[0001] The utility model relates to a low-pressure casting mold, in particular to a low-pressure casting mold for an integrated motor housing, and belongs to the technical field of low-pressure casting molds. Background Art
[0002] Low-pressure casting is a casting method in which liquid metal fills the mold cavity under pressure to form a casting. This method is usually carried out above a sealed crucible. Compressed air is introduced to create a low pressure (0.06-0.15MPa) on the surface of the molten metal, causing the molten metal to rise through the riser to the interior of the casting mold and fill the mold. The pressure is maintained until the casting is completely solidified. After the casting solidifies, the casting mold will open and the cast casting can be removed from the casting mold. Motor housings can be produced by low-pressure casting.
[0003] However, traditional low-pressure casting molds will produce some harmful gases after being opened. These gases will float directly into the air, which can easily be inhaled by operators and cause damage to the operators' bodies. At the same time, they can easily pollute the surrounding environment, resulting in low safety and environmental protection. Utility Model Content
