Problems solved by technology

[0004] However, the existing twin sand core box casting molds for brake disc blanks have poor air permeability, uneven heating, and a square mold structure, resulting in more materials used and heavier weight. Therefore, we propose a resin sand core for brake disc blanks. Box casting mold and grinding wheel manufacturing process

Abstract

The invention discloses a brake disc blank coating sand core box casting mold. The brake disc blank coating sand core box casting mold comprises an upper mold, wherein a lower mold is installed at thebottom of the upper mold, a sand shooting head is installed at the center of the upper mold, the center of the sand shooting head is a sand shooting nozzle, the bottom of the sand shooting head is connected with a sand core, the sand core is installed at the center of the top of the lower mold, a first heating pipe is fixed to the edge side of the upper mold, and a second heating pipe is fixed tothe edge side of the lower mold; the first heating pipe and the second heating pipe are arranged and are distributed at equal angles with respect to the central axes of the upper mold and the lower mold, then the heat generated by the first heating pipe and the second heating pipe can be uniformly distributed in the upper mold and the lower mold, the molding quality of the sand core is guaranteed, and meanwhile, the first heating pipe and the second heating pipe can discharge the gas inside the upper mold and the lower mold.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a casting mold of a brake disk blank coated with a sand core box and a manufacturing process of a grinding wheel. Background technique [0002] Disc brakes use a stationary brake disc to clamp the brake disc that rotates with the tire on the wheel to generate friction and reduce the speed of the wheel. When the brake pedal is depressed, the piston in the master cylinder is pushed, which builds up pressure in the brake fluid circuit. The pressure is transmitted to the piston of the brake cylinder on the brake caliper through the brake fluid. After the piston of the brake cylinder is under pressure, it will move outward and push to make the pad clamp the brake disc, causing friction between the brake pad and the brake disc. To reduce the wheel speed, so that the car slows down or stops. [0003] The heat dissipation of disc brakes is better than that of drum brakes, an...
