Description

Technical Field

[0001] The utility model relates to the technical field of motor processing, in particular to a motor seat processing mould for processing dust explosion-proof motors. Background Art

[0002] A dust-proof motor is a motor specially designed to work in a dusty environment. It adopts a series of explosion-proof measures, such as special sealing structure, anti-static coating, anti-spark design, etc., to ensure that no explosion will occur in a dusty environment.

[0003] According to the publication number CN209773393U, a motor seat processing mold is disclosed, which can effectively filter out slag, gas, and harmful elements in the molten metal, meet the appearance and performance requirements of the casting, and effectively avoid the occurrence of problems such as scrapping of the casting. The mold includes an upper mold, a lower mold, and a core. The cavity formed by the upper mold, the lower mold, and the core matches the shape of the motor seat shell. The upper mold is provided with a casting port, which is connected to the cavity through a runner, and the casting port is connected to a pouring cup. A filter is installed in the pouring cup, and the filter is a foam ceramic filter. A filter screen is provided at the position where the pouring cup connects to the casting port, and the filter is installed on the filter screen. A slag discharge pipe is provided on the upper mold, and one end port of the slag discharge pipe passes through the inner side surface of the upper mold to communicate with the cavity, and the other end port of the slag discharge pipe passes through the outer side surface of the upper mold to communicate with external equipment, and a valve is installed between the other end port of the slag discharge pipe and the external setting.

[0004] However, the above device still has shortcomings. When the molten metal fills the mold cavity, the molten metal will be discharged outward along the slag discharge pipe. Impurities such as slag, gas, and harmful elements floating on the upper surface of the molten metal will be discharged from the slag discharge pipe. However, the impurities originally in the mold are discharged from the mold through the floating of the molten metal. The molten metal will overflow, making it difficult to clean the high-temperature molten metal. The overflowed molten metal also poses certain safety risks. Utility Model Content
