Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy lost foam casting devices, and in particular to a high-efficiency and energy-saving aluminum alloy lost foam casting device. Background Art

[0002] Aluminum alloy lost foam casting refers to a casting method in which a polystyrene foam plastic pattern is used instead of an ordinary pattern. After the pattern is made, molten metal is poured into it without taking out the pattern. Under the action of the molten metal, the plastic pattern burns, vaporizes, and disappears. The molten metal replaces the space occupied by the original plastic mold. After cooling and solidifying, the desired casting is obtained. In order to make the connection of the molding sand tighter during the casting process, corresponding vacuum equipment is needed to vacuum the casting box to which the molding sand belongs.

[0003] However, as far as the current casting device is concerned, in order to make the connection of the molding sand in the casting box tighter when casting the lost foam, it is necessary to use corresponding vacuum equipment to vacuum the casting box to which the molding sand belongs. When vacuuming, an airtight film will be pre-covered on the inner position of the casting box before filling the molding sand to create a vacuum environment more quickly and thoroughly. However, since it needs manual filling when covering and filling, it is easy to have dead corners and damage during the filling process, making it difficult to ensure that the equipment can be efficient and energy-saving when performing the vacuum operation, and thus there are limitations.
