Technical Field
[0001] The utility model relates to the technical field of metal casting, in particular to a casting mold for pouring an aluminum alloy casing of an engine. Background Art
[0002] Metal casting is a process of pouring molten metal into a mold and solidifying it to obtain parts of the desired shape and size. The mold is a key component of metal casting, and its structure, material and design have an important impact on the quality, precision and production efficiency of the casting.
[0003] Traditionally, sand casting is the most commonly used casting method. It uses sand as a mold material, pours molten metal into the sand mold by gravity, and obtains the desired casting after the metal liquid cools and solidifies. In the early 20th century, with the development of casting technology and the demand for industrial applications, metal mold casting gradually emerged. Metal mold casting uses metal (such as aluminum alloy, copper alloy, etc.) as a mold material. Through processes such as pressure casting, low-pressure casting, centrifugal casting, etc., castings with higher precision and surface finish can be obtained. However, in existing metal casting, most of the raw materials will cause waste during casting. Therefore, those skilled in the art provide a casting mold for casting an engine aluminum alloy housing to solve the problems raised in the above background technology.
