Automatic dip-coating machine for sand core coating of brake disc

Abstract

The invention relates to an automatic dip-coating machine for a sand core coating of a brake disc and belongs to the technical field of sand core coatings of brake discs. The automatic dip-coating machine comprises a body, wherein a coating groove and a double shaft air cylinder fixedly connected are arranged at the lower end of the body, the double shaft air cylinder is located on the back side of the coating groove, a fixedly connected servo motor is arranged on the double shaft air cylinder, a slide block is arranged on the servo motor, a slidably connected slide rail is arranged on the slide block, the slide rail is fixedly connected in the body, a rotating shaft is arranged on the servo motor, one end of the rotating shaft is fixedly connected to the servo motor while the other end ofthe rotating shaft is provided with a sand core connector, and the sand core connector is located above the coating groove. A position needed to brush the coating of the sand core of the brake disc is dipped as the servo motor rotates a t a low speed, the depth of the sand core entering the coating groove is adjusted by a limiting switch, the dipping time is controlled by a timer, and the coatingflows into a material pond through an equipment protecting hood to recycle, so that the labor intensity of workers is reduced, waste of the coating is avoided, the production cost is lowered, the production efficiency is improved, and meanwhile, the product quality is ensured.

Description

technical field [0001] The invention relates to an automatic dip coating machine for brake disc sand core paint, which belongs to the technical field of brake disc sand core paint. Background technique [0002] With the market's increasing requirements for product appearance, normal brake disc sand cores can no longer meet customer needs, especially complex sand cores are prone to voids at the corners, resulting in meaty products and affecting product appearance quality. At present, the voids at the corners of sand cores can only It can be eliminated by manual repair or paint immersion. The efficiency of manual repair is low and the cost is high. At present, paint immersion is mostly used to solve the problem of sand core voids. Brake disc sand core coatings are manually soaked with sand cores. After soaking Excess paint will run off or build up on the core, which is wasteful and unintended. Contents of the invention [0003] The present invention aims at the deficiencies...

[0002] With the market's increasing requirements for product appearance, normal brake disc sand cores can no longer meet customer needs, especially complex sand cores are prone to voids at the corners, resulting in meaty products and affecting product appearance quality. At present, the voids at the corners of sand cores can only It can be eliminated by manual repair or paint immersion. The efficiency of manual repair is low and the cost is high. At present, paint immersion is mostly used to solve the problem of sand core voids. Brake disc sand core coatings are manually soaked with sand cores. After soaking There will be excess paint flowing out or building up on the sand core, which is wasteful and does not achieve the desired effect
