Cylinder sleeve casting device

Abstract

The invention provides a cylinder sleeve casting device which comprises a centrifugal casting machine, a supporting main body and a vehicle body. The vehicle body is slidably connected to the supporting main body; the vehicle body comprises a shell, a molten iron container is rotatably fixed to the shell, a casting nozzle is further fixed to the side wall of the molten iron container, and a weightsensor is further arranged on a base of the shell. A working process of the cylinder sleeve casting device is as follows: when it is needed to cast, the vehicle body slides to the lower side of the centrifugal casting machine through a slideway, the adding amount of molten iron in the molten iron container is controlled according to weight displayed by the weight sensor, and molten iron at a preset weight enters a casting die along the casting nozzle to be casted to obtain a cylinder sleeve blank. By arranging the weight sensor, the adding amount of the molten iron can be controlled precisely, and the weighing and pouring step are finished efficiently, so that the cylinder sleeve casting efficiency is improved and meanwhile, a condition that the production quality of the cylinder sleeve is affected as the molten iron is cooled too quickly is avoided.

Description

technical field [0001] The invention relates to the field of cylinder liner processing, in particular to a cylinder liner casting device. Background technique [0002] The cylinder liner is a cylindrical part that is placed in the cylinder block hole of the engine block, and the piston reciprocates in the inner hole. The casting blank is the first step in the cylinder liner processing technology, and it is also a crucial step. Usually, the operator first needs to weigh the predetermined weight of molten iron, and then pour the weighed molten iron into a centrifugal casting machine for casting to form a cylinder liner blank. The above process still stays in the manual operation stage, not only the efficiency is low, but also the weighing step and dumping step take a long time, which makes the temperature of molten iron drop greatly and affects the production quality of the cylinder liner.
