersome, and it is very easy to overlook, operatives application kerosene thorough cleaning of the bearing housing parting surface again, not only to prevent the bearing seat will not be Jishang bearing seat release agent residue or other dirt clogging the exhaust ducts and after cleaning, can get through, is conducive to the injection process medium-sized cavity gas discharged improve the product quality.(4) If the bearing seat is equipped with a neutron control, pay attention to the absolute prohibition of signal lines between the die casting machine bearing joints phenomenon, the reason is very clear, the signal line, it is difficult to avoid the water on in the day-to-day production, or the place connector bandage easy to break, resulting in a short circuit with the machine, if caused by a signal error, ranging from Automatic shutdown delay time, while signal disturbance to the top of the bearing housing bad. Resulting in unnecessary losses. Travel switch waterproof .
