Novel casting mould structure for car brake disc
2013
The invention provides a novel high-strength casting mould structure for a car brake disc. The novel casting mould structure is formed by compounding two outer moulds and a sand core, wherein the sand core is located in the outer moulds. According to the novel casting mould structure, the strength, the toughness, the weather resistance and the processability of a rear brake disc for a car are improved. A micro-alloy vanishing ring is additionally arranged at an R angle part which easily generates inner looseness in the casting mould so as to improve the strength and the toughness of a casting. The casting is commonly molded by the sand moulds and the sand core; a casting system is arranged in the sand core; a ceramic filtering sheet, an annular liquid inlet sheet, a chilling block and a dead head of the casting system are arranged reasonably so that the defects of the casting are improved and the product quality is improved.
