Abstract

The invention discloses a protection device for castings, which comprises a casting body, on which a process gas pipe and a process riser are arranged, wherein, the casting body is provided with a process gas pipe and a process riser correspondingly A conical boss, the said conical boss is arranged below the process gas pipe and the process riser. The above protection device for castings can effectively solve the problem of the appearance of castings with meat. When the castings with conical bosses are cleaned after the process air pipe and process riser, due to the protective effect of the conical bosses, the process air pipe and process The meat of the riser band does not affect the appearance of the casting. After the process air hole and the process riser are cleaned, the remaining conical boss can be ground with a grinder. Not only is the structure simple and easy to implement; it can also guarantee the appearance quality of casting products.

Description
