Technical Field

[0001] The utility model relates to the technical field of casting processing, and more specifically, it relates to a casting sawing device for a master brake cylinder of an automobile. Background Art

[0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with a certain shape, size and performance.

[0003] There are many castings in the production process of existing automobiles. After casting, the castings need to have their risers sawed. Usually, workers use handheld riser separators to separate the risers from the products. This removal method is labor-intensive and has a low degree of automation. If the castings are not firmly fixed, it will cause sawing deviations, which will further damage the castings. The waste generated in the separation process cannot be directly recycled and needs to be collected manually, which increases the workload of the staff and reduces the castings, which is not in line with the concept of sustainable development.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
