Description
Technical Field
The utility model relates to a casting equipment technical field.
Background
The casting is a process of obtaining a metal forming casting by a certain method, a casting machine is adopted to cast molten iron to a sand mold die, a casting blank is obtained after the molten iron is cooled in a sand mold, in the casting operation process of a production line, sand molds molded by the sand mold molding machine are ejected out one by one from sand mold production outlets and pushed to the direction of the casting machine through a sand mold sliding channel, and the casting machine is arranged at a position close to the sand mold sliding channel, so that a pouring ladle nozzle of a pouring ladle is aligned to a sand mold pouring cup of the sand mold corresponding to the position of the sand mold sliding channel where the pouring ladle is positioned, and the pouring operation is carried out.
In the pouring process, the pouring process is stopped due to equipment faults and the like, if the stopping time is long, the relatively closed molten iron at the pouring ladle nozzle is solidified due to large temperature drop, so that the pouring ladle nozzle is blocked and the pouring operation can not be carried out, and the molten iron needs to be poured out in time in order to prevent the molten iron from solidifying in the pouring ladle and damaging the equipment; when the molten iron flow regulating rod fails and cannot plug the ladle nozzle and leaks, the pouring operation cannot be carried out, and the molten iron in the ladle needs to be poured out for maintenance.
In the pouring process, because the pouring gate in the sand mold is narrow, the pouring amount of the molten iron needs to be controlled in the process of pouring the molten iron into each casting model from the pouring gate, so that air in the casting model and vapor formed under the action of high temperature are smoothly discharged from the pouring gate, and casting loss caused by uneven molten iron inlet amount of each casting model due to overlarge pouring amount and molten iron overflow caused by serious blast at the opening of the sand mold pouring cup are prevented. And the phenomenon of part shortage caused by the fact that the casting model cannot be fully poured in the time period that the sand mold pouring cup passes through the pouring ladle nozzle due to the fact that the pouring amount is too small is also avoided.
In the pouring process, if slag adhesion is generated between the contact surfaces of the ladle nozzle and the molten iron flow adjusting core of the molten iron flow adjusting rod, the contact degree of the ladle nozzle and the molten iron flow adjusting core is damaged, so that the ladle nozzle cannot be sealed by the molten iron flow adjusting core and molten iron leakage is caused, and the condition that the slag adhesion blocking sealing is required to be cleaned in time is generated, so that accidents caused by high-temperature molten iron leakage are avoided.
In the pouring process, molten iron flows through when watering the ladle nozzle with water ladle nozzle inner wall contact part, because the difference in temperature reason can form and glue the sediment, if not in time clear up, water ladle nozzle can become narrow, and the molten iron flow diminishes, will water ladle nozzle jam gradually, if clear sediment pole and molten iron flow control stick decentraction, take place easily to interfere and lead to clear sediment pole and molten iron flow control stick card to die, can melt the adhesion even in the molten iron flow control stick.
The casting process used at present is casting by a manual casting method.
