Abstract

The invention discloses a low-pressure casting device for aluminum alloy. The low-pressure casting device sequentially comprises a sand box, an electromagnetic stirrer, a heat preservation container, a low-pressure plate and a liquid rising tube from top to bottom; a circular channel is vertically retained in the heat preservation container to connect the heat preservation container with the bottom of the sand box and the liquid rising tube, the upper portion of the heat preservation container is sleeved with the electromagnetic stirrer, and the heat preservation container and the liquid rising tube are sealed by the low-pressure plate in a transition mode. According to the low-pressure casting device, the effects and purposes of fully promoting melt interior flowing, refining melt interior tissue and promoting air exhausting and deslagging by combining an electromagnetic device, melting equipment and low-pressure casting equipment into a whole and utilizing the electromagnetic stirring effect of an electromagnetic field on an aluminum alloy melt.

Description

technical field [0001] The invention belongs to the field of low-pressure casting, and in particular relates to an aluminum alloy low-pressure casting device. Background technique [0002] During the melting and pouring process of aluminum alloy, the step of rotating injection will be carried out, the purpose is to make the gas and slag float up while injecting argon in the melt, which is beneficial to degassing and slag removal. However, the time of this rotary injection is limited, and the influence on the internal structure of the melt is also limited, resulting in low quality of the melt. Contents of the invention [0003] The object of the present invention is to provide an aluminum alloy low-pressure casting device to solve the problem of low melt quality caused by the existing low-pressure casting device. [0004] The technical solution of the present invention is: an aluminum alloy low-pressure casting device, which is characterized in that: from top to bottom, it...
