Precise gravity pressurization casting equipment for automobile hub production

Abstract

The invention relates to a precision gravity pressurized casting equipment for the production of automobile hubs, which includes a main body, a material inlet, a mixing barrel, a mold box, a stirring mechanism, a shaking mechanism, an air pumping unit and a central control mechanism. The stirring mechanism includes a moving components and a stirring component, the stirring component includes a rotating component and a swing component, and the shaking mechanism includes a power component and a shaking component. In the precision gravity pressurized casting equipment used for the production of automobile wheels, the antifoaming agent in the slurry is fully mixed with the slurry through uniform stirring, thereby removing the air bubbles in the slurry and preventing the casting from being caused by the air bubbles in the slurry. When parts are defective, through the shaking mechanism, the slurry can fully contact with all corners of the mold box, preventing the occurrence of sags and fractures caused by insufficient contact with the mold box during the casting process, and improving the quality of the product. Through These greatly improve the practicability and reliability of casting equipment.

Description

technical field [0001] The invention relates to the field of casting equipment, in particular to a precision gravity pressurized casting equipment used for the production of automobile wheel hubs. Background technique [0002] Gravity casting refers to a process in which molten metal is poured into a metal cavity under the gravity of the earth to obtain a casting. Gravity casting equipment generally refers to the equipment that realizes the opening, closing and taking out of metal gravity casting. At present, gravity pressurized casting equipment is widely used in the automobile wheel hub production industry. [0003] However, there are still some problems in the current casting equipment, such as air bubbles inside the cast parts, or incomplete casting and cracks, which all affect the quality of the parts. Although there are currently some casting equipment that remove air bubbles by stirring, this kind of stirring method is single and cannot fully stir to remove air bubb...

[0003] However, there are still some problems in the current casting equipment, such as air bubbles inside the cast parts, or incomplete casting, and cracks, which affect the quality of the parts

Although there are currently some casting equipment that remove air bubbles by stirring, this kind of stirring method is single and cannot fully stir to remove air bubbles, which will still affect the quality of parts. If the problems of air bubbles and parts integrity cannot be solved, the practicality of casting equipment will be greatly reduced. sex and reliability
