Abstract

The invention relates to a lost foam casting die and method for a braking disc and belongs to the technical field of lost foam casting and aims to solve the technical problem of short service life. According to the lost foam casting die and method for the braking disc, lost foam casting is adopted, the hardness of a friction surface of the braking disc is uniform and the service life is long. According to the technical scheme, the lost foam casting die comprises an upper die, a lower die and a semi-circular casting lost foam pattern, wherein cavities are formed in inner surfaces of the upper die and the lower die, a casting cavity is formed between the upper die and the lower die after the upper die and the lower die are buckled, the semi-circular casting lost foam pattern is arranged in the casting cavity, multiple movable blocks are arranged in the semi-circular casting lost foam pattern, and sprue gates are formed in tops of the upper die and the lower die. The lost foam casting die and method for the braking disc are widely used for casting of the braking disc.

Description

Technical field [0001] The invention relates to a brake disc lost foam casting mold and a lost foam casting method thereof, belonging to the technical field of lost foam casting. Background technique [0002] In the traditional casting process (sand casting) casting, due to the limitations of the process, the two friction surfaces of the brake disc are one on the upper side and the other on the lower side. After pouring, the cooling rate of the two surfaces is different, which causes the product to be used, The wear degree of the two surfaces is very different, which cannot meet the technical requirements of service life. Summary of the invention [0003] In order to solve the technical problem of poor service life in the prior art, the present invention provides a brake disc lost foam casting mold with simple process, using lost foam casting, uniform brake disc friction surface hardness, and long service life and its disappearance Mold casting method. [0004] In order to achieve...
