One-box four-type casting process of brake disk

The invention discloses a one-box four-type casting process of a brake disk. The process comprises the following technological steps: a sand processing procedure adopts a chassis rotary type rotor sand mixing machine, sand mixing is carried out according to a sand mixture ratio, the sand mixing efficiency is 120 tons/hour, and the sand mixing time is 3-5 minutes; a moulding procedure adopts a static-pressure production line with double-host wiring for moulding and a special mould of a one-box four-type brake disk, the production efficiency is 180 boxes/hour, and the moulding pressure intensity is 8-10MPa; a smelting procedure adopts a cupola and an electric furnace for double smelting, the pouring temperature is 1450-1490 DEG C, and 0.3% of degeneracy-resisting silicon-barium nucleating agent is added before the furnace; a pouring procedure adopts an automatic pouring truck for pouring, and the pouring time is 8-15 seconds; and a desanding and shot blasting procedure adopts a vibration type desanding machine for desanding, and then a stepping type suspended connection shot cleaning chamber is used for cleaning the brake disk. The production process has the characteristics of high rate of finished products, high technological casting yield, high mechanization degree, short production period, high production efficiency, small energy consumption and the like.
