Abstract

The invention provides a gravity casting machine of a wheel hub. The gravity casting machine comprises a first bed plate, main driving oil cylinders, stand columns, a second bed plate and a wheel hub mould, wherein the first bed plate and the second bed plate are connected through the stand columns to form a rack; the wheel hub mould comprises a top mould, a lower mould, a left side mould and a right side mould; the lower mould is arranged on the second bed plate; the gravity casting machine further comprises a guide mechanism, a de-molding mechanism, a sealing cover, a sealing cover driving cylinder, a third bed plate and a top mould mounting plate; the upper end of the guide mechanism is connected with free ends of piston rods of the main driving oil cylinder; the lower end of the guide mechanism is connected with the third bed plate; the de-molding mechanism is connected with the third bed plate; and the second bed plate is further provided with a left driving oil cylinder connected with the left side mould and a right driving oil cylinder connected with the right side mould. According to the gravity casting machine of the wheel hub, the top mould can not incline easily, the thickness uniformity of castings is good, the operation is convenient, the labor intensity can be alleviated, the working efficiency is improved, the castings are not easy to damage, the rejection rate can be reduced and the quality of the castings is improved.

Description

technical field [0001] The invention relates to a gravity casting machine, in particular to a hub gravity casting machine. Background technique [0002] The existing gravity casting machine for aluminum alloy wheels includes a machine platform, a top mold, a driving oil cylinder and a wheel hub mold located below the machine platform. The wheel hub mold includes a top mold, a bottom mold, and left and right side molds. The free end of the piston rod of the drive cylinder is connected to the top mold, and the top mold moves down under the action of the drive cylinder to form a casting cavity, and the aluminum water enters the cavity in the mold from the water inlet bucket of the top mold to fill the mold and After cooling and crystallization, after the casting is cast, the cylinder is driven to drive the top mold to move up, and the mold is opened manually to take out the casting. The disadvantages of the existing technology are: the top mold is prone to inclination and devi...
