Automatic casting mechanism for centrifugal casting of internal combustion engine cylinder sleeve

Abstract

The invention discloses an automatic pouring mechanism for centrifugal casting of cylinder liners of internal combustion engines. The flow package is carried on the longitudinal traveling mechanism to move back and forth longitudinally, and the pouring bag is carried on the transverse traveling mechanism to move back and forth laterally. Compared with the prior art, the beneficial effects of the present invention are: (1) The pouring ladle walks by itself, and the ladle is turned over automatically, which can not only reduce the labor intensity of workers, but also improve the working environment and working conditions on site, and automatically With induction and weighing device, realize automatic operation, precisely control the inclination angle of the pouring ladle, so that the metal liquid flows out evenly; (2) The metal liquid flows into the mold cavity evenly through the through hole under the horizontal groove, avoiding strong impact on the mold cavity a part of the body from causing damage.

Description

technical field [0001] The invention relates to the technical field of cylinder liner processing equipment, in particular to an automatic pouring mechanism for centrifugal casting of an internal combustion engine cylinder liner. Background technique [0002] Centrifugal casting is a technology and method of injecting liquid metal into a high-speed rotating cavity so that the molten metal fills the cavity and forms a casting under the action of centrifugal force. Centrifugal force enables the liquid metal to fill the cavity well in the radial direction and form the free surface of the casting; a cylindrical inner hole can be obtained without a core; it is helpful for the removal of gas and inclusions in the liquid metal; it affects the crystallization process of the metal , thereby improving the mechanical and physical properties of the casting. [0003] The centrifugal casting of the prior art mainly pours the molten metal into the cavity through the pouring ladle and the l...

AI Technical Summary

Problems solved by technology

[0003] The centrifugal casting of the prior art mainly pours the molten metal into the cavity through the pouring ladle and the launder, and then carries out the next casting process, but the following problems exist in the existing pouring process: 1. Due to the large weight of the molten metal , manual pouring consumes physical strength, and it is not easy to control the tilting rate of the pouring ladle. When the pouring rate is too fast, the molten metal is easy to overflow from the cavity; 3. For horizontal centrifugal casting, the launder of the prior art directly passes through the insertion type The horizontal part in the cavity is poured, and the molten metal can only flow out from the end of the horizontal part. The molten metal strongly impacts a certain fixed point of the cavity, which damages the anti-corrosion material at this point.
